A Certificate of Origin (CO) is a document declaring that goods in a particular international shipment are of a certain origin. The issuance of Certificate of Origin to products being exported is implemented in compliance with an international agreement. It serves as the basic document in the determination of tariff preference in accordance with trade agreements between and among trading partners and in the generation of country-specific trade statistics. CO can also be used to satisfy the buyers that the products exported are wholly obtained, produced or manufactured in a certain country. Customs offices will use this document to determine whether a duty rate is to be applied to the items being imported based on the country or origin. The certificate of origin must be signed and certified by DCCI. The chamber must have access to the other documents like commercial Invoice, packing list in order to verify that the exporter claims the goods originated in that country
