A Free Sales Certificate, also known as a Certificate of Free Sale, is a document issued by a government authority that certifies that a product is legally sold in the issuing country and meets all applicable regulations and standards. The certificate is typically required for products being exported to other countries, where the importing authorities use it to verify that the product meets their requirements for safety, quality, and other criteria. The Free Sales Certificate provides assurance to the importing country that the product has been approved for sale in the country of origin and is considered safe for use. The certificate is commonly used for products such as food, pharmaceuticals, medical devices, cosmetics, and chemicals.
