EMC and radio equipment: EU RED overview

# EMC and radio equipment: EU RED overview

Directive 2014/53/EU, the Radio Equipment Directive, covers products that intentionally emit or receive radio waves: Bluetooth, Wi-Fi, cellular, NFC and IoT devices. Three requirements apply to all radio equipment: health and safety protection, electromagnetic compatibility, and efficient use of radio spectrum. Delegated acts add category-specific duties, including cybersecurity requirements in force from 1 August 2025 and the common USB-C charger.

Key facts

• The RED has applied since 13 June 2016, replacing the earlier R&TTE Directive; it covers radio equipment, meaning products that intentionally emit or receive radio waves for communication or radiodetermination.
• Article 3 sets three essential requirements for all radio equipment: health and safety protection, electromagnetic compatibility, and efficient use of the radio spectrum to avoid harmful interference.
• Article 3(3) lists additional requirements that only become operative when a delegated act names the product categories: so far only points (d), (e) and (f), on network security, personal data safeguards and fraud protection, have been activated.
• Delegated Regulation (EU) 2022/30 activates those cybersecurity requirements for internet-connected radio equipment, childcare equipment, toys and wearables, applicable from 1 August 2025.
• Directive (EU) 2022/2380 amended the RED to require a common USB-C charging receptacle: applicable from 28 December 2024 for listed device categories, and from 28 April 2026 for laptops.
• Conformity assessment ranges from internal production control to EU-type examination by a notified body, depending on whether harmonised standards are fully applied.

1. Scope: what counts as radio equipment

The directive defines radio equipment as an electrical or electronic product that intentionally emits or receives radio waves for the purpose of radio communication or radiodetermination. In practice this covers Bluetooth headsets and speakers, Wi-Fi routers and smart-home devices, cellular phones and modules, NFC payment terminals, and the radio modules inside IoT products. A product that only incidentally emits electromagnetic radiation without intentional radio communication falls under the EMC Directive instead; a product with any intentional radio function falls under the RED, and the EMC Directive's essential requirements are then covered through the RED's own EMC essential requirement.

Certain equipment is excluded or subject to special regimes: radio equipment used exclusively for public security, defence and state security, and amateur radio equipment not placed on the market, sit outside the directive. Marine equipment and aviation equipment have their own sector regimes that interact with the RED. The first scoping question for any wireless product is therefore whether it intentionally transmits or receives radio waves, and the answer decides the entire conformity route.

2. The three essential requirements

Article 3(1)(a) requires protection of the health and safety of persons, domestic animals and property, including the safety objectives of the Low Voltage Directive. Article 3(1)(b) requires an adequate level of electromagnetic compatibility as set out in the EMC Directive. Article 3(2) requires that radio equipment be constructed so that it both effectively uses and supports the efficient use of radio spectrum, in order to avoid harmful interference.

These three apply to all radio equipment unconditionally. Harmonised standards cited in the Official Journal give a presumption of conformity for the requirements they cover; where no harmonised standard exists or is fully applied, the manufacturer must demonstrate compliance with the essential requirements directly, typically through a notified body's assessment. Radio performance testing is specialised: use laboratories with the right accreditation and the right frequency-band expertise, because spectrum requirements differ by band, power class and member-state implementation.

3. Article 3(3) and the delegated acts: cybersecurity becomes binding

Article 3(3) lists nine further essential requirements, points (a) to (i), but none of them applies to any product until the Commission adopts a delegated act naming the categories concerned. The Commission has activated points (d), (e) and (f) through Delegated Regulation (EU) 2022/30: radio equipment must not harm the network or misuse network resources, must incorporate safeguards for personal data and privacy, and must support features protecting against fraud, with application to internet-connected radio equipment and to childcare, toy and wearable categories.

These cybersecurity essential requirements apply from 1 August 2025, after a one-year extension by Delegated Regulation (EU) 2023/2444 to allow standards work to mature. Harmonised standards EN 18031-1, -2 and -3:2024 have been cited in the Official Journal with restrictions, giving a route to presumption of conformity for the products and clauses the Commission accepted. From 1 August 2025, in-scope equipment placed on the market must meet these requirements as a condition of CE marking.

