FDA QMSR Transition (21 CFR 820 → ISO 13485)
Align your quality system to FDA’s Quality Management System Regulation, effective February 2, 2026.
What It Is
FDA’s Quality Management System Regulation (QMSR) amends 21 CFR Part 820 to incorporate ISO 13485:2016 by reference, harmonizing U.S. quality system requirements with the international standard. It becomes effective February 2, 2026. The QMSR changes terminology (for example, the Device Master Record and Device History Record concepts give way to ISO 13485 documentation structures), adjusts records and management expectations, and aligns FDA inspections with the ISO framework.
When You Need It
You need a QMSR transition if you operate a U.S. quality system built to the old 21 CFR 820 Quality System Regulation. Companies already certified to ISO 13485 are largely aligned but still need to reconcile FDA-specific requirements that QMSR retains; companies on a legacy QSR-only system have more work to do.
What We Do
We run a QMSR gap assessment against your current system, build a transition plan and updated procedures and terminology, reconcile the FDA-specific requirements QMSR keeps (such as certain records and labeling controls), retrain your team, and verify readiness for QMSR-aligned FDA inspections. For ISO 13485-certified clients we focus on the delta; for QSR-only clients we run the full transition.
We Live It, Not Just Advise It
Our own family quality system is making this exact transition, on the same deadline, across manufacturing and sterilization operations that FDA can inspect. We are not interpreting QMSR from the outside — we are implementing it inside an FDA-registered establishment in real time, and bringing that working knowledge directly to your transition.
How AuditIQ Helps
AuditIQ maps your existing QMS against the QMSR and ISO 13485 reference, producing a gap list and a prioritized transition punch list so you focus effort where it actually matters before the February 2026 effective date.

When does the FDA QMSR take effect?
The QMSR becomes effective February 2, 2026. From that date, FDA quality system requirements incorporate ISO 13485:2016 by reference, replacing the prior 21 CFR 820 Quality System Regulation structure.
I am already ISO 13485 certified — do I still need to do anything?
Usually yes, but less. QMSR incorporates ISO 13485 but retains certain FDA-specific requirements (for example around records, labeling, and UDI) and changes how FDA inspects. We reconcile your certified system with those FDA-specific deltas so you are clean on inspection.
What happens to the DMR and DHR?
The QMSR moves away from the specific Device Master Record and Device History Record constructs of the old QSR toward ISO 13485’s medical device file and records structure. We update your terminology, documentation map, and procedures accordingly.
