Incoterms, or International Commercial Terms, are rules created by the International Chamber of Commerce to define the responsibilities of buyers and sellers in international trade. First implemented in 1936 and updated periodically, these terms specify obligations, risk distribution, and cost responsibilities between parties, but do not cover payment terms or contract specifics. The most recent version, Incoterms 2020, organizes terms according to risk and responsibilities, becoming an essential framework in global trade practices.
