Account access
A gated catalog can help keep the product list away from casual browsing and require account context before ordering.
The account gate should support the research-use boundary without becoming a claim about the product itself.
Intended-use acknowledgement
Checkout copy should make the research-use boundary explicit and consistent with product pages, account pages, and receipt language.
The acknowledgement should not be mixed with consumer-facing benefit copy.
Product page limits
A product page should identify the material and show document availability where a posted COA exists.
It should avoid consumer positioning, use guidance, testimonials, and unsupported testing claims.
COA entry limits
A COA entry should show the posted preview and the fields visible on that document.
If a document is not posted, public copy should not imply that the document has been reviewed.
Keep records
Order records, lot references, and posted COAs should stay together so the document trail can be reconstructed later.
