Executive Summary
CE marking is a legal conformity marking used for products covered by specific European Union legislation. By affixing it, the manufacturer declares under its responsibility that the product meets all applicable EU legal requirements necessary for placing it on the market.
CE marking is not a general quality certificate, a sign that the product was made in Europe or evidence that every product has been independently tested by an authority. Some products can be assessed by the manufacturer. Others require the involvement of a notified body, depending on the product legislation and conformity-assessment route.
A compliant process starts by identifying all applicable legislation, defining the economic operators, assessing risks, selecting relevant standards, testing and evaluating the product, preparing technical documentation, signing the EU Declaration of Conformity and correctly affixing the CE marking.
This guide provides a complete practical framework for manufacturers, importers, distributors, private label brands and international suppliers placing CE-marked products on the European market.
| CORE PRINCIPLE CE marking is the visible result of a complete conformity process. The logo itself does not make a non-compliant product compliant. |
|---|
1. What Is CE Marking?
CE marking indicates that a product covered by relevant EU harmonisation legislation has been assessed and is declared to meet the applicable health, safety, environmental or other essential requirements.
It supports the free movement of covered products within the European Economic Area when all applicable legal conditions are met.
The manufacturer is normally the primary party responsible for the conformity process, including where design or production is outsourced.
| CE Marking Means | CE Marking Does Not Mean |
|---|---|
| Applicable EU requirements have been addressed | The product is superior in quality |
| The manufacturer accepts legal responsibility | An EU authority approved every product |
| Required conformity steps were completed | The product was manufactured in Europe |
| The product may be placed on the market if all other rules are met | One certificate covers every future variant or change |
2. Which Products Require CE Marking?
CE marking is required only where applicable EU legislation specifically requires it.
Common covered categories include machinery, electrical equipment, radio equipment, personal protective equipment, pressure equipment, medical devices, toys, measuring instruments and certain construction products.
Products outside CE-marking legislation may still be subject to general product safety, chemicals, packaging, environmental, labelling or sector-specific rules.
| Product Area | Examples of Relevant EU Rules |
|---|---|
| Machinery | Machinery legislation and related safety requirements |
| Electrical equipment | Low Voltage and EMC requirements |
| Radio products | Radio Equipment Directive |
| Medical devices | Medical Device and In Vitro Diagnostic frameworks |
| Personal protective equipment | PPE Regulation |
| Pressure equipment | Pressure Equipment Directive |
| Toys | Toy Safety Directive |
| Construction products | Construction Products Regulation |
3. Products That Must Not Carry CE Marking
A product should not carry the CE marking when no applicable legislation requires it.
Wrongly affixing the mark can mislead authorities and customers and may itself breach EU rules.
The company should document why CE marking is or is not applicable.
| WARNING Do not add CE marking as a general marketing symbol. First identify the exact legal basis that requires it. |
|---|
4. Identify All Applicable Legislation
A single product can fall under several EU legal acts at the same time.
For example, connected electrical equipment may involve electrical safety, electromagnetic compatibility, radio, hazardous substances, energy efficiency, cybersecurity and general product-safety obligations.
The manufacturer must comply with every applicable act before signing the Declaration of Conformity.
| Assessment Question | Example |
|---|---|
| What is the product and intended use? | Industrial controller for fixed machinery |
| Which technologies are included? | Mains voltage, radio module and software |
| Who will use it? | Professional, consumer or vulnerable user |
| Where will it be placed? | EU / EEA market and specific environment |
| Which hazards exist? | Electrical, mechanical, thermal, radio and cyber |
5. Define the Product and Intended Use
The product definition determines which legislation, standards and tests apply.
The manufacturer should define the model, variants, accessories, intended users, operating environment, foreseeable misuse, interfaces and limitations.
Vague intended use can create gaps in risk assessment and instructions.
| Product Definition Field | Required Detail |
|---|---|
| Model and variants | Exact products covered |
| Intended purpose | What the product is designed to do |
| Users | Consumer, professional or trained specialist |
| Environment | Indoor, outdoor, industrial, medical or explosive |
| Interfaces | Mechanical, electrical, radio and software connections |
| Limitations | Prohibited uses and operating boundaries |
6. Identify the Economic Operators
EU product rules assign obligations to manufacturers, authorised representatives, importers, distributors and fulfilment service providers.
The exact duties depend on the applicable legislation and supply-chain role.
