Do you provide a Certificate of Analysis (COA) for each batch?

Yes — a **COA is issued for every production batch** and shipped together with the goods. The COA covers: botanical origin and batch traceability (harvest date, picking lot), appearance, color, aroma, melting point (50–62 °C), acid value, ester value, net oil content, residual solvent, heavy metals, pesticide residues, microbial counts and the GC-MS fingerprint. Simply send us the batch number printed on the container and we will re-supply the full certificate at any time — useful for customs clearance, customer audits and regulatory submission.
