GSI is trained and certified by the ICC World Chambers Federation in the issuance of Certificates of Origin. And as a service to our local exporters, GSI is pleased to now offer certificates for U.S. products. A Certificate of Origin attests to a product’s country of origin and is used by foreign customs offices to determine duties and tariffs. Additionally, particular importers may require a Certificate of Origin with their order. For more details on the program, please visit our Certificate of Origin page.
