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

Yes — every batch ships with its own COA, covering the tested parameters and confirming the product meets specification before release.

The COA is issued against the same limits used for QC release, so what you receive is verified — not just sampled. For cosmetic registrations we also provide the MSDS, ingredient declaration and, on request, third-party reports.
