The CE Marking Certification Process: A Step-by-Step Guide for Manufacturers
The CE Marking Certification Process: A Step-by-Step Guide for Manufacturers
CE marking is one of the most misunderstood requirements in EU product regulation. Many manufacturers know they need it — but few have a clear picture of what the full process actually involves, in what order, and who is responsible for each step.
This guide sets out the CE marking certification process in chronological order, from the moment you determine that CE marking applies to your product through to the moment you affix the mark and maintain compliance over time. It is designed for manufacturers, product managers, and anyone responsible for getting a product onto the European market.
What Is CE Marking and Who Needs It?
CE marking is a declaration by the manufacturer that a product meets the essential requirements of the applicable EU legislation. It is not a quality mark, a safety guarantee issued by a third party, or a certification in the traditional sense. It is a legal obligation and a manufacturer’s own declaration of conformity with EU law.
CE marking is required for most product categories sold within the European Economic Area (EEA), including machinery, electrical equipment, radio devices, toys, construction products, medical devices, and many others. If your product falls within the scope of one or more EU directives or regulations that require CE marking, you cannot legally place it on the EU market without it.
A full overview of the main CE marking frameworks currently in force — including recent regulatory updates — is available on the CE Marking page.
Step 1 — Identify the Applicable Directives and Regulations
The first and most critical step is determining which EU legislation applies to your product. A single product can fall under multiple directives or regulations simultaneously — for example, a wireless industrial machine may be subject to the Machinery Regulation, the Radio Equipment Directive, and the EMC Directive at the same time.
The applicable legislation depends on the nature of the product, its intended use, and its technical characteristics. Common frameworks include:
- Machinery Regulation (EU) 2023/1230 — industrial and consumer machinery
- Low Voltage Directive (LVD) 2014/35/EU — electrical equipment
- Radio Equipment Directive (RED) 2014/53/EU — wireless and radio devices
- Electromagnetic Compatibility Directive (EMC) 2014/30/EU — electrical and electronic equipment
- Toy Safety Regulation (EU) 2025/2509 — toys for children under 14
- Construction Products Regulation (EU) 2024/3110 — construction materials and components
- General Product Safety Regulation (EU) 2023/988 — consumer products not covered by specific legislation
Getting this step wrong — either by missing an applicable directive or by applying the wrong one — invalidates everything that follows. When in doubt, this is the step at which professional guidance has the highest return on investment.
Step 2 — Identify the Applicable Harmonised Standards
Once you know which directives or regulations apply, the next step is identifying the relevant harmonised standards. These are technical standards published in the Official Journal of the European Union that, when applied, create a presumption of conformity with the essential requirements of the corresponding legislation.
Harmonised standards are developed by European standardisation bodies — primarily CEN, CENELEC, and ETSI — and their references are published by the European Commission. Using them is technically voluntary, but in practice they represent the most efficient route to compliance because they translate broad legislative requirements into specific, measurable technical criteria.
You can consult the official list of harmonised standards on the European Commission’s standards database.
Key questions at this stage:
- Is there a harmonised standard for my product type?
- Is the standard current, or has it been superseded?
- Does my product require compliance with multiple standards across different directives?
Step 3 — Determine the Conformity Assessment Procedure
Not all products follow the same conformity assessment route. EU legislation defines different modules — from self-declaration by the manufacturer to mandatory third-party assessment by a notified body — depending on the risk level and product category.
Self-declaration (Module A) is available for lower-risk products and most standard applications of common directives. The manufacturer conducts the assessment internally and takes full legal responsibility for the declaration.
Notified body involvement is mandatory when the product poses higher risks, when no harmonised standard exists, or when the applicable legislation explicitly requires it. Notified bodies are independent organisations designated by EU member states to carry out conformity assessments. Their involvement can range from type-examination to full quality system audits, depending on the applicable module.
