CE Marking for Electronic Products

Which directives apply, what goes into the technical file, how long it takes — and the cybersecurity requirement that now catches connected products by surprise.

Quick answer: which CE directives apply?

Most consumer electronics sold in the EU need the EMC Directive (2014/30/EU) and the Low Voltage Directive (2014/35/EU). Products with a radio interface additionally fall under the Radio Equipment Directive (RED, 2014/53/EU), which since 2025 also enforces cybersecurity and privacy requirements through EN 18031. Most products containing hazardous substances also need RoHS (2011/65/EU).

The three pillars of CE compliance

EMC Directive

Emissions: EN 55032 (multimedia) or EN 55014. Immunity: EN 55035 / EN 55014-2. Demonstrates the device neither disturbs nor is disturbed by other equipment.

Low Voltage Directive

Electrical safety for 50–1000 V AC / 75–1500 V DC equipment, usually via EN 62368-1 (IT and AV) or EN 60335-1 (household appliances).

Radio Equipment Directive

RF spectrum use, EMC and safety for radio products, plus — since the delegated regulation — cybersecurity, privacy and fraud protection.

EN 18031: the requirement most exporters miss

From 1 August 2025, radio equipment placed on the EU market must meet the cybersecurity requirements of the RED delegated regulation, assessed against EN 18031 (three parts covering network protection, privacy protection and fraud protection). Products affected include Wi-Fi and Bluetooth devices, IoT hardware, smart home equipment, wearables and connected toys.

In practice this means manufacturers must document how the device prevents unauthorised network access, protects personal data and resists fraud — and keep that documentation in the technical file. It is a documentation and design review exercise as much as a test.

CE marking process and timeline

StepWhat happensTypical duration
1. Directive & standard mappingIdentify applicable directives and harmonised standards1–2 days
2. TestingEMC, safety and RF testing on production samples1–2 weeks
3. Technical fileAssemble risk assessment, BOM, schematics, manuals, declarations3–5 days
4. Declaration of ConformitySign the EU DoC and affix the CE mark1 day

Most projects complete in 3–5 weeks after samples arrive. Products needing a Notified Body opinion (such as certain RED Article 3.3 categories) take longer.

Frequently Asked Questions

Is CE marking mandatory for products made in China?

Yes. CE marking is a requirement of placing the product on the EU market, not of where it was manufactured. The manufacturer — or their authorised representative in the EU — must ensure conformity, sign the Declaration of Conformity and hold the technical file.

Can a Chinese manufacturer sign the EU Declaration of Conformity?

Yes, a manufacturer outside the EU can sign the DoC. They should be prepared to make the technical file available to market surveillance authorities, and many appoint an EU authorised representative to hold that documentation locally.

What is the difference between CE and FCC certification?

CE is a self-declaration system for the EU: the manufacturer declares conformity against EU directives, usually without a government filing. FCC authorisation for the US involves testing to FCC rules, and for radio products a filing with a Telecommunication Certification Body that issues an FCC ID.

Do I need a Notified Body for CE marking?

Usually not. Most consumer electronics can be self-declared under EMC and LVD. Certain categories — including some RED Article 3.3 product classes — require involvement of a Notified Body, and some manufacturers choose one voluntarily to strengthen their file.

What is EN 18031 and does it apply to my product?

EN 18031 is the harmonised standard supporting the cybersecurity requirements of the Radio Equipment Directive that became applicable on 1 August 2025. It applies to radio equipment that can connect to a network or process personal data — including Wi-Fi, Bluetooth and IoT devices.

How long is a CE technical file valid?

There is no expiry date, but the file must be kept current. Any change to hardware, firmware affecting RF or safety, or applicable standards should trigger a review, and the file must be retained for at least ten years after the last product is placed on the market.
