# RED DoC and CE marking file: what to include

FAQ answer for Radio Equipment Directive declarations of conformity, CE marking evidence, technical documentation, notified-body records, and related labels.

*FAQ* *EU*

## RED DoC and CE marking file contents

Under the Radio Equipment Directive, the manufacturer draws up technical documentation, performs or has performed the relevant conformity assessment, issues the EU declaration of conformity, and affixes the CE marking when compliance is demonstrated.

This FAQ explains what to keep in the RED DoC and CE marking file without turning the record into generic compliance paperwork.

A RED declaration of conformity and CE marking file should let a reviewer connect one radio equipment type to its technical documentation, conformity assessment route, EU declaration, CE marking, and any required supporting labels or certificates. The minimum record is not just a signed DoC; it is the evidence package showing how the manufacturer demonstrated the applicable RED requirements before placing the equipment on the EU market.

## Short answer: what the RED DoC and CE marking file should include

Keep the EU declaration of conformity or simplified declaration, the Annex V technical documentation, the conformity assessment record under Article 17, proof of CE marking under Articles 19 and 20, and the product identification that links those records to the exact radio equipment type.

The EU declaration itself should follow the Annex VI structure: radio equipment identification, manufacturer or authorised representative details, statement that the declaration is issued under the manufacturer's sole responsibility, object of the declaration, Directive 2014/53/EU and other applicable Union harmonisation legislation, standards or technical specifications used, notified-body intervention where applicable, covered accessories, components, and software where applicable, and signature details.

If the product uses a simplified declaration, keep the simplified wording with the equipment and make sure the full EU declaration is available at the exact internet address stated in the simplified declaration.

- Product link: type, batch or serial number, model designation, photographs or illustrations, marking, and any software or firmware version that affects conformity.
- Technical file: Article 21 and Annex V evidence, including design information, standards or other technical specifications, test reports, design calculations or examinations, copy of the EU declaration, and explanations required for spectrum operation and use restrictions.
- Conformity route: the Article 17 procedure used, including internal production control, EU-type examination plus conformity to type, or full quality assurance as applicable.
- Notified-body record: EU-type examination certificate and annexes when Annex III was used, or the notified-body identification number following the CE marking when Annex IV was used.
- Market-facing evidence: CE marking placement, packaging CE mark, instructions and safety information, frequency band and maximum transmitted power information for intentional transmitters, and Article 10(10) restriction information where relevant.

## Technical documentation to keep behind the RED DoC

Article 21 requires technical documentation to contain the relevant data or means used to ensure the radio equipment complies with the essential requirements. Annex V lists the minimum elements wherever applicable, so the file should be organized around those elements rather than around a generic compliance checklist.

The technical documentation should also make the DoC traceable. A reviewer should be able to match the declaration to the product identity, test reports, standards list, drawings, software or firmware versions that affect conformity, user information, installation instructions, and any Article 10(10) restriction information.

- Include a general product description with external features, marking, internal layout, and compliance-relevant software or firmware versions.
- Include design and manufacturing drawings, circuit or sub-assembly schemes, and explanations needed to understand operation.
- List harmonised standards applied in full or in part; where they were not used, record the other technical specifications and solutions used to meet Article 3.
- Attach design calculations, examinations, test reports, and the copy of the EU declaration of conformity.
- Add the EU-type examination certificate and annexes if Annex III was used, plus the Article 10(2) and Article 10(10) explanations required by Annex V.

## CE marking and notified-body evidence

For RED products, the CE marking evidence should show that the mark was affixed before the radio equipment was placed on the market, was visible, legible, and indelible on the equipment or data plate where possible, and was also visible and legible on the packaging.

Not every RED file has the same notified-body evidence. If harmonised standards are not applied, only partly applied, or do not exist for Article 3(2) or Article 3(3) requirements, Article 17 points to EU-type examination followed by conformity to type or full quality assurance for those essential requirements. If Annex IV full quality assurance is used, the notified-body identification number follows the CE marking.

- Keep artwork or photos showing the CE mark on the product or data plate and on packaging.
- Record any reason the CE mark could not be placed on the product itself because of the nature of the radio equipment.
- Keep the notified-body name, number, intervention description, and certificate details where Annex VI item 7 applies.
- If Annex IV applies, verify that the notified-body identification number is placed after the CE marking.
- Keep the manufacturer or authorised representative approval record for the declaration and CE marking release.

## When related RED records belong in the same file

Some RED products need additional records alongside the DoC and CE marking file because the declaration and technical documentation must cover the actual equipment configuration placed on the market.

For equipment covered by the common-charger amendment, keep the charging-capability specifications, compatible charging-device information, required label, and pictogram records with the same product file. For radio equipment covered by the Article 3(3)(d), (e), or (f) cybersecurity delegated act, keep the evidence showing how those activated essential requirements were assessed.

- For common-charger products, keep USB Type-C, USB Power Delivery where applicable, label, pictogram, packaging, distance-selling, and instructions evidence.
- For internet-connected or otherwise covered cybersecurity products, map the product category to the activated Article 3(3) requirement and keep the assessment evidence with the technical file.
- For products with user-changeable compliance-relevant software, accessories, or components, describe them in the DoC and user information at a level that lets the user operate compliant equipment.
- For products with restrictions on putting into service or authorisation requirements, keep packaging and instruction evidence that identifies the relevant Member State or geographic area.
- Reopen the file when hardware, firmware, accessories, intended use, standards, notified-body certificates, labels, packaging, or market restrictions change.
