How are heavy metals and pesticide residues tested in this litsea cubeba oil?
Heavy metals and pesticide residues are tested by accredited third-party laboratories on every production lot of this litsea cubeba oil, in addition to our in-house screening. Samples are analysed by ICP-MS (heavy metals) and GC-MS/MS (pesticide multi-residue), with limits aligned to food-grade specifications (GB 2762 / GB 29938 for China, EU food and cosmetics directives for export).
Test Scope & Limits
| Item | Method | Typical limit |
|---|---|---|
| Lead (Pb) | ICP-MS | ≤5 mg/kg (food-grade); ≤10 mg/kg (cosmetic) |
| Arsenic (As) | ICP-MS | ≤2 mg/kg |
| Mercury (Hg) | ICP-MS | ≤1 mg/kg |
| Cadmium (Cd) | ICP-MS | ≤1 mg/kg |
| Pesticide residues | GC-MS/MS multi-residue | Per EU / codex MRLs; documented screens |
| Residual safrole | GC-MS | ≤0.1% (kept well below regulatory limits) |
- A third-party report can be issued against your destination market specification — EU, US, Japan or China
- The plant material itself is screened at intake, so contaminated fruit is rejected before distillation
- Annual market-specific renewal testing is carried out so our master spec stays current
