QMSR is the U.S. FDA’s updated quality management regulation for medical devices, replacing the long-standing QSR in 21 CFR Part 820. The final rule was published on Feb 2, 2024 and becomes enforceable on Feb 2, 2026. QMSR incorporates by reference ISO 13485:2016 and adds FDA-specific provisions and definitions, harmonizing U.S. expectations with the internationally recognized QMS standard while preserving FDA’s statutory framework.
21 CFR 820 (QMSR)ISO 13485:2016 referenceEffective Feb 2, 2026
What changed from QSR → QMSR
- ISO 13485 incorporation by reference: QMSR adopts ISO 13485:2016 as the baseline for compliance and adds FDA-specific clarifications (e.g., device, labeling definitions).
- New QMSR sections: e.g., §820.7 Incorporation by reference, §820.10 Requirements for a quality management system, §820.35 Control of records (including record retention, accessibility).
- Files & records: QSR’s DHF/DMR/DHR expectations are addressed within ISO 13485’s Medical Device File + QMSR record-control requirements.
- Enforcement timing: FDA will enforce QMSR starting Feb 2, 2026; until then manufacturers must comply with QSR. FDA may review pre-2026 records to assess readiness.
Scope & relationship to ISO 13485
- No automatic ISO updates: QMSR is tied to ISO 13485:2016. Later ISO revisions do not apply unless FDA updates the rule.
- Certification vs compliance: ISO certification is not required by FDA; manufacturers must comply with QMSR (ISO 13485:2016 + FDA additions). FDA will verify during inspections.
- Alignment benefits: One ISO-aligned QMS can satisfy U.S. and many global markets (with jurisdictional add-ons).
Transition timeline (high level)
- Now → Feb 2, 2026: Operate under QSR while executing a documented QMSR/ISO 13485 gap assessment and remediation plan.
- On/after Feb 2, 2026: FDA inspects against QMSR; maintain evidence of conformity to ISO 13485:2016 and QMSR-specific provisions.
Quick checklist to prepare
- Run an ISO 13485:2016-based gap assessment mapped to QMSR clauses.
- Update procedures, forms, records to meet QMSR §820.35 control-of-records and any FDA-specific definitions.
- Confirm risk management (ISO 14971) linkages across design, manufacturing, vigilance, CAPA.
- Ensure supplier controls & special processes meet ISO/QMSR expectations (qualification, monitoring, re-eval).
- Train personnel; update internal audit & management review to QMSR/ISO cadence.
QMSR — FAQs
When does QMSR take effect?
QMSR is enforceable on Feb 2, 2026. Until then, QSR remains applicable; FDA will assess QMSR readiness during inspections as needed.
Do we need ISO 13485 certification?
No. FDA requires compliance with QMSR (which references ISO 13485:2016); third-party ISO certification is optional and not a condition for market access.
Are DHF/DMR/DHR gone?
The concepts remain through ISO’s Medical Device File and QMSR record-control rules; you must still maintain equivalent technical and production records.
Will QMSR auto-update if ISO 13485 changes?
No. QMSR is fixed to ISO 13485:2016. FDA would need to revise the rule to adopt a newer ISO edition.
What should we do now?
Execute a clause-by-clause gap analysis, update SOPs/templates, train teams, align audits/management reviews, and verify supplier controls and records retention meet QMSR/ISO.
