Certification

Overview

The Heavy Metal Index is operated by the Institute of Contaminant Standards (ICS), which also operates the Heavy Metal Tested and Certified program at heavymetaltested.com. These properties are maintained as architecturally separate products; this wiki does not mention HMT&C-certified brands, does not endorse specific products, and does not function as justification material for the certification program. Where certification-program references appear in this wiki, they are treated as external commercial instruments, not as content produced by the wiki. The program is described at Heavy Metal Tested & Certified.

For general coverage of certification and standards in the heavy-metals space, including comparative analyses across certification bodies and standards-setting organizations, pages will be developed as the relevant literature is ingested. Internal staff tools may use Index evidence for standards review, but public Index pages do not publish candidate limits, pass/fail cutoffs, or certification approvals.

Regulatory Values And HMTc Standards

FDA’s January 2025 lead action levels for processed foods intended for babies and young children are now indexed at FDA 2025 Lead Action Levels for Processed Food Intended for Babies and Young Children. The phrase “Contains Nonbinding Recommendations” is handled as a regulatory-status and legal-caveat field, not as a reason to discard the guidance. The values are FDA final guidance action levels and enforcement-relevant federal context; they are not HMTc standards, not statutory maximum levels, and not public pass/fail determinations.

For HMTc standards development, this distinction is central. A voluntary certification program can be stricter than FDA guidance where the evidence record supports it, but the Index should always preserve the basis for that choice: exact product matrix, exact analyte species, unit basis, method comparability, source tier, achievability, and public-health rationale. Public wiki pages may show external regulatory context and comparable field findings; they should not publish certification approvals or candidate HMTc thresholds.

Update history

The five most recent substantive edits to this page, classified major (evidence or structure moved), correction (a published value or statement was wrong and has been fixed), or minor (narrative rewritten without changing the underlying evidence). Each description is derived from what the edit did to this page; the linked commit is the authoritative record, routine regeneration passes are excluded, and the full version history lives in git. When DOI minting comes online (see schema docs), each entry below will also link to a version-pinned DataCite DOI.
