API Supplier Qualification Checklist: 10 Things Buyers Must Verify
Supplier qualification is an important step in API procurement. Buyers should verify more than pricing because the wrong source can create documentation gaps, regulatory delays, logistics issues, or quality-review concerns.
Core supplier checks
- Exact API identity and CAS number confirmation.
- Available pharmacopoeial grade and specification.
- COA, MSDS, TDS, GMP, DMF, CEP, or other document availability.
- Source manufacturer context and production capability.
- MOQ, batch size, lead time, and repeat supply possibility.
- Packaging, storage, shelf life, and transport requirements.
- Destination-country export and import feasibility.
- Commercial terms, incoterms, and payment discussion.
- Response clarity and documentation discipline.
- Post-order coordination and shipment communication.
