Global Sourcing & Trade Terminology Reference

This glossary covers every major term you will encounter when working with sourcing agents, managing import/export operations, negotiating with overseas suppliers, or navigating international logistics and trade finance. Definitions are written for B2B practitioners, not academics.

Showing 60 of 60 terms

The fee paid to a sourcing agent for their services, typically calculated as a percentage of the total purchase order value (usually 3–10%) or as a fixed service fee per project.

Why it matters: Understanding how your agent is compensated is essential for transparency. Commission-based agents may have an incentive to select higher-priced suppliers; fee-based agents are more clearly aligned with your interests. Always clarify the commission structure before signing any sourcing agreement — and insist on written disclosure of any supplier rebates or kickbacks.

The transportation of goods by aircraft. Air freight is the fastest mode of international shipping, typically taking 1–5 days door-to-door, but commands a significantly higher cost per kilogram than sea or rail freight.

Practical use: Air freight is most cost-effective for high-value, low-weight goods (electronics, fashion accessories), urgent replenishments, or time-sensitive seasonal products. For most volume B2B imports from China or Southeast Asia, sea freight remains the economical default. A rule of thumb: if your cargo exceeds 200 kg or is low-value per kg, sea freight almost always wins on landed cost.
Freight Shipping Lead Time

A non-negotiable shipping document issued by an airline or freight forwarder for the transport of goods by air. It serves as a receipt, a contract of carriage, and a customs declaration document.

Key difference from B/L: Unlike a Bill of Lading, an AWB is non-negotiable — it cannot be used as a document of title. This means it cannot be endorsed and transferred to a third party as a means of transferring ownership of the goods in transit.

A legally binding document issued by a carrier (shipping line) to a shipper, acknowledging receipt of cargo and specifying the terms and destination of transport. The B/L also serves as a document of title to the goods.

Negotiable vs. Non-negotiable: A negotiable (original) B/L can be endorsed and transferred, giving the holder legal right to claim the goods at the destination. Banks require original B/Ls for Letter of Credit transactions. A telex release or surrender B/L allows the consignee to collect goods without presenting the original, used when buyer and seller have established trust.
Shipping Document Title Document LC

A government-licensed storage facility where imported goods can be stored without payment of customs duties until the goods are formally entered into commerce, re-exported, or otherwise disposed of.

Strategic value for importers: Bonded warehouses allow importers to delay duty payments, inspect and sort goods before committing to import, or re-export without ever paying import duties. With the elimination of de minimis in 2025 and rising tariff rates in 2026, bonded warehouse strategies have become materially more valuable for high-volume importers.

A professional who purchases goods on behalf of an importer, acting as the buyer’s representative in the country of manufacture. Also called a purchasing agent or procurement agent. Synonymous with sourcing agent in most B2B contexts.

Agent vs. Trader distinction: A buying agent represents the buyer’s interests and is paid by the buyer (via commission or fee). A trading company buys goods on its own account and resells them to the buyer, profiting from the margin. This distinction matters significantly for quality control accountability and pricing transparency.

Under CIF, the seller is responsible for the cost of goods, freight charges to the destination port, and a minimum level of marine insurance. Risk transfers to the buyer when the goods are loaded on board at the port of origin — despite the seller paying freight and insurance to the destination.

Common misconception: Many buyers assume that because the seller pays freight and insurance all the way to the destination port, risk also travels with the goods. It does not. Under CIF, risk transfers at origin. This makes CIF problematic for buyers who want the seller to bear risk during transit. For that, use DAP or DDP instead.
Sea & Inland Waterway Incoterms 2020

A tax levied by a government on goods crossing its borders. Import customs duties are typically calculated as a percentage of the goods’ customs value (ad valorem), though specific duties (per unit) and compound duties also exist.

2026 context: U.S. effective tariff rates have risen dramatically, with China-origin goods facing a stacked rate of ~33.9% under Section 301 + Section 122 + Section 232 tariffs as of Q1 2026. HTS code classification, country of origin determination, and Free Trade Agreement eligibility are the three primary levers sourcing agents use to legally minimize customs duty exposure.
Tariff HTS CBP

The country where a product was manufactured, produced, or substantially transformed. Country of origin determines which tariff rates, trade agreements, import quotas, and trade remedy measures apply to a shipment.

