- ACI / ACID Number (Egypt)
- Egypt's Advance Cargo Information system: the Egyptian importer obtains a 19-digit ACID number in Nafeza before shipment, and it must be printed on the invoice, transport document and other shipping documents.
- Advance Payment (Cash in Advance)
- The buyer pays all or part of the price before the goods are shipped, often as a deposit with the balance due against a copy of the bill of lading; it is the safest term for the seller and the riskiest for the buyer.

- A trader certified by customs as reliable and secure, which can get simpler procedures and fewer checks; many countries recognise each other's programmes.
- AES / EEI (Electronic Export Information)
- The US export declaration, filed in the Automated Export System (AES) when goods under one Schedule B or HTS number are worth over USD 2,500 or need an export licence. AES returns an ITN that goes on the bill of lading or air waybill.
- Air Waybill (AWB)
- The transport document for air cargo, issued by the airline or its agent. It is a receipt and the contract of carriage but not a document of title, so the goods are released to the consignee named on it. A forwarder issues a house AWB (HAWB) under the airline's master AWB (MAWB).

- Under a letter of credit, the applicant is the buyer that asks its bank to open the credit; the beneficiary is the seller that is paid if it presents complying documents.
- Arrival Notice
- A notice from the carrier or forwarder to the consignee or notify party that the cargo is arriving, with the ETA, container details, charges and the steps to get it released.
- Assessable Value
- The customs value used as the base for calculating import duty — often the CIF value, but some countries use a separately determined transaction or customs value.

- Binding Tariff Information (BTI) / Advance Ruling
- A written decision by customs on the tariff classification of a product (or its origin or value) given before import and binding on customs. In the EU it is Binding Tariff Information, valid for 3 years; in the US, CBP issues rulings under 19 CFR Part 177.
- Bonded Warehouse

- Cargo Manifest
- The carrier's list of all consignments loaded on a vessel, aircraft or truck, which customs use for risk checks and to match the declarations.
- Carrier Liability Limit

- CBAM (Carbon Border Adjustment Mechanism)
- The EU charge on the emissions embedded in imported iron and steel, aluminium, cement, fertilisers, hydrogen and electricity; from 2026, importers of 50 tonnes or more a year must be authorised declarants and buy CBAM certificates.
- CBM (Cubic Meter)
- Cubic Meter: the standard unit for measuring the volume a shipment takes up, used to work out container fit and often the shipping cost.

- CISG (UN Sales Convention)
- The UN Convention on Contracts for the International Sale of Goods (Vienna, 1980), which applies automatically to sales of goods between businesses in two different member countries unless the contract excludes it.
- Clean B/L / Claused B/L
- A clean bill of lading carries no clause saying the goods or their packaging were defective when received. A claused (foul) B/L notes damage or shortage, and banks reject it under a letter of credit (UCP 600 Article 27).

- The 11-character ID marked on every container: a three-letter owner code, an equipment category letter, a six-digit serial number and a check digit.
- Container Seal
- A numbered, tamper-evident lock fitted to the container doors after loading; its number is recorded on the B/L and checked on arrival.
- Country of Origin Marking
- The 'Made in' marking on goods or their packaging that some countries, such as the United States, require so the final buyer knows where the goods were made.

- A written authorisation that allows a customs broker or forwarder to make customs declarations on behalf of the importer or exporter.
- Customs Value (Transaction Value)
- The value on which ad valorem duty is charged. Under the WTO Customs Valuation Agreement it is normally the transaction value, the price actually paid or payable with certain additions; each country decides whether freight and insurance to the border are included (CIF basis, as in the EU) or not (FOB basis, as in the US).
- Cut-off (CY, SI and VGM cut-off)
- The latest time to hand something to the carrier for a sailing: the CY cut-off for the loaded container at the terminal, the SI cut-off for the shipping instruction (B/L data) and the VGM cut-off for the container's verified gross mass. Missing one can push the container to the next vessel.
- CY and CFS (Container Yard, Container Freight Station)
- The container yard is where full containers are received and stored at the terminal; the container freight station is where LCL cargo is packed into or unpacked from containers.
- D/P and D/A (Documentary Collection)
- Payment through banks under URC 522: the seller's bank sends the shipping documents to the buyer's bank, which releases them against payment (D/P, documents against payment) or against the buyer's acceptance of a bill of exchange payable later (D/A, documents against acceptance). The banks do not guarantee payment.
- Dangerous Goods (DG)
- Goods that can endanger people, transport or the environment, such as flammable liquids (many perfumes), aerosols, lithium batteries and corrosives. They are identified by UN number and class and must be packed, marked, labelled and declared under the IMDG Code (sea), the IATA Dangerous Goods Regulations (air) or ADR (road in Europe).

