GMP Certificate: What It Is, Who Needs One, and How to Get It

A GMP certificate is an official document that verifies a manufacturer follows Good Manufacturing Practices — recognized quality and safety standards for the production of pharmaceuticals, food products, cosmetics, medical devices, or dietary supplements. It is issued by an authorized third party based upon the information and attestations provided by the businesses.  

 In California, WTC Northern California issues GMP certificates for manufacturers through its Swiftdox digital platform. 

In the United States, GMP certificates are issued by authorized chambers of commerce and trade organizations. WTC Northern California is an authorized GMP certificate issuer serving U.S.-based manufacturers who need GMP documentation for export. 

ISO 9001 certifies a quality management system at an organizational level — it is not product- or manufacturing-specific.  A GMP certificate verifies that a manufacturer’s facility, processes, and controls meet Good Manufacturing Practices for a specific product type.  Most export markets require a GMP certificate; ISO 9001 alone is not accepted as a substitute for GMP compliance documentation.

GMP certificate validity varies by issuing organization and destination market. Most are issued per shipment or for a specific period (commonly 1–3 years depending on the applicable standard). Some regulatory authorities require fresh GMP documentation for each product registration or import authorization. WTC Northern California can advise on validity requirements for your specific destination.

Many countries require both in order to be able to import a product. The Good Manufacturing Practices certificate proves your manufacturing processes are compliant; the Certificate of Free Sale proves your product is legally sold in the U.S.  The WTC Northern California issues both and can process them together for your shipment.