Substantial transformation test: In the U.S., origin is determined by whether the goods underwent a “substantial transformation” — a change in name, character, or use — in the claimed country. Simply shipping Chinese goods through Vietnam for repackaging does not change their origin. CBP actively investigates origin transshipment fraud; penalties include seizure, heavy fines, and criminal prosecution.
Tariff Classification Transshipment Risk

Under CFR, the seller pays the cost of goods and freight to the named destination port. Unlike CIF, the seller does not provide marine insurance. Risk transfers to the buyer when goods are loaded at origin.

Buyer’s responsibility: The buyer must arrange and pay for their own marine cargo insurance, as well as all import duties and clearance costs at the destination port.

Under DAP, the seller delivers goods to a named place of destination, ready for unloading. The seller bears all risk and costs of transport to the destination. The buyer is responsible for import customs clearance and duty payment.

When to use DAP: DAP is preferable to CIF when the buyer wants the seller to bear transit risk all the way to the destination — not just pay freight. For B2B imports, DAP is often more transparent than CIF because the buyer can manage their own import clearance and see the actual freight cost.

The maximum obligation term for the seller. Under DDP, the seller bears all costs and risks associated with delivering goods to the named destination, including import duties, taxes, and clearance. The buyer simply takes delivery.

Caution for importers: While DDP sounds ideal, it transfers control of import compliance to the seller. If the seller misdeclares the customs value or HS code, the buyer may face legal liability as the “importer of record.” Many experienced trade lawyers advise against DDP for this reason — consider DAP + using your own customs broker instead.

A systematic pre-qualification process for verifying a supplier’s legal standing, ownership, financial health, certifications, trade history, and compliance record before entering a commercial relationship.

What it includes: Business registration verification, legal representative identity checks, credit assessment, litigation/court record search, sanctions screening, export licence and certification validation, on-site factory inspection, and labor compliance review. In 2026, forced labor due diligence has become a legal compliance requirement for U.S. importers under the Uyghur Forced Labor Prevention Act (UFLPA).

The minimum obligation term for the seller. Under EXW, the seller makes goods available at their premises (factory, warehouse). The buyer bears all costs and risks from that point — including export clearance, freight, insurance, and import duties.

When EXW is problematic: EXW sounds attractive because it appears cheapest, but it places the burden of export clearance on the buyer — who may not be licensed as an exporter in the supplier’s country. In China, a foreign buyer cannot directly export; a licensed Chinese exporter must handle this. Most sourcing agents recommend FCA (Free Carrier) or FOB instead of EXW for China sourcing.

A government document submitted by an exporter providing details of goods being exported — including quantity, value, HS code, and destination. In the U.S., this is known as the Electronic Export Information (EEI) filed via the Automated Export System (AES).

Filing requirement: U.S. EEI filing is required for shipments valued over $2,500 per schedule B number, or for any shipment requiring an export licence. Failure to file is a federal violation. For imports into China, the equivalent is the 报关单 (customs declaration form) filed through the GACC system.

An on-site inspection of a supplier’s manufacturing facility to assess its production capabilities, quality management systems, equipment, workforce, health and safety standards, and compliance with buyer specifications.

Types: Social compliance audits focus on labor conditions and worker rights. Technical/quality audits assess production processes and equipment. C-TPAT audits focus on supply chain security. A full factory audit combines all three. Audits are typically conducted by independent third-party firms such as QIMA, Bureau Veritas, Intertek, or SGS.

Under FCA, the seller delivers goods, cleared for export, to the carrier nominated by the buyer at the seller’s premises or another named place. Risk transfers when the goods are handed to the carrier at the agreed location.

