(111)Manufacturers should draw up an EU declaration of conformity to provide information on the conformity of packaging with this Regulation. It is possible that manufacturers are also required to draw up an EU declaration of conformity under other Union law. To ensure access to information for market surveillance purposes, a single EU declaration of conformity should be drawn up in respect of all relevant Union legal acts. To reduce the administrative burden on economic operators, it should be possible for that single EU declaration of conformity to comprise a dossier of relevant individual declarations of conformity.
