Do you provide a Certificate of Analysis (COA) for every batch?
Yes — every single batch of this litsea cubeba oil is released with its own Certificate of Analysis. The COA records the batch number, production date, and the measured values for all release parameters, signed by our quality manager. No COA, no shipment — this is our standing rule for food- and cosmetic-grade oils.
