What a Certificate of Analysis Actually Tells You

If you have ever bought a botanical product and wondered whether the label matches what is inside the package, the Certificate of Analysis (usually shortened to COA) is the document designed to answer that question. It is a lab report, tied to a specific batch, produced by a laboratory that is separate from the seller.

This guide walks through the parts of a typical COA so you can read one with confidence the next time a vendor offers it.

Start with the batch number

Every COA should identify the exact batch or lot it tested. That number is the link between the document in your hand and the product on your shelf. If a report does not name a batch, or if the vendor cannot tell you which batch your order came from, the report may describe a different product than the one you bought. Keep your packaging until you have matched the two.

The test panel

Most third-party panels for botanical powders cover three broad areas:

Each result is usually listed next to a limit or specification, with a pass or fail marker. A clean report shows every line within its limit.

The laboratory section

The report should name the laboratory and, in many cases, list its accreditations. An independent lab is one with no financial relationship to the seller; that separation is what makes the report meaningful. If the accreditation is unclear, you can usually look the laboratory up directly.

What a COA does not tell you

A COA is a snapshot of one batch, not a promise. It does not establish that a product is risk-free, that it will produce any particular effect, or that it is appropriate for your situation. It also does not automatically apply to other batches, which is why matching the batch number matters.

How we handle reports

We obtain third-party lab testing for our products and provide the COA for your batch when you request it. Email us with your product name and batch number and we will send the matching report.