Why FCA is preferred over EXW for China: Unlike EXW, FCA includes export clearance by the seller, making it workable for foreign buyers sourcing from China who cannot act as the exporter of record. Incoterms 2020 updated FCA to allow the buyer to instruct the carrier to issue an on-board Bill of Lading to the seller, resolving a historical issue with LC transactions.

Under FOB, the seller delivers goods on board the vessel nominated by the buyer at the named port of shipment. The seller is responsible for all costs and risks up to and including loading. From that point, the buyer bears all freight, insurance, and onward risk.

The most widely used Incoterm in China sourcing: FOB Shanghai, FOB Shenzhen, and FOB Guangzhou are standard pricing terms in Chinese manufacturer quotes. As the importer, you pay all ocean freight and insurance from the Chinese port. FOB gives you control over your freight forwarder selection — important for cost and tracking visibility.
Sea Freight China Sourcing Incoterms 2020

A logistics specialist who arranges the transportation of goods on behalf of importers or exporters. Freight forwarders negotiate rates with carriers, prepare shipping documentation, arrange customs clearance, and coordinate the entire door-to-door logistics chain.

Forwarder vs. Carrier: A freight forwarder does not own the vessel, aircraft, or truck — they are an intermediary who contracts with carriers on your behalf. A non-vessel-operating common carrier (NVOCC) is a type of freight forwarder that issues its own Bills of Lading and consolidates LCL shipments.

A designated area within the United States (or other country) where foreign and domestic goods can be brought, stored, manipulated, or manufactured free from customs duties until the goods enter domestic commerce.

FTZ advantage in 2026: Under the inverted tariff benefit, goods manufactured in an FTZ using foreign components can pay duty at either the component rate or the finished goods rate — whichever is lower. This has become strategically significant as tariff stacking on Chinese components has increased total import costs.

A 6-digit (internationally standardized) or 8–10 digit (country-specific) numerical code used by customs authorities worldwide to classify traded goods. The HS code determines applicable tariff rates, import quotas, licensing requirements, and trade statistics.

Critical accuracy requirement: Misclassification of HS codes — whether deliberate or accidental — is one of the most common causes of customs penalties for importers. The correct HS code must reflect the good’s actual composition, function, and material. When tariff rates differ significantly across closely related codes (common in electronics and chemicals), professional customs broker classification advice is strongly recommended.
HTS (US) CN Code (EU) Schedule B

A shipping arrangement where a buyer’s goods do not fill an entire ocean container and are consolidated with cargo from other shippers in a shared container. The buyer pays only for the space their goods occupy (typically priced per cubic meter or per weight-measurement ton).

LCL vs FCL: LCL is more economical for shipments under approximately 15 CBM (cubic meters). For larger volumes, FCL (Full Container Load) is typically cheaper per unit. LCL shipments involve additional handling at consolidation (CFS) terminals, which increases transit time and slightly elevates damage risk compared to FCL.

A shipping arrangement where the importer books an entire ocean container — typically a 20-foot (TEU) or 40-foot (FEU) standard container, or a 40-foot high-cube. The importer pays for the full container regardless of whether it is completely filled.

Advantages: Lower per-unit shipping cost for high volumes, reduced handling and damage risk, faster transit (no consolidation delays), and greater security. FCL becomes economically attractive at approximately 15+ CBM of cargo.
TEU 40HQ Ocean Freight

A financial instrument issued by the buyer’s bank guaranteeing payment to the seller, provided the seller presents specific documents (shipping documents, inspection certificates, etc.) that comply exactly with the LC’s terms within the stipulated timeframe.

Why LCs matter in global trade: An LC protects both parties — the seller is guaranteed payment by a bank (not dependent on the buyer’s creditworthiness), and the buyer is guaranteed that payment is only released when compliant documents are presented. LCs are governed by UCP 600 (ICC Uniform Customs and Practice for Documentary Credits). Common in transactions with new or high-risk counterparties, or for high-value orders.
Documentary Credit UCP 600 Bank Guarantee

The total cost of a product from the point of manufacture to the importer’s warehouse or final destination, including the purchase price, freight, insurance, customs duties, customs brokerage fees, port handling charges, and inland delivery costs.

