The CE Mark Complete Guide

The CE mark is the "passport" for products entering the EU market. This article systematically explains how to determine applicability, the directive system, conformity assessment routes and the role of Notified Bodies — helping you understand the whole CE certification process from scratch.

What is the CE Mark?

CE (Conformité Européenne) is the EU's mandatory conformity mark. Affixing the CE mark means the manufacturer declares that the product meets all applicable EU requirements and may be legally circulated freely across the EU / EEA's 30 countries.

Key point: The CE mark is not a "quality certification", but a "safety/compliance declaration". It is not a certificate issued by a body; it is the manufacturer's legal commitment that the product is compliant. Consequences of non-compliance include products being withdrawn, goods seized at customs, and fines (up to 4-6% of global annual turnover in the worst cases).

Which Directives Apply to Your Product?

Different product types fall under different CE directives. A single product may be subject to several directives at once — for example, a Bluetooth speaker needs RED + RoHS, and one with a power adapter also needs EMC + LVD.

Directive / Regulation	Short name	Scope	Typical products
2014/53/EU	RED	Wireless equipment	Bluetooth earphones, WiFi cameras, smart watches
2014/30/EU	EMC	Electromagnetic compatibility of electronic equipment	All electronic products containing circuitry
2014/35/EU	LVD	Safety of mains-powered equipment	Power adapters, chargers, home appliances
2011/65/EU	RoHS	Restriction of hazardous substances	All electronic products (almost full coverage)
2006/42/EC	MD	Machinery safety	Power tools, industrial equipment
(EU) 2025/40	PPWR	Packaging waste	All products with packaging
(EU) 2023/1542	Battery Regulation	Batteries and products containing batteries	All products containing lithium batteries

Conformity Assessment Route: Self-Declaration vs Notified Body

CE certification does not always require a third-party body. Depending on the directive and the product risk level, there are different "conformity assessment modules".

Module A: Internal production control (self-declaration)

The manufacturer completes all testing and evaluation itself and signs its own DoC. Suitable for most low-risk electronic products (e.g. an ordinary Bluetooth speaker doing RED + EMC). No NB involvement required.

Condition: the manufacturer must be able to carry out a full conformity assessment (own in-house laboratory or commissioning third-party testing).

Modules B+C / Module H: NB involvement

Requires a Notified Body to issue an EU-Type Examination Certificate. Applies to high-risk products:

Medical devices (MDR)
Certain wireless band equipment (RED Article 3.3)
Personal protective equipment (PPE)
Certain construction products (CPR)

Practical advice: Even where self-declaration is permitted, most exporters still choose third-party laboratory testing — not because it is mandatory, but because customers, platforms and customs want to see a "certificate". In this industry, "do you need an NB" and "do you need a test report" are two different questions.

How to Write a Declaration of Conformity (DoC)?

The EU Declaration of Conformity is the core document of the CE mark. Under ISO/IEC 17050-1, a valid DoC must include the following elements:

No.	Element	Description
1	Product identification	Model, batch number, serial number (enough to uniquely identify the product)
2	Manufacturer information	Company name, address, authorised representative
3	DoC issuer	The manufacturer or its EU authorised representative (single responsible party)
4	Declaration subject	Explicitly states which directives/regulations the product complies with
5	Referenced standards	Lists the harmonised standards applied (e.g. EN 300 328, EN 301 489)
6	NB information	If applicable, the NB name, number and certificate number
7	Signature details	Signatory's name, position, date, signature

Common mistake: Many DoCs only state "complies with CE requirements" without listing the specific directives and standards — this is legally invalid. Customs and market surveillance authorities have the right to require a complete DoC.

CE Mark Certification Process (6 steps)

Determine applicable directives

Confirm all applicable CE directives based on product type, function and intended use

Confirm the conformity assessment route

Self-declaration or NB involvement? Confirm whether an NB is needed

Complete compliance testing

Carry out the necessary testing to harmonised standards (in-house or via a third party)

Compile technical documentation

Includes product description, design drawings, test reports, risk assessment, etc.

Sign the DoC

The manufacturer signs the EU Declaration of Conformity

Affix the CE mark

Affix the CE mark to the product body / nameplate / packaging and archive for inspection

FAQs

How much does CE certification cost?

It depends on the product and directive combination. A simple Bluetooth speaker (RED + RoHS + EMC) is around CNY 8,000-15,000; adding a power adapter with LVD adds roughly CNY 2,000-4,000. If NB involvement is required (e.g. medical devices), the cost can multiply several times over or more.

Does the CE mark need to be printed on the product?

Preferably on the product body or nameplate. If the product is too small to bear it, it can be printed on the packaging and accompanying documents. The CE mark height must not be less than 5mm.

How long is CE certification valid?

As long as the product design is unchanged and the applicable standards are not updated, CE certification remains valid indefinitely. If standards are updated, you must re-assess whether supplementary testing is needed.

What is the relationship between CE and the "EU representative"?

Non-EU manufacturers must appoint an Authorised Representative within the EU to keep the DoC and technical documentation and to cooperate with market surveillance inspections. A CE mark without an EU representative is non-compliant.

Can the CE mark still be used after Brexit?

The UK has introduced the UKCA mark but in 2025 announced it will recognise the CE mark indefinitely. The CE mark is still accepted on most products in the UK, but we recommend also monitoring UKCA requirements.
