Do you test for heavy metals and pesticide residues?
Yes — every batch of this bergamot oil is tested for heavy metals, and pesticide residue testing is available on request (or as a standard test for EU/Japan-destined shipments).
Testing Program
| Test | Typical limits | Method |
|---|---|---|
| Lead (Pb) | ≤2 mg/kg | ICP-MS / AAS |
| Arsenic (As) | ≤2 mg/kg | ICP-MS / AAS |
| Cadmium (Cd) | ≤1 mg/kg | ICP-MS / AAS |
| Mercury (Hg) | ≤1 mg/kg | ICP-MS / AAS |
| Pesticide residues | Per EU 396/2005 / Japan positive list | GC-MS/MS multi-residue |
| Furocoumarins (bergapten) | ≤1 ppm (FCF grade) | HPLC (GB/T 45139-2024) |
- Cold-pressed citrus peel oils can carry pesticide residues, so EU-bound shipments are routinely screened against EU MRLs
- GB/T 45139-2024 (= ISO 7358:2021) HPLC method is used for the quantitative determination of bergapten content
- For the BFCF (bergapten-free) cosmetic grade, bergapten is verified at ≤1 ppm on every batch
- Full third-party testing (SGS, Eurofins) can be arranged at cost for certification purposes
