EU declaration of conformity multiple directives

An EU declaration of conformity multiple directives can cover one product where several CE harmonisation acts genuinely apply. The manufacturer may issue one declaration, provided it identifies every applicable directive or regulation and the technical file contains supporting evidence: risk assessment, testing, applied standards and manufacturing records.

Key takeaways

One EU Declaration of Conformity may cover several CE directives or regulations that apply to the same product model.

Every legal act listed must genuinely apply and be supported by retained evidence in the technical documentation.

The manufacturer remains responsible for conformity assessment, even where it appoints an EU authorised representative.

Radio equipment normally falls under RED; do not automatically add the EMC and Low Voltage Directives without checking their scope.

The declaration must be signed by the manufacturer or a person authorised to bind the manufacturer.

Can an EU declaration of conformity multiple directives cover several CE rules?

Yes. One EU Declaration of Conformity can bring together several directives and regulations that apply to the same product, provided the product identification and the legal acts are precise enough. This avoids creating several inconsistent documents for one commercial reference.

The EU approach is straightforward: CE marking is not a general product certificate. It means that the manufacturer declares that the product meets every applicable Union harmonisation act. Decision No 768/2008/EC, which provides a common framework for marketing products, reflects this principle for the EU Declaration of Conformity.

A single declaration is therefore often suitable for electrical or electronic equipment. For example, a non-radio mains charger may fall within the Low Voltage Directive and the Electromagnetic Compatibility Directive. One declaration can list both acts with their full references, if the testing and conformity assessment actually cover the applicable requirements.

However, one document does not allow you to ‘cover’ legislation that has not been assessed. Adding a directive as a precaution is a common mistake. It creates a conformity claim that you must be able to substantiate during an inspection or a market-surveillance request. The European Commission’s Blue Guide on the implementation of EU product rules (2022) explains that the manufacturer must identify applicable harmonisation legislation before placing a product on the market.

To frame that work from the outset, an EU Market Entry Compliance Assessment helps you identify CE, GPSR, VAT, customs, packaging, WEEE and battery issues to check for your product and trade flows.

How do you identify every applicable directive and regulation?

Start with the product’s functions, energy source and risks, not its sales title. Applicable directives and regulations depend on what the product is, its intended use and its technical characteristics.

A Bluetooth headset, for example, is radio equipment. Directive 2014/53/EU on radio equipment (RED) is the central act to assess. Within its scope, it addresses requirements including health and safety, electromagnetic compatibility and efficient use of radio spectrum. You should not assume that the EMC and Low Voltage Directives must also be declared separately: check the scope of each act.

By contrast, a wired electrical appliance with no radio function may fall under Directive 2014/35/EU on low voltage electrical equipment (LVD) and Directive 2014/30/EU on electromagnetic compatibility (EMC). The first addresses electrical risks within its voltage range. The second concerns equipment’s ability to operate without unacceptable electromagnetic disturbance and without being unduly affected by it.

Map the actual product, not just the supplier listing

Ask for and check, at minimum:

the exact model reference, variants and accessories;
the power source, voltage range and charger type;
radio modules, wireless protocols and frequencies used;
any battery, display, laser, motor or heating element;
intended use, intended users and expected operating environments;
existing documents and test reports.

Imagine a US manufacturer shipping a USB-powered connected camera to an Amazon FBA warehouse in Germany. The camera is not simply an ‘electronic accessory’: its radio functions, power supply, possible battery and domestic use all need assessment. End-of-life obligations for electrical and electronic equipment may also apply separately from CE requirements; Directive 2012/19/EU on waste electrical and electronic equipment (WEEE) is distinct from the EU Declaration of Conformity.

Our guide to RED, LVD and EMC for electronics sellers explains the practical differences between these frameworks. If you sell in several countries or store goods in a country other than the destination market, Country Compliance helps you organise checks by country of origin, storage and sale.

Do not confuse CE requirements with parallel obligations

CE marking and the EU Declaration do not replace labelling duties, possible national WEEE or battery registrations, or packaging obligations. Nor do they replace general product-safety requirements where those apply. For consumer products, Regulation (EU) 2023/988 on general product safety (GPSR) sets out, among other matters, traceability and economic-operator information obligations.

When should you use one declaration and when should you separate documents?

Use one declaration where the applicable acts concern the same identified product, the same manufacturer and the same assessed configuration. Use separate declarations where the models, variants or responsible entities are not genuinely the same.

