Do you issue a Certificate of Analysis for every batch?
Yes — every single batch of TPS-RO-011 geranium oil is released with a full Certificate of Analysis (CoA) before shipping. The CoA is traceable to the batch number printed on every drum and jerrican, so you can verify arrival quality against the exact production run.
