Are heavy metals and pesticide residues tested on each batch of this osmanthus absolute?
Yes — every batch is tested for heavy metals and arsenic as mandatory items under GB 1886.265-2016, and pesticide-residue testing is available on request for markets that require it.
Mandatory Limits (GB 1886.265-2016)
| Parameter | Limit | Test method |
|---|---|---|
| Lead (Pb) | ≤ 10 mg/kg | GB 5009.74 |
| Total arsenic (As) | ≤ 3.0 mg/kg | GB 5009.11 / GB 5009.76 |
Additional Testing Available
- Full heavy-metal panel (Pb, As, Cd, Hg) via ICP-MS
- Pesticide multi-residue screening per EU/US market requirements
- Mycotoxin and PAH screening on request
- Flowers are grown in low-agriculture-input regions; material is solvent-extracted, which naturally removes most water-soluble residues
- Third-party testing can be arranged at the buyer's cost with an independent lab of your choice
State your market's residue requirements and we will add the corresponding tests to the batch COA.
