Lab reports (COA) for CBD products

What a COA is

A Certificate of Analysis is an independent laboratory report on one specific batch. It shows the measured cannabinoid content — CBD and THC among them — and the results of the purity checks.

It covers a batch, not a product in general: two batches of the same oil are tested separately.

What we ask producers for

• a report for every batch we take into stock;
• CBD and THC content measured rather than claimed;
• checks for heavy metals, pesticides and residual solvents;
• the name of the laboratory and the date of testing on the document itself.

How to read one

Match the batch number on the report against the one on the packaging — if they differ, the document belongs to different goods.

Look at the THC line: it has to be below the legal limit. Then the CBD line: the measured amount should agree with the label.

Finally check the date. A report from years ago does not describe the batch in your hand.
