EU product compliance and market access
CE marking explained: a practical route from product scope to EU market compliance
Determine whether CE marking applies, identify every relevant EU legal act, select the correct conformity-assessment route, build defensible technical documentation, sign the EU Declaration of Conformity and maintain compliance after the product reaches the market.
- CE marking vs CE certification
- Technical file and Declaration of Conformity
- Harmonised standards and notified bodies
Start with the legal meaning
What CE marking is—and what it is not
CE marking is a regulatory conformity marking used under specified EU product legislation. It communicates the manufacturer’s declaration that the product satisfies every applicable requirement that provides for the mark.
A manufacturer declaration
Affixing CE means the manufacturer takes responsibility for identifying the applicable law, completing the conformity assessment and supporting the claim with evidence.
Limited to covered products
CE marking is compulsory only where EU legislation expressly requires it. It is prohibited on products outside that legal framework.
Not an EU approval
No central EU authority generally grants permission to use CE. The correct route may be self-assessment or may require an appropriately designated notified body.
A lifecycle obligation
Technical documentation, declarations, production conformity, complaints, changes and corrective actions remain relevant after the mark is affixed.
Do not start with the CE logo. Start with product qualification, intended use, applicable legislation and the economic operator placing the finished product on the market under its name or trademark.
2026 transition watch
Three current legal changes that can alter a CE marking project
Product legislation changes independently by sector. A checklist copied from a previous product or an older declaration can miss transition dates, digital requirements and changed assessment routes.
Machinery Regulation
Regulation (EU) 2023/1230 replaces the Machinery Directive framework from its application date. Projects launching near the transition need a documented legal-date strategy.
Construction Products Regulation
Regulation (EU) 2024/3110 introduces a new CPR framework with transition provisions. Construction products require sector-specific declarations, systems and harmonised technical specifications.
Toy Safety Regulation
Regulation (EU) 2025/2509 entered into force in 2026 and starts applying after the transition period, including a digital product passport framework for toys.
Use the law that applies when the product is placed on the market. Transition planning should consider design freeze, testing, certificates, production, stock, declarations and the intended market-placement date.
Interactive scope triage
Does your product probably fall within CE marking legislation?
Select the closest product group for an orientation route. This tool is not a legal classification and cannot evaluate exclusions, mixed products, intended use, accessories, components or national requirements.
A product can fall under several EU acts simultaneously—for example safety, EMC, radio, hazardous-substance and ecodesign rules.
End-to-end compliance workflow
How to obtain CE marking: a 10-step manufacturer roadmap
The order can vary by sector, but every reliable project needs a traceable route from legal scope to design evidence, declaration, production conformity and post-market action.
Define the product and responsible business
Document intended use, users, foreseeable misuse, variants, accessories, software, packaging and the party placing the finished product on the market.
- Identify manufacturer, brand owner and supply-chain roles.
- Decide whether a component, partly completed product or final assembly is being supplied.
Identify every applicable EU legal act
Check definitions, scope, exclusions, essential requirements, transitional provisions and other product rules that apply simultaneously.
- Do not select one familiar Directive and stop.
- Record the legal version and market-placement date.
Map essential requirements
Create a requirements matrix connecting each legal requirement to design controls, tests, calculations, standards, instructions and evidence.
- Mark applicable, not applicable and partially applicable items.
- Give a reason for every conclusion.
Select standards and technical specifications
Search legislation-specific OJEU publications, then verify exact EN references, amendments, restrictions and cessation dates.
- Use product-specific standards before generic ones where appropriate.
- Document alternative solutions and deviations.
Choose the conformity-assessment route
Determine whether internal production control is permitted or a notified body is required by class, category, module, standards route or risk.
- Verify notified-body designation in NANDO.
- Separate testing, certification and notified-body roles.
Assess risks and design for compliance
Translate requirements into engineering controls, protective measures, warnings, software controls, production specifications and acceptance criteria.
- Risk assessment is more than a test report.
- Residual risks must align with labels and instructions.
Test, calculate and verify
Use representative samples, valid methods, correct configurations and competent laboratories. Resolve failures through controlled redesign and retesting.
- Record sample identity and worst-case rationale.
- Check supplier evidence and safety-critical components.
Compile the technical documentation
Build a coherent file showing product design, manufacture, risks, applicable law, standards, testing, instructions, production controls and assessment records.
- Keep it available to authorities.
- Maintain revision and change control.
Sign the correct declaration and affix CE
Use the model required by the applicable legislation, identify every relevant EU act, and affix the official mark only after the assessment is complete.
- Use the notified-body number only where required.
- Ensure labels, traceability and languages are correct.
