Heavy metal testing is an important part of cosmetic safety and compliance documentation, especially for color cosmetics, mineral powders, mud masks, child-related products, eye and lip products, and formulas using naturally derived ingredients. The purpose is to identify contamination or carry-over risks and support filing, platform listing, buyer audits, or quality control.
Information to Confirm Before Testing
| Item | Review Focus |
|---|---|
| Product category | Confirm skincare, color cosmetic, hair/body wash, eye/lip product, child-related product, or special-use scenario. |
| Raw material source | Review mineral powders, pigments, botanical extracts, fragrance materials, and ingredients that may carry elemental impurities. |
| Sample state | Define finished product, semi-finished product, single raw material, packaging-contact sample, or retained batch. |
| Target market | Match test items and criteria with domestic filing, cross-border sales, platform rules, or buyer standards. |
| Report use | Separate R&D screening, outgoing quality control, filing document, buyer audit, and risk review. |
Report Boundary
A heavy metal test report should match the tested sample, batch, test items, and acceptance criteria. Formula changes, raw-material supplier changes, pigment batch changes, production-equipment changes, or packaging-contact changes may require additional testing.
Green Ark Recommendation
Green Ark (Shenzhen) Certification Co., Ltd. recommends setting a testing strategy for incoming raw materials, formula changes, first mass-production batch, and periodic sampling. For cross-border cosmetic sales, ingredient lists, supplier documents, batch records, and target-market requirements should be prepared in advance.
