Class C IVD manufacturers: Only one month left – Don’t lose EU market access
Submit your formal Notified Body applications by 26 May 2026
The deadline for transitioning legacy Class C IVDs is fast approaching. Manufacturers of devices that were self-declared under the IVDD but are now classified as Class C under the IVDR need to take urgent action to avoid losing market action. To take advantage of the extended transition period until 31 December 2028, they must submit their formal applications to an EU Notified Body no later than 26 May 2026 This requirement is in accordance with Article 110(3c)(e) of the IVDR [as amended by Regulation (EU) 2024/1860].
Under the IVDR, Class C IVDs now require Notified Body involvement for conformity assessment, marking a significant change from the IVDD self-declaration route. To avoid disruption to patient care and supply chains, the European Commission introduced extended transitional periods for “legacy” devices lawfully placed on the market before 26 May 2022.
For these legacy Class C devices, market access can continue until 31 December 2028, provided the conditions set out in Article 110(3c) are met, most notably, the timely submission of a formal application to a Notified Body.
This table summarizes the key deadlines applicable to Class C self-certified IVDs:

Beware of these common pitfalls
To ensure a smooth and timely submission, pay close attention to these common pitfalls:
- Misclassified devices - double-check and confirm your IVDR classification rationale
- Incorrect transition timelines - confirm which devices genuinely qualify as legacy devices under Article 110
- Late engagement - delaying action significantly increases the risk of missed deadlines, delays, or loss of eligibility
