Incoterms (International Commercial Terms) are a set of standardized three-letter trade terms published by the International Chamber of Commerce (ICC) that define the division of costs, risks, and responsibilities between buyers and sellers in international trade contracts. First published in 1936 and most recently updated in 2020 (Incoterms 2020), these terms specify exactly where the seller's obligation ends and the buyer's obligation begins — defining who arranges transport, who pays for freight and insurance, and at what point risk transfers from seller to buyer. Choosing the right Incoterm dramatically affects the landed cost calculation and cash flow for both parties. Under DDP (Delivered Duty Paid), the seller handles everything including import customs clearance and delivery to the buyer's premises — the buyer simply pays the invoice price and receives the goods. Under EXW (Ex Works), the buyer is responsible for everything from the moment goods are loaded at the seller's factory — a significant responsibility for buyers without international logistics expertise. Between these extremes are 11 other Incoterms 2020 terms suited to different trade scenarios. The most commercially significant Incoterms for ocean and air freight are FOB (Free On Board), CIF (Cost Insurance Freight), and DAP (Delivered at Place). FOB is the most commonly used term in international manufacturing sourcing — the seller delivers goods over the ship's rail at the named port, and from that point the buyer bears cost and risk. CIF adds freight and insurance to the seller's responsibility to the destination port. DAP transfers goods delivered but not cleared through customs at the destination. Incoterms affect more than just logistics responsibility — they affect customs valuation (the dutiable value is different under CIF vs. FOB), who controls the freight (and therefore who benefits from volume discounts), and who bears the risk of in-transit loss or damage.
Incoterms Cost Allocation by Term: EXW (Ex Works): Buyer pays ALL costs from factory door FCA (Free Carrier): Seller delivers to carrier; buyer pays freight FOB (Free On Board): Seller to origin port; buyer pays ocean freight CFR (Cost & Freight): Seller pays freight; buyer bears risk from loading CIF (Cost Insurance Freight): Seller pays freight + insurance DAP (Delivered at Place): Seller delivers to named destination DDP (Delivered Duty Paid): Seller pays all including import duty Landed Cost Impact by Incoterm (example: $10,000 goods, $800 freight, $54 insurance, 5% duty on CIF): FOB Invoice: $10,000 → Buyer adds: $800 freight + $54 ins + $545 duty = $11,399 landed CIF Invoice: $10,854 → Buyer adds: $545 duty = $11,399 landed (same total, different invoice) DAP Invoice: ~$11,399 → Buyer adds: $545 duty = $11,944 (buyer adds duty + clearance) DDP Invoice: ~$11,944 → No additional buyer costs (all-inclusive)
- 1Identify which Incoterms 2020 term is specified in the purchase order or contract — confirm both buyer and seller understand the named place (port, terminal, or address) that completes the Incoterm.
- 2Determine which party (buyer or seller) is responsible for each cost element: origin inland freight, export clearance, loading at origin, ocean/air freight, cargo insurance, destination port handling, import customs clearance, import duty and taxes, and inland delivery to final destination.
- 3Calculate the buyer's costs under the chosen Incoterm: starting from the invoice price, add all cost elements that fall under buyer responsibility.
- 4Compare buyer's total cost across Incoterm options — sometimes a higher DDP price is actually cheaper than FOB if the seller can consolidate freight more efficiently or has lower import duty exposure.
- 5Consider who controls the freight booking — under FOB, the buyer controls freight and can negotiate rates directly; under CIF or DDP, the seller controls freight and the buyer loses visibility into freight costs and carrier selection.
- 6Assess risk transfer point — under FOB, the buyer bears risk once goods are loaded at origin; under DAP or DDP, the seller bears transit risk throughout. For high-value goods or unreliable trade lanes, the risk allocation may be more important than the cost allocation.
- 7Document the agreed Incoterm in the purchase order with the specific named place (e.g., 'FOB Shanghai' or 'DDP Chicago warehouse') — an Incoterm without a named place is legally incomplete.
At first glance FOB looks cheaper. But the seller's DDP quote reflects their freight volume discounts and duty optimization. When all buyer costs are summed, DDP can be the better deal — always compare total cost, not just invoice price.
CIF shifts risk and freight cost to seller, but the buyer pays duty on the higher CIF value rather than FOB. For high-duty-rate products, this can meaningfully increase duty expense. Most countries use CIF as the duty basis; the US uses transaction value (FOB equivalent).
DDP includes duty in the seller's invoice. If the seller has better duty management (bonded warehouse, FTZ, first-sale valuation), their DDP price may be lower than the buyer's total under DAP or FOB — particularly for complex imports.
Under CIF, the seller buys 'minimum cover' insurance (Institute Cargo Clause C) by default — which excludes many common causes of loss. Buyers shipping high-value goods should negotiate FOB and purchase their own comprehensive ICC A coverage.
Importers use Incoterm selection to control freight costs and carrier relationships — choosing FOB when they have negotiated volume discounts with freight forwarders, and accepting CIF or DDP when the seller's logistics capability is clearly superior.
Customs brokers advise clients on how Incoterm choice affects customs valuation — particularly the difference between FOB-based US customs values and CIF-based customs values in EU, UK, India, and most other markets.
Letters of credit professionals specify compatible Incoterms in L/C applications to ensure shipping documents can be properly presented — avoiding discrepancies that cause payment delays.
International procurement managers standardize Incoterms in their supplier agreements to create consistent landed cost visibility and reduce invoice reconciliation complexity across global supply chains.
