When a medical device recall is put down to a "labeling or packaging issue," the picture most people have is physical: a broken seal, a compromised sterile barrier, a production line fault. Often, the problem is simpler than that. The label, the carton, or the Instructions for Use said the wrong thing.
That distinction matters, because it changes where a quality team should look. A text or documentation error isn't fixed by better materials or tighter production controls. It's fixed at the point where labeling is verified before release.
How FDA Classifies Recalls
FDA sorts every device recall into one of three classes based on the health risk involved, as defined by the agency:
- Class I: a reasonable probability the product will cause serious adverse health consequences or death.
- Class II: the product may cause temporary or medically reversible adverse health consequences, or the probability of serious consequences is remote.
- Class III: the product is not likely to cause adverse health consequences.
Two points are easy to miss. First, recall classes are not the same as device classes: a low-risk Class I device can be the subject of a serious Class I recall, and the reverse. Second, labeling errors appear across all three. A wrong expiry date or missing statement may land in Class III. An IFU with an incorrect instruction for a critical device can land in Class I. Class II is by far the most common recall class overall, and that's where many labeling discrepancies end up.
Instructions for Use Are Their Own Risk Category
IFU errors deserve particular attention because their consequences are direct. A clinician or patient following an IFU is relying on it to be accurate. A missing step, an incorrect setting, or a warning that dropped out of one language version can each become a patient safety event.
IFUs are also among the most frequently revised documents in a device manufacturer's labeling portfolio. Each revision, whether it's a new contraindication, a regulatory update, or a translation fix, carries the same risk as any other label change: the edit is made in one place, the rest of the document isn't systematically re-verified against the approved master, and an error survives into the released version. We walk through a real-world version of this in The IFU Error That Started With One Character.
What Changed in 2026: Label Inspection Is Now Explicit
On February 2, 2026, FDA's Quality Management System Regulation (QMSR) replaced the old Quality System Regulation, incorporating ISO 13485:2016 into 21 CFR Part 820.
FDA kept one section of its own on labeling, 820.45, because it judged ISO 13485's labeling coverage insufficient. It requires manufacturers to inspect labeling for accuracy before release, and to document that release. So verifying labels before they ship isn't just good practice for US device manufacturers. It's a specific, inspectable requirement, and investigators now work from an updated compliance program built around the QMSR.
The Process Gap Behind Labeling Recalls
Across labeling-related recalls, the same gap tends to appear: no systematic, documented comparison between the released labeling and the approved master at the point of release.
That isn't about reviewers not reading carefully. It's that manual review is an unreliable way to catch the specific errors that cause labeling recalls:
- A single character that changes a value, such as a dosage, size, or expiry date
- A change propagated to some language versions but not others
- A mismatch between packaging levels, where the unit label is right and the case label isn't (covered in our UDI Labeling Requirements guide)
- A comparison run against the previous draft instead of the approved master, so an older error passes unnoticed (see our Document Version Control guide)
The device manufacturers with the strongest labeling records aren't the ones with the most careful reviewers. They're the ones whose final check doesn't rely on human attention alone.
For a practical pre-release review, our Medical Device Labeling Audit Readiness Checklist covers the checks that matter most, and the Medical Device Labeling Requirements guide covers the full regulatory picture.
Content Compare verifies device labels, IFUs, and every language and packaging-level variant against the approved master before release, with a documented audit trail for every comparison. See how it works on your own labeling.
