CE certification for EU market entry

CE certification for European market entry: requirements, process and documentation. 

Anyone wishing to offer machinery, electrical appliances or other regulated products on the European market must comply with the relevant EU product legislation. For many product groups, this includes CE marking. It indicates that the manufacturer assumes responsibility for ensuring that its product complies with the applicable requirements.

However, the commonly used term “CE certification” does not describe a single approval procedure. Depending on the product, the manufacturer may assess conformity itself or must involve a notified body. Official approval or an externally issued CE certificate is not provided for every product.

Successful market entry therefore depends on following the correct sequence: classify the product, determine the requirements, demonstrate conformity and provide the necessary documentation and markings.

What does CE certification mean?

In practice, CE certification is often understood to mean the entire process leading to lawful CE marking. Technically, it is a conformity assessment under the applicable European legislation.

This involves checking and documenting whether a product meets the relevant requirements. These may concern, for example, electrical safety, mechanical hazards, electromagnetic compatibility or the restriction of certain hazardous substances.

Three terms should be distinguished:

A test report or certificate may form part of the supporting evidence. However, it does not automatically replace the full conformity assessment. CE is neither a general quality mark nor a mark of origin. Nor does the marking mean that an EU authority has tested and approved the product.

Which products require CE marking?

CE marking is mandatory only for products covered by the relevant EU harmonisation legislation. Typical areas include:

• Machinery and certain related products
• Electrical equipment
• Equipment subject to electromagnetic compatibility requirements
• Radio equipment
• Pressure equipment
• Personal protective equipment
• Medical devices
• Toys

The precise classification depends on the respective scopes and exemptions. Key factors include function, intended use, technical characteristics and intended users.

A product may be subject to several pieces of legislation at the same time. For an electrical device, for example, requirements relating to electrical safety, electromagnetic compatibility and certain constituent substances may be relevant.

For products outside the scope of the relevant legislation, CE marking must not be affixed voluntarily as a selling point. Furthermore, the absence of a CE marking requirement does not mean that a product is exempt from safety or labelling requirements.

For which countries is CE marking relevant?

CE marking is an instrument of the European single market. It is particularly relevant to the European Economic Area, which comprises the EU Member States as well as Iceland, Liechtenstein and Norway. The requirements also apply to products manufactured outside this economic area and subsequently offered there. The production location therefore does not exempt a manufacturer from the relevant obligations.

Nevertheless, the term “European market” should not be equated with an approval system that is identical everywhere. For destination countries outside the European Economic Area, the respective national regulations and any existing agreements must be examined separately.

Who is responsible for CE conformity?

Manufacturer: The manufacturer is responsible for the conformity of its product. This includes, in particular, carrying out the prescribed assessment, preparing the technical documentation and issuing the required declaration.

A company that has a product manufactured by another company and markets it under its own name or trademark may also be considered the manufacturer. Responsibility therefore does not depend solely on who actually carries out production.

Importers and distributors: Importers and distributors have their own verification and cooperation obligations. They must not rely solely on the presence of a CE mark on the product. Depending on their role, they must check, among other things, whether the required documentation, markings and manufacturer information are available.

Authorised representatives and service providers: An authorised representative may perform tasks delegated in writing. External technical consultants and testing laboratories may also support the manufacturer. However, engaging a service provider does not automatically transfer the manufacturer's entire responsibility.

For manufacturers outside the EU, it must also be clarified which economic operator established in the EU must be available to perform the respective prescribed tasks. The specific arrangements depend on the applicable regulations.

When is a notified body required?

Whether an independent body must be involved depends on the product group, the risk classification and the prescribed conformity assessment procedure. For numerous products, assessment under the manufacturer's responsibility is permitted. Other procedures require the involvement of a notified body, for example for certain tests, type assessments or the assessment of quality assurance.

A notified body is designated for specific tasks under specific EU legislation. Its authority therefore does not automatically extend to all products.

Before engaging a body, companies should check:

• Under which legislation the body is notified
• Which product groups its designation covers
• Which assessment procedures it is authorised to carry out
• Whether the service offered is suitable for the specific project

This information can be verified through the European NANDO information system. Accreditation alone does not replace the required notification.

CE conformity assessment process

Define the product and its intended use: The starting point is an unambiguous product description. This includes technical functions, variants, operating conditions and intended users. Interfaces and accessories are also relevant. Adding a radio module or modifying the control system at a later stage may trigger new requirements.

Determine the applicable legislation: The next step is to examine which directives and regulations apply. Their scope, exceptions and transitional provisions must all be taken into account. Incomplete identification of the applicable legislation may result in missing tests or a declaration of conformity that does not cover all relevant legal acts.

Select standards and a strategy for demonstrating conformity: Harmonised standards can facilitate the demonstration of conformity. Their application is generally voluntary. A presumption of conformity applies to the requirements covered by the respective standard, provided that the relevant reference has been published in the Official Journal of the EU and no corresponding restrictions preclude it.

The edition of the standard, its published reference and any transitional periods must therefore be checked. The latest published edition of a standard is not automatically already the applicable harmonised edition.

