Do you test for heavy metals and pesticide residues?

Yes — routine batches are tested for heavy metals (lead, arsenic, mercury, cadmium) and pesticide residues, with results declared on request or on the COA, matching the food-additive and cosmetic safety expectations of your market.

Test Coverage

CategoryTypical limits checked
Heavy metalsPb, As, Hg, Cd per food-additive/cosmetic limits
Pesticide residuesOrganochlorine, organophosphorus, pyrethroid screens
Residual solventsNegative for steam-distilled lots
MethodICP-MS / AAS for metals; GC-MS/MS for pesticides
Raw flowers are grown in the GI region under controlled agricultural practice, and finished oil is re-tested after distillation. Third-party lab reports (SGS-style) can be arranged at cost for the lot you order if your buyer demands an independent certificate.

State whether you need third-party testing on the PO, and we will quote the testing fee and add the report to the shipment documentation.
