How to Read a CBD COA (Certificate of Analysis)

A Certificate of Analysis (COA) is a lab report for a specific product batch. For CBD topicals, it is how brands show what was measured—cannabinoids and, often, safety screens—instead of asking you to take marketing copy on faith.

What a good COA usually includes

  • Batch or lot ID that matches the product you bought
  • Cannabinoid panel (CBD and related compounds)
  • Testing lab name and date
  • Sometimes heavy metals, pesticides, or residual solvent screens

How to use a COA when shopping

  1. Open the COA from the brand’s site (Terra Soothe’s current report is here).
  2. Confirm the product name and potency story match the jar (ours is 500 mg CBD per 30 mL).
  3. Skim cannabinoid results and any pass/fail safety sections.
  4. Prefer brands that keep the COA easy to find from the product page—not buried in a PDF maze.

COA + organic: better together

Lab testing tells you what was measured in a batch. Organic certification speaks to how botanical ingredients are produced. Terra Soothe uses both: USDA Organic botanicals and third-party testing you can download.
