The manufacturer placing the product on the EU market is legally responsible, even if testing and certification work is outsourced. This responsibility cannot be shifted to a test lab, a module vendor, or a contract manufacturer. The party named on the Declaration of Conformity is the one that EU authorities will hold accountable if the product is found noncompliant. That includes responsibility for maintaining the technical documentation, ensuring ongoing conformity as the p

Yes. Pre-certified radio modules can simplify the radio conformity assessment under the Radio Equipment Directive, but they do not eliminate the need to evaluate the finished product. The final product must still be assessed for EMC, safety, and proper radio spectrum use in its integrated form. The enclosure, antenna configuration, grounding, power architecture, and co-located electronics can materially change compliance outcomes. Module certifications are inputs to your tech

They must be made available to EU market surveillance authorities upon request, and there must be a responsible economic operator in the EU who can provide them. While the technical file need not be stored on a specific server within the EU, it must be readily accessible and provided without delay if requested by the authorities. This includes EMC test reports, safety reports, risk assessments, and the Declaration of Conformity. If you cannot produce this documentation prompt

A valid EU Declaration of Conformity must identify the product, the manufacturer or authorized representative, and the applicable EU directives and harmonized standards to which conformity is declared. This typically includes the EMC Directive, the Low-Voltage Directive (where applicable), and the Radio Equipment Directive for wireless products. The declaration must reference the specific standards used to demonstrate compliance and must be signed by a person empowered to bin

No. A power supply’s CE report only covers the power supply as a standalone component under its own test configuration. It does not automatically confer CE compliance on the finished product. In the final product, the power supply interacts with various loads, grounding, cable configurations, enclosures, and operating modes, which can materially affect conducted and radiated emissions and immunity behavior. You can reference the power supply’s safety documentation as part of
