# How to sell consumer electronics in the EU: CE marking overview
Short answer: Selling electronic consumer goods in the EU means proving, before the first unit ships, that each product meets every applicable piece of EU harmonisation legislation; the CE marking is the visible result of that work. The process runs from mapping every applicable directive and regulation, through choosing the conformity assessment route and testing against harmonised EN standards, to building the technical file and EU Declaration of Conformity, then marking, labelling and monitoring the product.
Key facts
- By affixing the CE marking, the manufacturer declares the product meets all legal requirements for CE marking and can be sold throughout the EEA.
- CE marking is compulsory only for products covered by specific EU harmonisation legislation; it is forbidden on other products, and it is not an EU approval.
- A typical mains-powered smart device can fall under several acts at once: EMC, electrical safety, radio equipment, RoHS, and ecodesign or energy labelling.
- Most consumer electronics use manufacturer self-assessment against harmonised EN standards; radio equipment and higher-risk categories may require a notified body.
- The manufacturer must carry out the conformity assessment, set up the technical file, issue the EU Declaration of Conformity, and affix the CE marking.
- Non-EU manufacturers need an EU-based economic operator (authorised representative or importer) able to present documentation to authorities.
- WEEE registration is required in each member state of sale, and post-market duties apply under the Market Surveillance Regulation.
1. Map every applicable directive and regulation
CE marking is not a single certificate; it is the visible outcome of compliance with every applicable piece of EU harmonisation legislation. For consumer electronics, the candidate list typically includes the Electromagnetic Compatibility Directive 2014/30/EU, the Low Voltage Directive 2014/35/EU for electrical safety, the Radio Equipment Directive 2014/53/EU if the product has Bluetooth, Wi-Fi or any other radio function, the RoHS Directive 2011/65/EU on hazardous substance restrictions, and ecodesign or energy-labelling rules for relevant product types.
Work through the product's features systematically: mains-powered, battery-powered, radio transmitter, software-defined functions, chargers and accessories in the box. Each feature maps to candidate legislation. Missing one act is the most common compliance failure in electronics, because teams focus on the "main" directive (often EMC or radio) and overlook RoHS, ecodesign, or the battery rules for the accessory in the box. List every applicable act in writing before you start testing; the list becomes the table of contents for the technical file.
2. Identify the conformity assessment route
Each directive defines the conformity assessment procedures available for the products it covers, following the modules of the New Legislative Framework (from Module A, internal production control, to Module H, full quality assurance). Most consumer electronics use Module A: the manufacturer assesses the product itself against harmonised standards, without a notified body. Radio equipment may require a notified body for certain conformity assessment procedures, particularly where harmonised standards do not fully cover the essential requirements. Higher-risk categories outside consumer electronics (medical devices, ATEX equipment) routinely require notified bodies, but ordinary consumer electronics rarely do.
The route is defined per directive, so check each one, not just the main one. Document the chosen module for each applicable act in the technical file; if a market surveillance authority asks why no notified body was involved, the answer is the module analysis, not an assumption.
3. Test against harmonised standards
Harmonised standards are EN standards cited in the Official Journal of the EU for a given directive. Applying them correctly gives a presumption of conformity with the essential requirements they cover: the legal burden shifts, and the authority must show the product is non-compliant rather than you having to prove compliance from first principles. If you use alternative technical solutions instead, your technical file must demonstrate equivalence, which is a heavier burden and invites closer scrutiny.
Have an accredited laboratory test to the current harmonised EN standards for each applicable directive: emissions and immunity for EMC, electrical safety testing for the Low Voltage Directive, radio performance and spectrum efficiency for the Radio Equipment Directive, and material analysis for RoHS. Keep the test reports: they are the backbone of the technical documentation and the first thing market surveillance authorities ask for. Test the product as sold, including firmware version, accessories in the box, and any user-replaceable modules, because the assessment covers the product in its placed-on-the-market configuration.