- DDP (Delivered Duty Paid)
- Delivered Duty Paid: an Incoterms rule where the seller delivers the goods cleared for import at the named destination, bearing all cost and risk including import duty and tax.
- DDU (Delivered Duty Unpaid)

- De Minimis Value
- The value below which a country lets imports in without duty, and sometimes without tax or a full declaration. Thresholds differ by country and change often; the US suspended its USD 800 de minimis exemption for all countries on 29 August 2025.
- Debit Note and Credit Note
- Documents that adjust an invoice after it is issued: a debit note increases the amount owed and a credit note reduces it, for example after a price correction, a shortage or returned goods.

- The release a carrier or its agent issues at destination so the consignee can collect the cargo, usually after the bill of lading is presented or released and charges are paid.
- Demurrage
- A charge by the shipping line for keeping a full container at the port or terminal beyond the free time allowed, before it is picked up (compare detention).
- Denied Party Screening
- Checking the buyer, consignee, banks and other parties to a sale against government sanctions and restricted-party lists before shipping, for example the US Consolidated Screening List; a possible match calls for more checks, not an automatic refusal.
- Detention
- A charge by the shipping line for keeping its container (empty or full) outside the port beyond the free time allowed, before it is returned (compare demurrage).
- Discrepancy (L/C)
- A mismatch between the presented documents and the terms of the credit, or between the documents themselves, that allows the bank to refuse payment.
- DPU (Delivered at Place Unloaded)
- Incoterms rule: the seller delivers the goods unloaded at the named place of destination; the buyer handles import clearance and pays import duties and taxes.
- Dual-Use Goods
- Goods, software and technology that can serve both civil and military purposes, such as certain chemicals, electronics and machine tools; exporting them can need a licence under national export control lists.
- Dumping / Anti-Dumping Duty
- An extra duty imposed when an imported product is sold below its normal value in a way that harms the domestic industry of the importing country.
- Dunnage
- Material such as wood, airbags or cardboard used to fill gaps and stop cargo moving inside a container. Wooden dunnage in international shipments must meet ISPM 15.

- Duty Drawback
- A refund of import duty paid on goods or materials that are later exported, either unchanged or after processing into another product. Conditions, time limits and proof differ by country.
- ECCN and EAR99
- In US export controls, an Export Control Classification Number (ECCN) places an item on the Commerce Control List; an item subject to the EAR but not on the list is EAR99 and in most cases needs no licence, except for an embargoed destination, a restricted party or a prohibited end use.
- EORI Number
- Economic Operators Registration and Identification number: the ID businesses need for customs declarations in the EU and in the UK, where numbers start with GB or XI. It starts with a country code.
- EPR (Extended Producer Responsibility)
- A system that makes producers pay for collecting and recycling their packaging or products after use; in the EU, sellers register in each country's producer register, through an authorised representative if they are not established there.
- ETA / ETD
- Estimated time of arrival and estimated time of departure of a vessel, flight or truck. They are the carrier's estimates and can change; the on-board date on the bill of lading, not the ETD, shows when the goods were shipped.

