Indian Oilseeds and Produce Export Promotion Council

A Certificate of Origin (COO) is an important international trade document attesting that goods in a particular export shipment are wholly obtained, produced, manufactured, or processed in a particular country.
COOs are used to establish the origin of imported goods when determining what duty will be assessed on the goods or, in some cases, whether the goods may be allowed legally imported at all.
Certificates of Origin may be needed to comply with Letters of Credit, foreign Customs requirements, or a buyer’s request.
Generally, there are two major types of COs, namely "Non-Preferential” and "Preferential”.
The "Non-Preferential COO" is also known as an ordinary COO, which certifies that the country of origin of a particular product does not qualify for any preferential treatment.
"Preferential COO" refers to COO, which enables products to enjoy tariff reduction or exemption when they are exported to countries extending these privileges: e.g., GSP, Commonwealth Preference Certificate.
In most countries, chambers of commerce are the key agent in the delivery of certificates.
