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

No. CE compliance is tied to the specific configuration that was tested and documented. Any change that can affect electromagnetic emissions, immunity, safety, or radio performance can invalidate the original test basis. Hardware revisions, enclosure changes, power supply substitutions, firmware changes that alter clocking or duty cycle, and antenna changes for radio products can all materially change EMC behavior. When changes occur, the manufacturer must assess whether the

You should maintain a defensible technical compliance file for the finished product, not just the module grant. This should include the FCC and ISED certificates for the radio module; the integration guidance from the module grantee; RF exposure assessments for the final product configuration; host-level emissions verification results, where applicable; antenna specifications and placement documentation; and user manual and labeling compliance statements. Regulators and custo

No. Modular approval simplifies transmitter certification, but it does not certify the finished product. The host device must still comply with unintentional radiator requirements, RF exposure rules, labeling and user manual requirements, and any applicable co-location or simultaneous transmission constraints. The moment you integrate the module into a real enclosure with power supplies, processors, displays, cables, and other radios, you have created a new RF system. FCC and

Only if the change does not alter compliance assumptions. Antenna type, gain, placement, grounding, and matching directly affect radiated emissions and RF exposure. Even when a grant does not specify antennas, the final product must still comply with RF exposure and emissions limits. Moving an antenna closer to users, switching to a higher-gain antenna, or changing the ground reference can push the product out of compliance. In both FCC and ISED regimes, antenna changes are o

Yes, potentially. Certification is tied to how the transmitter operates, not just the physical hardware. Adding new frequency bands, enabling higher duty cycles, changing modulation behavior, increasing output power, or activating new operating modes can materially change the compliance basis. Even changes that appear software-only can trigger regulatory impact if they affect emissions, spectrum use, or RF exposure. FCC and ISED both expect manufacturers to evaluate whether c
