ISO 13485 Clause 4.2 restructures the way medical device manufacturers think about documentation — collapsing the DMR, DHR, and DHF into the Medical Device File, and eliminating the old QSR exemption that kept your audit reports out of FDA’s hands. Here’s what that means in practice.
Your contract manufacturer has ISO 13485 certification and a solid QMS. That’s great — and it still doesn’t satisfy your oversight obligations as the legal manufacturer. Here’s what QMSR and ISO 13485 actually require of each party when manufacturing is outsourced.
Section 820.45 is one of only two places in the entire QMSR where FDA stepped in and said ISO 13485 wasn’t sufficient. That’s worth paying attention to — especially if device labeling errors have ever appeared on your watch.
Section 820.35 is where the QMSR gets specific about records — particularly complaint files and servicing records. It’s not dramatically different from what you were doing under the old QSR, but there are real changes worth knowing, and one of them involves UDI.
Section 820.7 is three short paragraphs, and most people skim right past it. Don’t. It’s the provision that turns ISO 13485:2016 from a helpful standard into a legal requirement — and it fundamentally changes how you read the entire QMSR.
Section 820.10 is where the QMSR stops asking whether you have a quality system and starts asking whether it actually works. Clara explains what ‘demonstrate’ really means to FDA, what changed from the old QSR, and how to make sure your QMS can stand up to scrutiny.
Definitions sections rarely get the attention they deserve — until an audit, when suddenly the precise meaning of ‘manufacturer’ or ‘design history file’ matters enormously. Clara walks through the QMSR’s key terminology changes and why they’re worth your time.
The QMSR’s scope section looks simple — it’s one page in the regulation. But understanding exactly who is covered, and how the QMSR handles some edge cases the old QSR left fuzzy, is worth your time. Clara walks you through it.
FDA’s new Quality Management System Regulation took effect February 2, 2026. Here’s a clear-eyed look at what changed, what it means for manufacturers already under ISO 13485, and what to expect from this section-by-section series.
