About Us

Connecting supply chains across borders

TransHarbor Trading Limited is a Hong Kong-based international trading company — sourcing electronic products, trading metals, energy and agricultural commodities, and supplying construction machinery to customers worldwide.

Who We Are

A trading house built around reliability

We combine deep sourcing expertise in electronic products with active trading across metals, energy and agricultural commodities, and strong supplier relationships in construction machinery. Our team works with manufacturers, suppliers and buyers at every stage — from specification and quotation to contracting, inspection and delivery.

The name TransHarbor reflects what we do: goods and partnerships that move across ports, borders and markets — reliably, and under your brand.

We are organized as a multi-desk trading house rather than a single-commodity broker. The electronics desk sources components, communication chips, networking equipment and servers, and runs our white-label ODM/OEM program for customers who want their own hardware brand without building a factory. The metals desk trades electrolytic copper, electrolytic aluminum, high-purity metals and precious metals against the international benchmarks. The energy desk handles crude oil, LNG and LPG, refined fuels and petrochemical feedstocks. The agriculture desk moves wheat, soybeans, corn and vegetable oils. And the machinery desk supplies mining machinery, excavators, cranes, loaders and haul trucks. Each desk operates with its own specialists and its own documentation standards, but they share one contract discipline and one client relationship.

That structure matters to our customers. When a buyer works with TransHarbor, they deal with a counterparty that understands their industry — the specifications that matter, the inspection regime that protects both sides, the payment structures their market uses — rather than a generalist who learns the business from the first invoice. Our teams are multilingual and operate across the time zones of the markets we serve, which is why a question asked in the morning can receive a documented answer the same day, wherever the cargo sits.

Quality and compliance are managed as one discipline, not two. Every product family has defined inspection procedures, from batch-level checks on electronic components and independent analysis of metals and grains, to condition surveys on machinery and quantity and quality inspection on energy cargoes. Documentation is prepared to the standard your bank, your customs authority and your own quality department expect: certificates of analysis, weight certificates, inspection reports, origin documents and insurance papers, issued and reconciled before payment moves.

Logistics is where the details decide the outcome. We coordinate the transport chain for each product family — consolidated air and sea freight for electronics, container and breakbulk programs for metals, vessel and barge movements for energy, bulk and container shipments for grains, and low-bed, RoRo and breakbulk arrangements for heavy machinery. Every shipment carries a documented chain from our supplier to your door, and our operations team tracks it through the ports, borders and customs processes that separate a smooth delivery from a delayed one.

Underpinning all of this is a simple belief: a trading company earns its margin once, but earns its relationship with every shipment. We are registered and regulated in Hong Kong, a jurisdiction whose trading standards are recognized worldwide, and we run our business so that our counterparties — suppliers, buyers, banks and inspectors — always know where they stand. Whether you are sourcing a single component or contracting a year of supply, you will find the same structure, the same documentation and the same accountability.

Our Services

One partner, door to door

From the first consultation to after-sales support, TransHarbor manages the entire international trade journey — business consultation, procurement management, international settlement, transport and after-sales service under one roof.

End-to-End Services at a Glance

TransHarbor Trading Limited was built around a simple observation: most friction in international trade does not happen inside a single step, it happens between steps. A product can be sourced perfectly and still be delayed by a letter of credit that does not match the documents, or a machine can be built to specification and still arrive late because nobody planned the heavy-lift discharge. That is why we sell services, not just products. Our team takes responsibility for the whole chain — consultation, procurement, settlement, transport and after-sales — and manages the seams between them so that nothing falls between two desks.

The journey begins with business consultation. We help buyers define their requirements, understand the market basis for pricing, choose the right product specification, and structure a deal that matches the commercial and regulatory environment of their country. Our desks speak the language of their industries — electronics, metals, energy, agriculture and heavy machinery — so the advice we give is practical rather than generic. This is followed by procurement management: we qualify suppliers, negotiate terms, place orders against agreed specifications, and inspect production or cargo before it ships, so that the quality your contract promises is the quality that actually leaves the port.

Once the goods are contracted, our international settlement team takes over. We prepare and check the full set of trade documents — commercial invoices, packing lists, bills of lading, certificates of analysis, insurance papers and certificates of origin — and manage payments through letters of credit, documentary collections, telegraphic transfers and bank guarantees with a network of banks that know our business. Because settlement is handled by a dedicated team with its own banking relationships, buyers and sellers are protected on both sides of the transaction: the seller ships against documents that will pay, and the buyer pays against documents that will deliver.

Transport and logistics are coordinated by our operations team for every product family — consolidated air and sea freight for electronics, container and breakbulk programs for metals, vessel and barge movements for energy, bulk and container shipments for grains, and low-bed, RoRo and heavy-lift arrangements for machinery. Where cargoes are non-standard — oversized, overweight, or simply built without a container in mind — our special transport service plans the entire route, from the factory floor in one corner of the earth to your site in another. After the cargo arrives, after-sales service keeps the relationship working: documentation is reconciled, spare parts or replacements can be arranged, quality issues are investigated with the supplier, and the next order starts from a record of what went well.

Every service on this page can be used separately or combined into a single door-to-door program. Buyers who use the full chain get one contract, one counterparty and one point of accountability; buyers who use a single service get specialists who understand exactly how their part of the chain connects to the rest. Either way, the standard is the same — documented, inspected, insured and delivered the way it was promised.

Settlement Built for International Trade

In cross-border trade, the payment is not a single transaction — it is a chain of documents, dates, banks and obligations that must align exactly, or the goods stop moving. TransHarbor operates a dedicated international settlement team whose only job is to make that chain work. Settlement is treated as a service in its own right, not an administrative afterthought of the sales desk, which is why our clients can rely on it even when they buy from us only a single cargo or a single machine.

Our settlement capability is built on strong, long-standing relationships with banks. We work with major international banks and leading Chinese and Asian banks, maintaining accounts, credit lines and documentary facilities that allow us to open and receive letters of credit, issue guarantees, and support trade finance arrangements for the counterparties we contract with. These relationships matter in practice: a letter of credit from our bank is taken seriously by sellers around the world, a guarantee issued on our account is honoured without hesitation, and when a client needs the transaction structured in a particular way — a transferable credit, a back-to-back arrangement, a revolving facility — we can usually find the bank and the product that makes it work.

The settlement team itself is independent and specialised. It handles the complete range of instruments used in our trade: irrevocable letters of credit, confirmed and unconfirmed; documentary collections under D/P and D/A terms; telegraphic transfers and wire instructions across all major currencies; bank guarantees and standby letters of credit for performance and advance-payment obligations. The team prepares and examines every document in the set — commercial invoice, packing list, bill of lading, certificate of analysis, insurance certificate, certificate of origin — checking them against the terms of the credit or contract before they reach the bank. Discrepancies are caught and corrected on our side, not returned by the bank at the cost of a delay; presentation dates are managed so that payment is achieved within the validity of the credit.

