INCOTERMS are international commercial terms developed by the International Chamber of Commerce to provide a set of international rules for the interpretation of the most commonly used trade terms in foreign trade. There are 11 INCOTERMS rules divided into three categories that define the obligations of the seller and buyer and transfer of risks and costs. The categories are E-terms where the seller's only responsibility is to make goods available, F-terms where the seller arranges transport within their country, and C and D-terms where the seller arranges and pays for international transport or delivery.
