CE Technical Documentation: Documents and Evidence to Prepare Before Placing a Product on the Market is the evidence a manufacturer uses to show that a CE-marked product meets the applicable EU requirements. Prepare it before signing the EU Declaration of Conformity and placing the product on the market, then keep it available for the period required by the relevant legislation.
Key takeaways
- The manufacturer is responsible for CE technical documentation, including where production is outsourced outside the European Union.
- CE marking is neither a generic certificate nor stand-alone proof; it must be supported by a documented conformity-assessment procedure.
- Test reports, risk assessments, drawings, applied standards and the EU Declaration of Conformity must match the product actually sold.
- An importer, distributor, marketplace or market-surveillance authority may request compliance documents, and inconsistent evidence can lead to a blocked listing or corrective action.
- A CE authorised representative may receive specified tasks under a written mandate, but does not replace the manufacturer’s conformity assessment, testing, technical documentation or EU Declaration of Conformity.
Who must prepare CE Technical Documentation: Documents and Evidence to Prepare Before Placing a Product on the Market?
The manufacturer has primary responsibility for the CE technical file. That responsibility remains with you when you sell under your own brand a product made by a supplier, even where the supplier has already supplied test reports or a declaration of conformity.
Under EU product rules, a manufacturer is generally the person who makes a product, or has it designed or made, and markets it under their own name or trade mark. Decision No 768/2008/EC sets out the common framework for marketing products, while the European Commission’s [Blue Guide (2022)](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:52022XC0629(04) explains the roles of economic operators and the practical logic of conformity.
Manufacturers established in the EU
If you design and sell an electrical device under your own brand from France, you must identify the applicable legislation, carry out the conformity assessment, compile the documentation and sign the EU Declaration of Conformity. You may appoint a laboratory to test the product or a consultant to help draft documents, but you do not transfer your manufacturer responsibility.
Non-EU sellers, importers and brand owners
If you ship from Shenzhen to an Amazon FBA warehouse in Germany under your own brand, you will often be treated as the manufacturer even though a Chinese factory physically makes the item. You therefore need to obtain the source documents, check that they relate to your exact model and organise the evidence before importation. If you are planning a first shipment, an EU market-entry compliance assessment helps you identify the CE, GPSR, customs and VAT checks to review for your products and trade flows.
An EU-established importer must also verify that the manufacturer has followed the appropriate conformity-assessment procedure and that the required documentation is available. Receiving a PDF labelled “CE certificate” is not enough.
Distributors and marketplaces
A distributor must act with due care when making a product available. Where applicable, it must check that required markings and information are present. Marketplaces may also request an EU Declaration of Conformity, test reports or labelling photographs before publication or after a complaint.
Before publishing a listing on Amazon, eBay, Etsy or Shopify, use the Marketplace Product Compliance Scanner to flag traceability, safety and compliance information to check in the listing. It does not legally approve the product, but it can help prevent your listing from contradicting your technical documentation.
EU Seller Kit — For a CE-marked product made outside the EU, the most relevant options are the EU market-entry compliance assessment, the Marketplace Product Compliance Scanner and, where the applicable legislation permits it, the CE authorised representative service.
Which products need CE technical documentation?
CE technical documentation is required where a product falls within EU harmonisation legislation that requires CE marking. CE marking does not apply to every product sold in Europe, so you must never add it as a precaution to a product not covered by legislation requiring it.
The official Your Europe guidance on CE marking confirms that CE marking is reserved for product categories covered by specific EU rules. Your first task is therefore to classify the product accurately, including its functions and intended use.
Common product categories
Toys fall under Directive 2009/48/EC on the safety of toys. A toy requires a safety assessment and documentation suited to its characteristics, intended age group and foreseeable hazards.
Radio equipment, such as a Bluetooth smartwatch or GPS tracker, may fall under Directive 2014/53/EU on radio equipment. Depending on the product, other requirements may also apply, including electromagnetic compatibility or electrical safety requirements.
An electrical appliance may fall within both the Low Voltage Directive 2014/35/EU and Directive 2014/30/EU on electromagnetic compatibility. Review all applicable legislation, not only the rule that appears most obvious.
CE marking and GPSR are not the same framework
Regulation (EU) 2023/988, the General Product Safety Regulation (GPSR), applies to many consumer products and may complement sector-specific requirements. GPSR does not automatically make a product a CE-marked product. Equally, CE marking does not necessarily meet every GPSR requirement on safety, traceability or consumer information. Read Regulation (EU) 2023/988 alongside this practical guide to GPSR risk assessment to separate the two exercises.
Example: a connected decorative lamp may need CE assessment for its electrical and radio functions. If it is sold to consumers, you must also consider GPSR traceability details, warnings and responsible-operator information.
What documents must a CE technical file contain?
The exact content depends on the applicable legislation, the product’s risk profile and its technical characteristics. In practice, a sound file lets you trace the link between the product sold, the requirements that apply, the engineering choices made, the tests performed and the final declaration.
The European Commission’s [Blue Guide (2022)](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:52022XC0629(04) states that technical documentation must provide the information needed to assess conformity. A supplier statement with no technical description or usable evidence will rarely be sufficient.
