Free tool. A Certificate of Analysis (COA) is the only document that tells you what is actually in a hemp product. Enter the cannabinoid values from any COA below and this tool will interpret them — federal compliance, potency, and whether the product is single-cannabinoid or a blend. For adults 21+.
General information, not legal advice. State law may be stricter than federal law. Always confirm the COA batch number matches your product and that the lab is ISO/IEC 17025 accredited. Adults 21+ only.
What Every COA Should Contain
- Lab name and accreditation — look for ISO/IEC 17025. An unaccredited lab result carries little weight.
- Batch or lot number — it must match the number printed on your product. A COA for a different batch tells you nothing.
- Test date — older reports may not reflect the product in your hand.
- Cannabinoid profile — the table you just entered above.
- Contaminant panels — pesticides, heavy metals, residual solvents, microbials, mycotoxins. Each should show a pass result.
Red Flags
- No COA available at all, or only a photo of a partial page.
- Batch number missing, or not matching the product label.
- No lab name, or a lab that cannot be found online.
- Cannabinoid totals that do not add up, or values reported without units.
- Only a potency panel with no contaminant testing.