The trajectory beyond that date points to the Cyber Resilience Act, which will absorb the cybersecurity ground currently covered by the RED delegated act when it reaches full application. Until then, the RED cybersecurity requirements are the binding regime for connected radio equipment, and they should be treated as current law, not as a preview.

4. The common charger: USB-C by delegated design

Directive (EU) 2022/2380 amended the RED to harmonise charging interfaces for listed categories of radio equipment. Devices must incorporate a USB Type-C receptacle, support USB Power Delivery for faster charging where applicable, and be offered with the option to buy the device without a charger. Packaging and documentation must carry pictograms and information on charging capabilities so consumers can match devices with chargers.

The rules apply from 28 December 2024 for the listed categories, handheld mobile phones, tablets, digital cameras, headphones, headsets, handheld videogame consoles, portable speakers, e-readers, keyboards, mice, portable navigation systems and earbuds, and from 28 April 2026 for laptops. For importers and brands, the charger interface is now a design constraint with a hard date: products in scope must be engineered around USB-C, and packaging artwork must carry the required information.

5. Conformity assessment routes

The RED's conformity assessment follows the familiar New Legislative Framework modules. Where the manufacturer applies harmonised standards in full for the applicable essential requirements, internal production control with the manufacturer's own assessment is available. Where harmonised standards are not applied, are only partly applied, or do not exist for a requirement, the route runs through a notified body: EU-type examination followed by conformity to type, or full quality assurance.

In practice, most mainstream wireless products can use internal production control against the cited standards for radio, EMC and safety, but the cybersecurity requirements and novel radio technologies push more products toward notified-body involvement. Choose the route per essential requirement, document the choice, and keep the assessment evidence with the technical file. Notified-body capacity for radio assessment is finite, so plan lead times into product schedules.

6. Technical documentation, declaration and labelling

The technical documentation must cover the product's radio characteristics alongside the usual design, manufacturing and test evidence, and it must identify the harmonised standards applied or the solutions adopted for each essential requirement. The EU declaration of conformity references the RED together with every other applicable directive or regulation, such as RoHS, ecodesign and, for machinery with radio functions, the Machinery Regulation.

Labelling must allow traceability: the manufacturer's name and contact address, and the importer's where applicable, plus type, batch or serial identification. Certain categories face additional information duties, such as the charging pictograms and the geographic-use information for equipment subject to restrictions on putting into service in some member states. Registration duties for specific categories, and information obligations toward users on intended use and restrictions, complete the picture.

7. Keeping current: a directive that keeps being amended

The RED is one of the most frequently amended product directives. Delegated acts under Article 3(3) can add requirements for new categories; the common charger showed how quickly a delegated design rule can reshape product lines; and the cybersecurity requirements will migrate to the Cyber Resilience Act in due course. Treat RED compliance as a maintained process: subscribe to Commission updates, track the Official Journal citations of harmonised standards, and review the conformity assessment route whenever a new delegated act touches the product category.

FAQs

Does a product with only Bluetooth Low Energy fall under the RED?

Yes. Intentional emission or reception of radio waves for communication brings the product into the RED's scope, regardless of the radio technology or power level. Low-power does not mean out of scope.

We apply harmonised standards in full. Do we still need a notified body?

For the RED's core essential requirements, internal production control is available when harmonised standards are applied in full. A notified body is needed where standards are not fully applied, do not exist for a requirement, or the applicable module requires it.

Do the cybersecurity requirements apply to our existing models?

They apply to in-scope equipment placed on the market from 1 August 2025. Products already placed before that date are not retroactively caught, but any new placement from the date must comply.

Is USB-C required for all electronic devices?

The common-charger rules apply to the listed categories of radio equipment in Annex Ia of the amended RED, from 28 December 2024, with laptops from 28 April 2026. Check the category list against the product rather than assuming.

How do the RED cybersecurity rules relate to the Cyber Resilience Act?

The RED delegated act is the binding cybersecurity regime for in-scope radio equipment now. The Cyber Resilience Act will absorb that ground at its full application, at which point radio equipment's cybersecurity assessment moves to the CRA while the RED continues to govern spectrum use and EMC.

Where do we check the current harmonised standards?

The Commission's harmonised standards pages and the Official Journal citations, including Implementing Decision (EU) 2025/138 for the EN 18031 series, show what is cited and with what restrictions. Confirm before claiming presumption of conformity.
