EU MDR Compliance Deadlines 2026 — Full Timeline & Action Checklist

To ensure your compliance strategy lines up with these timelines, read our comprehensive guide to conducting an EU MDR Gap Analysis.

EU MDR deadlines have been extended three times since the regulation came into force. Many manufacturers assume another extension is coming. It is not. The European Commission confirmed in 2024 that the current timeline is final. This guide gives you every confirmed date, what it means for your device class, and what you must do now. To avoid critical compliance failures under the new timeline framework, companies must undergo an immediate MDR gap assessment.

What You Must Do Before Each Deadline

• Before 28 May 2026 — Register in EUDAMED (SRN mandatory). No registration = no EU market access from this date.
• Before December 2027 — Class III and implantable Class IIb devices must hold a valid MDR certificate from a Notified Body.
• Before December 2028 — Class IIa and non-implantable Class IIb transition complete. All devices must be certified under EU MDR.
• Before May 2027 — Reusable surgical instruments require UDI on the device label.
• Now — Appoint your EU Authorized Representative if you are a non-EU manufacturer. Notified Body slots are fully booked 12–18 months in advance.

The confirmed deadline table — no further extensions

The EUDAMED deadline — 25 days away

28 May 2026 is no longer theoretical. EUDAMED (the European Database on Medical Devices) becomes mandatory for every entity in the EU medical device supply chain. This is the most immediate deadline and applies to every manufacturer regardless of device class.

After this date, any manufacturer, EU Authorized Representative, importer or distributor without a valid SRN (Single Registration Number) cannot legally place devices on the EU market. Competent Authorities in each member state will act immediately — no warning letters, no grace period.

What you need before 28 May 2026:

• An appointed EU Authorized Representative (mandatory for non-EU manufacturers)
• Actor registration in EUDAMED — your AR handles this on your behalf
• SRN issued and confirmed
• Each device linked to your SRN and your EU AR's SRN

What each device class must do now

Class I devices (self-declared — no Notified Body required)

Class I devices do not require a Notified Body for CE marking — but this does not mean there is nothing to do. You still need:

• Technical documentation in Annex II and Annex III format under EU MDR 2017/745
• Declaration of Conformity issued by the manufacturer
• EUDAMED registration — mandatory from 28 May 2026 regardless of class
• EU Authorized Representative if you are not established in the EU

Class IIa devices — act by end of 2026

Class IIa devices require a Notified Body audit. With average EU MDR review times of 13–18 months, and a December 2028 final deadline, you should be submitting your technical file to a Notified Body no later than mid-2027. Realistically, if you want to avoid a rushed submission, you should begin your NB application now.

Class IIb implantable devices — act immediately

The deadline for Class IIb implantable devices is 31 December 2027 — 19 months from now. With a 13–18 month Notified Body review, you have almost no buffer remaining. Your technical file must be submission-ready within weeks, not months.

Class III devices — the tightest deadline

Class III devices (highest risk) also face the December 2027 deadline. Some Notified Bodies are reporting review times of up to 24 months. If you have not already engaged a Notified Body and submitted your application, you are behind schedule.

The Notified Body bottleneck — why you cannot wait

There are currently 24 Notified Bodies designated under EU MDR — significantly fewer than the 58 that existed under the old MDD system. Audit slots are limited. Several major NBs are reporting full calendars into 2026 and beyond.

Manufacturers who wait until mid-2026 to begin their NB process for Class III or IIb implantable devices will almost certainly miss the December 2027 deadline and face market suspension.

Five-minute compliance checklist

• EUDAMED actor registration — complete before 28 May 2026
• SRN confirmed — required for all devices on the EU market
• EU Authorized Representative appointed — mandatory for all non-EU manufacturers
• Device linked in EUDAMED — must reference both your SRN and your EU AR's SRN
• Technical documentation — Annex II/III under EU MDR 2017/745, not MDD format
• Notified Body selected (Class IIa+) — application submitted, audit date confirmed
• Declaration of Conformity — updated to EU MDR reference

What happens if you miss a deadline

Missing the EUDAMED deadline (28 May 2026) results in immediate market suspension. Devices are removed from sale until registration is complete. There is no warning process and no appeals period during which you can continue trading.

Missing the Notified Body certification deadlines (2027–2028) by class results in the CE mark being void. Devices cannot be placed on the market or transferred further in the supply chain until valid MDR certification is in place.
