# EU Declaration of Conformity

> The formal document in which the manufacturer states, on its sole responsibility, that a product meets the requirements of the applicable Union legislation.

## Definition

The EU declaration of conformity is the document by which the manufacturer states, on its sole
responsibility, that the applicable requirements of Union harmonisation legislation have been
fulfilled for an identified product.

## Expanded Explanation

The declaration identifies the product, lists the Union legislation it satisfies, references the
standards or specifications applied, names any notified body involved, and is signed on behalf of
the manufacturer. Under Regulation (EU) 2024/1781 its content follows Annex V, and drawing it up
means the manufacturer assumes responsibility for the product's compliance with the ecodesign
requirements that apply.

Where several Union acts apply to the same product, a single declaration covering all of them is
normally drawn up so that authorities receive one document rather than several.

The declaration is a statement, not evidence. Its credibility rests entirely on the technical
documentation and the conformity assessment behind it.

## Why It Matters

Signing the declaration is the moment legal responsibility crystallises around a named legal person.
That is why the roles that may sign it, and the internal approvals that must precede it, belong in
the governance model rather than in a document template.

## Legal and Regulatory Context

Regulation (EU) 2024/1781, Article 44 and Annex V, alongside Decision No 768/2008/EC, which
establishes the common framework for conformity assessment modules and declarations in EU product
law.

## Relationship to Adjacent Concepts

The declaration follows the conformity assessment and rests on the technical documentation. Where a
product-specific measure requires it, selected declaration content may also surface in the Digital
Product Passport.

## Common Misconceptions

#### A declaration of conformity is issued by an authority

It is issued by the manufacturer. A certificate from a notified body is a different document with
a different author and a narrower scope.
