Do you test for heavy metals and pesticide residues?
Yes — heavy metals and microbial safety are tested on every batch, and pesticide-residue screening is available on request, aligning with ChP 2025 and typical export requirements.
Safety Testing
| Test | Method | Limit / Note |
|---|---|---|
| Total heavy metals | ChP general method 0821 | ≤ 5 mg/kg (ChP 2025 supplement) |
| Pb / As / Cd / Hg (individual) | ICP-MS / ICP-OES | Optional panel per market (EU/US) requirements |
| TAMC (total aerobic microbial count) | ChP 1105 | Within ChP limits |
| TYMC (total yeast & mold count) | ChP 1105 | Within ChP limits |
| E. coli / Salmonella | ChP 1106 | Absent per ChP requirements |
| Pesticide residues | GC-MS/MS multi-residue | Optional, on request for organic/GI-grade lots |
| Residual solvents | GC headspace | n/a for SFE-CO2 grade; verified for ethanol-refined grades |
- Supercritical CO2 extraction inherently avoids solvent residue — the closed-loop CO2 system leaves no organic solvent traces
- The 4.8 ha plantation base and GI-protected sourcing regions follow Good Agricultural Practice for TCM materials (GAP), minimizing pesticide input
- Full test reports accompany the COA; third-party (SGS/CMA) retesting can be arranged at buyer's cost
- EU Regulation (EC) No 396/2005 pesticide MRLs are applied for EU-bound shipments when requested
