On this page we have Certificates of Internal Analysis (COIA) and Certificates of Quality Assurance (CQA) — each gives us different information.
The CQA tells us the ingredients, the date of manufacture and attributes (like consistency and color). The COIA gives us the potencies, terpenes, pesticides, solvents and the like.
The COIA is performed on the underlying oil before the final products are made.