Beyond the mechanics, the team advises on the structure itself. For a new buyer, we may recommend a confirmed letter of credit or a collection with an inspection certificate, so that both sides are protected while trust is being built. For an established relationship, we may move to open account terms with a bank guarantee, improving cash flow for the buyer without removing the seller's security. For sellers who need working capital, we can arrange financing against export documents or receivables. Because our settlement desk sits inside a trading company, it understands the cargo behind every payment — it knows what a steel coil, a server rack, a crude cargo or a haul truck needs in its documentation, and it applies that knowledge to every presentation.

The result is a settlement service that reduces risk on both sides of the deal. Sellers ship knowing that compliant presentation will pay; buyers pay knowing that payment releases control only through documents that prove the shipment. Multi-currency, multi-bank and multilingual, the desk operates across the time zones of our markets, so a document issue raised in the morning is answered the same day. For buyers who want a single counterparty that can source, ship and settle, this is the service that ties the trade together.

Special Transport

From any corner of the earth to your door — moving oversized, overweight and non-standard products that no container can carry, with route surveys, heavy-lift planning and multi-modal delivery.

Moving What Others Cannot

Most freight in the world moves in a container, on a pallet or in a hold — but a meaningful part of international trade does not. Mining shovels, crawler cranes, transformers, generators, complete production lines and machinery rebuilt for a second life are too large, too heavy or too oddly shaped for standard transport. TransHarbor's special transport service exists for exactly these cargoes. Our promise is deliberately simple: we will collect a non-standard product from any corner of the earth and deliver it to the customer's site, wherever that site is, however many borders it crosses on the way.

The service starts where every difficult move starts — with the physical facts of the cargo. Dimensions, weight, centre of gravity, lifting points and handling constraints are documented before a single transport decision is made. From those facts our operations team builds the route. Where a cargo travels by road, the route is surveyed for bridge weight limits, height restrictions, narrow sections and turning radii, and escorts and permits are arranged with the authorities along the way. Where it must cross water, we select the vessel that fits the job — a flat-rack or open-top container where possible, a breakbulk vessel, a roll-on/roll-off carrier or a deck barge where the size demands it — and where sea and road meet, heavy-lift cranes or floating cranes handle the transfer at the port.

Multi-modality is the heart of the service. A machine built in a factory in the interior of one country may travel by low-bed trailer to a railhead, by rail to a river port, by barge to a seaport, by heavy-lift vessel across the ocean, and by special road convoy from the destination port to the final site. Each mode change is planned as its own operation, with the lifting gear, the trained rigging crew and the correct equipment staged at the transfer point before the cargo arrives. Our team coordinates the whole sequence as one project, not as a series of separate shipments, which is why we can commit to an arrival date that other forwarders call unpredictable.

Special transport also carries its own paperwork. Oversized cargo requires special permits, route approvals and often escort arrangements in multiple jurisdictions; export and import declarations must describe the cargo accurately enough for customs to release it; and insurance must cover the value, the route and the handling methods involved. We prepare these documents as part of the service, working with the customer's own customs brokers where required, so that the cargo does not sit at a border waiting for a paper that was forgotten. Every movement is insured for its full value, and every operation — loading, lashing, sea passage, discharge and road delivery — is carried out by qualified contractors who understand heavy cargo.

Our special transport desk has moved the kind of equipment that defines projects: mining machinery and large excavators, mobile and tower cranes, transformers and power equipment, industrial plants relocated in pieces, and the spares and tooling that keep them running. Whatever the non-standard product is, the starting point is the same — tell us what you need to move, where it is and where it must go, and our team will plan the route, quote the cost and deliver it to your door. From any corner of the earth.

Wheat field with a combine harvester at dusk

The Division at a Glance

The agricultural division of TransHarbor Trading Limited supplies the grain, oilseed and vegetable oil products that sit at the base of the food and feed chain. Our product families — wheat, soybeans, corn and vegetable oils — are traded in volumes large enough to feed mills, crushers, feed compounders, bakeries and edible-oil packers, and our job is to make sure the cargo matches the specification on arrival, not just on the offer sheet.

Pricing follows the international benchmarks of the grain market. Wheat, corn and soybeans are quoted against the Chicago Board of Trade futures, the reference of the global trade, with the freight and quality basis made explicit in every offer; vegetable oils are priced against the regional and international markets for each oil, including palm, soybean and rapeseed. We state the basis, the quality and the delivery terms in writing, so a buyer knows exactly what the number on the offer represents.

Quality in agricultural trade is defined by a small set of parameters that decide how a cargo can be used: moisture content, protein, test weight, foreign matter, damaged kernels and, for the products that require it, mycotoxin levels. Every offer carries these figures, every shipment is sampled and analyzed against them, and the analysis is performed by laboratories and surveyors whose reports your market accepts. The certificate of analysis travels with the cargo, not behind it.

Logistics are managed around the perishability of the product. Grain moves in bulk vessels and containers, with moisture management, ventilation and fumigation handled according to the voyage and the season; vegetable oils move in flexitanks, ISO tanks and drums, with temperature and contamination controls appropriate to the oil. We schedule against the harvest calendar, the freight market and your consumption pattern, and we flag the risks — weather, port congestion, shipping availability — early enough for you to plan around them.

Seasonality is central to how we structure business. Some buyers need protection across the crop year; others want to buy opportunistically when the market offers value. We support both: term programs with scheduled shipments that keep your silos and tanks full, and spot transactions when the price is right. In both cases the operating standards are identical.

If you buy grain, oilseeds or vegetable oils on a recurring basis, send us your specification, your delivery cadence and your target ports — we will come back with a program, not a brochure.

Traceability is a growing requirement in food and feed supply chains, and our documentation reflects it. Every cargo carries the analysis certificates, origin documents, phytosanitary paperwork and, where your market requires it, the traceability records that let you answer the question your customers ask: where did this come from, and what is in it? We also keep current on the import rules, quality standards and tariff treatments of the destinations we serve, so the advice we give about a program is grounded in what the port will actually accept.

Whatever the size of your program — a single trial parcel or a year-round schedule — the agricultural desk holds the same operating standard: a specification that is written down, an inspection that is independent, and a shipment that arrives the way it was contracted. That is the basis on which we ask to be measured, and it is the basis on which our customers keep coming back.

Wheat grains poured from a sack
Product 01

Wheat

TransHarbor supplies wheat in the two commercial families the market distinguishes: milling wheat for flour and food production, and feed wheat for animal nutrition. Within each family we trade the grades your market recognizes — by protein content, test weight and moisture — and we quote cargoes against the international benchmark with the quality parameters stated cargo by cargo.

Milling wheat is the specification-critical product. Flour mills select wheat by protein, gluten quality and moisture, and a cargo that misses the specification can disrupt a production week rather than just a contract. Our milling wheat program carries the full analysis — protein, moisture, test weight, falling number, foreign matter and damaged kernels — and we source to your required profile rather than offering whatever is available and calling it close enough.

