Overview
This page is a scaffolded entry for HMTc Taxonomy v2.0 Category 23 (Food-Contact Consumer Goods and Kitchenware), Row 1: Cans/lids. Studies for this row are still being read. Where a section is empty, the row has not yet accumulated contributing sources of the required kind.
Literature scope
The Heavy Metal Index source corpus is currently focused on food and food-contact materials. This page documents an HMTc Taxonomy v2.0 row in the category Food-Contact Consumer Goods and Kitchenware for which no peer-reviewed primary or government sources have yet been ingested. The page exists as the routing destination for future ingest. Until sources land, the literature-evidence sections below are deliberately empty rather than guessed; HMTc certification thresholds for products in this row continue to be developed under the certification program at heavymetalcertified.com, not on this public page.
Reading guide
Legal, regulatory and retailer teams can use the cited measurements, applicable limits and study limitations to assess the evidence for this category.
Quality teams can examine product form, measurement basis and sources of variation. Journalists and researchers can follow each reference to the original findings and methods.

How standards math uses this page
HMT&C certification thresholds for this row are developed under the certification program at heavymetalcertified.com, not on this page. The row-standard for this row is an aggregate computed from the contributing source pool in the row’s native finished-product basis; it is not a per-source decoration of any single value cited on this page. This public page reports literature evidence only.
Historical recalls and enforcement
Public regulatory events for this row, such as recalls and import alerts, will be listed here as they are catalogued.
Methodology
This page reports what the cited sources say about heavy-metal concentrations in cans/lids. Speciation is non-substitutable (iAs vs tAs, MeHg vs tHg, Cr-VI vs total Cr). Basis is preserved (finished-product as sold unless the source specifies otherwise; see each row for the basis label). Non-detect handling follows each source’s reporting convention. Pooling is avoided across LOD/LOQ, period, geography, and analytical-basis differences. HMT&C certification thresholds for products in this row are developed under the certification program at heavymetalcertified.com, not on this page; this public page reports literature evidence only.
The applicable regulatory jurisdictions for this row are: FDA (food-contact substances), EU (food-contact material regulations), California Prop 65.