The core documents to collect
Keep a clear product description: trade name, model or SKU, variants, photographs, intended use, intended users and limits on use. Include relevant drawings, diagrams, bills of materials, software or firmware versions, and the list of critical components where they affect conformity.
The file should also include a risk assessment. This identifies reasonably foreseeable hazards, evaluates the risks and explains the chosen controls: product design, physical safeguards, warnings, instructions or restrictions on use. For a charger, for example, the assessment should connect electrical and thermal risks to the technical measures and relevant tests.
The following evidence is commonly needed:
- applicable EU legislation and the essential requirements assessed;
- harmonised standards or other technical specifications used, including their version and scope;
- test reports, calculations, assessments and certificates where these are required;
- relevant design and manufacturing drawings or diagrams;
- instructions, warnings, labels and safety information supplied to the user;
- production-control procedures where conformity depends on consistent manufacture;
- the signed EU Declaration of Conformity.
The EU Declaration of Conformity: content, signature and documents to prepare is a separate document. It records the manufacturer’s formal commitment, but it never replaces the technical evidence supporting that commitment.
Evidence must match the model you sell
A common mistake is accepting a test report for a similar reference, a different photographed product or an earlier component. A different battery, power supply, antenna, plastic material, charger or software version can change whether the evidence remains relevant.
Ask the supplier for the exact tested model reference, report annexes, laboratory identity, date, standards used and product photographs. Before placing an order, Supplier Check helps you centralise supplier identity, payment and delivery details so that you can identify inconsistencies for review. It does not replace a technical review of test evidence.
How do you prepare CE technical documentation step by step?
The most reliable method starts with the real product and works back to the legal requirements, rather than starting with a declaration template to sign. Begin before mass production: correcting a design issue after stock has arrived usually takes more effort than checking it early.
1. Define the product and its intended use precisely
Fix the model reference, variants, accessories, materials, power supply, digital functions and intended users. The same housing may be subject to different rules if it includes radio functionality, a battery, a laser or is intended for children.
Example: a US manufacturer sells a rechargeable night light. A USB-only version and a Bluetooth version should not be treated as one product without further analysis, because the radio function can create additional requirements.
2. Identify applicable legislation and standards
Create a simple matrix. For each requirement, record the applicable legislation, the standard or method selected, evidence available and the person responsible for the action. The practical guide to CE marking requirements can help you structure this stage.
For imported goods, correct customs classification does not determine CE legislation on its own, but it helps you describe the goods accurately and prepare the import. The HS classification assistant generates candidate HS subheadings for you to confirm in the Combined Nomenclature or TARIC. Always verify the result using the European Commission’s TARIC consultation database.
3. Carry out the risk assessment and select evidence
For every identified hazard, define the control measure and the evidence expected. Evidence may be a test report, calculation, inspection, design validation or component documentation. Harmonised standards can make it easier to demonstrate conformity where they cover the relevant requirements, but they must be appropriate to the product.
Do not select a standard simply because it appears in a supplier report. Check its subject matter, version, test conditions and any limitations in the report.
4. Arrange testing and review the results
Where testing is needed, send the laboratory a sample representative of the intended production. Keep complete reports, not only a summary page. If the product changes after testing, document the effect of the change and decide whether further checks are needed.
A notified body is not required in every case. Its involvement depends on the legislation, product category and applicable conformity-assessment procedure. Read our guidance on when a notified body is required for CE marking before assuming that a “CE certificate” is either necessary or sufficient.
5. Sign the declaration, apply CE marking and archive the file
Once the assessment is complete, the manufacturer draws up and signs the EU Declaration of Conformity where the applicable legislation requires it. The manufacturer then applies CE marking in accordance with the relevant rules, together with any other information required on the product, packaging or accompanying documents.
Archive the file in a version-controlled structure. Link every product reference sold to its declaration, reports, instructions, labelling photographs and change history. This discipline makes it easier to respond to a marketplace or authority request.
Checklist before placing a product on the market
- The product reference, variants and accessories are identified without ambiguity.
- Applicable EU legislation has been assessed for the product’s actual functions and intended use.
- The risk assessment links each significant hazard to a control measure and supporting evidence.
- Test reports cover a representative sample and relevant standards.
- Instructions, warnings and labels match the product and destination markets.
- The EU Declaration of Conformity identifies the correct manufacturer, product and applicable legislation.
- CE marking is applied only where legislation requires it and the procedure is complete.
- Documents are dated, archived and accessible if requested during a check.
When must you update CE documents and evidence?
A CE technical file is not a static document created once and forgotten. Review it whenever a change could affect product conformity, risk or information supplied to users.
A change to the battery supplier, circuit board, material, charger, software, factory or production method may require an impact assessment. Apply the same caution when you add a function, change intended use or begin selling a variant under a new reference.
Managing production changes
Imagine your supplier replaces a lamp’s mains adaptor with a cheaper model. The product may look identical, but electrical safety and test results may no longer be transferable. Obtain the new component specifications, compare them with the existing file and add or update evidence where needed.