Feed wheat is traded on a simpler but no less real specification: moisture, test weight and the absence of the contaminants that matter to feed safety. It moves in larger, faster parcels, and our role is to match the quality to the compounder's ration program and the price to the market, with the documentation — analysis certificates, origin and phytosanitary documents — prepared for the destination market.

Delivery is arranged by bulk vessel for large programs, by container for flexible parcels, and with the storage and fumigation handled according to the season and the voyage. We can support mills and compounders with scheduled programs that keep the intake steady, and spot buyers with the parcel that matches their immediate need.

Sourcing is managed across origins and seasons. We monitor the harvest programs, the export availability and the freight markets of the origins we trade, and we use that visibility to advise buyers on timing — when to contract, when to wait, and how to protect the price of a program that spans the crop year. Every cargo is traceable to its origin and its analysis, so the documentation answers the questions your customers and your auditors will ask.

Milling & feed gradesProtein-specifiedBulk & containerCertified analysis
Soybeans in a wooden scoop
Product 02

Soybeans

Our soybean program supplies whole beans to crushers, feed compounders and food processors, sourced from the major exporting origins and traded against the international benchmarks that set the price of the global soybean complex. The cargo specification — moisture, foreign matter, splits, damage and oil/protein content — is stated in every offer and verified at load and discharge.

The principal buyers in this market are the crushers. For them, the value of a cargo is the value of the meal and the oil it yields, so we quote the parameters that drive that yield — protein and oil content — alongside the shipping-quality measures that protect the cargo in transit. Crushers planning a campaign need consistent intake, and our program structure supports scheduled arrivals rather than opportunistic one-offs.

Feed and food buyers use soybeans on different specifications, and we handle both. Feed-grade programs focus on the factors that protect feed safety and digestibility; food-grade programs, where they exist in your market, carry the stricter tolerances for damage, foreign matter and handling that the buyer's process requires.

Inspection and logistics follow the grain division standard: independent sampling and analysis, moisture management during the voyage, and documentation — including phytosanitary certificates and origin documents — prepared for the destination. Whether your need is a single cargo or a program across the crop year, the soybean desk quotes against your specification and your delivery window.

Quality management starts before the vessel is booked. We qualify the origins and the suppliers we buy from, define the specification and the sampling protocol in the contract, and hold the cargo to that standard through load, voyage and discharge. When a quality parameter moves — as it can with a natural product — the deviation is identified and communicated at the point where it can be managed, with the options and the documentation presented together rather than discovered later.

Corn

TransHarbor supplies corn for the two markets that consume most of the world's crop: the feed industry and the industrial processors that convert corn into starch, sweeteners, ethanol and other derivatives. The same kernel serves both, but the specification differs by application, and we source accordingly.

Feed-grade corn is traded on moisture, test weight and foreign matter, with the quality profile that keeps a ration consistent from batch to batch. We support feed compounders with scheduled deliveries that match their consumption, and trading partners with the parcels and grades their market demands. Consistency matters more than a one-off bargain: a compounder who must reformulate because a cargo came in off-spec loses more than the price difference on the load.

Industrial buyers take corn on the parameters that matter to their process — starch yield, moisture control for dry milling, and the general quality that keeps a plant running. For these buyers we quote the specification the process needs, arrange the delivery mode that fits their intake — bulk vessel, container or truck — and manage the documentation for import and customs.

Quality control follows the grain standard: representative sampling, analysis against the contract specification, and the certificate that travels with the cargo. Storage and handling are managed to protect moisture and quality from load to discharge, whatever the season and the voyage.

The corn desk stays close to the markets that set the price. We quote against the international futures and the regional cash markets, and we track the demand from the feed, starch and ethanol sectors that compete for the same crop — because that competition, not the headline price, is what determines whether a cargo is good value in your market on your delivery window. That context goes into every offer, alongside the specification and the freight.

Vegetable oil with wheat and soybeans
Product 04

Vegetable Oils

The vegetable oil program supplies soybean oil, palm oil and rapeseed oil in the commercial forms the market trades: crude and refined, in bulk and in packed form, for the food industry, the oleochemical sector and the biofuel market. Each oil is defined by its specification — free fatty acid, moisture and impurities, iodine value, color — and priced against its own market.

Palm oil is the volume product of the family, traded in its crude and refined, bleached and deodorized forms, and used across food, oleochemicals and energy. We supply RBD palm olein and stearin for food and industrial use, and crude palm oil for processors, with the quality parameters that each application requires and the logistics — ISO tanks, flexitanks, tank containers — matched to the destination.

Soybean oil and rapeseed oil serve the food and biofuel markets with different specifications. Food buyers need refined oil with stable quality and clean handling; biofuel producers buy against the parameters of their process and their certification requirements. We quote both, and we manage the storage and transport so the oil arrives in specification, not just on paper.

Inspection is arranged by independent surveyors at load and discharge, with quantity and quality certificates issued to banking standard. For buyers running continuous programs — bottling plants, food manufacturers, oleochemical producers — we can structure scheduled supply that keeps the tanks turning without overstocking capital in inventory.

The vegetable oil program is supported by the same market discipline as the rest of the division. We monitor the palm, soybean and rapeseed markets, the freight and the tank logistics that move the product, and we share that view with buyers so the timing of a purchase is a decision made on information, not on habit. For each program we maintain the specification records, the inspection reports and the documentation set that your quality team and your customers expect.

Energy Products

Crude oil, LNG and LPG, refined fuels and petrochemical feedstocks — contracted, inspected and delivered against the international pricing benchmarks that govern each cargo.

Oil tanker at port at dusk

The Division at a Glance

The energy division of TransHarbor Trading Limited trades crude oil, liquefied gas, refined fuels and petrochemical feedstocks for a customer base that spans refineries, trading houses, fuel distributors and industrial consumers. Energy cargoes are large, specification-sensitive and schedule-critical, which is why every transaction is built around three disciplines: market-based pricing, independent inspection and banking-grade documentation.

Pricing is anchored to the benchmarks your market recognizes. Crude is quoted against Brent, Dubai or the regional marker applicable to the grade; refined products are priced against Platts assessments and the regional product benchmarks — including MOPS for the Asian gasoil and fuel markets; and LPG is quoted against the published contract prices of the major producers. We state the basis, the period and the premium or discount explicitly in every offer, so there is no ambiguity about how the final price is derived.

Quality control on energy cargoes is carried out by the industry's own instruments. Every parcel is defined by its specification sheet — API gravity, sulfur content, distillation curve, flash point, density and the other parameters that determine how the product can be used and where it can be delivered. Independent inspection, performed by the internationally recognized firms at load port and discharge port, verifies both quantity and quality, and the reports become part of the transaction record.

Logistics and scheduling are where energy trading is won or lost. We coordinate vessel nomination, laytime management, storage and blending where the deal calls for it, and the full chain of transfer documentation — bills of lading, quantity and quality certificates, and customs paperwork. Because a day of vessel delay can erase the margin on a cargo, our operations desk treats the schedule as part of the contract, not a detail to be managed later.