Why unit price alone is misleading: A supplier in China quoting $5.00/unit FOB may produce a higher landed cost than a Vietnamese supplier quoting $5.80/unit FOB if the applicable tariff rate on Chinese goods is significantly higher. In 2026, landed cost modeling must account for tariff uncertainty across multiple scenarios — current rates, potential escalation, and possible trade agreement benefits.

The smallest quantity of a product a manufacturer or supplier is willing to produce or sell in a single order. MOQ is set by the supplier to ensure that the production run is economically viable given setup costs, material minimums, and labor commitments.

Negotiating MOQ: MOQs are often more negotiable than they appear, particularly for buyers who can offer longer-term commitments, pay a premium for small runs, or combine multiple SKUs in a single order. Experienced sourcing agents can often negotiate 30–50% MOQ reductions for new buyers by leveraging their existing supplier relationships and volume commitments across their client portfolio.

A manufacturer that produces goods to another company’s specifications. In global sourcing, “OEM” typically refers to a factory that will produce products branded and specified by the buyer, rather than selling its own branded goods.

OEM vs. ODM: In OEM, the buyer provides the design and the manufacturer produces to spec. In ODM (Original Design Manufacturer), the manufacturer has its own existing design that the buyer purchases and may private-label. OEM requires more involvement in product development but gives the buyer full ownership of the design; ODM is faster and cheaper but limits differentiation.

A quality control inspection conducted when production is 80–100% complete and before goods are packed for shipment. The inspector verifies product conformity, quantity, packaging, labeling, and functionality against the buyer’s approved specifications.

AQL sampling: PSIs use AQL (Acceptable Quality Level) statistical sampling methods to inspect a statistically representative sample of the production batch. AQL 2.5 for critical defects is the most common standard for consumer goods. A PSI report typically provides a clear Pass/Fail recommendation and is the last practical opportunity to intercept quality issues before goods are shipped — and while the supplier still has the leverage of an unpaid balance.

A business model in which a retailer or brand owner contracts a manufacturer to produce goods that are then sold under the retailer’s own brand name, rather than the manufacturer’s brand.

Sourcing agent role in private label: Sourcing agents play a crucial role in private label programs by identifying and qualifying contract manufacturers, managing product development iterations, overseeing quality control, and coordinating compliance labeling. IP protection agreements with the manufacturer are essential in private label sourcing, particularly in China.

A legally binding commercial document issued by a buyer to a seller, specifying the type, quantity, agreed price, payment terms, delivery requirements, and product specifications for the ordered goods.

PO as the master document: In international trade, the PO is the foundational document of the transaction. Every subsequent document — the commercial invoice, packing list, Bill of Lading, LC, and quality inspection report — should reference the PO number. Discrepancies between the PO and shipping documents are a common cause of customs delays and LC document rejection.

A statistical quality sampling standard (ISO 2859-1) defining the maximum defect rate considered acceptable in a production batch. AQL levels specify how many units to sample and how many defects are permissible before the lot should be rejected.

Common AQL levels: AQL 0 (zero tolerance, used for critical safety defects), AQL 1.5 (stringent, for premium consumer goods), AQL 2.5 (standard for most general merchandise), AQL 4.0 (more lenient). Most sourcing professionals specify AQL 0/1.5/2.5 for critical/major/minor defects respectively.

A formal document sent by a buyer to potential suppliers, requesting a price quote for specific goods or services based on defined specifications. The RFQ is the standard starting point for supplier price comparison.

Effective RFQ elements: Product specifications (dimensions, materials, tolerances, finishes), required quantity tiers (e.g., price at 500, 1,000, 5,000 units), required Incoterm (FOB, DAP, etc.), target delivery timeline, packaging requirements, certification requirements, and sample timeline. An incomplete RFQ generates incomparable quotes and wastes both buyer and supplier time.

A professional intermediary hired by an importing company to identify, vet, negotiate with, and manage overseas suppliers on the buyer’s behalf. A sourcing agent acts in the buyer’s interest (unlike a trading company, which acts in its own commercial interest) and is typically compensated through a commission or a fixed service fee.

