Do you provide a Certificate of Analysis (COA) for each batch?
Yes — a Certificate of Analysis (COA) is issued for every batch of peppermint oil and travels with the shipment. It documents the measured values against the release specification and carries the batch number, production date, expiry date and the authorised QC signature.