Maintain conformity after launch
Control series production, supplier changes, complaints, incidents, software updates, standards changes, corrective actions, withdrawals and recalls.
- Reassess changes that may affect conformity.
- Keep the declaration and file current.
High-intent search question
CE marking vs “CE certification”: use the right legal language
Businesses often search for a CE certificate, but the legal route is product conformity assessment followed by the manufacturer’s declaration and CE marking.
What a valid CE project can include
- A manufacturer-led conformity assessment where the law permits it.
- Test reports, calculations and risk evidence from competent sources.
- A notified-body certificate when the applicable procedure requires one.
- A complete technical file and signed EU Declaration of Conformity.
- Correct CE marking, traceability information and user documentation.
What should trigger caution
- A seller offering a generic “CE certificate” without identifying the legal act and module.
- A certificate from a body not designated in NANDO for the product and task.
- A document issued without product identification, tests or technical evidence.
- A promise that one report or one standard makes every legal requirement compliant.
- A logo licence or voluntary certificate presented as permission to affix CE.
The CE symbol itself is free. Costs arise from engineering, standards, testing, documentation, translations, notified-body services, quality controls, corrective action and ongoing compliance.
Common CE-marking sectors
EU product legislation frequently involved in CE marking
This is an orientation list, not a complete legal determination. Product definitions, exclusions, intended use and simultaneous legislation decide the actual route.
Electrical equipment
Low Voltage Directive 2014/35/EU
Electrical equipment within defined voltage limits. Product scope, exclusions and other simultaneous legislation still need checking.
Electromagnetic compatibility
EMC Directive 2014/30/EU
Equipment that can generate or be affected by electromagnetic disturbance. Apparatus and fixed installations have different obligations.
Radio and wireless products
Radio Equipment Directive 2014/53/EU
Radio spectrum, EMC, safety and—where applicable—cybersecurity or privacy requirements can overlap.
Machinery
Directive 2006/42/EC / Regulation (EU) 2023/1230
The current Directive remains central during the transition. The Machinery Regulation applies from 14 January 2027.
Toys
Directive 2009/48/EC / Regulation (EU) 2025/2509
The new Toy Safety Regulation entered into force in 2026 but applies from 1 August 2030 after a transition period.
Personal protective equipment
Regulation (EU) 2016/425
The conformity route depends on PPE category. Category III products involve ongoing notified-body participation.
Medical devices
Regulation (EU) 2017/745
Device classification, clinical evidence, quality-system and notified-body requirements vary substantially by device and route.
In vitro diagnostics
Regulation (EU) 2017/746
IVD classification and performance-evaluation obligations determine the applicable conformity assessment and evidence.
Construction products
Regulation (EU) 2024/3110
The new CPR applies in stages and uses a sector-specific performance and conformity framework. Check transition provisions and harmonised technical specifications.
Pressure equipment
Pressure Equipment Directive 2014/68/EU
Classification by pressure, volume, fluid group and equipment type influences the conformity-assessment module.
Gas appliances
Regulation (EU) 2016/426
Gas-burning appliances and fittings follow product-specific essential requirements and conformity-assessment routes.
Measuring instruments
Directive 2014/32/EU
Legal metrology requirements apply to listed instrument categories and specified measuring functions.
Supply-chain responsibility
Who is responsible: manufacturer, importer, distributor, representative or notified body?
CE marking responsibility cannot be outsourced by simply purchasing a test report. Each economic operator has defined duties, and the party marketing the finished product under its own name can become the manufacturer.
Manufacturer or brand owner
Owns product conformity, the assessment route, technical documentation, declaration, CE marking, series-production control and corrective action—even when design or manufacturing is outsourced.
Authorised representative
Performs only tasks included in a written mandate. The representative does not automatically assume product design responsibility and cannot sign away the manufacturer’s core obligations.
Importer
Checks that the manufacturer completed the applicable procedure, that required documents and markings exist, and that traceability and storage conditions are maintained. Rebranding or significant modification can trigger manufacturer duties.
Distributor
Acts with due care, verifies obvious compliance information, preserves conditions and cooperates with authorities. A distributor that rebrands or modifies the product may become the manufacturer.
EU responsible economic operator
For products covered by Article 4 of Regulation (EU) 2019/1020, an established EU operator must perform specified compliance and authority-cooperation tasks.
Notified body and laboratory
A notified body performs only tasks within its official designation. A laboratory generates test evidence within its competence. Neither automatically owns the manufacturer’s complete legal assessment.
Evidence architecture
What belongs in CE technical documentation?
