EUDAMED risk class: I to III, A to D

A public EUDAMED device shows the risk class the manufacturer registered. MDR uses I to III. IVDR uses A to D. The class is not a certificate.

The risk class on a public EUDAMED device is the class in the registration, not a grade we assign from the trade name. Under the MDR the classes run I, IIa, IIb, and III, with the familiar subclasses for sterile, measuring, and reusable surgical instruments inside class I. Under the IVDR the classes run A, B, C, and D. The legislation field tells you which scale you are on.

What people expect the class to prove

A higher class often means a notified body was involved, so a certificate date is more likely to exist. It does not guarantee that the public certificate search will return one. Class I and class A devices often have no notified-body certificate to find. A blank expiry on those records is ordinary. A blank expiry on a class III record is a missing public row, not a reason to invent a date.

Two public examples: UDI-DI 16977660098955 is class I and has no public certificate expiry. UDI-DI 10887714028257 is class III and does. The class is one column. The certificate is another.

Filtering without downloading the register

The directory search can restrict a live query by risk class and by market status. That is a filter on the question you already asked, not a dump of every class III device in Europe. The page cap stays small on purpose. If you need a standing check on one class of device you buy, watch those UDI-DIs. A class change on a watched device is a diff, the same way a status change is.

The class string is copied from the public response. We do not collapse “IIa” into “II”, and we do not translate “Class III” into a clinical claim.

Not an official European Commission page. Public device and actor pages on this site repeat fields the register already publishes.
