Knowledge base

While certification status is not public, Suppliers can share certificates with Brands. Please note that ZDHC Contributor Brands and Friends of ZDHC do not have access to your evaluation, progress, or open recommendations.

As part of one of the upcoming releases, the Supplier to Zero certificates will be visible on the ZDHC Gateway and the DETOX.Live portal, respectively. We will update you on these developments in the ZDHC Gateway newsletter (click here to subscribe).
