Buyer documentation guide
Peptide quality and documentation
A specification is only useful when it can be matched to the exact material and batch. This hub collects the practical checks for COA, TDS, SDS, purity, stability, labels and shipment documents.
How to compare the specification
| Buyer question | Option A | Option B / action |
|---|---|---|
| COA | Identity, lot, method and result | Review against the supplier specification |
| TDS | Technical properties and handling | Confirm the applicable product and grade |
| SDS | Hazard and safe-handling information | Check revision and language requirements |
| Label | INCI and product identity | Confirm before artwork approval |
Buyer checklist
- Use one internal reference number for quotation, specification and documents.
- Record the document revision and issue date.
- Reject documents where product name, lot or company entity do not match.
- Confirm destination-specific requirements before relying on a generic certificate.
