Updated: Sep 7
FDA is replacing 21 CFR 820 (Quality System Regulation) with the Quality Management System Regulation (QMSR) on February 2, 2026, incorporating ISO 13485:2016 by reference and adding a few FDA-specific clarifications (e.g., definitions, records/labeling expectations). Until then, manufacturers must comply with the current QS regulation while preparing for QMSR alignment. QMSR also incorporates Clause 3 of ISO 9000:2015 and adds FDA-specific clarifications to avoid conflicts with other requirements.
This comprehensive guide provides medical device manufacturers with everything needed to understand current 21 CFR 820 requirements, prepare for the 2026 QMSR transition, and maintain compliance throughout the regulatory transformation.
The Historic QSR to QMSR Transformation
On January 31, 2024, the FDA issued a final rule amending the device current good manufacturing practice (CGMP) requirements of the Quality System (QS) Regulation under 21 CFR 820 to align more closely with the international consensus standard for Quality Management Systems for medical devices used by many other regulatory authorities around the world.
What's Changing and When
Current State (Until February 2, 2026):
21 CFR 820 Quality System Regulation remains in effect
Manufacturers must comply with existing QSR requirements
FDA continues current inspection and enforcement approach
No immediate changes to current compliance obligations
Future State (February 2, 2026 and Beyond):
New Quality Management System Regulation (QMSR) takes effect
ISO 13485:2016 incorporated by reference into US regulations
Harmonized international approach to quality management
Enhanced alignment with global regulatory frameworks
Why This Change Matters: This action will harmonize the FDA's CGMP regulatory framework with that used by other regulatory authorities, promoting consistency in device regulation and providing timelier introduction of safe, effective, high-quality devices for patients.
