Manufacturers should draw up an EU declaration of conformity to provide information required under this Regulation on the conformity of products with digital elements with the essential cybersecurity requirements set out in this Regulation and, where applicable, of the other relevant Union harmonisation legislation by which the product with digital elements is covered. Manufacturers may also be required to draw up an EU declaration of conformity by other Union legal acts. To ensure effective access to information for market surveillance purposes, a single EU declaration of conformity should be drawn up in respect of compliance with all relevant Union legal acts. In order to reduce the administrative burden on economic operators, it should be possible for that single EU declaration of conformity to be a dossier made up of relevant individual declarations of conformity.
