# Notified Body

> A conformity assessment body designated by a Member State and notified to the Commission to carry out third-party assessment tasks under specific Union legislation.

## Definition

A notified body is a conformity assessment body that a Member State has designated and notified to
the European Commission as competent to carry out third-party conformity assessment tasks under a
specific piece of Union harmonisation legislation.

## Expanded Explanation

Notified bodies are private or public organisations assessed against competence, impartiality and
capability criteria, then designated for a defined scope. They are listed in the Commission's NANDO
database with the legislation and product ranges they cover, and each carries a four-digit
identification number.

Whether a notified body is involved at all depends on the conformity assessment module that the
applicable legislation prescribes. Many modules are internal production control, where the
manufacturer assesses conformity itself; others require type examination or quality system approval
by a third party. Under the current ESPR framework, the assessment route for a given product group
is set by the applicable delegated act rather than by the framework regulation.

## Why It Matters

Involving a notified body changes lead times, cost and the documentary trail. Assuming third-party
assessment where none is required wastes budget; assuming self-assessment where a module requires a
notified body invalidates the declaration.

## Legal and Regulatory Context

Regulation (EU) 2024/1781, Chapter X on notification of conformity assessment bodies, and Decision
No 768/2008/EC for the underlying module framework.

## Relationship to Adjacent Concepts

A notified body performs conformity assessment before placing on the market. A market surveillance
authority acts afterwards. Neither issues the EU declaration of conformity.

## Common Misconceptions

#### Every CE marked product has been checked by a notified body

Most have not. Where a notified body is involved its identification number appears alongside the
CE marking; where the module is internal production control, no number appears.
