Do you provide a Certificate of Analysis (COA) for every batch?
Yes — every batch ships with a COA issued by our QC laboratory under ISO-compliant procedures.
What the COA Covers
| Parameter | Verification |
|---|---|
| Appearance & color | Visual inspection against standard |
| Aroma | Organoleptic evaluation by trained panel |
| Melting point | Instrumental measurement (50–62 °C) |
| Solubility | Ethanol / fixed-oil / water behavior |
| Residual solvent | GC analysis below specification |
| Composition profile | GC-MS chromatogram |
| Traceability | Origin, harvest date, picking lot, production batch |
Batch Traceability
The COA links your shipment to a specific production batch, so you can trace the material back to the harvest field. If your QC needs additional parameters — heavy metals, microbial counts or allergen data — tell us in advance and we will include them in the analysis program.
