CE Marking for Electronics: Requirements, Process, Testing & Compliance Guide (2026)

CE marking is a mandatory conformity mark required for most electronics products sold in the European Union. It indicates that a product complies with EU regulations related to safety, electromagnetic compatibility, and environmental protection.

Manufacturers must ensure their products meet the requirements of applicable EU directives before placing them on the market. These directives commonly include the EMC Directive, Low Voltage Directive, and RoHS Directive.

Without CE marking, electronics products may be blocked at EU customs, removed from the market, or subject to regulatory penalties.

This guide explains how CE marking works for electronics manufacturers, including applicable directives, testing requirements, technical documentation, compliance costs, and the steps required to legally sell products in the European Union.

CE Marking for Electronics - Quick Summary

• CE marking is required for most electronics products sold in the EU.
• Manufacturers are responsible for ensuring compliance with EU regulations.
• Electronics products typically fall under EMC, Low Voltage, and RoHS directives.
• Compliance requires testing, technical documentation, and a Declaration of Conformity.
• Once compliance is demonstrated, manufacturers can affix the CE marking and sell the product in the EU.

What Is CE Marking?

CE marking is a conformity mark that indicates a product complies with applicable European Union legislation.

For electronics manufacturers, CE marking confirms that a product meets EU requirements related to:

• electrical safety
• electromagnetic compatibility
• hazardous substance restrictions

Unlike certification systems that require government approval, CE marking is typically based on manufacturer self-declaration.

The manufacturer must demonstrate compliance with applicable directives and maintain technical documentation supporting this claim.

Once the CE mark is affixed, the product can be freely sold across all countries in the European Economic Area (EEA).

Who Needs CE Marking?

CE marking applies to any manufacturer placing regulated products on the European Union market.

This includes:

• EU-based manufacturers
• non-EU manufacturers exporting to the EU
• importers placing products on the EU market
• private label brands selling electronics under their own brand

Even if products are manufactured outside the EU, manufacturers must ensure compliance before the product enters the European market.

For non-EU companies, this often requires appointing an EU Authorized Representative.

Which Electronics Products Require CE Marking?

Most electronic and electrical products must carry CE marking before being placed on the EU market.

Examples include:

• consumer electronics
• IoT devices and smart home products
• electronic accessories
• household appliances
• industrial electronics
• power supplies and chargers

In general, if a product contains electrical or electronic components and falls within the scope of EU directives, CE marking will be required.

Manufacturers must determine which directives apply based on the product's design, voltage range, and functionality.

EU Directives That Apply to Electronics

Electronics products may fall under several EU directives and regulations.

The most common ones include the following.

EMC Directive (2014/30/EU)

The Electromagnetic Compatibility Directive ensures that electronic devices do not generate excessive electromagnetic interference and remain immune to interference from other devices.

Most electronics products must undergo EMC testing to demonstrate compliance.

For a detailed explanation, see our guide on EMC testing standards for CE marking.

Low Voltage Directive (2014/35/EU)

The Low Voltage Directive applies to electrical equipment operating between:

• 50–1000V AC
• 75–1500V DC

This directive ensures that electrical products are safe and protect users from hazards such as electric shock or fire.

RoHS Directive (2011/65/EU)

The RoHS Directive restricts hazardous substances in electrical and electronic equipment.

Restricted substances include:

• lead
• mercury
• cadmium
• hexavalent chromium

Manufacturers must ensure components remain below the allowed concentration limits.

You can learn more in our guide on RoHS exemptions for electronics manufacturers.

Radio Equipment Directive (RED)

Products with wireless functionality such as Bluetooth or Wi-Fi must comply with the Radio Equipment Directive.

This directive covers requirements related to:

• radio spectrum usage
• electromagnetic compatibility
• electrical safety

CE Marking Process for Electronics

The CE marking process consists of several steps that manufacturers must complete before placing a product on the EU market.

1 Identify applicable directives

Manufacturers must determine which EU directives and harmonized standards apply to their product.

This step defines the technical requirements the product must meet.

2 Conduct product testing

Testing verifies that the product meets the relevant standards.

Electronics products commonly require testing such as:

• electromagnetic emissions testing
• immunity testing
• electrical safety testing

Manufacturers often work with accredited laboratories.

See our guide on how to choose an EMC testing lab.

3 Prepare technical documentation

Manufacturers must create a technical file demonstrating compliance with applicable EU regulations.

Technical documentation typically includes:

• product description
• design drawings
• bill of materials
• risk assessment
• test reports
• applied standards

Authorities may request this documentation during market surveillance.

4 Issue the EU Declaration of Conformity

The Declaration of Conformity (DoC) is a legal document confirming that the product complies with all applicable EU directives.

It must include:

• manufacturer identification
• product identification
• applicable directives
• harmonized standards used
• signature of the authorized person

You can see a template in our Declaration of Conformity guide.

5 Affix the CE marking

Once compliance has been verified and documentation completed, the manufacturer may affix the CE mark.

The CE marking must be:

• visible
• legible
• permanently affixed

It can appear on the product, packaging, or documentation depending on the product design.

EMC Testing Requirements

For most electronics products, EMC testing is one of the core requirements for CE compliance.

Testing verifies that the device:

• does not generate excessive electromagnetic interference
• remains immune to interference from other equipment

Typical EMC tests include:

• radiated emissions
• conducted emissions
• immunity testing

Understanding the difference between interference and compatibility is important. See our article on EMI vs EMC testing.

If a product fails EMC testing, manufacturers may need to redesign circuits, shielding, or grounding systems.

Our article on common EMC test failures and how to fix them explains typical issues.

Technical Documentation for CE Compliance

Technical documentation demonstrates that the product complies with EU regulations.

Manufacturers must maintain this documentation for several years after the product is placed on the market.

Typical documentation includes:

• product design information
• risk assessment
• compliance test reports
• manufacturing process documentation
• Declaration of Conformity

Incomplete documentation is one of the most common causes of customs delays and regulatory investigations.

How Much Does CE Marking Cost?

CE marking costs depend on several factors including:

• product complexity
• number of applicable directives
• testing requirements
• documentation preparation

For simple electronics products, compliance costs may be relatively low.

More complex devices requiring multiple test campaigns may incur higher compliance costs.

For a detailed breakdown, see our guide on CE marking costs for electronics products.

CE Mark vs UL vs FCC

Manufacturers selling products internationally often encounter multiple certification schemes.

Examples include:

• CE marking (European Union)
• UL certification (United States safety certification)
• FCC certification (United States radio regulations)

Although testing methods may overlap, these certifications are independent regulatory frameworks.

Manufacturers selling products globally may need to comply with several systems simultaneously.

See our comparison of CE Mark vs UL vs FCC certifications.

CE Marking Requirements for Electronics Manufacturers