Understanding which route applies to your product is essential before investing time and resources in documentation. A misjudgement here — for example, assuming self-declaration is sufficient when a notified body is required — can result in the entire process needing to be repeated.

Step 4 — Conduct the Risk Assessment
The risk assessment is the technical backbone of the CE marking process. It identifies the hazards associated with the product, evaluates the risks they present, and documents the measures taken to eliminate or reduce those risks to an acceptable level.
The methodology and depth of the risk assessment depend on the applicable legislation. For machinery, the process follows EN ISO 12100. For electrical equipment, it follows the relevant LVD standards. For toys, chemical and physical hazard assessments are required under specific protocols.
The risk assessment must be conducted before the technical documentation is finalised — not after. It informs design decisions, protective measures, and the selection of applicable standards. A risk assessment written retrospectively to justify an already-finalised product design is both less useful and less defensible under market surveillance scrutiny.
Key outputs of this step:
- A documented list of identified hazards
- An evaluation of risk for each hazard (severity Ă— probability)
- A record of risk reduction measures applied
- Residual risk conclusions
Step 5 — Build the Technical Documentation File
The technical documentation file — sometimes called the technical file or the design dossier — is the complete record that demonstrates how the product meets the essential requirements of the applicable legislation. It is not submitted to any authority under normal circumstances, but it must be available for inspection by market surveillance authorities for a defined period after placing the product on the market (typically 10 years).
The exact contents depend on the applicable directive or regulation, but a standard technical file includes:
- A general description of the product
- Design drawings, schematics, and component lists
- The risk assessment and its conclusions
- A list of applied harmonised standards
- Test reports and measurement results
- Instructions for use and safety information
- The EU Declaration of Conformity
The technical file must be maintained and updated whenever the product undergoes significant changes. It is the manufacturer’s legal responsibility — it cannot be outsourced in the sense of transferring that legal obligation, though its preparation can be supported by external specialists.
Step 6 — Issue the EU Declaration of Conformity
The EU Declaration of Conformity (DoC) is the formal document by which the manufacturer declares, under their sole responsibility, that the product meets all applicable EU requirements. It is a legally binding document.
The DoC must include:
- The manufacturer’s name and address
- A description of the product (name, model, serial number or batch)
- A statement of conformity with all applicable EU legislation
- References to the harmonised standards applied
- The place and date of issue
- The name and signature of the authorised signatory
The DoC must be made available to market surveillance authorities on request and, in many cases, must accompany the product or be accessible via a link or QR code. It must be kept for the same retention period as the technical file.
Step 7 — Affix the CE Marking
Once the conformity assessment is complete, the technical file is in order, and the Declaration of Conformity has been issued, the CE marking can be affixed to the product.
The CE mark must comply with specific formal requirements:
- Minimum height: 5 mm (unless the product’s size makes this impractical)
- Proportions: the mark must follow the prescribed geometric proportions — it cannot be freely scaled or distorted
- Placement: on the product itself, its packaging, or the accompanying documentation, depending on the product category
- Visibility: it must be visible, legible, and indelible
The CE mark must not be confused with other marks and must not be accompanied by any marking that could mislead users about its meaning. Affixing a CE mark to a product that does not genuinely comply with the applicable requirements is a criminal offence in most EU member states.
What Happens After CE Marking
CE marking is not a one-time event. Manufacturers have ongoing obligations once a product is on the market.
Market surveillance is conducted by national authorities across EU member states. They have the power to request the technical file, conduct inspections, and order product withdrawals or recalls if non-conformity is found. Penalties vary by member state and can include significant fines and criminal liability.
Product updates and changes may require a reassessment. If a product undergoes a substantial modification — in its design, intended use, or software — the manufacturer must evaluate whether the CE marking process needs to be repeated in whole or in part.
Regulatory changes can also affect existing products. As EU legislation is updated, harmonised standards are revised and new requirements enter into force. Manufacturers are responsible for monitoring these changes and ensuring their products remain compliant throughout their market lifecycle.