Compliance is a precondition, not a courtesy. Export and import requirements, licensing, sanctions screening, vessel checks and end-use considerations are reviewed before we commit to a transaction, and the trade-finance documentation is prepared to banking standard so that letters of credit, guarantees and payment instruments move without dispute.

From a single cargo to a monthly program, the energy desk quotes on the basis you need — CFR, CIF, FOB or DAP — with the inspection regime, the documents and the payment structure agreed in writing before any value moves.

Market intelligence is part of the service. Our traders monitor the benchmarks, the freight markets, the refinery maintenance calendar and the supply-demand signals that move prices, and we share that view with our counterparties honestly — including when the market is telling you to wait. Because energy transactions are large and fast, our documentation and payment structures are designed for the speed of the market: offers that are complete, contracts that are bankable, and an operations desk that treats the laytime clock as seriously as you do.

For counterparties building a long relationship, the desk also supports forward planning — contract programs, storage strategies and the market review that turns a series of transactions into a supply plan. Energy is a relationship business carried out in cargo-size steps, and that is how we run ours.

Crude Oil

TransHarbor trades crude oil across the grades that move through the international market — from the lighter sweet crudes that suit simple refineries to heavier and medium-sour grades that feed complex conversion capacity. Our program covers cargoes of standard export grades, including the major Russian and regional streams handled through established trading channels, each defined by its assay and priced against the appropriate marker.

Every crude parcel is specified before it is offered. The assay covers density, sulfur, TAN, distillation yields and the other parameters your refinery planning team needs, and we match grade to buyer: a refiner configured for light sweet crude is not offered a heavy sour cargo, however attractive the discount looks in a headline number.

Inspection is standard practice. Quantity is established by vessel gauging and shore tank reconciliation, quality by representative sampling and laboratory analysis against the assay and the contract specification, and the results are witnessed by an independent inspector at both ends of the voyage. This protects both parties from the disputes that destroy energy-trade relationships.

Delivery terms are structured to the transaction: FOB at load port for buyers with their own logistics, CFR or CIF for delivered purchases, with vessel nomination, laytime and demurrage terms spelled out in the contract. Payment is typically structured against documents — letters of credit, DLCs or bank guarantees — and we can support structured or prepayment arrangements where the counterparty profile justifies them.

Market intelligence is part of the crude program. Our traders monitor the benchmark spreads, the freight market and the supply-demand signals that move prices, and we use that view to advise buyers on timing and structure — when to fix a cargo, how to manage the exposure between quote and load, and what the alternatives look like when a grade or a window does not fit. The advice is grounded in the same data that sets our own offers, so what you hear from us is what you can test against the market.

LNG & LPG

Our liquefied gas program covers LNG — liquefied natural gas delivered against the international contract and spot markets — and LPG in both of its principal streams: commercial propane and butane, supplied separately or as a mixed product according to your specification. These are different products with different logistics, and we structure each transaction on its own terms.

LNG business is characterized by large cargoes, long-term contracts and a small group of well-documented market participants. We support buyers who need supply security through term deals, and buyers who want to optimize against the spot market with individually priced cargoes. Every LNG transaction is defined by the cargo specification, the delivery window, the vessel and the pricing formula, and we prepare the documentation set that financing and regasification planning both require.

LPG moves in smaller, more flexible parcels — pressurised vessels, refrigerated carriers and, at the consumer end, cylinders and bulk tanks. We supply LPG to distributors, industrial gas users and petrochemical consumers, matching the product specification — propane/butane ratio, vapor pressure, sulfur — to the end application, and managing the transport and handling chain so the product arrives in specification.

Both programs share the same operating standards: independent inspection of quantity and quality, clear allocation of demurrage and laytime risk, and full documentation for customs, payment and your own records. Whether your need is a single LNG cargo or a monthly LPG program, we quote on the basis, the window and the payment terms that fit your operation.

Safety and operational integrity are treated as contractual matters. Vessel selection, terminal compatibility, cargo handling procedures and the safety documentation that ports and regulators require are reviewed before a program is committed, and we support buyers with the technical paperwork — cargo specifications, MSDS and handling guidance — that their own safety and compliance teams need. In a product family where a misdescribed cargo can stop a terminal, the documentation is part of the product.

Gasoline & Diesel

TransHarbor supplies refined fuels for the wholesale market — gasoline in the grades traded in your region, and automotive gasoil (diesel) in the sulfur grades the market demands, including the low-sulfur 10ppm and 50ppm specifications that dominate modern fuel standards. Product is sourced from refineries and major suppliers with the specification sheets, and delivered against the regional price assessments that govern each market.

Fuels are defined by their specification, and our offers state the full parameter set: density, sulfur content, distillation, cetane or octane index, flash point and the other properties that determine both legality and performance in your market. Where your storage or blending operation needs a specific quality, we source to that requirement rather than offering whatever the origin happens to produce.

Quantity and quality are verified independently at load and discharge. Shore tank and vessel measurements are witnessed and reconciled, and samples are analyzed against the contract specification so that any deviation is identified and resolved at the point where it matters — not after the cargo has been accepted and blended away.

Delivery can be structured by ocean tanker, barge, pipeline or truck, depending on the destination and the parcel size, and we manage the transfer documents, customs formalities and tax compliance that wholesale fuel movements require in each jurisdiction. For distributors we can also support storage programs with scheduled replenishment so that your tanks stay full without tying up capital in speculative stock.

Quality assurance follows the same standard as the rest of the division. Each parcel is sampled and analyzed against the specification at load, and the results are reconciled with the supplier documentation before release; where your market or your contract requires it, independent inspectors witness the operations and issue the certificates your records need. For buyers with blending or storage operations, we can also advise on the quality program — which tests to run, which tolerances to enforce and how to keep the documentation aligned with the product that actually enters your tanks.

Naphtha & Refined Products

The refined products program completes the energy division with the feedstocks and by-products that keep downstream industry running: naphtha in its light and heavy fractions, used by petrochemical crackers and as a gasoline blending component; fuel oil for marine bunkering and industrial combustion; and the range of refined streams that sit between the headline products — including gasoil fractions, condensate and other intermediate materials.

Naphtha is the most specification-sensitive product in this family. Crackers select feedstock by its paraffin, naphthene and aromatic content, and our offers carry the full analysis — density, boiling range, P/N/A composition, sulfur and water content — so a buyer can match the cargo to the cracker configuration without guesswork. For blending applications we quote the properties that matter to the blender.

The rest of the refined range is supplied on the same principle: specification first, price against the benchmark, inspection by independent surveyors. Marine fuel is delivered to the sulfur specifications applicable in the trading area, industrial fuel and condensate are matched to the buyer's storage and combustion equipment, and every product ships with the documents that ports, customs and your counterparties require.

Because this product family is diverse, our role is often advisory as well as commercial: we help buyers identify the right grade, the realistic specification and the efficient logistics for their market, and then execute the transaction with the same operational discipline as the rest of the division.

