How vendors are listed
- Tested by Gold Standard. We have issued the vendor a public certificate, and its public results show, passes and failures. A vendor that answers “Yes” to the vendor-directory question when it orders testing goes live with its first public certificate.
- Listed at its request. The vendor asked to be listed (the WooCommerce plugin or by email) and we reviewed it.
- Independent profile. A vendor we have not tested, compiled from public sources: its own site, its certificates and results reported by others, each linked. We do not score or rank vendors.
Vendors appear in alphabetical order. Any vendor can correct its profile or leave the directory by emailing team@goldstandardanalytics.com; its certificates stay public. A listing is not an endorsement of a product, and a certificate covers only the lot it names.
