If you manufacture, import or distribute radio equipment in Europe, you have a potential issue from 4 September 2026. The Implementing Decision (EU) 2026/2003 modifies the list of harmonized standards of the RED Directive (Radio Equipment Directive), which means that the normative references supporting your CE marking may have changed. Without the correct references, your product loses the presumption of conformity and cannot be legally commercialized in the European single market.
This decision modifies the Implementing Decision (EU) 2022/2191 and also corrects errors contained in the Implementing Decision (EU) 2025/2499. It is not a minor procedural change: it is an update of the technical regulatory map that defines which standards guarantee compliance with the essential requirements of the RED Directive.
What does this regulation establish?
The RED Directive establishes the essential requirements that radio equipment must meet in order to be commercialized in the EU. Harmonized standards are technical standards whose compliance automatically grants "presumption of conformity" with those essential requirements — that is, if your product complies with the applicable harmonized standard, it is presumed to comply with the Directive without need for further demonstration.
Decision 2026/2003 updates the official list of these standards for the following product categories:
| Equipment category | Description |
|---|---|
| Radio determination equipment | Location tracking applications |
| Cellular base stations | Cellular communications (mobile networks) |
| Ultra-wideband (UWB) devices | High-precision short-range communications |
| Material sensor devices | Detection and analysis of materials by radiofrequency |
| Fixed radio systems | Fixed radiocommunication infrastructures |
| Tank level radar sounding equipment | Level measurement in industrial tanks |
| Amplifiers | Radiofrequency signal amplification |
| Active antennas | Antennas with integrated processing electronics |
| Air traffic control sensors | Radar equipment and sensors for airspace management |
| Other radio equipment | Additional categories covered in the decision |
For each of these categories, the decision updates or incorporates new references to harmonized standards (ETSI and CENELEC standards, primarily). Compliance with these updated standards is the most direct way to maintain valid CE marking.
Economic and operational impact
The impact is not a direct fine or a new tax. The economic risk is more subtle but equally serious: the loss of the right to commercialize in the European single market if the product's technical documentation is no longer aligned with the current harmonized standards.
The concrete operational costs that this update can generate include:
- Review and update of the EU Declaration of Conformity for each affected product, with reference to the new harmonized standards.
- Update of the product's technical file to reflect the new applicable standards.
- Possible new tests or laboratory trials if the updated standards introduce technical requirements different from the previous ones.
- Review of contracts with suppliers and notified bodies if the conformity assessment process is affected.
- Withdrawal or blocking of products from the market in case of inspection by market surveillance authorities, if the documentation is not updated.
For companies with broad portfolios of radio equipment, the cost of documentary review can be significant. For niche manufacturers with one or two affected products, the impact is more limited but equally urgent.
Who does it affect?
- Manufacturers of radio equipment established in the EU that commercialize any of the listed categories.
- Importers that introduce radio equipment manufactured outside the EU into the European market: they are responsible for verifying that the manufacturer complies with the updated regulation.
- Distributors that make radio equipment available in the European market and must verify the conformity of the products they distribute.
- R&D and certification departments of telecommunications, defense, industrial and aviation companies that develop or certify equipment in the affected categories.
- Quality and regulatory compliance managers (Compliance Officers) of companies in the electronics and telecommunications sector.
- Notified bodies that perform third-party conformity assessments for this equipment.
Practical example
A Spanish company manufacturing tank level radar sounding equipment for the chemical industry has its products certified under the RED Directive, with an EU Declaration of Conformity that references the harmonized standards contained in Decision 2022/2191.
With the entry into force of Decision 2026/2003 on 4 September 2026, the normative references applicable to that product category have been updated. If the company does not review its Declaration of Conformity and its technical file to incorporate the new references, its products continue to carry CE marking, but that marking is no longer supported by the current harmonized standards.
In a market surveillance inspection, the competent authority could consider that the product does not meet the essential requirements of the RED Directive and order its withdrawal from the European market — with the reputational, logistical and economic cost that entails. The solution is to proactively review which harmonized standards now apply to each product and update the technical documentation before that inspection arrives.
What should companies do now?
- Identify affected products: review your own catalog and determine which radio equipment belongs to any of the nine categories updated by Decision 2026/2003.
- Consult the new applicable harmonized standards: access the full text of Decision 2026/2003 in the EU Official Journal and identify which specific normative references have been added, modified or removed for each category.
- Evaluate the technical impact: determine whether the new harmonized standards introduce technical requirements different from those that require new laboratory tests or if it is sufficient to update the documentation.
- Update the EU Declaration of Conformity: incorporate references to the current harmonized standards in all affected products.
- Update the technical file: ensure that the technical file of each product reflects compliance with the updated standards.
- Communicate to the distribution chain: inform distributors and importers of the changes so they can verify the conformity of the products they commercialize.
- Review the correction of Decision 2025/2499: if any product was referenced under standards of that decision, verify that the corrected errors do not affect the validity of the existing documentation.
Frequently asked questions
What is the presumption of conformity and why is it key for CE marking?
The presumption of conformity is the mechanism by which, if a product complies with a harmonized standard published in the EU Official Journal, it is automatically presumed to comply with the essential requirements of the RED Directive. This greatly simplifies the CE marking process, as the manufacturer does not have to demonstrate compliance with each essential requirement independently. If the harmonized standards applicable to your product change, you must update your documentation to continue to benefit from this presumption.
When did Decision 2026/2003 enter into force and from when must I comply with it?
Implementing Decision (EU) 2026/2003 entered into force on 4 September 2026, the date of its adoption by the European Commission, and was published in the Official Journal on 7 September 2026. Compliance is required from that date for all manufacturers, importers and distributors of radio equipment affected by the updated categories.
What happens if my product already has CE marking but the harmonized standards have changed?
The CE marking itself does not automatically disappear, but the presumption of conformity that supported it may become ineffective if the harmonized standards referenced in your Declaration of Conformity are no longer current. In a market surveillance inspection, authorities may question the validity of the marking and, in case of non-compliance, order the withdrawal of the product from the European market. The recommended action is to update the Declaration of Conformity and the technical file with the new normative references.
What categories of radio equipment are affected by this update?
Decision 2026/2003 updates the harmonized standards for: radio determination equipment for location tracking, cellular communication base stations, ultra-wideband (UWB) devices, material sensor devices, fixed radio systems, tank level radar sounding equipment, amplifiers, active antennas, air traffic control sensors and other additional radio equipment covered in the decision.
What previous standard does this decision modify and what corrections does it include?
Decision 2026/2003 modifies Implementing Decision (EU) 2022/2191, which was the reference list of harmonized standards under the RED Directive. Additionally, it corrects errors contained in Implementing Decision (EU) 2025/2499. If your technical documentation referenced standards from Decision 2025/2499, you must verify that the corrected errors do not affect the validity of your conformity declarations.