One declaration is usually the clearest approach for a finished product. It must still identify the covered model without ambiguity. If a variant changes the Wi-Fi module, supply rating, radio software, battery or another characteristic that can affect conformity, it may need a fresh assessment and an updated declaration.

When one document is coherent

One document is appropriate where a manufacturer markets equipment identified by a model reference and the applicable directives have been assessed for that configuration. Example: an electrical adapter model ‘AX-24’, sold with the same housing, power supply and components in every Member State.

You can list all applicable directives in one section, then attach or refer to the harmonised standards and technical specifications used. The official Your Europe guidance on CE marking confirms that the manufacturer must prepare technical documentation, carry out the conformity assessment and sign the EU Declaration before affixing CE marking where it is required.

When declarations need to be distinguished

Use separate documents, or clearly differentiated declarations, where:

models have components or functions that change the applicable legislation;
different manufacturers place products on the market under their own names;
one brand reference actually covers different designs;
test evidence concerns another model with no technical justification for extending it;
a finished product and an accessory are placed on the market as separate products.

A common mistake is to reuse a supplier’s generic CE declaration across a whole range. A document that does not name the correct model, manufacturer or legal acts does not support your market placement. Before placing an order, Supplier Check can help you centralise supplier identity, payment and delivery information so that inconsistencies can be reviewed.

What must the declaration include for each applicable directive or regulation?

The declaration must identify the product, the manufacturer and the Union acts for which conformity is declared. It should allow an authority to connect the document to the physical product, its technical file and the person binding the manufacturer.

The annex templates in the sectoral directives set out the expected elements. In one combined document, you can group common information and then list all applicable acts. See our guide to EU Declaration of Conformity content, signature and supporting documents to structure the document without confusing a declaration with a test report.

Information to include in the declaration

The exact format depends on the applicable act, but an EU Declaration of Conformity commonly includes:

a declaration number or reference for traceability;
product identification: type, model, batch or serial number where relevant;
the manufacturer’s name and address or, where applicable, its authorised representative’s details;
a statement that the declaration is issued under the sole responsibility of the manufacturer;
the subject of the declaration, with a sufficiently clear product description;
the list of applicable Union directives and regulations;
references to harmonised standards or other technical specifications used, where stated;
notified body details and certificate information, only where notified-body involvement is required;
place and date of issue, plus the name, role and signature of the authorised signatory.

Harmonised standards can provide a presumption of conformity for the requirements they cover, but they are not an automatic formula. You must check their relevance, version and scope for the product concerned. If a notified body is involved, verify its competence and the scope of its work in NANDO before relying on a certificate.

How do you structure the declaration for electrical or radio equipment?

For radio equipment, begin with RED and build the declaration around the model that was actually assessed. Add other acts only after checking their scope, exclusions and the product’s characteristics.

Hypothetical example: rechargeable Bluetooth speaker

Assume a rechargeable Bluetooth speaker sold as ‘SoundBox S1’, with an integrated radio module and rechargeable battery. The manufacturer must first establish the applicable requirements for radio equipment under RED. It must then assess battery, WEEE, labelling and national compliance-scheme obligations separately; these do not automatically become statements in a RED declaration.

One declaration could follow this structure:

Product: rechargeable Bluetooth speaker, model SoundBox S1, with enough technical description to distinguish it from a variant.
Manufacturer: full legal name and address of the entity placing the product on the market under its name or trade mark.
Responsibility: declaration issued under the manufacturer’s sole responsibility.
Legislation: Directive 2014/53/EU on radio equipment, if the assessment confirms that it applies.
Standards and evidence: references to applied standards or specifications that match the test reports and risk assessment.
Signature: date, place, name, role and signature of the authorised person.

If the speaker is sold online, the full declaration is not necessarily the only information to make available on the listing. Safety, traceability and economic-operator information must also be checked against GPSR and distance-selling rules. Before publication, the Marketplace Product Compliance Scanner can flag compliance information to verify in an Amazon, eBay, Etsy, Shopify or other marketplace listing.

EU Seller Kit — Use the Marketplace Product Compliance Scanner before publishing a listing to check the traceability, safety and compliance information that still needs attention.

Which documents must support the EU Declaration of Conformity?

The EU Declaration is a concise legal statement; it does not replace the technical file. Each directive or regulation listed must be linked to retained evidence that can be made available if a competent authority asks for it.

The technical file brings together the material explaining why the product conforms: product description, design and manufacturing information, risk assessment, applied standards, calculations, test reports, instructions, labelling, control procedures and a copy of the signed declaration. The Commission’s Blue Guide states that technical documentation should enable an assessment of the product’s conformity with applicable requirements.

