EU CE-RED Certification Guide for Wireless Products

Want your wireless products to smoothly enter the European market? CE-RED certification is not an option, but a mandatory threshold that must be crossed. This guide will help you avoid the pitfalls along the certification journey.

In the European market, any device capable of transmitting or receiving radio signals must comply with the requirements of the red directive (2014/53/EU). Officially implemented on June 13, 2016, this regulation replaced the former R&TTE Directive and has become the mandatory access requirement for wireless products to enter the EU.

Is Your Product within the Certification Scope?

If your product can communicate or locate via radio waves, it most likely requires RED certification.

1．Daily wireless devices: Consumer products including but not limited to Bluetooth headsets, smart watches, wireless speakers, smart home controllers, and remote-controlled toys.

2．Professional communication devices: Professional equipment such as walkie-talkies, wireless microphones, vehicle-mounted radio devices, and industrial remote controllers.

3．Network connection devices: IoT devices like Wi-Fi routers, ZigBee gateways, LoRa modules, and NB-IoT terminals.

4．Special category products: Special-purpose equipment including satellite communication terminals, radar devices, and aviation radios.

Key Technical Requirements for Certification

RED certification is not a single test, but a complete technical compliance assessment system.

1．Electromagnetic compatibility (EMC) test: Your device must not only resist external electromagnetic interference but also avoid becoming an interference source that affects the normal operation of other devices. Relevant testing standards mainly refer to the EN 301 489 series.

2．RF performance verification: Devices operating in different frequency bands must meet the corresponding parameter requirements for transmit power, frequency tolerance, bandwidth, etc. For example, devices working in the 2.4GHz frequency band must comply with the specific provisions of the EN 300 328 standard.

3．Electrical safety assurance: Regardless of the power supply method, the device must pass a safety assessment to ensure no electric shock, fire, or other risks to users. EN 62368-1 is a commonly used assessment standard.

4．Human radiation evaluation: Devices used close to the human body (such as mobile phones and wearable devices) require special evaluation of the impact of their electromagnetic radiation on human health, usually through sar testing in accordance with the en 62479 or en 62311 standards.

5．New cybersecurity requirements: Starting from August 2025, all relevant devices must also meet new cybersecurity requirements, including network anti-interference capabilities, user privacy protection, and fraud prevention functions.

Step-by-Step Analysis of the Certification Process

Preparation and Planning (1–2 weeks)

1．Determine the specific standards and test items applicable to the product.

2．Select a certification body with corresponding qualifications (note: certain high-risk products must be certified by an EU Notified Body).

3．Prepare initial technical documentation and test samples.

Testing and Evaluation (3–6 weeks)

1．Provide prototypes required for testing: usually including regular commercial prototypes and special fixed-frequency prototypes.

2．Conduct comprehensive testing at a qualified laboratory: covering EMC, RF, safety, and other aspects.

3．Timely address issues identified during testing and make design adjustments if necessary.

Review and Certification Issuance (2–4 weeks)

1．Submit complete technical documentation and test reports.

2．The certification body conducts a final review.

3．Obtain the certification certificate and sign the Declaration of Conformity.

Practical Strategies to Meet New Cybersecurity Requirements

The supplementary requirements issued by the EU in early 2022 will officially take effect on August 1, 2025, which means:

1．Incorporate cybersecurity into the design phase: Security features should be embedded from the initial stage of product design, rather than being added as a remedy afterward.

2．Choose certified modules: Using wireless modules that have already obtained cybersecurity certification can significantly reduCE certification difficulty.

3．Prepare comprehensive documentation: Detailed security design documents, risk assessment reports, and descriptions of response measures need to be provided.

4．Monitor updates to harmonized standards: Timely follow the latest versions and requirement changes of the en 18031 series standards.

Key Materials Required for Certification

Technical Documents

1．Circuit design description (attached with signal flow diagram)

2．Detailed circuit schematic diagram (with key parameters marked)

3．RF parameter specification sheet

Evidential Documents

1．Existing certification certificates (e.g., module certification)

2．Draft Declaration of Conformity

3．Test reports

User Documentation

1．Multilingual user manual (must include compliance marking instructions)

2．Product label design drawing (with reserved space for the ce mark)

Common Misunderstandings and Countermeasures

My product has low power, so it does not need certification.

In fact, regardless of power output, any product with wireless functionality requires certification.

With module certification, the complete machine does not need further certification.

Module certification can reduce the number of test items, but the complete machine still needs to undergo corresponding evaluation and certification.

One certification is valid permanently.

In the event of major product changes, re-evaluation or even re-certification is required.

EU supervision of wireless products is constantly being strengthened. In addition to the requirements of the RED Directive, the upcoming EU Cyber Resilience Act (CRA) will further enhance cybersecurity requirements throughout the product lifecycle.
