How do you test for heavy metals and pesticide residues?
Every batch is tested against the Chinese national limits for contaminants and pesticides, with reports issued per batch.
Safety Testing
| Parameter | Test method | Limit basis |
|---|---|---|
| Lead (Pb) | ICP-MS / AAS | GB 2762-2022 (≤ 0.5 mg/kg for fruits) |
| Arsenic (As) | ICP-MS / AAS | GB 2762-2022 |
| Cadmium (Cd) | ICP-MS / AAS | GB 2762-2022 |
| Mercury (Hg) | ICP-MS / AAS | GB 2762-2022 |
| Organochlorine / organophosphorus pesticides | GC-MS / GC-ECD | GB 2763-2021 MRL framework |
| Moisture | Karl Fischer | GB 5009.3 |
| Residual solvent (CO2 grades) | GC | Not detected |
- Northeast GAP bases manage pesticide input from planting, keeping residue levels far below MRLs
- Both ICP-MS heavy-metal panels and GC-MS pesticide-scan panels are attached to the COA
- Additional EU/US pharmacopoeia heavy-metal panels (e.g., USP <232>) can be arranged on request
