What is FDA 21 CFR Part 820?
FDA 21 CFR Part 820 sets out the quality system requirements medical device manufacturers, and organizations throughout the device supply chain, must meet to legally distribute devices in the United States. It covers the full device lifecycle, from design and development through production, distribution and post-market activities.
Core requirements include design controls, requiring a structured design and development process with defined inputs, outputs, verification and validation; document and record controls; purchasing controls for suppliers and purchased components; and corrective and preventive action processes for addressing nonconformities.
Historically maintained as a distinct U.S. regulation, Part 820 shares substantial overlap with ISO 13485, and FDA has moved toward harmonizing its requirements more closely with the international standard through the Quality Management System Regulation, or QMSR, framework.
Why is FDA 21 CFR Part 820 important?
Compliance with Part 820 is a legal requirement for marketing medical devices in the United States, making it foundational, non-negotiable infrastructure for any device manufacturer serving this market.
The regulation's design control and risk management requirements reflect the direct connection between medical device quality and patient safety, with FDA inspections specifically evaluating whether these processes are genuinely followed, not just documented.
Because Part 820 closely aligns with ISO 13485, organizations already certified to the international standard often find themselves well-positioned to meet Part 820's requirements, though gaps can still exist depending on the specific regulatory framework in effect.
How does FDA 21 CFR Part 820 work?
Part 820's core requirement areas include:
- Design controls. Follow a structured design and development process with defined inputs and outputs.
- Document controls. Maintain and control documents governing the quality system.
- Purchasing controls. Evaluate and control suppliers and purchased components.
- Production and process controls. Control manufacturing processes affecting device quality.
- CAPA. Investigate and correct nonconformities and prevent recurrence.
- Records. Maintain device history records, device master records and complaint files.

Real-world examples of FDA 21 CFR Part 820
A medical device startup builds its quality system around Part 820 requirements from the outset, establishing design controls before beginning formal product development.
An established manufacturer undergoes an FDA inspection focused on verifying that its CAPA process genuinely investigates root cause rather than only documenting surface-level fixes.
A contract manufacturer serving medical device clients aligns its purchasing controls with Part 820 expectations, ensuring supplier qualification and incoming inspection meet the regulation's requirements.
Regulations and standards related to FDA 21 CFR Part 820
FDA 21 CFR Part 820 has historically operated as the primary quality system regulation for medical devices marketed in the United States, with FDA moving toward greater alignment with ISO 13485 through the newer QMSR framework, which incorporates ISO 13485 by reference while retaining certain FDA-specific requirements.
Organizations should confirm the current regulatory framework in effect for their specific situation, since the transition toward QMSR represents an evolving area of medical device regulation.

Common mistakes with FDA 21 CFR Part 820
Common mistakes include treating design controls as a documentation exercise completed after development rather than a structured process followed throughout, which FDA inspections specifically probe for.
Other problems include assuming ISO 13485 certification alone fully satisfies Part 820 without confirming specific regulatory expectations, particularly during the evolving transition toward the QMSR framework.
