What Is a CBD Certificate of Analysis (COA)? How to Read a CBD Lab Report
When shopping for CBD products, you’ve probably seen the terms “third-party tested” or “Certificate of Analysis (COA).” But what do they actually mean, and why are they important?
A COA is one of the best ways to verify the quality and contents of a CBD product. It provides information from an independent laboratory that has tested the product, helping consumers understand what is inside before making a purchase.
In this guide, we’ll explain what a Certificate of Analysis is, how to read one, and why it matters when choosing CBD products.
What Is a Certificate of Analysis?
A Certificate of Analysis (COA) is a document issued by an independent laboratory after testing a CBD product.
The purpose of a COA is to verify that the product matches its label and to provide information about its cannabinoid profile and quality.
Many reputable CBD brands make COAs available for customers to review before purchasing.
Why Is Third-Party Testing Important?
Third-party testing means the product has been analysed by an independent laboratory rather than the manufacturer.
This helps provide greater transparency and gives customers more confidence in the product information.
A recent COA can help verify:
What Information Does a COA Include?
Most CBD lab reports contain several sections.
Cannabinoid Profile
This section shows the cannabinoids detected in the product, including CBD and, where applicable, other naturally occurring cannabinoids.
CBD Concentration
The report should indicate the amount of CBD measured by the laboratory.
THC Information
Where relevant, the COA may show THC levels to demonstrate compliance with applicable regulations.
Batch Number
Many reports include a batch or lot number so the COA can be matched to a specific product.
Testing Date
Check that the report is reasonably current and relates to the product you are buying.
How to Read a CBD Lab Report
When reviewing a COA, look for:
- A clear product name

Taking a few minutes to review this information can help you make a more informed purchase.
Why Should You Check a COA Before Buying?
