Yes. Following Commission Decision (EU) 2025/2371, four EUDAMED modules became mandatory on 28 May 2026. New MDR and IVDR devices must be registered before being placed on the EU market, and legacy devices still being supplied must be registered by 28 November 2026.

Question 2

What is the difference between a Basic UDI-DI and a UDI-DI?

Accepted Answer

The Basic UDI-DI is an EU grouping key that bundles devices sharing the same intended purpose, risk class, and essential design characteristics. It anchors technical documentation and EUDAMED records and never appears on the label. The UDI-DI identifies one specific version or model and does appear on the label.

What changes require a new Device Identifier?

Accepted Answer

Any change creating a new version or model: a new size or dimension, a change in labeled quantity, a change in sterility, clinically relevant specification changes, or a new brand name or model designation. Cosmetic label updates generally do not.
