A Certificate of Origin is a document, required by foreign governments, declaring that goods in a particular international shipment are of a certain origin. Even though the commercial invoice usually includes a statement of origin, some countries require that a separate certificate be completed. Customs offices will use this document to determine whether or not a preferential duty rate applies on the products being imported and whether a shipment may be legally imported during a specific quota period. A Certificate of Origin is a signed statement as to the country of origin of the exported products for a particular shipment (i.e. the country where the product was manufactured or last underwent a substantial change or modification normally involving a shift of at least two chapters in the harmonized code) .

GSP certificate of origin, popularly known as GSP Form A, is required under the Generalized Scheme of Prefereces (GSP) program as a valid proof of origin of goods covered by the specific GSP scheme exported to the donor countries from the beneficiary countries. There are currently 13 national GSP schemes notified to the UNCTAD secretariat. The following countries grant GSP preferential tariff to beneficiary developing countries: Australia, Belarus, Bulgaria, Canada, Estonia, the European Union, Japan, New Zealand, Norway, the Russian Federation, Switzerland, Turkey and USA. The beneficiary countries are responsible for supplying the Form A. The government foreign trade office or the Chamber of Commerce of the beneficiary country normally issues this document that must be properly filled out and signed by the exporter.
