Buyer FAQ
Quality-document questions procurement teams ask first.
Can buyers request COA, HPLC, MS, and SDS before ordering?
Yes. Qualified B2B buyers can request available COA, HPLC, MS, SDS, storage notes, and batch-context documents before bulk review or during purchase-list evaluation.
Are all batch documents published publicly?
No. Full batch documents are matched to product, SKU, and order context, then shared with qualified buyers for procurement review when available.
What information helps match the correct quality document?
Send the product name, SKU size, intended quantity, requested document types, destination market, and any procurement record requirements.
Do quality documents replace buyer compliance review?
No. Documents support material and procurement review, but buyers remain responsible for destination-market, institutional, and local compliance checks.