4. Build the technical file and the EU Declaration of Conformity
The technical documentation file compiles everything that demonstrates compliance: a general description of the product, design and manufacturing drawings and explanations, the list of harmonised standards applied (or the alternative solutions with justification), the risk assessment, test reports, and the EU Declaration of Conformity. The file must be kept available to authorities, typically for ten years after the last unit is placed on the market, depending on the applicable legislation.
The EU Declaration of Conformity is the manufacturer's formal legal statement: it identifies the product, lists the EU legislation complied with, references the standards or specifications used, and names the signatory. It is a legal document, not marketing copy; the person signing it should have the authority and the evidence to stand behind it.
Non-EU manufacturers need an EU-based economic operator, an authorised representative or an importer, who can present the declaration and the technical documentation to authorities on request. Align in writing on who holds the file, how authority requests are handled, and what happens to the documents if the commercial relationship ends.
5. Mark, label, and monitor after sale
Affix the CE marking according to the graphic rules: the prescribed proportions, visible, legible and indelible on the product or, where the product's nature requires, on its packaging and accompanying documents. Add traceability labelling: model designation, batch or serial number, and the manufacturer's name and address (and the importer's where applicable). Include required instructions and safety information in the language of each member state of sale.
Then handle the parallel registrations. Register for WEEE in each member state where the product is sold, because WEEE producer registration is national, not EU-wide. Batteries in the product trigger battery producer obligations. After sale, the Market Surveillance Regulation (EU) 2019/1020 framework applies: maintain a process for handling consumer complaints, monitor for safety issues, keep traceability records, and be ready to take corrective action, including withdrawal or recall, and to cooperate with authorities.
| Step | Output | Owner | Typical pitfall |
|---|---|---|---|
| Map applicable legislation | Written list of directives/regulations | Manufacturer / regulatory lead | Missing RoHS, ecodesign, or battery rules |
| Choose assessment module | Module analysis per directive | Manufacturer | Assuming self-assessment where a notified body is required |
| Test to harmonised standards | Accredited test reports | Test laboratory | Testing a prototype that differs from the shipped product |
| Compile technical file | Complete documentation file | Manufacturer | Missing risk assessment or alternative-solution justification |
| Draw up the DoC | Signed EU Declaration of Conformity | Manufacturer signatory | Listing wrong legislation or outdated standards |
| Affix CE marking and labels | Marked product with traceability | Manufacturer | Wrong proportions; missing batch/serial |
| Register WEEE per member state | Registration numbers | Producer / authorised representative | Assuming one EU-wide registration |
| Post-market monitoring | Complaint process; corrective action readiness | Economic operators | No process until a safety issue appears |
Frequently asked questions
Does CE marking mean the EU approved my product?
No. CE marking is the manufacturer's declaration that the product meets all applicable legal requirements; it is not an approval by the EU or any authority, and it does not indicate the product's origin. Authorities verify compliance through market surveillance after products are on the market.
Can I self-certify, or do I need a notified body?
For most consumer electronics, the applicable directives allow self-assessment (Module A, internal production control) against harmonised standards. A notified body is required only where the specific directive and product category demand it, such as certain radio equipment assessment routes or higher-risk product categories. Check each applicable directive separately.
What is the difference between a harmonised standard and any other standard?
A harmonised standard is an EN standard cited in the Official Journal for a specific directive; applying it correctly confers a presumption of conformity with the essential requirements it covers. Other standards or technical solutions can be used, but the technical file must then demonstrate how they meet the essential requirements, which is a heavier evidentiary burden.
I manufacture outside the EU. Who presents documents to authorities?
An EU-based economic operator: your authorised representative or your importer, designated in writing. They must be able to produce the EU Declaration of Conformity and the technical documentation on a reasoned request from market surveillance authorities. Arrange this before the first shipment.
Do I need separate WEEE registration for each EU country?
Yes. WEEE producer registration is national. Selling an electronic product in Germany, France and the Netherlands means registering in each country's system (for example, with Stiftung EAR in Germany), usually through a local authorised representative.
What happens if a harmonised standard is updated?
Track the Official Journal citations for your directives. When a standard is superseded, there is typically a transition period; products assessed under the old version may need re-assessment for continued production. Build standards monitoring into the product's change-control process.
