COA Certificate of Analysis
Certificate of analysis or COA
COA are the final testing numbers for every batch of pigment manufactured.
We track batches on all pigments with the exception of samples. We hold examples of COA for our pigments and these may be distributed as needed as examples. Generally, we request a batch related COA for retail manufacturers who order a minimum of 10 kilos. Please request one at the time of ordering 10 kilos or more.
