If a product is covered by several CE directives do I need multiple Declarations of Conformity or just one?

A single EU CE Declaration of Conformity can cover multiple EU directives and regulations as long as it clearly identifies the product and lists every applicable legal act, harmonized standards, and the responsible manufacturer details. You do not need separate Declarations just because more than one directive applies.

In practice, most manufacturers issue one consolidated Declaration to meet CE marking requirements and to keep their technical documentation consistent across the full EU conformity assessment. Separate Declarations are only used in specific situations where product scope, variants, or compliance responsibility must be separated.

The questions below explain when one Declaration is enough, what it must contain, and when separate documents can make sense.

When can one EU Declaration of Conformity cover multiple directives or regulations?

One EU CE Declaration of Conformity can cover multiple EU directives or regulations when the same product is placed on the market as a single item and all applicable CE legislation can be listed together with the relevant standards and conformity assessment details. The Declaration must unambiguously link the product to all the legal requirements it meets.

This is the common approach for products that fall under more than one CE legal act, for example electrical equipment that also has radio functionality, or machinery that includes electrical components. A consolidated Declaration works well when:

  • The product identity is clear and stable, such as model name, type, SKU, or batch reference
  • All applicable CE legal acts are known and can be listed accurately
  • The same manufacturer takes responsibility for compliance across the full product configuration
  • The supporting technical documentation covers each applicable requirement and standard

From an enforcement perspective, one complete Declaration makes it easier for authorities and marketplaces to verify that the product has been assessed against the full set of applicable rules, not just one directive.

What must be included in the Declaration of Conformity when several directives apply?

When several CE directives or regulations apply, the CE Declaration of Conformity must identify the product, name and address the manufacturer, list all applicable EU legal acts, and reference the harmonized standards or other specifications used to demonstrate compliance. It must also include the signatory details and the date and place of issue.

To keep the Declaration robust for EU conformity assessment and market checks, include the following elements in a clear, scannable format:

  • Product identification: product name, model or type, and any traceability identifiers
  • Manufacturer identification: legal entity name and full postal address
  • Statement of conformity: a clear declaration that the product conforms to the listed legislation
  • Complete list of applicable EU acts: each directive or regulation that applies to the product
  • Standards and specifications: harmonized standards, test methods, or other technical specifications used
  • Notified Body details: only when a Notified Body is involved, include name, number, and certificate references as required by the applicable act
  • Signature block: name and function of the authorized signatory, signature, place, and date

A frequent compliance failure is listing only one directive while the product clearly triggers others. That mismatch can lead to marketplace blocks or authority questions because the Declaration no longer reflects the actual product configuration.

Do you ever need separate Declarations of Conformity for the same product?

Separate Declarations of Conformity are not usually required for the same product, but they can be appropriate when different product variants, brand owners, or manufacturing entities need distinct legal responsibility, or when a product is placed on the market in configurations that change which EU acts apply. The goal is clarity, not duplication.

Common situations where separate Declarations can be justified include:

  • Different variants with different compliance scope: one model includes radio and another does not, so the applicable legislation differs
  • Multiple legal manufacturers: the brand on the label changes and each legal entity must issue its own Declaration
  • Private label arrangements: the entity placing the product on the market under its name may need its own Declaration aligned to its role
  • Major design changes: a redesign affects essential requirements, standards, or test evidence, making a new Declaration the cleaner option
  • Portfolio management: separating Declarations can reduce confusion when one document would become overly broad and hard to maintain

Even when separate Declarations exist, they must stay consistent with the underlying technical documentation. If the file shows one configuration but the Declaration describes another, that inconsistency is what typically creates regulatory friction.

Also note that CE documentation sits alongside other EU product safety obligations. For non CE consumer products, the General Product Safety Regulation (EU) 2023/988 (GPSR) can still apply, and for certain supply chain roles the Market Surveillance Regulation (EU) 2019/1020 (MSR) sets obligations such as ensuring an EU-based economic operator is identified for relevant products.

How EARP helps with CE Declarations of Conformity for multi-directive products

For multi-directive products, the fastest path to a defensible CE Declaration of Conformity is a structured check that aligns multiple EU directives, the chosen EU conformity assessment route, and the supporting technical documentation. We help you reduce uncertainty by verifying what applies, what evidence is needed, and how to present it clearly for authorities and marketplaces.

  • Map the product to applicable CE legislation and confirm the correct scope for each directive or regulation
  • Review your Declaration content for completeness, including standards, product identifiers, and signatory details
  • Check documentation readiness so the technical file supports every listed requirement
  • Support GPSR and MSR alignment where relevant, including EU-based economic operator role clarity
