CE Marking and Conformity Certification in the European Union

CE marking serves as confirmation that a product complies with the applicable requirements of EU legislation on safety, health protection, electromagnetic compatibility, and other mandatory aspects – depending on the product category.

In practice, the mistake most often occurs at the very beginning: the product is assigned to the wrong category, a “similar” standard is chosen instead of the correct one, or testing is planned that does not cover the requirements of the specific directive/regulation. We structure the project so that you have a clear logic: what exactly applies, what evidence is needed, and how to assemble a documentation package that stands up to inspection (including market surveillance).

Which products are subject to CE marking

CE marking is required only for products that fall under specific EU directives and regulations. The key principle is this: first we determine the product’s intended purpose and risks, then which EU legal acts apply to it and what evidence is needed.

In practice, several requirements often apply at the same time. For example, a machine or production line may fall under safety requirements (for machinery) and, at the same time, under electromagnetic compatibility (EMC) and/or low-voltage requirements (LVD). Certain categories are additionally affected by restrictions on hazardous substances (RoHS), operation in explosive atmospheres (ATEX), or requirements for pressure equipment (PED).

When a Notified Body is required

A Notified Body is not always required. Its involvement depends on the specific directive/regulation, the level of risk, and the selected conformity assessment module. It is important not to make a mistake at this stage: an “extra” Notified Body increases the timeline and cost of the project, while the absence of one where it is mandatory makes the entire documentation package invalid.

A Notified Body is usually involved where EU rules require an independent third-party assessment and/or a production audit. This is the case, for example, for higher-risk products, when type examination is required, when modules involving assessment of the quality system are used, and when surveillance during the validity of the document is provided for. These cases also include certain categories of products for which the requirements expressly provide for the involvement of a Notified Body.

Technical documentation and the EU Declaration of Conformity (EU DoC)

The key to robust CE is not one “main” document, but an interconnected evidence base: the product identification, risk assessment, applied standards, and test reports must match in terms of version/configuration and the logic of the requirements. If a report formally exists, but the configuration does not correspond to the supply, and modifications are mixed within one package, the documents become vulnerable during review—for both the customer and market surveillance.

After marking: obligations and market surveillance

After the product has been placed on the market, it is important to be able to quickly confirm conformity for the specific product version and the specific supply. In practice, this means that the technical documentation must be available and up to date, changes must be assessed for their impact on the requirements, and complaints and incidents must be addressed through corrective actions.

We establish clear rules in advance: who keeps the documentation package, how modifications are recorded, how complaints are handled, and how changes are documented, so that when a request comes from a customer or surveillance authority, you do not have to “reassemble the technical file from scratch” under stress.

Why projects trust us with conformity

We manage the EU conformity project so that you have a clear route and an expected result. In complex cases, we take on coordination between participants and involve specialized experts when it is truly required.
