The most developed product layers are infant and child foods (HMTc Category 1) and children's personal care (HMTc Category 2). Pages summarize source-backed occurrence evidence, data gaps, and applicable regulation links; they do not rank brands or publish certification limits.
Overview
Product-category pages describe heavy-metal evidence for consumer-facing product categories. Start here when the reader’s question begins with a product type rather than a metal.