The exact contents come from the applicable legislation. A defensible file should let a competent reviewer understand the product, reproduce the conformity logic and trace each conclusion to controlled evidence.
Product identity and intended use
Models, variants, serial or batch logic, users, environment, functions, accessories, software, claims and foreseeable misuse.
Applicable legislation and requirements matrix
Legal acts, versions, scope conclusions, essential requirements and a mapping to evidence, standards or justified alternatives.
Design and manufacturing information
Drawings, schematics, architecture, specifications, bill of materials, critical components, processes and quality controls.
Risk assessment
Hazards, foreseeable use and misuse, risk estimation, controls, verification, residual risks and connection to warnings and instructions.
Standards and technical solutions
Exact reference, edition, amendment, clauses applied, OJEU status, deviations and evidence for requirements not covered by standards.
Tests, calculations and inspections
Plans, sample identity, configurations, methods, competence, results, failures, corrective action, retesting and worst-case rationale.
Supplier and component evidence
Declarations, certificates, specifications, incoming controls and analysis of interfaces and combined-product risks.
Labels, instructions and languages
Product marking, traceability, warnings, installation, operation, maintenance, disposal and translations required in target markets.
Conformity-assessment records
Module decisions, notified-body applications, certificates, audit records, quality-system evidence and conditions of validity.
Declaration and change history
Signed declaration, approval authority, release date, revision history, change assessments and post-market corrective actions.
Series-production controls
Manufacturing specifications, inspection, supplier control, calibration, nonconformity, CAPA and release criteria ensuring continued conformity.
Retention and authority access
Record owner, storage, security, language, retrieval and the retention period specified in the relevant product legislation.
A folder full of reports is not automatically a technical file. The documentation needs a controlled narrative connecting product scope, law, risks, standards, evidence and the released configuration.
Legal declaration
EU Declaration of Conformity: content, signature and control
The declaration is signed only after the applicable conformity assessment is complete. By signing it, the manufacturer assumes responsibility for the product’s compliance with the identified EU law.
| Declaration element | What to include | Frequent mistake |
|---|---|---|
| Manufacturer | Legal name and full business address; authorised representative where the model requires it. | Using a trading name that cannot be matched to the responsible legal entity. |
| Product identification | Type, model, batch, serial or other unambiguous identification; an image can support traceability. | Using a marketing family name that covers products with different compliance evidence. |
| Responsibility statement | The statement required by the applicable model confirming sole manufacturer responsibility. | Replacing legal text with a vague statement that the product is “certified”. |
| EU legislation | All applicable directives and regulations, with correct titles or references. | Listing only the law associated with the main product function. |
| Standards and specifications | Exact references and editions actually applied; distinguish full and partial application where necessary. | Listing a family without parts, editions or evidence that the standard was used. |
| Notified body | Name, number, procedure and certificate details where required by the applicable model. | Listing a test laboratory as a notified body or adding a number from an unrelated certificate. |
| Signature | Place, date, name, function and signature of a person legally authorised to represent the manufacturer. | Unsigned templates, copied signatures or a signatory without authority. |
| Document control | Version, issue date and a process for review when product, law, standards or business details change. | Treating the declaration as permanent after redesign, supplier changes or new legislation. |
One product can be subject to several CE-marking acts. The applicable legislation may require one consolidated EU Declaration of Conformity covering all of them, while certain sectors use different declarations such as a Declaration of Performance or Declaration of Incorporation.
The final visible step
How to affix the CE marking correctly
Use the official Commission artwork and the placement rules in the applicable legislation. Do not recreate the mark with an ordinary font or alter its proportions.
- Visible, legible and indelible. The mark should normally be affixed to the product before it is placed on the market.
- Use official proportions. If enlarged or reduced, preserve the proportions in Annex II to Regulation (EC) No 765/2008.
- Minimum height is normally 5 mm. Specific product legislation can provide another rule.
- Use packaging or accompanying documents only where permitted. The product legislation and the nature of the product decide the fallback.
- Add a notified-body number only where required. The four-digit number is not a general quality badge.
- Do not add confusing marks. Other markings must not mislead users about the meaning, visibility or legibility of CE.
- Check sector-specific additions. Construction products, machinery, medical devices and other sectors can have additional marking and information rules.
Examples, not a universal checklist
Standards families often researched for CE marking projects
Confirm the exact product scope, part, edition, amendments and legislation-specific OJEU citation. A standard used for one product cannot be copied blindly to another.
Machinery risk assessment
General machinery design principles, hazard identification, risk estimation and risk reduction. It does not replace product-specific standards or the legal assessment.

