What is QMSR, and how does it affect me?

In short: The Quality Management System Regulation replaced FDA's QSR in February 2026, incorporating ISO 13485 by reference. US-facing manufacturers now run an ISO 13485-aligned QMS with FDA-specific additions. Teams already building a 13485 QMS for CE marking are largely covered; QSR-era documentation needs updating.

What actually changed

FDA's Quality System Regulation (QSR), the long-standing US-specific quality management framework, was replaced by the Quality Management System Regulation (QMSR), effective 2 February 2026. Rather than maintaining a separate US-specific standard, QMSR incorporates ISO 13485:2016 by reference as the baseline, with a smaller set of FDA-specific additions layered on top — device labeling and recordkeeping requirements, and clarifications on terms like "management with executive responsibility" that don't map one-to-one between the two frameworks. The practical effect is convergence: FDA and the EU are now, for the first time, working from largely the same underlying quality standard rather than two parallel systems.

What this means if you're already building for CE marking

If your team is building an ISO 13485-certified QMS for EU MDR purposes, most of that system now directly serves your US regulatory obligations too — you're not building two separate quality systems, you're building one and layering FDA-specific requirements on top. This is a genuine efficiency gain for teams sequencing EU and US market entry, and it's part of why a single QMS build, rather than parallel EU and US systems, is now the more efficient default.

What needs updating if you're QSR-legacy

If your existing quality system was built specifically against the older QSR structure — organized around QSR's own subpart headings rather than ISO 13485's clause structure — it needs mapping and, in places, restructuring to align with QMSR's incorporated-by-reference approach. This isn't necessarily a rebuild from scratch, but a genuine gap analysis against ISO 13485's structure is worth doing rather than assuming your existing QSR documentation transfers cleanly.