A company selling under its own name or trademark may be treated as the manufacturer even when production is outsourced.
| Economic Operator | Typical Responsibility |
|---|---|
| Manufacturer | Design, conformity assessment, technical file, declaration and marking |
| Authorised representative | Performs specifically mandated tasks in the EU |
| Importer | Checks non-EU manufacturer compliance before placing product on the EU market |
| Distributor | Acts with due care and verifies required marking and information |
| Fulfilment service provider | May carry responsibilities where no other EU operator is established |
| BEST PRACTICE Map the real legal role of every company in the supply chain before contracts, labels and declarations are finalized. |
|---|
7. Manufacturer Responsibilities
The manufacturer remains responsible for ensuring conformity even when engineering, testing or production is outsourced.
Core obligations normally include identifying applicable rules, carrying out conformity assessment, preparing technical documentation, issuing the EU Declaration of Conformity, affixing CE marking and maintaining production conformity.
Product-specific legislation may add registration, post-market, incident or quality-system obligations.
8. Importer Responsibilities
An EU importer placing a product from a non-EU manufacturer on the market must verify that the manufacturer completed the required conformity process.
The importer should check the marking, declaration, technical-documentation availability, instructions, traceability and manufacturer identification.
Importer name and contact details may need to appear on the product, packaging or accompanying documentation according to the applicable rules.
| Importer Check | Evidence |
|---|---|
| Applicable conformity route completed | Declaration and certificates where required |
| CE marking correct | Product and packaging review |
| Technical file available | Manufacturer commitment and access |
| Traceability present | Model, batch, serial and operator details |
| Instructions supplied | Required language and safety information |
| Storage and transport controlled | No damage to conformity |
9. Distributor Responsibilities
Distributors must act with due care before making products available.
They should verify that required CE marking, traceability, instructions and economic-operator information are present. They should not supply a product they know or should reasonably suspect is non-compliant.
Storage and transport conditions must not compromise compliance.
10. Risk Assessment
Risk assessment is central to conformity assessment.
The manufacturer should identify hazards across the product lifecycle, estimate and evaluate risks, apply protective measures and document residual risks.
The analysis should consider normal use, foreseeable misuse, installation, maintenance, transport and disposal where relevant.
| Risk-Control Hierarchy | Example |
|---|---|
| Inherently safe design | Remove sharp edge or reduce voltage |
| Protective measures | Guard, enclosure or automatic shutdown |
| Information for use | Warning, instruction and training requirement |
| WARNING Warnings should not be used as a substitute for reasonably achievable safe design or protective measures. |
|---|
11. Essential Requirements
EU product legislation generally defines essential or fundamental requirements rather than prescribing every design detail.
The manufacturer must identify which requirements apply and demonstrate how each is satisfied.
A compliance matrix is a practical way to connect legal requirements with design evidence, standards, tests and technical-file documents.
| Compliance Matrix Field | Example |
|---|---|
| Legal requirement | Protection against electric shock |
| Applicability | Applies to mains-powered variants |
| Method | Design control and harmonised standard |
| Evidence | Test report and circuit analysis |
| Technical-file reference | Report section and drawing number |
12. Harmonised Standards
European harmonised standards are voluntary technical specifications whose references are published in the Official Journal of the European Union.
Correct application can provide a presumption of conformity with the legal requirements covered by the standard.
The manufacturer should verify the exact standard version, amendment, publication status and scope.
| Standards Check | Question |
|---|---|
| Reference published | Is the standard cited in the Official Journal? |
| Scope | Does it cover the exact product and use? |
| Version | Is the correct edition and amendment applied? |
| Coverage | Which essential requirements are addressed? |
| Gaps | What additional risk assessment or testing is needed? |
| BEST PRACTICE Do not rely only on a laboratory's standard list. Maintain your own controlled standards register and applicability review. |
|---|
13. When Standards Are Not Used
Use of harmonised standards is generally voluntary.
A manufacturer may use another technical solution, but it must demonstrate that the applicable legal requirements are met.
The technical justification and evidence may need to be more detailed because presumption of conformity is not available for uncovered requirements.
14. Conformity Assessment Routes
The applicable legislation defines the permitted conformity-assessment modules or procedures.
Some products allow internal production control by the manufacturer. Others require examination, audits, product testing or quality-system assessment by a notified body.
