Breakfast cereal — rice-based (puffed rice, rice flakes, crisped rice)
HMTc standard for Breakfast cereal — rice-based (puffed rice, rice flakes, crisped rice) (Grains, Cereals, and Rice Products, category 3). Values are stated in the product’s native basis — as sold — per the locked methodology. The standard publishes per analyte; an analyte renders a firm limit only when it has cleared all five shipping gates.
- Standard version: 2.2 (2026-06-09)
- Methodology: HMTc-10 / P97-clean / P45-dirty (CLAUDE.md Part 19, Governing Principles v2.0)
- Native basis: as sold
- Analyte panel: Pb, tAs, iAs, Cd, tHg, MeHg, Ni, Cr-VI, Sn, Al
- Literature baseline: Heavy Metal Index — breakfast-cereal-rice-based (the independent evidence this standard is applied to; one-way citation)

Analyte scope
This disclosure travels with the mark so a certified product is never silently uncontrolled on an analyte.
- Published (firm limit in force): none yet
- In scope, in development (no firm limit yet): tAs, iAs, Cd
- Out of scope for this subcategory: Pb, tHg, MeHg, Ni, Cr-VI, Sn, Al
Status: in development. No analyte in this subcategory has cleared all five shipping gates yet. This page reports the current evidence state honestly; it is not yet a published standard. See Program Structure for how a subcategory reaches publication.
HMTc standards are living, versioned documents. This page reflects 2.2 (2026-06-09) as of 2026-06-22. Superseded versions remain at stable URLs so prior citations resolve. The threshold-setting methodology is described in Program Structure.