Letters of Credit (L/C) and Incoterms interaction: Banks financing
Letters of Credit (L/C) and Incoterms interaction: Banks financing international trade via letters of credit require specific shipping documents (bill of lading, insurance certificate, commercial invoice) that must match the Incoterm. FCA with a requested on-board B/L is the most L/C-compatible term for containerized freight following Incoterms 2020 changes. FOB under L/C requires careful documentation to prove loading at origin port, while DDP is incompatible with most L/C structures because the seller controls all documents including import customs clearance.
Incoterms do not cover all aspects of international trade contracts — they
Incoterms do not cover all aspects of international trade contracts — they address delivery, transfer of risk, and cost allocation only. Incoterms do not cover: payment terms (open account, L/C, documentary collection), title transfer (separate legal concept from risk transfer), force majeure, dispute resolution jurisdiction, or customs valuation methodology. A complete international trade contract must address these topics separately alongside the Incoterm.
Customs valuation and Incoterms: Most countries (excluding the US) use CIF
Customs valuation and Incoterms: Most countries (excluding the US) use CIF value as the basis for import duty calculation. This means that under FOB, the buyer adds freight and insurance to calculate the CIF dutiable value — paying duty on a figure that includes costs not in the seller's invoice. Under DDP, the seller handles duty calculation based on the goods' commercial invoice value. Misunderstanding the relationship between Incoterms and customs valuation is a common source of duty calculation errors.

What is the most commonly used Incoterm?
FOB (Free On Board) is the most widely used Incoterm globally, particularly for ocean freight between Asia and Western markets. It is the default Incoterm in many manufacturing contracts — the seller delivers to the origin port and loads the goods; the buyer arranges and pays for ocean freight, insurance, destination handling, and import clearance. FOB gives buyers control over freight carrier selection and visibility into freight costs while keeping seller responsibility clear.
What is the difference between FOB and CIF?
Under FOB, the seller's obligation ends when goods are loaded at the origin port — the buyer pays and arranges ocean freight and insurance separately. Under CIF, the seller pays for Cost, Insurance, and Freight to the destination port — delivering a higher invoice price that includes these costs. CIF is convenient for buyers without freight expertise but removes buyer control over carrier selection and insurance coverage quality. Note: CIF is only appropriate for ocean freight — for air or multimodal, FCA and CIP are the equivalent terms.
What does DDP mean in international trade?
DDP (Delivered Duty Paid) represents the maximum obligation for the seller — the seller is responsible for all costs and risks from origin factory to the buyer's named destination, including export clearance, international freight, import customs clearance, import duties and taxes, and inland delivery. From the buyer's perspective, the invoice price is the complete landed cost with no additional import expenses. DDP is the most convenient Incoterm for buyers but requires sellers to have strong local customs and logistics capabilities in the destination country.
When should I use EXW vs. FOB?
EXW (Ex Works) and FOB are both departure terms that favor seller simplicity — the seller's obligation ends at the point of departure. EXW is even more seller-favorable: the buyer must collect goods from the seller's premises and handle all export formalities, including export customs clearance. FOB is more buyer-practical because the seller handles origin inland transport and export clearance. In practice, EXW is rarely used in international trade because buyers cannot handle export formalities from a foreign country. FOB is almost always preferable to EXW for international transactions.
Are Incoterms legally binding?
Incoterms are incorporated into international trade contracts by reference — they become legally binding when both parties agree to use them in the purchase order, pro forma invoice, or commercial contract. The ICC publishes the official Incoterms 2020 rules which define each term's obligations. When incorporated by reference (e.g., 'FOB Shanghai Incoterms 2020'), both parties are bound by the ICC's definitions. Courts and arbitration tribunals recognize Incoterms as the standard for resolving trade disputes about cost and risk allocation.
What is the difference between Incoterms 2010 and Incoterms 2020?
Incoterms 2020 (the current version) made several important changes from Incoterms 2010: FCA now allows for an on-board bill of lading to be requested by the buyer, solving a common letter of credit documentation problem; DDP has been renamed to emphasize that it requires the seller to handle import duties; the insurance coverage level under CIP was upgraded to Institute Cargo Clause A (comprehensive) from Clause C (minimum), while CIF remains at minimum Clause C; and DAT (Delivered at Terminal) was renamed to DPU (Delivered at Place Unloaded). When referencing Incoterms, always specify the year (Incoterms 2020) to avoid ambiguity.
Which Incoterm is best for sea freight containers?
For containerized ocean freight, the ICC recommends using FCA (for buyer-controlled freight) or CIP/CFR/CIF (for seller-controlled freight) rather than FOB or EXW. The reason: in containerized shipping, goods pass into carrier control at the container freight station (CFS) or terminal, not when loaded 'over the ship's rail' as FOB's original definition implies. Despite this technical imprecision, FOB remains overwhelmingly the most used term for containerized ocean freight in practice, and most courts interpret FOB in container shipping as meaning goods are in the carrier's custody at the terminal gate.

For high-value imports, request FOB pricing even if you'd prefer the convenience of CIF — this gives you control over carrier selection (choose your known, trusted carrier), insurance quality (upgrade to Institute Cargo Clause A rather than the minimum CIC Clause C that sellers typically provide under CIF), and freight rate visibility. The 5–15 minutes of extra freight booking work is usually worth the control.
คุณรู้ไหม?
Incoterms are among the most widely used private standardization instruments in international law — the ICC estimates that over $2 trillion of international trade annually is transacted using Incoterms references. Despite this scale, Incoterms have no binding legal force on their own; they only become legally enforceable when incorporated by reference into a contract. The ICC has published Incoterms in 31 languages, reflecting their global adoption across every major trading region.
