Q: What is a COA and why does it matter for CBD vaporizer hardware?
A COA, or Certificate of Analysis, is a lab report that shows what's in a product and whether it meets safety standards. For hardware, it typically covers things like heavy metals, plasticizers, and other contaminants. It matters because it's the only independent proof you have that a product is safe and compliant.
Q: How can I tell if a COA is legitimate?
Check the lab's name and accreditation—look for ISO 17025. Also see if the COA has a unique batch number and a date. If the supplier can't explain the details, that's a red flag.
Q: Do I need a COA for every batch of hardware?
Ideally, yes. If a supplier only shows one COA for all their products, they might be hiding batch variations. Always ask for the COA that matches the product you're about to buy.
