This document certifies the country of origin of goods being exported or imported. It is used when trading between countries that are not part of a free trade zone to determine tariffs and eligibility for preferential trade agreements. The certificate of origin is issued by chambers of commerce or other official institutions in the exporting country and presented to customs officials in the importing country. It must match the descriptions of goods provided in the commercial invoice and packing list. Certificates can be issued in multiple languages to accommodate international trade.
