Buyer review points
Confirm whether the supplier can connect product name, batch number, vial strength and available COA/SDS records. Documentation should be reviewed before wholesale ordering, not after materials arrive.
- Ask for batch-specific COA when available.
- Check that the vial label matches the document.
- Confirm storage and shipping notes for the specific material.
- Keep Research Use Only wording clear in all procurement files.