Core functions: Supplier identification and qualification, price negotiation, sample coordination, production monitoring, quality inspection oversight, export documentation coordination, and logistics liaison. The best sourcing agents combine deep supplier networks, local market fluency, and professional procurement methodology. See best-sourcing-agent.com for verified global sourcing agent directory.

The transportation of goods by ocean vessel. Sea freight is the most economical mode for large-volume international shipments and handles approximately 90% of global trade by volume.

Transit times (typical): China to US West Coast: 14–18 days. China to US East Coast (via Panama Canal): 28–35 days. China to Europe: 25–32 days. Actual transit times vary by carrier, port congestion, and routing. Sea freight rates are denominated in USD per TEU (20-foot container equivalent) and fluctuate significantly based on trade lane demand and carrier capacity.
TEU FCL LCL

The process of independently confirming a supplier’s legal identity, business registration, financial standing, regulatory compliance, and operational capabilities before entering a commercial relationship. Also referred to as supplier due diligence or supplier qualification.

Key verification checks: (1) Business registration against official government registries; (2) Legal representative identity verification; (3) Financial credit scoring; (4) Sanctions and watchlist screening (OFAC, UN, EU); (5) Export licence and certification authenticity; (6) Litigation and court record search; (7) Customs export history analysis; (8) Physical premises confirmation.

An electronic bank-to-bank transfer used to make international payments between buyers and sellers. Also known as a wire transfer. T/T is the most common payment method in B2B global trade due to its speed, relatively low cost, and simplicity.

Standard T/T structures in global sourcing: 30% deposit T/T in advance + 70% T/T against copy of B/L (very common for established relationships); 50% advance + 50% before shipment; 100% T/T in advance (high supplier risk — avoid unless supplier is thoroughly verified); 100% T/T after delivery (high buyer risk — rare for new relationships). Letter of Credit is the alternative that protects both parties without requiring full advance payment.

A company that buys goods from manufacturers and resells them to buyers, typically at a markup. Unlike a sourcing agent, a trading company acts as a principal in the transaction — it buys and sells in its own name, rather than representing the buyer’s interests.

Trading company vs. sourcing agent: Trading companies offer convenience (one point of contact for multiple product categories, export documentation included) but typically offer less price transparency and fewer customization options than direct factory sourcing. A professional sourcing agent can often achieve 15–30% lower landed costs than a trading company by going direct to factory, while providing greater quality control visibility.

The range of financial instruments and products used by importers and exporters to fund international trade transactions and manage the risks associated with cross-border commerce, including payment risk, currency risk, and delivery risk.

Key instruments: Letters of Credit (LC), Documentary Collections (D/C), Bank Guarantees, Supply Chain Finance (buyer-led reverse factoring), Invoice Discounting (seller-led), Export Credit Insurance, and FX Forward contracts for hedging currency exposure. The correct choice of instrument depends on the buyer-seller relationship maturity, transaction size, and country risk profile.

A tax or duty imposed by a government on imported (or occasionally exported) goods. Tariffs are a primary instrument of trade policy, used to generate revenue, protect domestic industries, and influence trade relationships.

Types: Ad valorem tariff (percentage of goods’ value — most common); Specific tariff (fixed amount per unit); Compound tariff (combination of both). In the U.S., tariff rates are set out in the Harmonized Tariff Schedule (HTS) and may be supplemented by additional trade remedy tariffs (Section 301, Section 232) or trade agreement preferences (USMCA, GSP). As of Q1 2026, U.S. tariff policy is in active flux — see our industry intelligence section for current updates.

A document issued by a warehouse operator confirming that specific goods of defined quantity and quality are stored at the warehouse and are available for the holder of the receipt. Can be used as collateral for financing or as a transfer of goods ownership.

Use in trade finance: Warehouse receipts issued by licensed operators can be pledged to banks to obtain inventory financing — particularly useful for commodity traders and importers who hold significant inventory. The warehouse receipt financing market is well-developed for agricultural commodities and metals.
