EU Harmonized Standards for Medical Devices: What Changes in 2026

Key data

If you manufacture, import or distribute medical devices in the EU, this correction directly affects you. Commission Implementing Decision (EU) 2026/1231 modified the harmonized standards applicable under Regulation (EU) 2017/745, and corrections to that same decision are now being published. The practical result: the current versions of several key technical standards have changed, and your technical file must be aligned with them.

Compliance with harmonized standards is not optional if you want to benefit from the presumption of conformity with the essential requirements of the Medical Devices Regulation. Working with an erroneous or outdated version of the standard may invalidate your declaration of conformity.

What does this regulation establish?

The corrigendum adjusts Commission Implementing Decision (EU) 2026/1231, which in turn amended Commission Implementing Decision (EU) 2021/1182. The latter is the reference document that lists the harmonized standards applicable to medical devices under Regulation (EU) 2017/745.

The corrections affect the technical standards for the following product categories and areas:

The mechanism works as follows: when a manufacturer applies a harmonized standard published in the EU Official Journal, it is presumed to comply with the essential requirements of Regulation (EU) 2017/745 that the standard covers. If the standard contains errors and a corrigendum is published, the corrected version is the one that generates that presumption of conformity.

Economic and operational impact

The impact is not a direct fine, but a risk of commercial blockade. These are the specific scenarios your company may face:

• Commercialization blockade: If your technical file or declaration of conformity references versions of standards that have already been corrected and are not up to date, the notified body may reject or suspend certification.
• Market withdrawal: Market surveillance authorities may require the withdrawal of products whose documentation does not comply with the corrected standards in force.
• Recertification cost: Updating technical documentation, repeating tests or audits with the notified body generates direct costs that vary depending on product complexity and the affected standard.
• Launch delays: Products in the certification phase that use the affected standards may see their market entry delayed until the documentation is updated.

Who does it affect?

• Medical device manufacturers certifying under Regulation (EU) 2017/745 and applying any of the corrected harmonized standards.
• Manufacturers of electromedical equipment and transfusion equipment for medical use.
• Manufacturers of ophthalmic optics (lenses, frames, instruments).
• Manufacturers of non-active surgical implants (joint prostheses, bone implants, etc.).
• Manufacturers of washer-disinfectors for healthcare use.
• Manufacturers of prostheses external and internal.
• Manufacturers of sharps injury protection devices.
• Importers and distributors commercializing products in these categories in the EU and who must verify the conformity of products they place on the market.
• Notified bodies that audit and certify these products.
• Regulatory managers (RA Managers) and quality departments of companies in the sector.

Practical example

A Spanish manufacturer of non-active surgical implants (for example, hip prostheses) has its technical file prepared on the basis of harmonized standards published in Commission Implementing Decision (EU) 2021/1182, as amended by Decision 2026/1231.

Following the publication of this corrigendum, the harmonized standard applicable to its product category has been adjusted. If the manufacturer does not update its technical documentation to reference the corrected version, its declaration of conformity could be considered incomplete or incorrect in the next audit by its notified body.

The immediate step is for the regulatory manager to identify which specific standard of those affected applies to their product, compare the previous version with the corrected one, and update the technical file. If the change affects tests already performed, they will need to assess whether it is necessary to repeat them or if a documentary justification is sufficient.

What should companies do now?

1. Identify affected standards: Review which harmonized standards from the nine corrected categories apply to your products. Consult the version published in the EU Official Journal.
2. Compare versions: Contrast the version of the standard referenced in your current technical file with the corrected version to identify relevant differences.
3. Update technical documentation: Modify the technical file and declaration of conformity to correctly reference the standards in their corrected version.
4. Assess impact on testing: Determine whether the corrections affect testing requirements already executed or if a documentary update is sufficient.
5. Inform the notified body: Proactively communicate the changes to the notified body managing your certification to avoid surprises in the next audit.
6. Review products in launch phase: If you have products in the certification process, verify that the documentation in progress already incorporates the corrected versions.
