Members Question: Can declarations cover more than one product?

The CE Marking Association offers membership to companies who want support on CE Marking on a regular basis. Members are invited to ask questions and when there is a question that might be of interest to a wider audience, we like to publish them in our news section. Some of the details may have been altered for confidentiality reasons.

Your Question

We are looking to use a ‘tracking device’ which has been externally sourced. We obtained a CE declaration for the pre-production unit, but changes have been made to the original CE certified model, such have incorporating battery management components and it now features a tamper alert system. We believe that this is a significant modification and therefore where expected to be provided with a new CE declaration. The suppliers say it is covered by the original CE declaration. Is this correct?


It is possible to cover many variants on the same Declaration of Conformity. You may wish to check that this variant is listed separately on the DofC to the original. Else a new Declaration is required specifically for this variant.
