 In the time of trade wars, a certificate of origin showing that the product is not originating in a sanctioned country may also be required for the goods to enter the sanctioning country.Moreover, sometimes the origin of the good itself is an evidence of quality and prestige, so it may be beneficial to obtain one, although it does not help traders gain preferential tariff treatment.A preferential certificate of origin is a document attesting that goods in a particular shipment are of a certain origin under the definitions of a particular bilateral or multilateral free trade agreement.
