A certificate of analysis (COA) is a laboratory document that reports what is actually inside a product. This page explains each field so you can verify any product yourself.
The fields that matter
- Batch / lot number — must match the number printed on your product. A COA for a different batch does not verify your unit.
- Laboratory name and accreditation — the lab must be independent from the manufacturer.
- Cannabinoid profile — the measured content of CBD, THC and minor cannabinoids, usually in mg/g and as a percentage. Compare the measured CBD against the label claim.
- THC result — the value that determines country-level compliance. Thresholds differ across Europe, which is why every product on this platform carries a country-eligibility flag.
- Contaminant panels — heavy metals, pesticides, residual solvents and microbial results, each with a pass/fail against the lab’s limits.
- Test date — recent is better; we require current certificates for every live batch.
If any of these fields is missing from a COA, treat that as a signal to ask questions — on this platform, it means the product does not get listed.
