Do you provide a Certificate of Analysis (COA) for every batch?
Yes — a full COA is issued for every batch, covering physical properties, chemical composition and contamination checks, and it travels with the shipment documents.
COA Coverage
| Section | Tests Included |
|---|---|
| Physical | Appearance, color, density, refractive index, optical rotation, acid value |
| Chemical | GC-MS composition with key compound percentages |
| Purity | Solubility/miscibility, moisture (≤0.05%) |
| Safety | Heavy metals (Pb ≤1 ppm), microbial count (≤100 CFU/g), residual pesticides |
- Batch number, production date and retest date are printed on every COA for full traceability
- COA is issued as a signed PDF, ready for your customs and quality records
- Third-party testing can be arranged at your cost if your buyer requires it