- FCA (Free Carrier)
- Free Carrier: an Incoterms rule where the seller delivers the goods, cleared for export, to a carrier or place named by the buyer.
- FDA Prior Notice
- Advance notice to the US FDA of every shipment of food for humans or animals coming into the United States, including samples, filed electronically before arrival; food without adequate prior notice is held at the port of entry.
- FOB (Free on Board)
- Free on Board: an Incoterms rule, used for sea freight only, where the seller's risk and cost transfer once the goods are loaded on board the vessel at the named port.
- Forfaiting and Factoring
- Ways to get paid early by selling export receivables: forfaiting buys a single larger receivable on medium- or long-term credit without recourse, usually backed by a bank-avalised bill of exchange or a letter of credit; factoring is a recurring service for short open-account invoices.
- Free Time
- The number of days a container may stay at the terminal (before demurrage) or with the importer (before detention) without charge, set in the carrier's tariff or the freight contract.
- Free Trade Zone (FTZ)
- An area treated as outside the customs territory for duty purposes, where goods can be stored, processed or assembled without paying import duty until they enter the domestic market. Names and rules vary by country (free zone, foreign-trade zone, special economic zone).
- Freight Forwarder
- An agent who arranges transport, documentation and customs formalities on behalf of a shipper or consignee, without necessarily owning the ships, trucks or aircraft used.
- Freight Prepaid / Freight Collect
- Prepaid means the shipper pays the main freight at origin, as is normal under CFR, CIF, CPT, CIP and the D rules; collect means the consignee pays at destination, as is normal under EXW, FCA, FAS and FOB. The notation on the bill of lading should match the Incoterms rule.
- FTA (Free Trade Agreement)
- Free Trade Agreement: a treaty between countries that reduces or removes import duty on qualifying goods traded between them, subject to meeting the agreement's rules of origin.
- General Average
- A maritime rule under which, when sacrifices are made or costs incurred to save a ship and its cargo, for example after a fire or grounding, every cargo owner pays a share, even if its own goods are undamaged; cargo is released only against security, which cargo insurance usually provides.
- GPSR (General Product Safety Regulation)
- EU Regulation 2023/988, applying since 13 December 2024, which requires an EU-based responsible economic operator and product and contact details for consumer products sold in the EU.
- Gross Weight / Net Weight
- Gross weight is the total weight including packaging; net weight is the weight of the goods alone. Both are shown per carton and in total on most packing lists.
- GSP (Generalized System of Preferences)
- Generalized System of Preferences: a program under which developed countries give reduced or zero tariffs to goods from eligible developing countries, without a full free trade agreement.
- Halal Certificate
- A certificate that a product meets Islamic halal requirements; in Indonesia, food, beverages and cosmetics must be halal certified, imported ones included, with the deadlines for imported food and beverages and for cosmetics moved from October 2026 to October 2028.
- HBL / MBL (House and Master B/L)
- The master bill of lading (MBL) is issued by the shipping line to the forwarder or NVOCC; the house bill of lading (HBL) is issued by the forwarder to the actual shipper. The consignee needs the right one released to collect the cargo.
- HS Code
- Harmonized System code: the standardized product classification code used worldwide to determine import duty, trade statistics and licensing requirements.
- HTS, Schedule B, CN and TARIC
- National extensions of the HS code: the US import (HTS) and export (Schedule B) numbers, and the EU Combined Nomenclature (CN) and TARIC codes.
- ICS2 and ENS (Entry Summary Declaration)
- The EU's pre-arrival safety and security system, in which carriers and other parties file an entry summary declaration (ENS) before goods arrive.
- Importer of Record (IOR)
- The party responsible for the import declaration: making sure the goods comply and paying the duties and taxes. Under DDP the seller acts as importer of record or arranges one; under the other Incoterms rules it is normally the buyer.
- In triplicate (in duplicate, in two copies)
- How many copies of a document are required, most often under a letter of credit: "commercial invoice in triplicate" means three. Under UCP 600 article 17(e), terms such as "in duplicate", "in two fold" or "in two copies" are met by at least one original and the rest as copies, unless the document itself indicates otherwise.
- Incoterms
- A set of standard trade terms (EXW, FOB, CIF, DAP and others) published by the ICC that define who — buyer or seller — handles transport, insurance, risk and customs clearance, and at what point.
- Institute Cargo Clauses (ICC A, B, C)
- Standard marine cargo insurance terms: ICC (A) covers all risks except exclusions, ICC (B) and (C) only named perils; CIF requires at least ICC (C) and CIP ICC (A), for 110% of the price.
- Insurance Certificate
- Evidence that a shipment is insured, usually under an open cargo policy, showing the insured value, the cover (for example Institute Cargo Clauses A) and where claims are payable; the seller provides it under CIF and CIP.
- Inward Processing
- A customs procedure that lets goods be imported without paying duty and import VAT for processing or repair, on condition that the processed products are re-exported.
- IOSS (Import One-Stop Shop)
- The EU VAT scheme for goods sold to consumers in parcels worth up to EUR 150: the seller or marketplace charges EU VAT at checkout and declares it in one monthly return, so the parcel is cleared without collecting import VAT on delivery.
- ISBP (International Standard Banking Practice)
- The ICC's guidance on how banks examine documents under UCP 600; widely followed in letter of credit practice.
- ISF (Importer Security Filing, 10+2)
- The US Customs and Border Protection rule that requires the importer to file data on ocean shipments at least 24 hours before the cargo is loaded on the vessel bound for the US. Late or missing filings can lead to penalties.
- ISO Size and Type Code (22G1, 45G1)
- The 4-character code under ISO 6346 marked on each container: the first character gives the length, the second the height and the last two the type, so 22G1 is a standard 20 ft general purpose container and 45G1 a 40 ft high cube.
- ISPM 15 Mark
- The mark on wood packaging such as pallets and crates showing it was treated by an approved method, such as heat treatment, under the international standard ISPM 15.
- Issuing, Advising and Confirming Bank
- The issuing bank opens the letter of credit, the advising bank passes it to the seller, and a confirming bank adds its own undertaking to pay.
- L/C (Letter of Credit)
- Letter of Credit: a bank's conditional payment guarantee to the seller, released only when the seller presents documents that strictly match what the letter of credit requires.
- Landed Cost
- The total cost of getting goods from the seller to the buyer's door, cleared through customs: goods value, freight and insurance (CIF), plus import duty, tax and handling fees.