Link every claim to identifiable evidence

To avoid an unusable file, create a simple internal matrix: one row for each applicable requirement, one column for evidence, another for the document version and a final column for the person responsible for updates. This is particularly useful when a product changes or several laboratories have performed testing.

A stand-alone test report is not always enough. Check that it concerns the correct model, in the correct configuration, using a relevant method and with usable results. A report for a different charger, an old software version or a replaced radio module may no longer support the declaration.

Use the practical list in our guide to CE technical documentation: documents and evidence to prepare. If you import from Shenzhen to a German FBA warehouse, request these materials before dispatch. A customs hold, blocked listing or market-surveillance request is much harder to manage after the stock has arrived.

Who signs the declaration and what does a CE authorised representative do?

The manufacturer signs the EU Declaration of Conformity, or a person authorised to sign on its behalf and under its responsibility does so. A CE authorised representative may carry out specific tasks under a written mandate where applicable legislation permits it, but it does not take over the manufacturer’s fundamental duty to design, assess and document the product.

The manufacturer is the entity that makes a product, or has it designed or made, and markets it under its own name or trade mark. An importer that applies its own brand or modifies a product in a way that may affect conformity can take on manufacturer obligations; assess this case by case.

What an authorised representative can and cannot do for a non-EU manufacturer

A manufacturer established outside the EU may need to appoint an authorised representative for certain CE products, depending on the applicable act and the market-placement arrangement. The mandate must be written, specific and accepted. It may provide, for example, for documents to be held or made available to authorities, within the limits of the relevant legislation.

This does not mean that a software subscription automatically appoints a representative. The CE Authorised Representative service becomes active only after acceptance, entity assignment, a signed mandate and active payment. It does not replace the manufacturer’s conformity assessment, testing, technical documentation or EU Declaration of Conformity.

Also distinguish a CE authorised representative from a GPSR responsible person. The roles can overlap in some product and business arrangements, but they are not interchangeable. Our guide to the role and limits of a CE authorised representative explains the difference before you choose an arrangement.

EU Seller Kit — The CE Authorised Representative service is for a non-EU manufacturer that needs a written authorised-representative mandate where applicable CE legislation allows it; it does not substitute for your conformity evidence.

What checklist should you complete before placing a product on the EU market?

Before placing the product on the market, check that the declaration matches the actual product and that the technical file can support it. This final review helps prevent reference, version and signature errors that often trigger follow-up requests.

Pre-market checklist

Do not treat this list as automatic approval. Requirements depend on the product, its configuration and the countries where you store or sell it. For a broader view of the process and responsibilities, read the practical CE marking guide for EU manufacturers and sellers. If you are unsure about a directive’s scope, a standard or the assessment procedure, consult the competent authority, a qualified laboratory or a specialist adviser.

Frequently asked questions

Can you cite RED, EMC and the Low Voltage Directive in the same declaration?

Yes, if all three acts genuinely apply to the product and your technical file contains evidence for each claim. However, RED already covers certain safety and electromagnetic-compatibility aspects for radio equipment within its scope. Check each directive’s exclusions and precise scope before combining them.

Is a Chinese supplier’s CE Declaration of Conformity enough?

Not necessarily. Check the manufacturer’s identity, exact model reference, cited legislation, signature and the existence of associated technical evidence. A generic, unsigned declaration or one that identifies another model does not demonstrate conformity of the product you import.

Must an EU Declaration of Conformity accompany every product?

How it must be supplied depends on the applicable legislation and product. The declaration must in any event be available to competent authorities under the relevant rules, and some directives require it to accompany the product or be supplied with it. Check the annex to the relevant directive before choosing a paper or digital format.

Does the EU Declaration of Conformity need to be translated?

The required language depends on the applicable legislation and on requests from authorities in the Member State where the product is made available. Prepare a version that can be understood in the intended markets and maintain document control over translations. Instructions and safety information also have country-specific language requirements.

Can a CE authorised representative sign instead of the manufacturer?

An authorised representative may receive specific tasks under a written mandate, within the limits of applicable legislation. That does not transfer responsibility for the product’s design and manufacturing conformity, which remains with the manufacturer. Whether it may sign in practice must be checked against the mandate and the relevant sectoral act.

Does a product modification require a new declaration?

A modification that may affect conformity should trigger reassessment, an update to the technical file and, where necessary, a new or revised declaration. This can apply where a radio module, power supply, battery, compliance-relevant software or safety component changes. Document the assessment rather than relying on the product’s outward similarity.
