B2B buyers often request “all certificates” without defining the product or decision. A better approach is to understand the role of each document and ask for the current version that applies to the quoted item.
Certificate of Analysis (COA)
A COA reports batch results or conformity against stated items. Review the product name, batch, test method or basis, limits, results and approval information.
Technical Data Sheet (TDS)
A TDS summarizes technical identity, characteristics, application or specification guidance. It is not necessarily a batch test report.
Safety Data Sheet (SDS/MSDS)
An SDS supports safe handling, storage and transport communication. It does not establish cosmetic efficacy.
Good Document Control
- Match document name to quoted item
- Check revision or batch
- Resolve inconsistent names or units
- Keep approved copies with purchasing records
- Request updates when the product changes
B2B note: Apply this guidance to the exact commercial specification and destination market. General website content is not a batch document, medical instruction or regulatory approval.