- Limited Quantity (LQ)
- Dangerous goods in small inner packagings, such as perfume bottles, that may be shipped under simpler packing, marking and document rules within the limits set by the IMDG Code, the IATA Dangerous Goods Regulations or ADR. The package carries the limited quantity mark.
- Lithium Battery UN Numbers (UN3480, UN3481, UN3090, UN3091)
- The UN numbers for lithium-ion (UN3480, UN3481) and lithium metal (UN3090, UN3091) batteries, shipped on their own or packed with or contained in equipment; each brings strict air and sea rules.

- MFN and Preferential Tariff Rates
- The MFN rate is the standard duty a WTO member applies to imports from other members; a preferential rate is lower, set by a trade agreement or preference scheme, and needs proof of origin.
- MT103 and pacs.008 (Payment Proof)
- The SWIFT message for a customer's cross-border transfer: the MT103 until November 2025, now the ISO 20022 pacs.008. Buyers often send a copy as proof of payment, and its UETR reference lets banks trace the transfer, but only the credit to your account shows the money has arrived.
- Named Place (Incoterms)
- The place written after an Incoterms rule, such as FOB Busan or DAP Lyon warehouse. It fixes where delivery happens or where costs pass to the buyer, so it should be as precise as possible and followed by "Incoterms 2020".
- No Commercial Value (Samples)
- Wording for goods sent free of charge, such as product samples. It means no payment, not zero value: customs still needs a realistic value on the invoice to assess duties and taxes.
- Notify Party
- A party (in addition to the consignee) that the carrier notifies when a shipment arrives, often a customs broker or the buyer's agent.
- NVOCC
- Non-Vessel Operating Common Carrier: a company that issues its own bills of lading and sells ocean transport without operating ships, buying space from shipping lines. In the US, NVOCCs are licensed or registered with the Federal Maritime Commission (FMC).
- Ocean Freight Surcharges (GRI, PSS, LSS)
- Charges added to the base ocean freight rate, such as the general rate increase (GRI), the peak season surcharge (PSS), the low sulphur surcharge (LSS) and the bunker (BAF) and currency (CAF) adjustment factors.
- On Board Notation
- A dated note on a 'received for shipment' bill of lading confirming that the goods were loaded on a named vessel. Under a letter of credit, the on-board date is treated as the date of shipment.
- Open Account
- Payment terms where the seller ships and sends the documents directly to the buyer, who pays at an agreed date after shipment or delivery, for example 30 or 60 days. It is the easiest for the buyer and the riskiest for the seller, so it is often combined with credit insurance.
- OUR, SHA and BEN (Bank Charges)
- Codes on an international transfer that say who pays the bank fees: OUR, the sender pays them all; SHA, each side pays its own bank; BEN, the beneficiary pays them all, so it receives less than was sent.
- Packing List
- A detailed list of a shipment's cartons, contents, quantities, weights and dimensions, used by the carrier, customs and the buyer to check what actually arrived.
- Pallet
- A flat platform, usually of wood or plastic, on which cartons are stacked for forklift handling; common sizes differ by region, such as 1200 x 800 mm in Europe and 48 x 40 in in the United States.
- Per Diem (Container)
- A daily charge for keeping a carrier's container beyond the free time, usually outside the terminal; US rules treat per diem charges as demurrage or detention.

