FDA QMSR
The regulation that ended the 21 CFR Part 820 Quality System Regulation era.
The Quality Management System Regulation amends 21 CFR Part 820 by incorporating ISO 13485:2016 by reference — and it changed how FDA inspects device manufacturers on the same day it took effect.
What the FDA QMSR is
The Quality Management System Regulation (QMSR) is the FDA final rule that amends 21 CFR Part 820, replacing the requirements of the 1996 Quality System Regulation (QSR) by incorporating ISO 13485:2016 by reference — with FDA-specific additions layered on top. It was published in the Federal Register on February 2, 2024 and took effect on February 2, 2026, after a two-year transition.
The FDA-specific additions are the parts ISO 13485 does not cover to FDA's satisfaction: control of records (21 CFR 820.35), including signature and date expectations and records-related obligations such as those tied to complaint handling and servicing, and control of labeling and packaging (21 CFR 820.45). Definitions in 820.3 reconcile FDA's vocabulary (per the FD&C Act) with ISO 13485's.
The QMSR applies to manufacturers of finished medical devices marketed in the United States, regardless of where they are located. Combination products continue to follow 21 CFR Part 4.
QMSR versus ISO 13485 certification
The QMSR incorporates the ISO 13485:2016 text — but FDA neither requires nor accepts ISO 13485 certification as evidence of compliance. FDA still inspects directly, against the QMSR. Certification and compliance remain two different things.
Why the QMSR is more than a renumbering
The QMSR is the first structural overhaul of FDA's device quality system requirements since 1996, and it landed together with a second change that affects daily life more than the rule text: FDA retired QSIT — the Quality System Inspection Technique used since 1999 — and began inspecting under compliance program CP 7382.850, Inspection of Medical Device Manufacturers, on the same effective date.
The new inspection approach is risk-based: it organizes QMSR requirements into six quality management system areas plus other applicable FDA requirements, drops QSIT's fixed sampling tables, and lets investigators choose records based on product risk and professional judgment.
The change quality teams feel first: FDA eliminated its longstanding policy of not requesting internal audit, supplier audit, and management review records. Under the QMSR-era program these records are reviewable — meeting minutes and audit files that were effectively private are now inspection evidence.
What changed and what stayed
Scoping the transition accurately matters more than moving fast. The QMSR changed the quality system backbone — it did not touch the rest of the device regulatory stack:
- Changed: QSR requirements replaced by ISO 13485:2016 incorporated by reference; terminology shifts to ISO vocabulary; risk-based thinking expected throughout, consistent with ISO 13485's integration of risk management principles; FDA additions at 820.35 (records) and 820.45 (labeling and packaging); QSIT replaced by the risk-based CP 7382.850 inspection program
- Unchanged: 21 CFR Part 11 (electronic records and signatures), Part 803 (medical device reporting), Part 806 (corrections and removals), Part 807 (registration and listing), Part 830 (UDI), Part 4 (combination products)
- Still true: FDA inspects directly — ISO 13485 certification is neither required nor accepted as a substitute for QMSR compliance
What a QMSR transition actually involves
For manufacturers with a mature QSR-era quality system, the transition is a structured gap assessment rather than a rewrite. The work concentrates in five places: mapping legacy procedures to ISO 13485 clauses plus the FDA additions; updating terminology and document references under change control; treating management review cadence, inputs, and minutes as producible records per ISO 13485 §5.6; re-pointing the internal audit program at the new requirement set; and closing the training loop on every revised procedure.
Because the new inspection program selects records by risk and can reach records QSIT could not, retrieval speed matters as much as record completeness — a record that exists but cannot be produced while an investigator waits is a finding in the making.
How Complere supports QMSR work
The QMSR transition is mostly document, change, audit, and training work — the workflows an eQMS governs. Complere supports the controlled document-update wave with Part 11-aligned approvals, runs the transition itself as impact-assessed controlled changes, plans gap assessments and re-pointed internal audits in Audit Management, ties training assignments to each revised procedure, and treats management review minutes as controlled, signed records. The full transition picture lives on the QMSR transition hub.
Frequently asked questions
Common questions about FDA QMSR sourced from regulatory references and inspection patterns.
When did the FDA QMSR take effect?
February 2, 2026. The final rule was published in the Federal Register on February 2, 2024, giving manufacturers a two-year transition. From the effective date, FDA inspects against the QMSR — there is no grace period.
Does the QMSR mean ISO 13485 certification satisfies FDA?
No. The QMSR incorporates ISO 13485:2016 by reference, but FDA neither requires nor accepts certification as evidence of compliance. FDA inspects manufacturers directly against the QMSR, which also adds FDA-specific requirements at 21 CFR 820.35 (records) and 820.45 (labeling and packaging).
What replaced QSIT under the QMSR?
Compliance program CP 7382.850, Inspection of Medical Device Manufacturers — a risk-based inspection approach organized around six QMS areas plus other applicable FDA requirements, with no fixed sampling tables. It also ended FDA's policy of not requesting internal audit, supplier audit, and management review records: those are now reviewable.
Is 21 CFR Part 11 affected by the QMSR?
No. Part 11 requirements for electronic records and signatures are unchanged. QMSR records kept electronically remain subject to Part 11 controls — audit trails, access control, and signature manifestation.