Supply reliability is the foundation of the program. We maintain relationships with refiners and producers, track the availability of each stream through the market cycle, and keep alternative sourcing options identified for every product we quote — so when a primary source tightens, the response is a re-quote and a plan, not a delay and an apology. For buyers running continuous processes, this continuity is worth more than the price advantage of any single cargo.

Metals

Electrolytic copper, electrolytic aluminum, high-purity metals and precious metals — supplied with certified quality, clear specifications and delivery programs built around your production schedule.

Copper, aluminum and gold bullion

The Division at a Glance

The metals division of TransHarbor Trading Limited moves refined and semi-finished metals for two kinds of customers: manufacturers who need assured raw material for their production lines, and trading partners who need a counterparty that can structure, inspect and deliver physical metal on commercial terms. Our four product families — electrolytic copper, electrolytic aluminum, high-purity metals and precious metals — cover the range from bulk industrial metal to specialist materials with demanding purity specifications.

Pricing follows the market in a transparent way. Base metal prices are anchored to the international benchmarks — LME for copper and aluminum, with regional reference to SHFE where that suits the transaction — and the commercial premium is agreed up front so that both sides know exactly what the delivered price represents. We work on fixed-price contracts, formula-based pricing and spot offers, matching the structure to your purchasing rules rather than forcing you into ours.

Quality is established by inspection, not by reputation. Shipments are weighed, sampled and analyzed against the specification in the contract, and independent third-party inspection — by firms such as SGS, Bureau Veritas or CCIC — can be arranged at load port, discharge port or both. The documentation package, including the certificate of analysis, weight certificate, origin documents and insurance papers, is prepared to banking-standard detail so that your letter of credit and customs clearance are not held up by missing paperwork.

Logistics for metal is a specialist discipline. We arrange containerized and breakbulk shipments, coordinate warehousing and blending when your program requires it, and structure incoterms and payment terms — from CFR and CIF to FOB, DAP and DDP — to fit the transaction. Insurance, fumigation where required, and full traceability from load port to discharge are part of every program we run.

Compliance is handled without drama. Export and import documentation, origin certification, tariff classification and any sanctions or end-use screening applicable to the transaction are reviewed before we commit to a shipment, not after the vessel has sailed. This is the difference between a metal trader that ships cargo and a trading partner that protects your license, your reputation and your delivery schedule.

Whether you are buying monthly tonnage on a long-term framework or covering a single urgent cargo, the metals desk can quote against your specification, your delivery window and your payment requirements.

The desk also earns its place by telling you what the market is doing. Our trading team tracks the benchmarks, the premiums and the freight markets that drive delivered prices, and we use that visibility to advise buyers on timing, structure and risk — when to fix, when to float, and how to protect the price of a cargo that has not yet been contracted. Every recommendation is grounded in the same market data that sets our own offers, and every contract we conclude is governed by the terms, the inspection regime and the dispute provisions that your side of the market recognizes.

Above all, the metals desk is built for long relationships. Metal programs run for years, not transactions, and we structure ours so that both sides can plan: agreed specifications, transparent pricing bases, predictable documentation and a counterparty that answers the phone when a cargo is on the water.

Stacked electrolytic copper cathodes
Product 01

Electrolytic Copper

TransHarbor supplies electrolytic copper cathodes of LME Grade A quality, typically 99.99% copper content, produced by established smelters and refineries. Cathodes are supplied in standard dimensions and weights, packed in the conventional strapped bundles, and accompanied by the refiner's certificate of analysis and full traceability to the production lot.

Our copper moves into the industries that build the modern economy: cable and wire manufacturers drawing rod and wire for power transmission, transformer and motor producers, tube and sheet mills, and manufacturers of electrical components and printed circuit board raw materials. Because cathode quality directly affects downstream processing, we keep specification consistency as the first requirement of every purchase — the chemistry, the surface condition and the packing must meet the contract, cargo after cargo.

Inspection is arranged at the load port as standard. Weights are verified, cathodes are sampled and analyzed by an independent laboratory, and the results are reconciled against the refiner's certificate before release. Where your contract requires SGS, BV, CCIC or another named inspector, we manage the appointment, the sampling protocol and the reporting so that the documents arrive in your hands before the vessel does.

Delivery is structured around your cash flow and your production intake: containerized lots for flexible scheduling, breakbulk parcels for larger tonnage, and warehousing options when you need to build stock ahead of a campaign. Payment can be structured against documents or on a letter of credit, and we are equally comfortable selling one container or a multi-thousand-tonne program.

Pricing transparency is built into every offer. We quote the LME reference, the premium and the freight element separately, so your finance team can see exactly what each part of the delivered price represents and can hedge the market exposure that sits behind it. When the market moves between quotation and confirmation, we re-quote on the same transparent basis rather than leaving you to discover the adjustment in the final invoice.

Stacks of electrolytic aluminum ingots
Product 02

Electrolytic Aluminum

Our electrolytic aluminum program covers standard remelt aluminum ingots in the widely traded purities — typically 99.7% and above — as well as T-ingots and sows where the application calls for them. Material is sourced from primary smelters and major suppliers, cast to specification, and shipped in the standard strapped bundles with certificate of analysis for each lot.

Aluminum from this desk feeds extrusion plants making profiles and sections, rolling mills producing sheet and foil, die-casting foundries, and the power transmission sector that consumes aluminum for conductors and busbars. We keep the specifications that matter to each downstream process — alloy chemistry, impurity limits, ingot dimensions and surface quality — as the controlling parameters of every order, not optional extras.

Quality control follows the same discipline as the rest of the metals division. Chemical composition is verified by independent analysis against the contract specification, ingot weights are checked at load, and packing is inspected to make sure the cargo travels without damage and can be discharged and stored efficiently at your end. Full documentation — analysis certificate, weight list, origin and insurance documents — is issued for banking and customs purposes.

We quote flexible tonnage: single containers for urgent fill-in, full truck or container programs for steady supply, and long-term framework contracts with scheduled releases for smelter-scale users. Price structures can be fixed, or indexed to LME with an agreed premium, whichever fits your purchasing policy.

The aluminum desk also works with buyers on the specification decisions that protect their process — matching ingot purity and alloy chemistry to the casting or extrusion route, advising on lot sizes and packing that suit your furnace layout, and flagging the seasonal factors that affect supply before they affect your schedule. Whether you are a foundry, an extruder or a trading house, the same discipline of specification, inspection and documentation applies to every ton we ship.

High-purity copper powder and sputtering target
Product 03

High-Purity Metals

For applications where standard commercial grades are not enough, TransHarbor supplies high-purity metals in the 5N, 6N and 7N ranges — including high-purity copper powder and granules, aluminum, silver, tin and other specialty metals. These materials are produced by specialist refiners under controlled conditions and are shipped with full analytical certification covering the critical impurities that matter for your process.

The customers for this program are the demanding end of the materials market: semiconductor and electronics manufacturers using sputtering targets and electronic-grade pastes, powder metallurgy and additive manufacturing operations that need consistent particle size and chemistry, catalyst producers, and research institutions with tightly defined material specifications. Purity is not a marketing number here — it is a process parameter, so we treat the certificate of analysis as a contractual deliverable and reconcile it before shipment.