The required route may depend on product category, risk, standards used and classification.
| Route Type | Typical Structure |
|---|---|
| Self-assessment / internal control | Manufacturer evaluates and documents conformity |
| EU type examination | Notified body examines a representative product type |
| Production quality assurance | Notified body assesses the production quality system |
| Product verification | Notified body examines products or samples |
| Full quality assurance | Notified body assesses design and production system |
15. Notified Bodies
A notified body is an organisation designated by an EU country to perform specific conformity-assessment tasks under particular legislation.
Not every CE-marked product requires a notified body. The legislation and conformity route determine whether one is needed.
The manufacturer should verify the body's notification scope in the official NANDO database.
| Notified Body Check | Why It Matters |
|---|---|
| Correct legislation | Body must be notified for the applicable act |
| Correct product scope | Notification may be limited to certain categories |
| Correct assessment task | Body must cover the chosen module |
| Certificate validity | Status, conditions and product coverage |
| WARNING A generic laboratory report or ISO certificate is not automatically a notified-body conformity certificate. |
|---|
16. Testing and Evaluation
Testing should follow the applicable legal requirements, standards and risk assessment.
It may include safety, electromagnetic compatibility, radio, mechanical, chemical, environmental, performance, software or cybersecurity evaluation.
Reports should identify the exact product, configuration, samples, methods, results and deviations.
| Test Evidence | Quality Check |
|---|---|
| Product identity | Model, hardware and software version |
| Test method | Standard and clause |
| Sample configuration | Worst-case variant and accessories |
| Equipment | Calibration and laboratory competence |
| Results | Pass, fail, limits and observations |
| Deviations | Justification and effect on validity |
17. Technical Documentation
Technical documentation must demonstrate how the product complies.
It should be prepared before the product is placed on the market and kept available for market-surveillance authorities. A common retention period is ten years, unless the applicable legislation specifies otherwise.
The file may be electronic, but it must remain controlled, retrievable and understandable.
| Technical File Section | Typical Content |
|---|---|
| Product description | Models, intended use and variants |
| Design and manufacture | Drawings, BOM, schematics and process information |
| Legislation and standards | Applicability and version list |
| Risk assessment | Hazards, controls and residual risks |
| Calculations and tests | Reports, simulations and validation |
| Quality / production control | How ongoing conformity is maintained |
| Labels and instructions | Final user-facing information |
| Declaration and certificates | Signed declaration and notified-body documents |
18. EU Declaration of Conformity
The EU Declaration of Conformity is the manufacturer's formal legal statement that the product complies with the applicable legislation.
It should identify the manufacturer, product, legislation, standards and any notified body involved, and it must be signed by an authorised person.
Where several legal acts apply, one declaration can list them together where permitted.
| Declaration Field | Required Information |
|---|---|
| Manufacturer | Legal name and address |
| Product | Model, type, batch or serial identification |
| Responsibility statement | Declaration issued under sole responsibility |
| Legislation | All applicable EU acts |
| Standards | Applied harmonised standards or specifications |
| Notified body | Name, number and certificate where relevant |
| Signature | Place, date, name, function and signature |
19. Affixing the CE Marking
The CE marking should normally be affixed visibly, legibly and indelibly to the product or its data plate.
Where product size or nature prevents this, the applicable legislation may allow placement on packaging or accompanying documents.
The official proportions must be respected, and the minimum height is generally 5 mm unless product-specific legislation provides otherwise.
| Marking Rule | Practical Check |
|---|---|
| Visible | Can users and authorities find it easily? |
| Legible | Is size and contrast sufficient? |
| Indelible | Will it remain through normal use? |
| Correct proportions | Official graphic geometry used |
| Body number where required | Only when the notified body is involved as prescribed |
20. Other Marks and Labels
CE marking may appear alongside other mandatory or voluntary markings, provided they do not reduce its visibility or create confusion.
Examples may include WEEE, recycling, energy, hazardous-substance, radio, construction or sector-specific information.
The label should be reviewed as a complete legal deliverable.
21. Instructions and Safety Information
Products should be accompanied by the instructions and safety information required by the applicable legislation.
Language requirements depend on the countries where the product is made available.
Instructions should match the final product configuration and residual risks identified in the risk assessment.
| Instruction Area | Examples |
|---|---|
| Installation | Tools, environment and qualified-person requirements |
| Operation | Controls, limits and normal use |
| Safety | Warnings, PPE and prohibited use |
| Maintenance | Intervals, spare parts and isolation |
| Disposal | Environmental and hazardous-material information |
22. Traceability and Product Identification
Traceability helps authorities and companies identify affected products and economic operators.
