Incoterms (English: Incoterms, International commerce terms) are international rules in the form of a dictionary that provide unambiguous interpretations of the most widely used trade terms in foreign trade, primarily regarding franco—the place where responsibility passes from the seller to the buyer. International trade terms are standard terms of international sales contracts that are predetermined in an internationally recognized document.
The rules were first published in 1936 by the International Chamber of Commerce; the first edition is known as "Incoterms-1936." Amendments and additions were made later in 1953, 1967, 1976, 1980, 1990, 2000, 2010, and 2020.
