The International Chamber of Commerce (ICC) develops Incoterms, which are a set of standard contract terms that help define the responsibilities of buyers and sellers in international trade. First published by ICC in 1936, Incoterms® rules are a set of eleven three-letter trade terms, reflecting business-to-business practice in contracts for the sale and purchase of goods.
Purpose: Incoterms help clarify the tasks, costs, and risks involved in the delivery of goods. They are recognized by UNCITRAL as the global standard for interpreting the most common terms in foreign trade.
Rules: ICC Incoterms rules help to avoid costly misunderstandings by clarifying the tasks, costs and risks involved in the delivery of goods from sellers to buyers. The most recent version of Incoterms is Incoterms 2020, which entered into force on January 1, 2020.
You can find full details of all the Incoterms and their definitions on the International Chamber of Commerce website https://iccwbo.org/.
