A Certificate of Origin (CO) is an important international trade document attesting that goods in a particular export shipment have been wholly obtained, produced, manufactured or processed in a particular country. It is also a declaration by the exporter. Virtually every country in the world considers the origin of imported goods when determining what duty will be assessed on the goods or, in some cases, whether the goods may be legally imported at all. The 1923 Geneva Convention named Chambers of Commerce the official body to issue, sign and stamp Certificates of Origin worldwide.