Products should carry type, batch, serial or other identification as required. Manufacturer and importer contact details should be provided according to the applicable rules.
Traceability should connect market units to production and test records.
23. Production Conformity
A product that passed initial testing can become non-compliant if materials, suppliers, firmware, tooling or production controls change.
The manufacturer should maintain ongoing conformity through approved suppliers, controlled documents, inspections, calibration, training and change control.
Significant changes may require new risk assessment, testing, declaration updates or notified-body review.
| Change Trigger | Possible Action |
|---|---|
| Component substitution | Review safety, EMC, radio and material impact |
| New factory | Validate production controls and certificate scope |
| Software update | Assess function, safety and cybersecurity impact |
| New variant | Confirm worst-case testing and declaration coverage |
| Standard or law change | Review transition and update plan |
24. Private Label and Rebranding
A company placing a product on the market under its own name or trademark may assume manufacturer responsibilities.
It should not rely only on the original factory's CE mark. The private label company needs sufficient access to conformity evidence and clear control over the product, changes, labels and technical documentation.
Contracts should define document access, change notification, audit rights and post-market cooperation.
| WARNING Changing only the brand does not remove legal responsibility. Rebranding can change which company is treated as the manufacturer. |
|---|
25. Importing CE-Marked Products from Outside the EU
An importer should verify compliance before placing the product on the EU market.
A CE mark printed on a product or a supplier's informal 'CE certificate' is not sufficient evidence.
The importer should review the applicable legislation, declaration, tests, notified-body documents where required, labels, instructions and technical-documentation availability.
| Supplier Evidence | Importer Review |
|---|---|
| EU Declaration of Conformity | Correct entity, product, laws, standards and signature |
| Test reports | Exact product, version and valid methods |
| Certificates | Relevant body, scope and validity |
| Technical file index | Complete and accessible |
| Product labels | CE, traceability and economic-operator details |
| Change-control commitment | Supplier must notify material changes |
26. Market Surveillance
National market-surveillance authorities can inspect products, request technical documentation, test samples and require corrective action.
Authorities may restrict sales, order withdrawal or recall, or impose penalties where products are non-compliant or unsafe.
Companies should have a defined authority-response process.
| Authority Request | Company Response |
|---|---|
| Technical file | Provide controlled, relevant documentation |
| Sample or test | Preserve chain of custody and investigate |
| Sales / distribution data | Identify affected batches and customers |
| Corrective action | Contain, correct, withdraw or recall as required |
27. Non-Compliant and Unsafe Products
When a company has reason to believe a product is non-compliant, it should assess the risk and take proportionate corrective action.
Actions can include stopping shipment, quarantining stock, correcting documentation, modifying the product, withdrawing units or recalling products.
Authorities may need to be informed where the product presents a risk.
28. Product Changes and Regulatory Monitoring
CE compliance is not a one-time project.
Manufacturers should monitor legal changes, new harmonised-standard references, withdrawn standards, product incidents, supplier changes and new technologies.
A periodic compliance review should confirm that the technical file and declaration remain current.
| Monitoring Source | Purpose |
|---|---|
| Official Journal / EU Commission | Legislation and harmonised standards |
| Product authority notices | Enforcement trends and guidance |
| Notified body | Certificate conditions and regulatory updates |
| Supplier change notices | Material and process changes |
| Complaints / incidents | Real-world safety signals |
29. Cybersecurity and Connected Products
Connected products may be subject to cybersecurity requirements in addition to traditional product-safety legislation.
The applicable obligations and transition dates depend on the product and legal act. Manufacturers should assess secure design, vulnerability handling, software updates and incident reporting early in development.
Cybersecurity evidence should be integrated into the product's risk management and technical documentation where applicable.
| BEST PRACTICE Do not wait until final testing to address cybersecurity. Security architecture, update support and vulnerability processes should be designed from the beginning. |
|---|

33. Practical Example: Imported Industrial Controller
A European distributor planned to import a connected industrial controller from an Asian manufacturer.
The supplier provided a CE logo, an EMC report and a short declaration. The distributor's review found that the declaration omitted radio legislation, the test report covered a different power supply and no cybersecurity or foreseeable-misuse analysis was included.
The parties created an applicability matrix, repeated worst-case electrical and EMC tests, completed radio assessment, updated the risk file and corrected the instructions and labels. The importer also added its required EU contact details.
The product was released only after the technical file and Declaration of Conformity matched the final hardware and software configuration.
