Start here for due diligence
Regulatory and quality teams check whether a certification’s scientific basis is traceable to the literature; legal teams ask whether it would survive a plaintiff’s expert. What HMTc provides for that reading is a documented control record: what a company tested, what it found, what it controlled, what it corrected, and how the correction was independently verified. 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.
HMTc is not legal advice, and it does not determine a brand’s reporting, recall, disclosure, or contractual obligations. It provides a documented, independently verified control record. It does not promise a legal outcome.
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 certification record under challenge: what a certificate, a lab report, and a chain of custody look like under challenge.
- After Palmquist: a procedural forum ruling, not a decision on causation, negligence, testing duties, or certification, and why an uncovered metal is still a liability in the environment it describes.
- 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.