Handling and logistics are adapted to the material. High-purity powders are packed in sealed containers under inert atmosphere where the product requires it, with batch-level traceability, shelf-life management and storage conditions that protect the specification from the moment of dispatch. Particle size distribution, oxygen content and metallic impurity profiles are documented to the level your application demands.

Volumes range from laboratory quantities to production-scale lots, and our sourcing network can usually match an alternative qualified supplier when a primary source is on allocation. If your specification is unusual, send us the analysis sheet — if we can source it, we will quote it with the documentation attached.

Because high-purity materials are often qualified into a process and then re-ordered for years, we treat continuity as part of the product. Qualified lots are kept traceable to the batch, repeat orders are matched to the same specification window, and any change in the source or the analysis is disclosed to you before shipment rather than discovered at your incoming inspection. This is the difference between buying a material and maintaining a specification.

Precious Metals

TransHarbor's precious metals desk handles gold, platinum, silver and palladium in the forms that industry and finance actually use: bullion bars, ingots, grains and, where applicable, refinery sponge. Material is sourced from reputable refiners and suppliers with documented provenance, and every transaction is supported by assay certificates and the full paper trail that responsible dealing requires.

Our precious metals customers fall into two groups. Industrial buyers — electronics manufacturers, plating operations, catalyst producers and jewelry manufacturers — need material with consistent fineness and reliable delivery against production schedules. Institutional and trading buyers need a counterparty that can structure the transaction, handle logistics and custody properly, and provide documentation that satisfies their own compliance departments.

Verification is at the heart of the program. Material is weighed and, where appropriate, assayed by fire assay or instrumental analysis against the declared fineness; the assay result is reconciled with the supplier's certificate before value moves. We work with refiners and assayers whose certificates are recognized by your side of the market, so the paperwork closes the loop rather than creating a dispute.

Given the value density of precious metals, compliance is treated as a delivery requirement. Know-your-counterparty checks, origin verification, transport security and insured custody are built into every transaction, and we can quote delivered terms that keep the material insured from the moment it leaves the refinery to the moment it reaches your vault or your factory gate.

The desk also structures the commercial side of the transaction to suit the market — fixing prices against the international benchmarks, agreeing the premium or the financing cost explicitly, and preparing the settlement documents that your treasury and your auditors expect. Whether the metal is for a production program or a portfolio position, the transaction is executed with the same standard: a clear specification, an assay that supports it, and a paper trail that closes the loop.

Electronic Products

From discrete components and communication chips to complete networking gear and servers, TransHarbor supplies the full electronics stack — sourced from established manufacturers, quality-controlled in every lot, and available as white-label ODM/OEM.

Data center corridor with server racks

The Division at a Glance

Electronics is the founding division of TransHarbor Trading Limited and remains the backbone of our daily business. What began as a sourcing desk for electronic components has grown into a full-stack electronics supply operation that covers everything from a single capacitor to a rack-ready white-label server. We serve three distinct but overlapping customer groups: hardware brands and OEMs that need manufacturing capacity without the factory, distributors and trading companies that need reliable fill-in stock, and operators — telecom, internet, data center and security — that deploy networking equipment and servers at scale.

Our model is deliberately simple. We buy from established manufacturers, original factories and authorized channels, hold or coordinate stock, run incoming quality inspection, and ship to your door with complete documentation. Because we are not tied to any single brand, we can source across the market to find the right balance of price, availability and specification for each order. When a customer needs a private-label product, our white-label ODM/OEM program takes a proven hardware platform, customizes the firmware and the user interface, applies your brand, and delivers a finished product that behaves like an in-house design.

Quality control is non-negotiable. Every batch we handle is traceable to its production source, and lots are subject to visual inspection, sample testing and, where required, laboratory analysis. We understand that in electronics the cost of a silent failure is far higher than the price of the component itself, so we invest in the checks that protect your production line and your end customers. Documentation — certificates of conformance, test reports, MSDS, origin certificates and full packing lists — is prepared to the standard your market requires.

Compliance is built into the way we work. Products supplied through the division meet the environmental and safety directives that apply to their destination markets, including RoHS, REACH, CE and FCC where applicable, and we keep current on changes to these regimes so that your shipments do not get held at customs or rejected on arrival. Where a certification is specific to your market or application, we support the process with the technical files, test data and manufacturer declarations you need.

Flexibility is what our customers mention most. We quote sensible minimums instead of factory minimums, combine mixed SKUs into single consolidated shipments, hold buffer stock for repeat programs, and manage lead times honestly — telling you at the order stage what is available now and what must be built to order. Whether you need a small batch for a pilot run or container-level volumes for a production program, the same sourcing discipline applies.

If you are evaluating a new supplier for components, upgrading your network infrastructure, or looking for a manufacturing partner for your own hardware brand, the electronics team at TransHarbor can respond with a specific, documented proposal — not a brochure.

Underpinning every order is a sourcing network that spans the major manufacturing regions and a team that works in the languages and time zones of our customers. When a program grows, we grow with it: buffer stock for repeat orders, consolidated freight that keeps unit costs down, and the documentation discipline that keeps your audits clean. When a program changes, we change too — re-quoting, re-scheduling and re-validating before the old plan costs you money. This is the operating rhythm of a supply partner, not a one-off vendor, and it is the reason why customers who start with a small trial order tend to stay for years.

The same discipline runs across every desk in the company: a clear specification, a documented inspection, a bankable contract and a delivery that matches the promise. That is the standard we hold ourselves to, and it is the standard you can measure us by on the first order and the hundredth.

Assorted electronic components
Product 01

Electronic Components

TransHarbor supplies a broad range of electronic components covering the categories most needed by contract manufacturers, repair networks and trading partners: passive components such as multilayer ceramic capacitors, resistors, inductors and ferrite beads; discrete semiconductors including MOSFETs, diodes and transistors; active devices such as microcontrollers, application processors, memory and logic; plus connectors, relays, crystal oscillators, thermal management parts and fasteners.

Every component order starts with sourcing discipline. We procure through original factory agreements and authorized distribution channels wherever possible, and we verify the identity of stock from secondary sources before it enters our process. Each lot is logged with its date code, batch number and chain of custody so that your production records can be matched to ours. Counterfeit prevention is taken seriously: parts that do not carry clear provenance are either cleared through additional testing or declined entirely.

Incoming inspection follows a practical protocol. Visual checks cover markings, packaging and solderability indicators; sample testing verifies key electrical parameters where the volume warrants it; and special requirements — such as date-code windows, MSL handling or temperature-sensitive storage — are flagged and managed before goods leave our warehouse. We also prepare the documentation set your factory or your customer expects, including certificates of conformance, inspection reports and material declarations.

For volume buyers we offer flexible programs: spot purchases for immediate needs, scheduled releases for ongoing production, and mixed-SKU consolidation that turns a long component list into one manageable shipment. Minimums are kept practical, and long-tail or end-of-life parts can often be secured through our network before they disappear from the market.

