# EU MDR deadlines and compliance calendar

Official source EU MDR calendar for application, legacy-device transition, UDI, EUDAMED, and recurring QMS, technical documentation, clinical, PMS, vigilance, certificate, and change reviews.

*Compliance Calendar* *EU MDR*

## EU MDR deadlines and compliance calendar

A cited calendar for MDR application, legacy-device transition dates, UDI carrier timing, EUDAMED module timing, and recurring operational reviews.

Use it to separate fixed legal dates from ongoing review events for QMS, technical documentation, clinical evaluation, PMS, vigilance, certificates, and design or intended-purpose changes.

This EU MDR calendar focuses on cited dates and repeatable compliance review events. It does not add national filing dates, invented submission windows, or generic project-management milestones. Timings on this page are tied to cited sources; verify current legal source language before implementation decisions.

## Fixed MDR transition and application dates

Use these dates as the backbone of an MDR calendar. For each device family, record the applicable risk class, certificate basis, notified-body status, whether the legacy conditions are still met, and the owner responsible for keeping evidence current.

Legacy-device transition dates are conditional. Regulation (EU) 2023/607 ties the extended placement or putting-into-service windows to continued Directive compliance, no significant design or intended-purpose change, no unacceptable public-health risk, QMS implementation by 26 May 2024, a notified-body application by 26 May 2024, and a written notified-body agreement by 26 September 2024.

- 26 May 2021: MDR date of application for medical devices after the COVID-era one-year postponement.
- 26 May 2024: deadline, for eligible legacy devices relying on Article 120 transition, to have a QMS in place and lodge the formal MDR conformity-assessment application with a notified body.
- 26 September 2024: deadline for the notified body and manufacturer to sign the written agreement for eligible legacy devices relying on the extended transition.
- 26 May 2026: transition endpoint for class III custom-made implantable devices without a notified-body certificate, where the Article 120(3f) conditions are met.
- 31 December 2027: transition endpoint for eligible class III devices and class IIb implantable devices, except the listed lower-risk implantable items.
- 31 December 2028: transition endpoint for eligible other class IIb devices, class IIa devices, class I sterile or measuring devices, and certain devices newly requiring notified-body involvement under the MDR.

## Check your MDR calendar against device evidence

Review transition eligibility, UDI status, EUDAMED readiness, certificate dependencies, and recurring QMS, clinical, PMS, vigilance, and change-control reviews for each device family.

- [Talk through implementation](/contact.md): Review your device calendar, source evidence, and operating controls.

## UDI and EUDAMED calendar entries

Track UDI and EUDAMED separately from the legacy-device transition. UDI assignment, UDI carrier placement, direct marking, database readiness, and EUDAMED account access can have different owners and review evidence.

For UDI data, the operating control should include a change trigger: where a device data element changes but a new UDI-DI is not required, the MDR UDI database rule requires the relevant record to be updated within 30 days.

- 26 May 2021: UDI assignment obligation applies for medical devices.
- 26 May 2021: UDI carrier placement deadline for implantable devices and class III devices.
- 26 May 2023: UDI carrier placement deadline for class IIa and class IIb devices; direct marking deadline for reusable implantable and class III devices.
- 26 May 2025: UDI carrier placement deadline for class I devices; direct marking deadline for reusable class IIa and class IIb devices.
- 26 May 2027: direct marking deadline for reusable class I devices.
- 28 May 2026: mandatory use starts for the first four EUDAMED modules: Actor, UDI/devices, notified bodies and certificates, and market surveillance.

- [Regulation (EU) 2017/745 on medical devices](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32017R0745&locale=en&ref=sorena.io) - Grounds UDI carrier timing by device class, reusable-device direct marking, and UDI database maintenance including 30-day updates where no new UDI-DI is required.

## Recurring operational reviews to put on the calendar

Not every MDR calendar entry is a fixed filing deadline. Many controls are ongoing obligations that should be scheduled as review events with a trigger, evidence owner, and output record.

Set the cadence by device risk, certificate commitments, PMS plan, PMCF plan, notified-body agreement, and change-control procedure. Avoid publishing a date unless the source or the approved quality record actually sets one.

- QMS review: confirm procedures remain implemented, maintained, kept up to date, and continually improved; include design changes, standard or common-specification changes, supplier changes, PMS outputs, vigilance signals, and corrective actions.
- Technical documentation review: verify Annex II and Annex III files remain up to date, including device description, specifications, risk management, verification and validation, PMS plan, PMCF plan, and links to certificates or declarations.
- Clinical evaluation review: update the clinical evaluation plan, literature review, clinical data appraisal, clinical evaluation report, PMCF findings, and benefit-risk conclusions when PMS or PMCF evidence changes.
- PMS and vigilance review: review post-production experience, complaints, incidents, field safety corrective actions, PMCF outputs, and preventive or corrective actions; serious incidents and field safety corrective actions must be reported as soon as the manufacturer learns of them.
- Certificate and notified-body review: track certificate expiry or validity, surveillance responsibility, written agreements, scope changes, restrictions, and whether transition conditions continue to be satisfied.
- Change review: screen every design, intended-purpose, label, packaging, UDI data, critical warning, contraindication, sterility, model, or trade-name change before release, because some changes can end transition eligibility or require a new UDI-DI.
