If you receive a COA that fails the checks above, stop before you pay. Ask the supplier for a replacement, and if they can't provide one, consider walking away. A single non-compliant batch can cost you more than the order's value in fines and lost reputation.

If you've already received the product, don't put it on the shelf. Isolate it and contact the supplier immediately. If the report shows a safety issue, like high heavy metals, dispose of the product according to your local regulations—don't try to sell it.

Remember, a lab report is only as good as the lab that made it. Trust, but verify. A few minutes of checking can save you a world of hurt later.
