Four documents, four decisions
Use the TDS during technical screening, the SDS for handling and workplace review, the Specification for quality acceptance, and the COA to verify the supplied batch. A typical value in a TDS is not the same as a release limit, and a release limit is not the same as an actual batch result.
Check consistency across the document set
Product name, code, grade, INCI or chemical identity and supplier name should be consistent. When dates, methods, units or limits conflict, ask the supplier to explain the controlling document before using the information in approval or regulatory work.
Buyer and formulator checklist
- Match product name and code
- Check revision and issue dates
- Separate typical values from limits
- Match COA results to the supplied batch
- Confirm analytical methods and units
