Do I still need ISO 13485 certification under QMSR?

FDA does not require ISO 13485 certification, only conformity with the incorporated requirements. Certification remains useful for EU MDR, MDSAP, and customer expectations, but is not a US market prerequisite.

What is different between QSR and QMSR?

QMSR uses ISO 13485:2016 terminology (medical device file vs device master record, process validation vs production and process controls), incorporates ISO 9000 definitions, and adds FDA-specific requirements for UDI, labeling controls, records access, and reporting. Design controls, CAPA, and complaint handling remain, restructured to align with ISO 13485.

Will FDA continue to issue Form 483 observations under QMSR?

Yes. The inspection framework and enforcement tools (Form 483, warning letters, consent decrees) are unchanged. Observations will cite the amended Part 820 provisions and, indirectly, the incorporated ISO 13485 clauses.

Quality Management System Regulation

FDA's harmonized successor to the QSR, incorporating ISO 13485:2016 by reference.

Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed May 5, 2026

Definition

Issued in 2024 and effective in 2026, the Quality Management System Regulation amends 21 CFR Part 820 to incorporate ISO 13485:2016 by reference, with additional FDA-specific requirements for records, labeling, and complaint reporting.

What this means in practice

QMSR aligns U.S. quality system expectations with international practice while retaining FDA-specific requirements around records access, labeling, unique device identification, complaint files, and servicing. Effective February 2, 2026, QMSR replaces the previous 21 CFR Part 820 QSR structure. Manufacturers must reconcile procedures, terminology (device master record vs medical device file), and records strategies before the effective date, and update supplier agreements and training programs to reflect the ISO 13485:2016 vocabulary.

Examples

A Class II manufacturer remapping its QSR-based procedures (DMR, DHF, DHR) to the ISO 13485 medical device file structure while retaining FDA-required records access clauses.
A software-only SaMD company adopting ISO 13485:2016 as the QMS backbone with QMSR overlays for UDI and complaint file requirements.

Common pitfalls

•Assuming ISO 13485 conformance alone is sufficient under QMSR. FDA retains specific provisions for records access, labeling, UDI, complaint files, and servicing.
•Waiting until 2026 to start the transition. Auditors expect evidence of a planned, documented harmonization effort well before the effective date.
•Retiring QSR terminology (DMR/DHF/DHR) without a cross-reference matrix, which breaks traceability across legacy records.
•Ignoring supplier agreements. Many quality agreements reference 21 CFR Part 820 clauses that no longer exist under QMSR.

Frequently asked questions

February 2, 2026. On that date, the amended 21 CFR Part 820 incorporating ISO 13485:2016 by reference becomes enforceable. FDA has stated it will continue routine inspections against the new framework from day one.
