How to Get MDR Certification for Class I Medical Devices

To sell medical devices in the EU, you need CE marking under the Medical Device Regulation (MDR). Class I devices follow different conformity assessment routes. Some need certification from a Notified Body, while others rely on the manufacturer’s own declaration. While every route demands the same rigorous compliance, knowing which route applies is the first step toward Class I MDR certification.

What MDR Certification Means for Class I Devices

The EU MDR sets the rules every medical device must meet before it reaches the European market. At its core are the General Safety and Performance Requirements (GSPR), which cover device safety, performance, risk management and labeling.

MDR certification is the certificate a Notified Body issues after assessing a device against those requirements. A Notified Body is an organization designated by an EU member state to carry out these assessments. Whatever the route, you remain legally responsible for your device’s conformity and must back the CE mark with documented evidence.

How Class I Subcategories Shape Your Certification Route

Class I splits into four groups under MDR Annex VIII:

• Standard Class I: Nonsterile devices with no measuring function that aren’t reusable surgical instruments. The manufacturer issues the EU Declaration of Conformity under its own responsibility.
• Class Is: Sterile devices. A Notified Body assesses the sterility aspects.
• Class Im: Devices with a measuring function. A Notified Body assesses the measuring aspects.
• Class Ir: Reusable surgical instruments. A Notified Body assesses the reuse aspects.

For Class Is, Im and Ir devices, Notified Body involvement covers only those specific aspects.

Manufacturers already hold prime responsibility for CE marking under EU rules. Whichever route applies, you need the personnel, systems and expertise to compile technical documentation, conduct clinical evaluations and manage post-market surveillance.

Key Steps to MDR Compliance for Class I Devices

Every Class I device moves through a structured compliance process. The pathway includes the following steps:

• Confirm the device’s classification under MDR Annex VIII.
• Establish a quality management system (QMS) per MDR Article 10(9) that addresses design, manufacturing and post-market activities.
• Compile technical documentation per Annexes II and III, including risk management files, labeling specifications and evidence of GSPR conformity.
• Conduct a clinical evaluation, often literature-based, for Class I devices to demonstrate safety and performance.
• Designate a person responsible for regulatory compliance (PRRC) in accordance with MDR Article 15.
• Obtain Notified Body certification if your device is Class Is, Im or Ir.
• Draft the EU Declaration of Conformity and affix the CE mark.
• Register the manufacturer and device in EUDAMED and implement a post-market surveillance system.

Each step requires documented information, internal resources and ongoing oversight, and the Medical Device Coordination Group guidance documents explain how to apply the regulation in practice. EUDAMED registration also supports the MDR’s transparency goals.

Where Class I Compliance Breaks Down

Market surveillance authorities actively monitor the EU market. Because no independent assessor reviews a standard Class I technical file before launch, its strength rests on your internal processes. Weak quality management systems and incomplete documented information are common failure points that can lead to corrective action requests or market withdrawal.

A Notified Body provides independent verification for Class Is, Im and Ir devices, while ISO 13485 certification from an accredited certification body can demonstrate that your QMS is ready to support long-term compliance.

How NQA Provides MDR Certification With Kiwa

Manufacturers whose Class I devices need Notified Body involvement can pursue MDR certification through National Quality Assurance (NQA), an accredited certification body with head offices in the UK, U.S. and China. NQA offers MDR certification supported by Kiwa, a designated EU Notified Body. Kiwa, not NQA, holds the Notified Body role, so you gain the backing of a designated EU Notified Body.

How ISO 13485 Certification Supports Your MDR Compliance

ISO 13485 certification is separate from MDR certification. It assesses your quality management system rather than your device and doesn’t replace the MDR conformity assessment.

NQA certifies organizations to ISO 13485, the international standard for medical device quality management systems, which closely aligns with the QMS requirements of the EU MDR and supports compliance for Class I medical devices. NQA’s accredited ISO 13485 certification services assess your documented information against the standard, and its readiness assessments identify gaps before certification.

Every NQA audit also identifies opportunities for improvement, and certification to ISO 13485 can enhance risk management and provide proven business credentials.

Why the Right Certification Route Supports Long-Term EU Access

Class I MDR compliance works best when you match your device to the correct route from the start. A verified QMS strengthens every route, and NQA supports both needs with MDR certification backed by Kiwa and accredited ISO 13485 certification. Partnering with NQA can help you navigate MDR certification, strengthen your QMS and meet EU standards for long-term market access.
