CBD Isolate COA FAQs
What is a CBD Isolate COA?
A Certificate of Analysis (COA) is a report from an independent, third-party lab that measures the cannabinoid content of a sample. Each CBD Isolate COA on this page was issued by an ISO 17025 accredited lab and shows the CBD potency for that sample.
Why do results vary slightly between COAs?
Small differences come from normal variation between production runs, suppliers and lab methods. That is why we publish every COA we have on file, so you can see the full range instead of a single best result.
Do I get a COA with my order?
Yes. The batch COA for your lot ships with every order, and you can request a current batch COA before you buy.
How do I read a COA?
Start with the cannabinoid profile, then check the lab name, test date and accreditation. Our step-by-step guide explains each section of a hemp COA for B2B buyers. How to read a hemp COA
