What is a COA?

And why is it so important?
A Certificate of Analysis (COA) is one of the most important documents for any hemp product because it proves safety, quality, and legal compliance. A COA is issued by an independent, third-party laboratory and verifies the product’s cannabinoid profile, confirming that THC levels are below the legal limit of 0.3%. It also ensures the product is free from harmful contaminants like pesticides, heavy metals, mold, and solvents. By providing a COA, brands demonstrate transparency and build consumer trust—showing that what’s on the label matches what’s in the product. Simply put, a COA guarantees that your hemp product is clean, compliant, and exactly as advertised.