Maintain a change register recording the date, affected reference, change made, impact assessment, decision and updated documents. This is not administrative box-ticking. It helps prevent you presenting an authority with a report for a version that is no longer manufactured.
Preparing for a compliance request
Market-surveillance authorities can request information and documents from economic operators. Regulation (EU) 2019/1020 on market surveillance and compliance of products provides the enforcement framework for products covered by EU harmonisation legislation.
In practice, prepare a readable version of the file with an index and consistent file names. Documentation scattered across messages, with no link between the SKU sold and its test report, slows your response and can make conformity harder to demonstrate.
How much effort is involved, and which mistakes should you avoid?
The effort depends mainly on product complexity, applicable legislation, supplier maturity and the quality of available evidence. It is not limited to the cost of a test report: allow time to classify the product, review documents, correct gaps, adapt labelling and manage versions.
To compare SaaS plans and supplementary services without inserting a price into your internal documentation, see EU Seller Kit pricing and plans. Regulatory work, testing and any external intervention remain specific to your product and organisation.
Mistakes that most weaken a technical file
The first mistake is confusing a certificate, a test report and an EU Declaration of Conformity. A report may support part of an assessment; a declaration commits the manufacturer; a certificate may matter in a specific procedure. None automatically replaces the others.
The second is copying a declaration found online. A declaration that names irrelevant directives, the wrong product reference or standards unrelated to the product can indicate inadequate review to a marketplace or authority.
The third is assuming a CE authorised representative “takes over” compliance. A CE authorised representative acts, where the applicable legislation permits, under a written mandate. The service becomes active only after acceptance, entity assignment, signature of the mandate and active payment. It does not replace the manufacturer’s responsibility, conformity assessment, testing, technical documentation or EU Declaration of Conformity.
Finally, do not confuse a CE authorised representative with a GPSR responsible person. For relevant consumer products, an EU-established responsible person may be required under GPSR. The GPSR Responsible Person service is separate and becomes active only after product review, entity assignment, a signed mandate and active payment; a SaaS subscription does not automatically appoint a representative.
Which special cases should you anticipate?
Products combining several functions, white-label imports and distance sales need particular care. Your documentation must reflect the complete product and its route to market, not merely its main component.
Products made in China under your brand
Request documents before final payment and before shipment. Check the manufacturer’s identity and the consistency of photographs, model references, reports and declarations. Our guide to CE marking for products made in China explains the checks to carry out before importation.
If you import stock into the EU, product compliance does not replace customs formalities. You may need an EORI number for customs operations; the European Commission explains the purpose of the Economic Operators Registration and Identification number. The EORI file preparation service prepares your application file; the number itself is issued by the competent customs authority.
Electronics, radio equipment and batteries
For a connected product, check its actual functions: Wi-Fi, Bluetooth, NFC, charging, mains supply, an integrated battery or a mobile app. These features can change the legislation and testing you need. See our guide to RED, Low Voltage and EMC requirements for electronics sellers.
A battery can create obligations separate from CE marking, including under Regulation (EU) 2023/1542 on batteries and waste batteries. Do not mix CE evidence with separate waste-management, registration or data obligations that may apply.
Online sales and visible information
You do not need to publish the full technical file on a product listing. However, distance selling may require identification, safety and economic-operator information to be displayed. GPSR contains specific requirements for distance-sale offers; see our guide to GPSR Article 19 information for online product listings.
The practical consequence is straightforward: your listing, packaging, instructions and technical file must tell the same story. A different reference or missing warning can trigger a request for evidence or suspension of the listing.

Frequently asked questions
Must CE technical documentation be sent to an authority before sale?
Usually, the technical documentation is not routinely filed with an authority before sale. However, the manufacturer must compile, retain and provide it when a competent authority requests it. Some product categories or procedures have specific requirements, so check the sector legislation that applies to your product.
Is a supplier’s CE certificate enough to sell a product?
No. A document called a “CE certificate” does not, by itself, demonstrate that a product is compliant. You need to check the applicable procedure, supporting reports and evidence, their match with the product sold, and the manufacturer’s EU Declaration of Conformity.
How long must CE technical documentation be kept?
The retention period depends on the legislation applying to the product. Many EU acts require long-term retention after the product is placed on the market, often ten years, but you should verify the rule for your product category before setting an archive policy.
Does the technical file need to be translated into English?
The required language depends on the applicable legislation and the authority requesting the documents. Keep documentation clear and usable, then check the language requirements in the countries where you sell the product or where it may be inspected.
Can I use my factory’s test reports?
Yes, if you verify that they are authentic, relevant and applicable to the product actually placed on the market. Check the model reference, photographs, components, standards, dates, tested sample and any conditions or exclusions in the report.
Does a packaging change mean I must redo the technical file?
Not necessarily. A purely graphic change may have limited impact, but it needs review if it affects warnings, mandatory information, product identification or instructions. Any change that could affect safety or conformity must be documented and may require new evidence.
Is CE marking enough to sell a consumer product in the EU?
No. CE marking addresses sector-specific requirements where it applies, but other obligations may also apply, including GPSR, distance-sale information, labelling, VAT, customs, packaging, WEEE or batteries. Assess the product, storage country, destination countries and your role in the supply chain.
