A supplier is an entity that provides goods, components, or services to a company, ensuring the necessary materials or expertise for business operations. Supplier qualification is a systematic process of evaluating, selecting, and approving suppliers to ensure they meet predefined quality, regulatory, operational, and business requirements.

Supplier qualification involves identifying and pre-screening suppliers based on business and regulatory criteria, gathering documentation such as certifications and compliance records, and requesting information to assess capabilities and risks. Further steps include conducting risk assessments, performing on-site audits, reviewing quality systems, approving suppliers, negotiating contracts, onboarding vendors, monitoring performance, and periodically requalifying or deactivating suppliers.

The life sciences industry follows strict guidelines for supplier qualification. Key regulations include FDA 21 CFR Part 820 and ISO 13485 for medical devices, EU GMP, and ICH Q10 guidelines for pharmaceuticals.
