COA checklist FAQ
How should I use this checklist?
Open the COA for the product you are evaluating and tick each item it satisfies. The score gives you a quick read on how well-documented the batch is.
What is a good score?
6–7 is strong documentation. 4–5 is adequate but worth asking the supplier for what is missing. 0–3 means the paperwork is thin — be cautious.
Is a high score a guarantee of quality?
No. A COA documents a batch; it is one signal among several. Independent third-party testing and a supplier that ties each product to its own batch COA matter most. This tool is educational only.
