Start here if you set an approved-certification list
A retailer that names HMTc on an approved-certification list anchors its private-label and supplier program to a published, checkable standard rather than a process claim. This page routes a category or compliance buyer to what they need to evaluate the mark and verify a supplier’s certificate.
What HMTc adds over the marks you already accept
- Certification comparison — HMTc against NSF/ANSI 173, USP Verified, Clean Label Project and the rest, metal by metal. As of August 2026 it is the only third-party certification covering all eight metals.
- Four metals is no longer enough — the regulatory movement (EU nickel, Codex tin, California hexavalent chromium) turning a four-metal panel into a shrinking floor.
- The Retailer as Anchor — how a retailer’s approved list moves a whole category, and the exposure of anchoring to the wrong standard.
Verifying and monitoring the mark
- Verify a certificate — check a supplier’s lot, certificate, or product code against the public register.
- The certified-brand directory — the published list of brands carrying the mark.
- The Surveillance Protocol — the continuous lot testing and chain of custody behind a certificate, so the seal still means something after the first passing lot.
- The standards a product is held to — the numeric limits, per subcategory, in each product’s native basis.
