What heavy-metal and pesticide-residue testing is performed on this oil?
Every batch is tested for lead, cadmium, arsenic and mercury against ChP 2020 limits (Pb ≤5, Cd ≤0.3, As ≤2, Hg ≤0.2 ppm), with pesticide residues screened per ChP 2303 on request.
Heavy Metal & Pesticide Limits
| Analyte | Limit (ChP 2020) |
|---|---|
| Lead (Pb) | ≤5 ppm |
| Cadmium (Cd) | ≤0.3 ppm |
| Arsenic (As) | ≤2 ppm |
| Mercury (Hg) | ≤0.2 ppm |
- The Dao-di Min County sourcing region has low background soil contamination; roots are washed and graded before extraction
- Pesticide-residue screening (organochlorine, organophosphorus, pyrethroid) per ChP 2303 available on request
- CO2-extracted batches carry additional residual-solvent checks per GB/T 5009
- Cosmetic-grade deliveries can be accompanied by a CPSR-ready heavy-metal dossier
Tell us your market's limit table (EU, US, Japan) and we will align the test panel accordingly.