Logistics completes the component offer. We hold stock in bonded facilities and can ship by express, air or sea to suit the urgency of your order, with batch-level tracking and delivery documents prepared for your customs requirements. For customers with recurring programs we also manage consumption-based replenishment — reviewing your usage, forecasting the next requirement and staging the stock before your line runs short, rather than reacting after it does.

Product 02

Communication Chips

Communication chips are the heart of modern networking hardware, and this is the category where TransHarbor adds the most value for hardware developers and white-label manufacturers. We source radio-frequency front-end components, baseband processors, Wi-Fi and Bluetooth system-on-chip solutions, Ethernet switch and PHY devices, optical transceivers, and the DSP and timing components used in optical modules — covering the silicon that makes routers, switches, gateways and access points work.

Our role goes beyond simply delivering parts. Because many of our customers build white-label networking equipment, we pair chip supply with the engineering context those chips need: reference designs, antenna and RF layout guidance, driver and SDK availability, and firmware porting support. This is what turns a component sale into a working product program, and it is why hardware teams use us as an extension of their own procurement and engineering staff.

Supply reliability matters as much as technical fit. Communication silicon is subject to allocation and long lead times, so we maintain visibility on manufacturer lead times, build meaningful buffer stock for our recurring programs, and keep alternative sourcing options identified for every critical device. Obsolescence management is part of the service: when a chip approaches end-of-life, we work with you on lifetime buys, compatible replacements or redesign planning before the part becomes hard to find.

Every chip order ships with the technical documentation that keeps your production line compliant — datasheets, packing data, RoHS declarations and, where required, origin documentation. If your team is designing a new platform or keeping an existing one alive, send us your BOM and we will respond with availability, pricing and realistic lead times.

Quality assurance runs through the chip program. Devices are verified against the manufacturer markings and date codes, storage is managed to the ESD and moisture-sensitivity requirements of the components, and any material of uncertain provenance is either cleared through additional testing or rejected before it enters your supply chain. For high-volume programs we can arrange incoming quality inspection at our side, with the reports issued before shipment, so the parts your line receives are the parts your engineers approved.

Networking Equipment

TransHarbor supplies complete networking equipment for service providers, enterprises, campuses and industrial sites: broadband routers, Ethernet switches from access to core density, wireless access points, GPON OLTs and ONUs, firewalls and security appliances, and the small cells and CPE devices used in fixed and mobile access networks. Whether you need a single SKU or a full portfolio, we can supply finished, tested hardware instead of a pile of components.

The white-label route is our signature offer. A customer who wants to launch a network equipment brand does not need to build a factory — we take proven hardware platforms, customize them with your brand, and configure firmware and management interfaces to match your requirements. Open-ecosystem firmware options remove vendor lock-in, so your products can be managed by your own systems and upgraded on your schedule, not a silicon vendor's roadmap.

Performance is verified rather than assumed. Configurations are matched to your use case — port density, PoE budget, throughput, VLAN and routing features, management interfaces — and every unit is factory-tested before release. We also handle the practical details that make deployment smooth: correct power supplies and accessories, professional packaging, and documentation that your installers and end customers can actually use.

Certification and delivery are handled end to end. Where your market requires CE, FCC, RoHS or country-specific approvals, we coordinate the compliance process and provide the declarations and test evidence. Shipping is arranged worldwide by air or sea, with batch tracking from our warehouse to your door, and spare units can be held in buffer for service-critical deployments.

Our support extends beyond the sale. For each platform we maintain the technical documentation — datasheets, firmware release notes, configuration guides and compliance files — and our team can advise on feature selection, SKU rationalization and rollout planning so a product launch stays on schedule. For operators, we can also manage life-cycle planning: when a platform approaches end-of-life, we help you stage the migration to the next generation without leaving deployed sites unsupported.

Servers & Storage

For data center operators, IT resellers and private-label server brands, TransHarbor supplies rack servers and storage systems built to your configuration: 1U and 2U compute platforms, high-density and GPU-accelerated servers for AI and rendering workloads, storage servers, NAS appliances, and JBOD or SAN expansion units. We are not a box shifter — every platform is specified around the workload it will actually run.

Configuration is where the value is created. You define the processor family, memory profile, storage mix, network interfaces, RAID or HBA choices and power redundancy; we translate that into a validated bill of materials and build to your specification. For our ODM customers we also handle the brand layer — chassis markings, BIOS and management firmware customization, serialization and label sets — so the finished unit is unmistakably yours.

Reliability programs come standard. Systems undergo burn-in and memory testing before release, firmware is aligned to a known-good baseline, and each unit ships with a complete configuration record. We keep spare parts visibility for the platforms we sell, and our support desk can walk your technicians through diagnosis during the warranty window rather than leaving you to chase component vendors.

Deployment logistics complete the offer: professional crating for air or sea freight, batch-level tracking, and staging support when a program calls for pre-configuration before the equipment reaches site. Whether your need is a pilot rack, a reseller pipeline or a multi-rack data center rollout, the servers and storage team can quote against your exact configuration list.

Compliance and lifecycle management are handled as standard. Systems are configured and shipped with the environmental and safety declarations your market requires, and we maintain the BIOS, firmware and driver baselines for the platforms we deliver, with the documentation your operations team needs for patching and maintenance. As workloads evolve, we support upgrades — memory, storage, accelerators — so the hardware you bought keeps earning its place in the rack.

Construction Machinery

Mining machinery, large excavators, cranes, loaders, hoisting gear and mining trucks — sourced from established manufacturers, inspected to working standard and delivered site-ready with spare parts support.

Yellow excavators working in an open-pit mine at night

The Division at a Glance

The construction machinery division of TransHarbor Trading Limited supplies the heavy equipment that moves earth, rock and material at mines, quarries, ports and construction sites: mining machinery, large hydraulic excavators, cranes, loaders, hoisting equipment and mining trucks. Our customers are mining operators, civil contractors, rental fleets and trading partners who need equipment that is ready to work when it arrives — not a project they have to finish themselves.

Sourcing runs on a three-tier model. New machines are sourced directly from established manufacturers and their authorized distributors, with full manufacturer documentation and warranty where available. Quality used and reconditioned machines are sourced from operating fleets, inspected and serviced before sale, with the work performed and the condition documented. And for customers who need maximum value for a defined budget, we source well-maintained older equipment that still meets the operational requirement, with the true condition stated honestly in the offer.

Condition is established by inspection, not by photographs. Every machine in our program is checked — engine, hydraulics, undercarriage, attachments, electrical system and structural integrity — and the inspection report, the operating hours and the service history travel with the offer. Where your financing or your management requires it, we arrange independent inspection and valuation reports from recognized firms, so the decision is made on evidence.

Logistics for heavy equipment is a specialist discipline. Machines are dismantled where necessary, secured on low-bed trailers or flat racks, shipped by container, RoRo or breakbulk vessel, and delivered with the export documentation, customs clearance support and, where required, the import paperwork your destination demands. We have moved equipment through the ports and borders that serve mining and construction regions, and we know where the delays hide.

