Incoterms, established by the International Chamber of Commerce in 1936, are critical in international trade for defining responsibilities, costs, and risks between buyers and sellers when shipping goods. They facilitate efficient global commerce by standardizing terms across various countries, thus reducing uncertainties related to differing interpretations of trade rules. The latest version, Incoterms 2020, includes updates such as the renaming of terms and clarifications around obligations and risks associated with the transportation of goods.
