When Approved Supplier No Longer Means Controlled Risk

Most medical device manufacturers believe their supplier controls are stable. Suppliers are approved. Quality agreements are signed. Certifications are current. Procedures are documented.

But recent FDA warning letters suggest a subtle shift: supplier controls are increasingly being evaluated as evidence of overall Quality System effectiveness - not just purchasing compliance.

The regulation hasn’t changed.
The scrutiny has.

What FDA Is Looking At

Under 21 CFR 820.50, manufacturers must establish and maintain purchasing controls. That requirement is not new.

What enforcement trends show is deeper evaluation of:

• Whether supplier evaluation criteria are clearly defined
• Whether the type and extent of control is risk-based and justified
• Whether outsourced services affecting quality outputs are formally controlled
• Whether supplier changes trigger reassessment across the QMS

In several warning letters, FDA did not argue that procedures were missing. Instead, the agency questioned whether they were implemented, monitored, and applied retrospectively when gaps were identified.

That distinction matters.

Where Risk Quietly Builds

Supplier-related exposure rarely presents itself as a supplier problem.

It surfaces in:

• Complaint investigations that lack supplier visibility
• CAPAs that correct internal issues but not external contributors
• Risk files that don’t reflect current supplier configurations
• “Temporary” changes that were never formally reassessed

Individually, these may seem manageable. Together, they widen the gap between documented controls and operational reality.

Inspection pressure exposes that gap.

The Bigger Issue: Visibility

In many organizations, supplier risk isn’t a policy failure - it’s a systems issue.

Disconnected ERP and QMS platforms, manual reporting, and siloed data make it difficult to demonstrate real-time oversight when regulators ask.

Supplier controls are no longer just about intent. They’re about proof.
