CE Marking: The Complete Guide
CE marking is how a manufacturer declares that a product meets the EU health, safety, and environmental requirements that apply to it — and the precondition for placing many products on the European market. This guide covers what CE marking actually means, which products need it, who is responsible, how it differs from a “CE certificate” and a Declaration of Conformity, the six steps to CE mark a product, what must appear on the product, and the documentation you have to keep.
What is CE marking?
CE marking (from the French Conformité Européenne, “European Conformity”) is a marking by which a manufacturer declares that a product complies with the EU legislation that applies to it, so the product can move freely on the market of the European Economic Area (EEA) — the EU plus Norway, Iceland and Liechtenstein — without facing different national rules in each country.
The key word is declaration. By affixing the CE marking, the manufacturer takes legal responsibility for the product’s conformity. It is a statement that says, in effect: “We have checked this product against the rules that apply to it, and it complies.” The general principles are set out in Regulation (EC) No 765/2008; the sector-specific directives and regulations decide which products must carry the mark and how conformity is assessed.
CE marking is mandatory only for products that fall under one or more EU directives or regulations that provide for it — for example machinery, electrical and electronic equipment, personal protective equipment, pressure equipment, medical devices, and toys. Products not covered by any such legislation must not carry a CE marking.
What the CE mark is not
A few common misconceptions are worth clearing up, because they drive most of the confusion around CE compliance:
- It is not a quality mark. CE marking is about meeting legal minimum requirements for safety and conformity — not about a product being well made or high quality.
- It is not issued by an authority. For most products, no government body or agency hands out the CE mark. The manufacturer applies it themselves after assessing conformity.
- It is not a certificate. The mark is a symbol; the evidence behind it is the technical file and the signed EU Declaration of Conformity. “CE marking is not a certification but a declaration” is the single most useful sentence to remember.
- It is not proof of where a product was made. CE marking has nothing to do with country of origin.
Which products need CE marking?
CE marking applies only where a specific piece of EU legislation requires it. The product groups covered include, among others:
- Machinery (Machinery Directive / Machinery Regulation).
- Electrical equipment within certain voltage limits (Low Voltage Directive).
- Electronic equipment that must not cause or be disrupted by interference (EMC Directive).
- Personal protective equipment (PPE Regulation).
- Pressure equipment (PED) and simple pressure vessels.
- Medical devices, toys, radio equipment, gas appliances, lifts, equipment for explosive atmospheres (ATEX), construction products, and more.
If a product falls under several of these at once — say, a machine with electrical and radio components — it must meet the requirements of every applicable directive before it can be CE marked. Conversely, product groups governed by other regimes (for example many chemicals, foods, cosmetics and textiles) are not CE marked at all.
Who is responsible for CE marking?
EU legislation places obligations on each “economic operator” in the supply chain, but the weight sits with the manufacturer:
- The manufacturer carries out (or commissions) the conformity assessment, compiles the technical file, signs the EU Declaration of Conformity, and affixes the CE marking. This applies whether the manufacturer is inside or outside the EU.
- An authorised representative established in the EU can be appointed by a non-EU manufacturer to keep the DoC and technical documentation available and to deal with authorities — but cannot take over the design and production obligations.
- The importer who places a non-EU product on the EU market must verify that the manufacturer has done the assessment and drawn up the documentation, must put its own name and address on the product, and must keep a copy of the DoC available.
- The distributor must act with due care: checking that the product carries the CE marking and is accompanied by the required documents before making it available.
That responsibility does not end at the point of sale. The documentation behind the CE mark has to be kept and produced if a market surveillance authority asks — in practice for years after the product ships.
CE marking vs a “CE certificate” vs a Declaration of Conformity
This is the single most common source of confusion, so it is worth stating plainly. For the majority of products, there is no “CE certificate.” The manufacturer self-assesses conformity and the key legal document is the EU Declaration of Conformity (DoC) — a signed statement that the product meets the applicable directives, listing the standards applied and the responsible person.
For higher-risk products, the legislation requires an independent Notified Body to be involved in the conformity assessment. In those cases the Notified Body issues a certificate (for example an EU-type examination certificate), and its identification number appears next to the CE marking. The Declaration of Conformity is still required — the Notified Body certificate supports it rather than replacing it.
So: the CE marking is the visible symbol on the product, the Declaration of Conformity is the legal document behind it, and a certificate exists only where a Notified Body is required. The dedicated guide — CE Marking vs Declaration of Conformity — works through the distinction in detail, including exactly what a Declaration of Conformity must contain.
The role of harmonised standards
EU legislation sets out the essential requirements a product must meet, but not the technical detail of how to meet them. That is the job of harmonised standards — standards whose references are published in the Official Journal of the EU.
Applying the relevant harmonised standard is voluntary, but it carries a powerful benefit: a product built to it enjoys a presumption of conformity with the essential requirements the standard covers. In practice this is the route most manufacturers take, because it turns an open-ended legal obligation into a concrete, testable specification.
How to CE mark a product (six steps)
The CE marking process follows the same six steps across most product groups:
1. Identify the applicable directive(s) and regulation(s). Determine which EU legislation covers your product — there may be more than one.
2. Determine the conformity assessment route. Establish whether you may self-assess, or whether a Notified Body must be involved based on the product’s risk class.
3. Assess and test conformity. Verify the product against the essential requirements, ideally via the relevant harmonised standards, and record the results.
4. Compile the technical documentation. Assemble the technical file — design, risk assessment, test reports, and the evidence that the product conforms.
5. Draw up and sign the EU Declaration of Conformity. Issue the DoC, listing the product, the legislation and standards applied, and the responsible person.
6. Affix the CE marking. Apply the CE marking (and any Notified Body number) to the product, following the rules on form and visibility.
After marking, the obligation continues: the technical documentation and Declaration of Conformity must be kept available for market surveillance authorities — typically for ten years after the product is placed on the market.

What the CE mark looks like — and what must be on the product
The CE marking has a fixed graphic form: the two letters in the official proportions, normally at least 5 mm high, affixed visibly, legibly and indelibly to the product or its data plate. Where the product’s size or nature makes that impossible, the marking goes on the packaging and the accompanying documents instead. If a Notified Body was involved in the production-control phase, its four-digit number follows the CE marking.
Alongside the mark, the legislation requires the manufacturer’s name and address, a type, batch or serial number that identifies the product, the importer’s details for imported products, and any instructions and safety information in the language of the country of sale. Nothing may be affixed that could mislead about the meaning or form of the CE marking. The CE marking requirements article lists what must be shown on the product in full.
CE marking and your documentation
CE marking does not end when the product ships. Declarations of Conformity, technical files, test reports, and any Notified Body certificates have to be retained and produced on request — and when you build products from certified components, you also depend on your suppliers’ DoCs and certificates.
This is where certificate management does the heavy lifting: store each Declaration of Conformity and certificate against the product record it belongs to, track the expiry of any Notified Body certificates with expiration tracking, and collect component DoCs from suppliers through supplier collaboration instead of by email. For the wider context, see the certificate management guide.
CE marking and UKCA in Great Britain
Since the UK left the EU, Great Britain (England, Scotland, Wales) has its own conformity marking, UKCA, alongside the EU’s CE marking. The two cover broadly equivalent ground but are legally distinct regimes.
The practical position has shifted several times, and UK government policy on how long CE marking remains accepted in Great Britain — and for which product groups — has continued to evolve. Northern Ireland operates under separate arrangements again. Because this is the most fast-moving part of the picture, confirm the current rules for your specific product group with up-to-date UK and EU guidance before relying on them.
