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.

- The CoA is issued in both Chinese and English, stamped and signed by our QC department
- For regulated markets, the CoA can be accompanied by the SDS, IFRA CoC, and a letter of origin
