Do you test heavy metals and residual solvents?
Yes. Every lot is heavy-metal screened (Pb, As, Hg, Cd per food-safety / Cosmetic Safety Technical Specification limits) on the COA.
Because extraction uses food-grade solvent, we verify solvent residue with GB 5009.262 (not detected) — this is critical for a concrete, and Top reports it explicitly per lot. For cosmetic/food use we confirm residue is within the target market's limit.
We do not release a lot exceeding heavy-metal or solvent-residue limits. Buyers can request the specific panel and third-party verification.
