How to evaluate a pharmaceutical ingredient supplier

Supplier qualification is a documented risk-based process. It begins with legal identity and scope, then examines product-specific evidence, quality systems, change control, complaint handling, traceability, and regulatory relevance.

The level of review should reflect the material, intended application, destination market, supply-chain complexity, and evidence available. Corporate registration alone does not prove manufacturing capability or product compliance.

A robust sourcing decision records what was verified, what remains uncertain, who approved the decision, and when the evidence must be reviewed again.
