A consumer-chemical standard: household cleaning products are largely unregulated for heavy metals, so limits are the strictest credible government value in the product's total-content basis (China GB 14930.1 for food-contact cleaning; a cosmetic read-across otherwise), with method-and-escalation controls where no sovereign limit exists. Basis is never conflated; no occurrence-derived numbers.
