Certified brands

Directory

Every brand holding an HMTc certificate, and every certified product beneath it. A published directory rather than a queryable database — the register is browsable here because these brands chose to be listed, while certificate lookup stays single-record.

The register

No brands certified yet

The register opens with the first certificate issued against a published subcategory standard. Fifteen standards are published and open for application; no brand has completed the three-lot baseline yet. This is an empty register, not a hidden one — when it fills, it fills here.

A specimen entry, shown so the register’s shape is legible before it fills. Listing is a consequence of certification, not a purchasable placement; order and prominence are not for sale.

What a brand page shows

A brand controls how it describes itself. It does not control what the page says about its certificate. That split is the reason the directory is worth reading.

The brand controls
Description and about copy
Logo and product imagery
Website and retailer links
Which certified products to feature
The program controls
Certificate status and dates
Which standard each product was tested against
Analyte panel and native basis
Scope-of-the-mark language

Reading the mark

The mark on a pack means that product was tested at or below every value in the standard named for its subcategory, in that product’s native basis, on the stated analyte panel. It does not mean the product is safe, that the brand’s other products are certified, or that analytes outside the panel were controlled. Scope travels with the mark, and it is stated here rather than left to inference.

A brand appearing in this register with one certified product is not a certified brand. It is a brand with a certified product, and the page says which one.
