21 CFR 820 is now the QMSR
In addition to providing QMSR transition information, we will now expand our focus to operationalizing ISO 13485 within FDA regulatory expectations. With that in mind, our first goals will be to provide information on QMSR interpretation, implementation, and audit readiness.
A Practical Perspective on Regulation
Rather than restate regulatory requirements, we will provide context and interpretation to help professionals understand how those requirements operate in real organizations.
Regulations define expectations, and quality systems translate those expectations into practice. And as the QMSR era begins, the most important question is no longer what the rule says, but how companies build quality systems that meet both regulatory requirements and real-world operational needs. And we aim to help answer that question.
Understanding the Transition to FDA’s Quality Management System Regulation
The U.S. Food and Drug Administration (FDA) has formally replaced the long-standing Quality System Regulation (QSR) with the Quality Management System Regulation (QMSR), aligning U.S. medical device quality system requirements with the international standard ISO 13485:2016.
This regulatory change represents one of the most significant shifts in FDA medical device quality regulation in decades. For manufacturers operating in the United States, the transition from 21 CFR Part 820 (QSR) to the QMSR framework requires careful evaluation of quality systems, documentation, and operational processes.
QSR-to-QMSR.com was created to help regulatory professionals, quality leaders, and medical device manufacturers understand and navigate this transition.
What Is the QMSR?
The Quality Management System Regulation (QMSR) incorporates ISO 13485:2016 by reference into FDA medical device regulations while maintaining certain FDA-specific requirements related to records, inspections, and postmarket activities.
The goal of the QMSR is to harmonize U.S. device regulation with international quality system standards, reduce duplicative regulatory requirements for global manufacturers, strengthen risk-based quality management across the device lifecycle, and improve regulatory consistency between FDA and other international regulators.
For many manufacturers already certified to ISO 13485, the QMSR represents a shift toward greater global alignment. However, organizations must still understand how FDA expectations intersect with the ISO framework.
From QSR to QMSR: What Changes?
While many foundational quality system principles remain the same, the transition introduces several important structural and terminology changes, including alignment with ISO 13485 quality management system structure, greater emphasis on risk-based quality management, integration of supplier controls and outsourced processes, updated terminology for device records and documentation, and continued FDA requirements for complaint handling, MDR reporting, and inspections.
Understanding how these elements interact is essential for maintaining regulatory compliance and preparing for FDA inspections in the QMSR era.
A Practical Perspective on Quality Systems
Regulations define expectations. And quality systems translate those expectations into practice.
As the medical device industry enters the QMSR era, the challenge for manufacturers is not simply compliance with regulatory text, but the development of robust, risk-based quality systems that support safe and effective medical devices throughout their lifecycle.
This site aims to help professionals navigate that transition.