Common CE marking mistakes that undermine market access
Detailed answers
CE marking requirements and certification FAQs
These answers provide general orientation. Product-specific conclusions require the current legal text, applicable standards, evidence and market-placement facts.
Is CE marking the same as CE certification?
No. CE marking is the manufacturer’s legal declaration that the product complies with all applicable EU legislation requiring the mark. There is no central EU authority that sells a general CE certificate. Some conformity routes require a notified body, but many allow manufacturer self-assessment. Voluntary certificates cannot replace the legally required procedure.
Which products require CE marking?
Only products within the scope of EU legislation that explicitly requires CE marking. Common examples include toys, certain electrical and radio products, machinery, PPE, medical devices, IVDs, pressure equipment, gas appliances and measuring instruments. The scope and exclusions in each legal act must be checked. Products outside CE-marking legislation must not carry the mark.
Can I self-certify my product?
Where the applicable legislation permits internal production control or another manufacturer-led module, the manufacturer can perform the conformity assessment without a notified body. ‘Self-certification’ does not mean no testing or documentation; the manufacturer still needs a defensible risk assessment, evidence, technical documentation, production controls and a signed declaration.
When is a notified body required?
Only when the relevant legislation and conformity-assessment route require third-party involvement. The trigger may depend on product class, category, risk, standards route or selected module. Verify the body’s exact designation and scope in NANDO. A laboratory or ISO certification body is not automatically a notified body.
Does CE marking prove that the EU approved the product?
No. The CE mark is not an EU approval, quality award or origin mark. It is the manufacturer’s declaration of conformity. Market-surveillance authorities can still inspect, restrict, withdraw or recall a product if evidence is incomplete or the product is unsafe or non-compliant.
Are harmonised standards mandatory?
They are generally voluntary. Correct use of an OJEU-cited harmonised standard can provide presumption of conformity for the requirements and conditions covered by the citation. A manufacturer may use another technical solution but must explain and evidence how the mandatory legal requirements are met.
Must testing be performed by an accredited laboratory?
Not in every CE-marking route. Some legislation or assessment procedures require a notified body or specified testing arrangements. In other cases, accreditation is not legally mandatory but can strengthen confidence in competence and traceability. The technical file should explain why the chosen laboratory, method, specimen and report are suitable.
How long must the technical file be retained?
Many EU product regimes require technical documentation and the declaration to be retained for 10 years after the product is placed on the market, but some sector legislation specifies another period or a different starting point. Always follow the applicable legal act rather than applying a universal retention rule.
What must the EU Declaration of Conformity contain?
The exact model depends on the legislation, but it commonly includes manufacturer identification, product identification, a responsibility statement, applicable EU acts, relevant standards or specifications, notified-body details where applicable, place and date, and the name, function and signature of an authorised signatory. It must be kept current.
Can I CE mark a final product made from CE-marked components?
Not automatically. Component declarations and reports can support the assessment, but the manufacturer placing the final product on the market remains responsible for the complete product, interfaces, foreseeable use, combined risks, applicable legislation and the final declaration.
Can an importer or distributor become the manufacturer?
Yes in certain situations. An operator that places a product on the market under its own name or trademark, or modifies it in a way that may affect compliance, can assume manufacturer obligations. The exact consequence depends on the applicable product legislation and the nature of the change.
Does CE marking expire?
The mark does not have a fixed renewal date, but the conformity claim relates to the product as placed on the market. Product changes, new risks, changed suppliers, updated legislation, changed standards or a different conformity route can require review, additional testing, documentation updates or a new assessment.
Where must the CE mark be placed?
Preferably on the product. If that is not possible or warranted because of the product’s nature, the applicable legislation may allow placement on packaging and accompanying documents. It must be visible, legible and indelible. The standard minimum height is 5 mm unless sector rules provide otherwise, and the official proportions must be preserved.
What does the four-digit number next to CE mean?
It identifies a notified body where the applicable legislation and assessment procedure require its number to accompany the CE mark, commonly when the body is involved in the production-control phase. Do not add a number merely because a laboratory issued a report or a body issued a voluntary certificate.
What happens if a CE-marked product is unsafe?
The business must investigate and take appropriate corrective action. Depending on the product and risk, this can include stopping sales, correcting labels or instructions, withdrawal, recall and notification to authorities through the applicable official channel. CE marking does not remove post-market duties or shield a product from enforcement.
How much does CE marking cost and how long does it take?
There is no fee for the CE symbol itself and no universal timetable. Cost and duration depend on product complexity, redesign, standards, test programme, samples, documentation maturity, translations, notified-body involvement, corrective actions and production controls. A credible plan should show assumptions, dependencies and decision gates.