Export compliance is handled as a matter of course: origin documentation, export licensing checks, end-user and end-use screening, and the paperwork that keeps your shipment moving through customs without becoming a legal problem later. We review these before the machine is booked, not after it is stuck at a port.

After-sales support completes the offer. We supply the spare parts that keep the fleet running, maintain the technical documentation for the machines we sell, and answer the operational questions that come up when a machine reaches site. A machine is only as good as the support behind it, and our support does not stop at the port.

Financing and structure are part of the machinery offer as well. Equipment purchases are capital decisions, so we work with the payment and documentation structures that support them — letters of credit, installment schedules, leasing structures where the market uses them — and we prepare the technical file that supports your own financing, insurance and registration processes. For fleets, we can also advise on fleet composition: which machines match the application, which specifications protect resale value, and how to stage a purchase program so the capital is deployed where the production is.

Across every machine and every program, the standard is the same: honest condition reporting, complete documentation and delivery that matches the promise. Buy from the machinery desk and you are not buying a picture and a promise — you are buying an inspected machine, a documented history and a team that stays reachable after the handover.

Mining Machinery

Our mining machinery program covers the equipment that keeps an open-pit or underground operation running: primary and secondary crushers, screening plants, drilling rigs, continuous miners and roadheaders, and the supporting equipment — feeders, conveyors and auxiliary machines — that a site needs to move material from the face to the mill.

We supply new machinery from established manufacturers and quality used or reconditioned units, and we match the machine to the job. A crusher is quoted with its throughput capacity, feed size, product size and power requirements; a drill rig with its hole diameter, depth and mobility; a screening plant with its deck configuration and tonnage. The specification is the contract, and the inspection report documents the condition the machine is actually in.

For operators building or expanding a site, we can assemble the equipment list for a defined stage of the operation — loading, hauling, crushing, screening — and quote the set as a program rather than machine by machine. This reduces both the procurement effort and the risk that one piece of equipment becomes the bottleneck of the whole line.

Spare parts and consumables — wear parts for crushers, drill bits, screen panels, filters and hydraulic components — are part of the service. We maintain the technical documentation for the equipment we sell and can support your site team with the parts that keep production running. Every machine ships with its full documentation set, including the inspection report and the service history.

Application support is part of the sale. Our team advises on the equipment selection, the configuration and the operating parameters for the specific job — the crusher setting that gives the required product, the screen deck that matches the feed, the drill pattern that suits the rock — so the machine you buy is the machine that produces on day one. Where a site is new or expanding, we help with the equipment list, the staging and the documentation that the project financing and the site management both need.

Large Excavators

Large hydraulic excavators are the workhorses of the open-pit mine and the heavy civil site, and our program covers the operating class that moves the real tonnage — machines from the 20-tonne class up through the 50, 80 and 100+ tonne units that load trucks and handle the hardest duty in the pit.

Every excavator is specified by the parameters that decide what it can do: operating weight, engine power, bucket capacity, maximum digging depth and reach, and the undercarriage and arm configuration. We match the machine to the application — loading trucks, digging in hard rock, mass excavation — and offer the attachments that complete the package, including buckets, hydraulic hammers and quick couplers.

Condition is documented, not promised. Each unit is inspected on engine and hydraulics, undercarriage wear, structural condition and hours, with the inspection report included in the offer. Where required we arrange independent inspection, and the machine is serviced and tested before shipment so the first shift at your site is productive, not diagnostic.

Delivery covers the full chain: dismantling where the size requires it, secure transport by low-bed, RoRo or breakbulk, export and destination documentation, and customs support. Spare parts programs — filters, hoses, undercarriage parts, attachments — can be arranged for the machines we sell, so the fleet keeps working after the delivery is signed.

We also help with the commercial structure of an excavator purchase. Equipment is a capital decision, so we work with the payment instruments your market uses — letters of credit, installment programs, leasing structures where they apply — and prepare the technical file that supports your financing, insurance and registration. For fleets, we advise on the composition itself: the operating class that matches the loading and hauling profile, the specification that protects resale value, and the staged purchase plan that deploys capital where the production is.

Cranes, Loaders & Hoisting

This product family covers the lifting and loading equipment that works alongside the big machines: mobile cranes and truck cranes for lifting on site, crawler cranes for the heaviest picks, wheel loaders and skid-steer loaders for loading and material handling, forklifts for the yard, and the hoisting and rigging equipment that supports erection and maintenance work.

Cranes are supplied on their working specifications — rated lifting capacity, boom length, counterweight configuration and mobility — and every unit is checked on the critical systems that decide whether a lift is safe: structure, winches, brakes, hydraulic functions and the safety devices that protect the operator and the load. Documentation includes the load chart and, where available, the original inspection records.

Loaders are the productivity machines of the quarry and the stockpile. We supply wheel loaders in the bucket classes your operation needs — from the compact units that work inside plants to the large loaders that feed crushers and load haul trucks — with the bucket capacity, breakout force and operating weight stated for each machine.

As with the rest of the division, every unit is inspected, serviced and documented before shipment, and we arrange the transport, export paperwork and destination customs support that gets the machine from our yard to your site. Spare parts and attachments — buckets, forks, rigging — can be included in the same program.

Safety and compliance are handled as part of the offer. The machines we supply are checked against the operational requirements of your site — lifting equipment against the load charts and inspection standards that apply, loaders against the operator protection and environmental requirements of the destination — and the documentation that your regulators and insurers expect is prepared with the sale. For operators, this means a machine that arrives with its paperwork in order, ready for commissioning rather than for a compliance project.

Mining Trucks & Vehicles

Mining trucks move the material that the excavators dig, and our program covers the full range of off-highway haul trucks — from the rigid-frame trucks of the 40 to 100+ tonne payload class to the ultra-class units that serve the world's largest mines — plus the construction trucks and support vehicles that keep a site running.

Each truck is offered with the numbers that decide its place in your fleet: payload capacity, engine power, body volume, tire size and condition, and the operating hours and service history. We match the truck to the haul profile — distance, gradient, material density — because a truck that is undersized for the cycle wastes fuel and tires, and one that is oversized wastes capital.

Condition checks cover the systems that carry the load and the cost: frame integrity, suspension, braking system, powertrain, tires and the structural condition of the body. The inspection report travels with the offer, and where the size of the transaction justifies it we arrange independent inspection and valuation from recognized firms.

Logistics for ultra-class equipment is a specialist operation — component dismantling, specialized transport and careful coordination at both ports — and we handle it end to end. Spare parts programs covering tires, filters, brake components and drivetrain parts can be structured for the fleet, and our technical documentation supports your maintenance team from the day the trucks arrive.

Fleet economics are part of the truck program. We help buyers match the haul truck to the actual haul profile — distance, gradient and material density — because that match, more than the purchase price, determines the cost per tonne moved. We also advise on the maintenance plan, the tire program and the spare parts strategy that keep availability high and downtime predictable, so the fleet you build is the fleet you can plan around.