Assess risks and implement protective measures: The risk assessment links the product's technical characteristics to the statutory protection objectives. It should demonstrate in a traceable manner which hazards exist and how they are adequately reduced.

Depending on the product, mechanical, electrical, thermal or malfunction‑related risks, for example, may need to be considered. The assessment should be carried out during development so that necessary changes can be implemented in good time.

Carry out tests and compile supporting evidence: Test planning is based on the identified requirements. Depending on the product, measurements, calculations, functional tests or laboratory examinations may be appropriate.

Not every procedure requires an external testing laboratory. What matters is that the chosen approach is permitted and provides robust evidence. If a notified body is required, its involvement must be planned in good time.

Finalize documentation, declaration and marking: Following a successful assessment, the technical documentation is completed, the required declaration is issued and the marking is affixed. The manufacturer must also ensure that series‑produced products continue to conform to the assessed design.

What technical documentation is required?

The technical documentation must clearly demonstrate how the product meets the applicable requirements. Its precise content depends on the applicable legislation.

Typical components include:

• Product description and unambiguous identification
• Drawings, circuit diagrams and relevant design documentation
• Information on safety‑related components and materials
• Overview of the applicable legislation
• List of applied standards and other technical specifications
• Risk assessment and description of protective measures
• Calculations and test reports
• Operating instructions and safety information
• Draft markings
• Where applicable, documentation from a notified body

A collection of supplier certificates alone does not demonstrate the conformity of the finished product. The documentation must identify its specific design and assessment. The retention period is often ten years after the product is placed on the market. Any differing product‑specific requirements must be observed.

Declaration of conformity and CE marking

The declaration of conformity establishes the link between the product, the manufacturer and the applicable legislation. It must be drawn up in accordance with the relevant legal requirements and signed by a person authorized to do so. The product designation, model details and manufacturer details should match those on the nameplate, in the instructions and in the technical documentation. The language requirements of the countries where the product is sold must also be taken into account.

The CE mark is subject to requirements regarding design, visibility, legibility and durability. The product‑specific rules determine where it must be affixed. A notified body's identification number is added only if this is provided for in the relevant procedure.

Machinery update: Transition to the EU Machinery Regulation

For machinery projects, the date of placing on the market is particularly important. Machinery Regulation (EU) 2023/1230 generally applies from 20 January 2027 and replaces Machinery Directive 2006/42/EC.

Companies with projects extending beyond this date should check at an early stage which legal framework applies to the assessment of the specific machine. Receipt of an order or the start of production before the cut‑off date does not automatically mean that the previous Directive remains applicable when the machine is subsequently placed on the market.

The document names also differ: The Machinery Directive provides for an EC declaration of conformity for complete machinery, while the new Regulation provides for an EU declaration of conformity.

Practical example: Market entry with an electrical industrial device

A manufacturer outside the EU wishes to offer an electrical industrial device in Germany and France. Test reports for another market already exist for the device. The first step is to establish which European legislation applies to the specific design. The existing test reports are then reviewed to determine whether they cover the model being offered, the relevant requirements and suitable test methods.

In this example, the document review identifies three outstanding issues:

• The reports refer to an earlier power supply variant
• The instructions are available only in English
• The nameplate does not match the current model designation

Before market entry, the effects of the modified component are assessed, any necessary additional tests are carried out and the documentation is updated. The language versions are determined based on the requirements of the countries where the product is sold.

This illustrative example shows why existing test reports and a printed CE mark alone are no substitute for a complete market entry review.

Do EAC certificates replace the CE conformity assessment?

An EAC certificate or EAC declaration does not replace the conformity assessment procedure required under EU law. Existing technical documentation and test reports may nevertheless be helpful. Their usability depends on whether the product identity, test methods, requirements and legal prerequisites are compatible with the European procedure.

For companies serving both the European market and the EAEU, a shared technical data foundation with separate assessments for the respective jurisdictions is recommended. This allows product changes and model variants to be documented consistently.

Costs and duration of CE certification

A credible quotation should be based on the actual testing and documentation needs. Key cost factors are:

• Product type and technical complexity
• Number of variants
• Quality of existing documentation
• Required laboratory testing
• Involvement of a notified body
• Necessary design changes
• Translations and documentation

Affixing the CE marking itself is not subject to a fee. Costs arise from assessment, testing and other required services.

The processing time also depends on the project. Missing documentation, deviations identified during testing and necessary product changes can significantly affect the schedule. An early review of requirements provides a more reliable basis for market entry planning.

Common mistakes when entering the European market

Problems are particularly often caused by:

• Incomplete identification of applicable legislation
• Test reports for a different product variant
• Missing or inadequate risk assessment
• Use of unsuitable editions of standards
• Inconsistencies between the nameplate, instructions and declaration
• Missing language versions
• Unassessed changes to components or software
• Confusion between voluntary certificates and mandatory evidence

The European Commission expressly warns against unregulated “voluntary certificates” that give the impression of legally valid CE approval. Such documents do not replace any mandatory procedure or any required certificate from a competent notified body.
