EU Technical Standards 2026: what changes for manufacturers and how it affects your certification

Key data

If your company manufactures or markets products in the EU that require conformity certification, this decision directly affects you. The Implementing Decision (EU) 2026/803, in force since 10 April 2026, updates the list of harmonized technical standards referenced in the Official Journal of the EU, amending the previous Decision 2023/2584.

Harmonized technical standards are the primary tool companies have to demonstrate that their products comply with European legal requirements. When a standard is updated or new standards are added to the official list, affected companies must review whether their certification remains valid or whether they need to adapt processes.

What does this regulation establish?

Decision 2026/803 introduces two types of changes to the EU's harmonized technical standards list:

• Update of already referenced standards: Versions of standards already listed in Decision 2023/2584 are updated. Companies using these standards must verify whether the new versions entail changes in their certification or conformity assessment processes.
• Addition of new referenced standards: New standards are incorporated into the official list. This may open or modify regulatory compliance pathways for certain industrial sectors, offering new routes to certify product or service conformity.

The complete list of affected standards is found in the updated annex to Decision 2026/803, available in the Official Journal of the EU. Quality and regulatory compliance managers must consult that annex to identify which specific standards apply to their products.

Economic and operational impact

The direct impact of this update depends on whether the modified or added standards are relevant to your company's products. Possible scenarios are:

• No immediate impact: If none of the updated standards apply to your products, you do not need to take urgent action beyond verification.
• Certification review: If a standard you use has been updated, you will need to evaluate whether the new version requires changes to your production processes, technical documentation, or tests. This may involve recertification costs with notified bodies.
• New opportunities: The addition of new referenced standards may facilitate access to the European single market for products that previously lacked a clear harmonized certification pathway.
• Commercial blocking risk: Non-compliance with current harmonized technical standards may create obstacles to commercialization in the European single market, including possible product withdrawal from the market.

Who does it affect?

This decision affects all companies whose activities depend on harmonized technical standards to certify product conformity in the EU:

• Manufacturers of industrial products requiring CE marking
• Companies marketing products in the European single market subject to technical directives or regulations
• Quality and regulatory compliance managers in manufacturing companies
• Certification bodies and testing laboratories applying harmonized standards
• Importers and distributors who must verify conformity of products they introduce to the European market
• Technical advisors and standardization consultants working with industrial companies

Practical example

A manufacturer of electrical equipment uses a specific harmonized technical standard to certify that its products comply with the Low Voltage Directive requirements. With the publication of Decision 2026/803, that standard has been updated to a new version in the official OJEU list.

The company's quality manager must:

1. Locate the updated standard in the annex of Decision 2026/803.
2. Compare the technical requirements of the previous version with those of the new version.
3. Determine whether the changes affect product design, tests performed, or existing technical documentation.
4. If there are substantial changes, coordinate with the corresponding notified body to update the certification before the previous version ceases to be valid.

If the company does not perform this verification and continues to market the product under the previous standard without checking its validity, it may face obstacles to commercialization within the European single market.

What should companies do now?

1. Download the updated annex of Decision 2026/803 from the Official Journal of the EU and review which standards have been modified or added.
2. Identify which standards from the list apply to your products by cross-referencing the annex with the standards your company currently uses to certify conformity.
3. Evaluate the impact of updated versions by comparing the technical requirements of the previous version with those of the new referenced version.
4. Consult with the notified body or technical manager if changes in standards require updating technical documentation, repeating tests, or modifying production processes.
5. Review whether newly added standards open more favorable compliance pathways for any of your products or business lines.
6. Update your conformity management system to reflect current standards and prevent obsolete versions from continuing to be referenced in technical documentation.