- An official certificate from the exporting country's plant protection organization stating that plants or plant products were inspected and meet the importing country's plant health requirements.
- POL / POD (Port of Loading / Discharge)
- The port where the goods are loaded on the vessel and the port where they are unloaded. Both appear on the bill of lading and are often written with their UN/LOCODE, such as KRPUS for Busan.
- Postponed VAT Accounting
- A scheme that lets a VAT-registered importer declare import VAT on its VAT return instead of paying it to customs at clearance; the United Kingdom, Ireland and several other European countries offer it under different names.
- PPWR (EU Packaging Regulation)
- The EU Packaging and Packaging Waste Regulation (EU) 2025/40, applicable from 12 August 2026, which sets substance limits and conformity, marking, labelling and recycling rules for all packaging placed on the EU market.
- Pre-shipment Inspection (PSI)
- A check of quality, quantity or compliance before the goods leave, usually by an inspection company. Some importing countries require it to issue a certificate of conformity, for example under Kenya's PVoC or Nigeria's SONCAP.
- Preferential Origin
- Origin that meets the rules of a trade agreement or preference scheme, so the goods can pay a lower or zero duty when the importer claims it with the right proof (a certificate or a statement on origin). Non-preferential origin only states the country where the goods were made.
- Proforma Invoice
- A preliminary invoice sent before shipment, used by the buyer to arrange payment or an import licence — not a demand for payment and not used to clear the goods through customs.
- Purchase Order (PO)
- The buyer's written order stating the goods, quantity, price, delivery terms and payment terms; once the seller accepts it, it is the basis of the sale.
- Quotation (Price Offer)
- A seller's price offer listing the goods, prices, Incoterms rule and named place, payment terms, lead time and validity. Once accepted, it often becomes the basis of the proforma invoice.
- Responsible Person (Cosmetics)
- Under EU and UK cosmetics law, the person or company established in the EU (or in the UK for Great Britain) who makes sure each cosmetic product complies, keeps its product information file and notifies it (CPNP in the EU, SCPN in Great Britain). A brand based elsewhere must appoint one.
- Returned Goods Relief
- Relief from import duty for goods that were exported and come back, for example when the buyer rejects them, provided they were not improved abroad and the export can be proved; the UK and EU expect them back within 3 years.
- REX (Registered Exporter System)
- The EU system in which registered exporters certify the origin of their goods themselves with a statement on origin on the invoice; consignments of originating products up to EUR 6,000 need no registration.
- RFQ (Request for Quotation)
- A buyer's request to suppliers for a price offer on stated goods, quantities and terms, so that the quotes can be compared on the same basis.
- Rules of Origin
- The criteria that decide which country a product comes from: wholly obtained, a change in tariff classification (CTC) or a regional value content (RVC) threshold, set by each trade agreement or for non-preferential purposes.
- Schedule B Number
- The 10-digit US export classification number, based on the first 6 digits of the HS code, used to report exports in the Electronic Export Information (EEI).
- SDS (Safety Data Sheet, formerly MSDS)
- The 16-section document that describes a product's hazards, safe handling and transport classification. Forwarders read Section 14 to see whether the product ships as dangerous goods.
- Sea Waybill
- A non-negotiable transport document for sea cargo: the carrier releases the goods to the named consignee without an original being presented. It is fast and suits trusted buyers or prepaid sales, but it is not a document of title, so it cannot be used to hold the goods until payment.
- Section 301 / Section 232 Tariffs
- Extra US import duties imposed under two laws: Section 301 against a country's unfair trade practices and Section 232 on imports that threaten national security, such as steel and aluminium. They are added to the normal HTSUS rate through Chapter 99 codes.
- Shipper
- The party that hands the goods to the carrier and is named as shipper on the transport document; it may be the seller, the buyer's agent or a forwarder.
- Shipping Instruction (SI)
- The instruction the shipper sends to the forwarder or carrier after booking, with the shipper, consignee, notify party, goods description, packages, weights, marks and freight terms. The bill of lading is drawn from it, so errors in the SI become errors on the B/L.
- Shipping Mark
- The text and symbols printed or stencilled on the outside of an export carton — main mark, destination, order number and carton number — used to identify a shipment without opening it.
- Sight L/C and Usance L/C
- Under a sight letter of credit the bank pays when it receives complying documents; under a usance credit, by deferred payment or acceptance, it pays at a set time later, such as 90 days after the bill of lading date.
