Summary

The EU Declaration of Conformity is a formal legal statement where you, as the manufacturer, declare under your sole responsibility that your medical device complies with all applicable regulatory requirements. This document serves as your official certification that the device meets EU MDR 2017/745 standards and can be legally placed on the European market.

Why is EU Declaration of Conformity important?

The EU Declaration of Conformity represents the final regulatory milestone before market entry in the EU. Without this document, you cannot legally sell your medical device in Europe. It serves as your legal guarantee to regulatory authorities, healthcare providers, and patients that your device has undergone proper conformity assessment procedures and meets all essential safety and performance requirements. This document also provides legal protection for your company by demonstrating due diligence in regulatory compliance and establishes traceability for post-market surveillance activities.

Regulatory Context

Under EU MDR 2017/745:

  • Article 19 mandates the Declaration of Conformity for all medical devices
  • Annex IV specifies the exact content requirements
  • Must be issued before CE marking and market placement
  • Required for all device classes with different conformity assessment routes

Special attention required for:

  • Class I devices (non-sterile, non-measuring, non-reusable): Self-declaration based on technical documentation
  • Class I (sterile, measuring, reusable), IIa, IIb, III: Notified body involvement required
  • Basic UDI-DI must be included and registered in EUDAMED
  • Person Responsible for Regulatory Compliance (PRRC) must be identified

Guide

Your EU Declaration of Conformity must include specific mandatory elements as defined by Annex IV of MDR 2017/745. The document structure follows a standardized format that regulatory authorities expect to see.

Essential Information Requirements

Manufacturer Details: Include your complete legal name, registered address, and contact information. If you’re not EU-based, you must also include your authorized representative’s details who acts on your behalf within the EU.

Device Identification: Provide your device’s product/trade name, software version, Basic UDI-DI, and intended purpose. The intended purpose must match exactly what you’ve defined in your technical documentation and cannot be broader than what you’ve validated.

Classification Information: State your device’s classification (Class I, IIa, IIb, or III) and provide the classification rule justification. This determines which conformity assessment procedure applies to your device.

Conformity Assessment Declaration

The conformity assessment section varies based on your device class:

Class I (non-sterile, non-measuring, non-reusable): Declare that conformity was demonstrated by drawing up technical documentation according to Annexes II and III and issuing the declaration according to Article 19 and Annex IV.

Class I (sterile, measuring, reusable) and higher classes: Reference the specific Annex IX procedures followed and include your notified body’s name and identification number if applicable.

Technical Standards Compliance

Include an Annex A listing all applicable technical standards your device complies with, such as:

  • EN ISO 13485:2016 for quality management systems
  • ISO 14971:2019 for risk management
  • IEC 62304:2006 for medical device software
  • IEC 62366-1:2015 for usability engineering

Signature Requirements

The EU declaration must be signed by someone with authority to bind the manufacturer legally. Typically this includes:

  • CEO or Managing Director representing overall company responsibility
  • Person Responsible for Regulatory Compliance (PRRC) confirming regulatory oversight

Document Control

Assign a unique document identifier and maintain version control. The EU declaration must be kept available for 10 years after the last device covered by it has been placed on the market.

Example

Scenario

You’ve developed a Class IIa software medical device for cardiac monitoring. After completing your technical documentation, risk management, clinical evaluation, and notified body assessment, you’re ready to create your Declaration of Conformity. Your notified body has issued a certificate confirming compliance with Annex IX procedures.
