How do you test for heavy metals and pesticide residues?
Every batch is tested for heavy metals, pesticide residues and microbial contamination before release, with results stated on the COA.
Safety Test Limits
| Parameter | Limit | Method |
|---|---|---|
| Lead (Pb) | ≤1 ppm | GB 5009.11 / ICP-MS |
| Other heavy metals | Market-spec based | ICP-MS / AAS |
| Pesticide residues | Verified against EU/US limits on request | GC-MS/MS |
| Total microbial count | ≤100 CFU/g | GB/T / USP methods |
| Moisture | ≤0.05% | Karl Fischer |
- Bitter orange blossoms are a food-crop raw material; harvest is screened and the oil is distilled, which further reduces residue levels
- Certificates from third-party labs (SGS, Eurofins or equivalent) can be arranged per your destination market
Provide your destination market and target limits, and we will lock the exact test panel into the quality agreement and COA template.