- SLI (Shipper's Letter of Instruction)
- The exporter's written instructions to its freight forwarder for a shipment: routing, documents, charges and, for US exports, the authority to file the EEI in AES.
- Special Containers (Reefer, Open Top, Flat Rack)
- Containers for cargo that does not suit a standard box: refrigerated (reefer), without a fixed roof (open top) or without side walls (flat rack).
- Standby Letter of Credit (SBLC)
- A letter of credit used as a guarantee: the bank pays only if the applicant fails to pay or perform as agreed.
- Stuffing and Stripping (Container)
- Loading cargo into a container (stuffing) and unloading it (stripping or devanning); the IMO/ILO/UNECE CTU Code gives guidance on safe packing and securing.
- Surrender B/L / Telex Release
- The shipper returns (surrenders) the original bills of lading to the carrier at origin, or none are issued, and the carrier tells its destination office to release the cargo to the consignee without originals. It is quick but removes the seller's control, so it is normally done after payment.
- T/T (Telegraphic Transfer)
- Telegraphic Transfer: a same-day or next-day electronic bank transfer, one of the most common ways international trade payments are settled.
- Tare Weight and Payload
- Tare weight is the weight of the empty container, marked on its door; payload is the most cargo it may carry, its maximum gross mass minus the tare. The VGM includes the tare.
- THC (Terminal Handling Charge)
- What the terminal or shipping line charges for handling containers at the port, at origin (OTHC) and at destination (DTHC). Who pays which part follows the Incoterms rule and the freight contract.
- Transferable and Back-to-Back L/C
- Ways for a trader to pay its own supplier from a buyer's credit: a transferable credit lets the first beneficiary transfer it in whole or in part to a second beneficiary, while a back-to-back credit is a separate new credit opened on the strength of the first.
- Transshipment
- Unloading goods from one vessel or vehicle and reloading them onto another during the journey, for example at a hub port. Letters of credit may allow or prohibit it, and UCP 600 has specific rules on it.
- UCP 600
- Uniform Customs and Practice for Documentary Credits 600: the ICC's rule set that most letters of credit follow, governing how banks examine documents and handle discrepancies.
- UN Number
- A four-digit number, such as UN1266, that identifies a dangerous substance or article in transport and appears on the dangerous goods documents and labels.
- UN/LOCODE
- The United Nations code for trade and transport locations: two letters for the country and three for the place, for example CNSHA for Shanghai or NLRTM for Rotterdam.
- US Customs Bond
- A contract in which a surety guarantees to US Customs and Border Protection that the importer of record will pay duties, taxes and fees and meet its entry obligations; formal entries need one, for a single entry or as a continuous bond.
- VAT / GST
- Value Added Tax / Goods and Services Tax: a consumption tax many countries charge on imports, usually calculated on the CIF value plus duty.
- VGM (Verified Gross Mass)
- The total weight of a packed container (cargo, packing, dunnage and the container's tare weight). Under SOLAS, since 1 July 2016 the shipper must declare it before the container is loaded on a ship.
- Volumetric (Dimensional) Weight
- A weight worked out from a package's size: length × width × height divided by a carrier factor, for example 5,000 cm³ per kg for express couriers or 6,000 cm³ per kg for IATA air cargo. Carriers charge on whichever is higher, the actual or the volumetric weight.
- Weight Certificate
- A document stating the gross and net weight of a shipment, issued by the seller or an independent weigher, and often called for in letters of credit.

Terms can vary by country and contract
These are general, widely used definitions. The exact legal meaning of a term — especially duty, tax and documentation requirements — can differ between countries, and a specific contract or letter of credit can define a term more narrowly than the general trade usage. Always follow the exact wording of your own contract or L/C.

Common questions
Are these official legal definitions?
No — they're plain-language explanations for quick reference. For a legal or contractual definition, refer to the applicable law, your contract, or the official ICC Incoterms 2020 rules and UCP 600 text.
Why isn't my term in the glossary?
This glossary covers the terms most commonly seen on trade documents; it isn't exhaustive. If a term is specific to one country's customs or tax system, check that country's customs authority.
Do Incoterms rules mean the same thing in every country?
Yes — Incoterms rules are an international standard maintained by the ICC and are meant to mean the same thing everywhere they're used, which is exactly why they're useful in international contracts. What can vary by country is how customs values goods, calculates duty, or handles VAT/GST — the Incoterms rule itself doesn't change.
