Answer Details
A document that serves as an instrument for a preferential tariff is referred to as a certificate of origin. This is a document that certifies the country of origin of a product. The purpose of a certificate of origin is to verify that a product meets the eligibility requirements for a preferential tariff, which is a lower import duty that is applied to goods that originate from certain countries. The certificate of origin is used by customs authorities to determine the eligibility of a product for a preferential tariff and to calculate the applicable duty. In some cases, a certificate of origin is also used to demonstrate compliance with trade agreements, such as free trade agreements, that provide for lower tariffs between participating countries.
