Do you test heavy metals and residual solvents?
Yes. Every lot is heavy-metal screened (Pb, As, Cd, Hg, Cu (GB 2762)) and microbiologically checked (total plate count, coliforms, mould & yeast, pathogens) on the COA. If a solvent route is used, solvent residue is verified per GB 5009.262 (typically non-detect for physical routes). We do not release a lot exceeding heavy-metal, micro or solvent-residue limits. Buyers can request the specific panel and third-party verification.
