Start here for due diligence
Regulatory and quality teams check whether a certification’s scientific basis is traceable to the literature; legal teams price it as litigation insurance and ask whether it would survive a plaintiff’s expert. HMTc is built for that reading: every published limit traces to a named government maximum or a documented occurrence pool, in the product’s native basis, and the derivation is published rather than self-asserted. This page routes you to the record.
How the limits are set — and traced
- How every limit is derived — the derivation, the five publication gates, and the rationale tag every published value carries.
- Regulation references — the primary-source sovereign instruments a standard adopts when a jurisdiction binds a limit. A record of law, not an HMTc threshold.
- The analyte panel and toxicology basis — for each metal, the government and expert-body record behind its inclusion.
- The standards register — the numeric limits themselves, per subcategory, each in the product’s native basis.
The defensibility record
- The Evidence a Jury Will See — what a certificate, a lab report, and a chain of custody look like under challenge.
- After Palmquist — the litigation context that makes an uncovered metal a liability.
- How HMTc compares — the coverage claim, scoped and dated, so the comparison is defensible rather than promotional.
- Two remediation pathways — what happens when a lot falls short, and the record it leaves.
The citable editions
- Program Manuals — the bound, DOI-bearing edition of each category. The edition named on a certificate is the one that governs it.
