(23)In order to safeguard the functioning of the internal market and to ensure that the objective of providing a high degree of protection of human health and the environment is achieved, it is necessary to establish that detergents and surfactants from third countries entering the Union market, including via online sales, also comply with this Regulation. In particular, it is necessary to ensure that appropriate conformity assessment procedures have been carried out by manufacturers with regard to those products. It is also necessary to lay down rules for importers to ensure that the detergents and surfactants placed on the market comply with those requirements. Importers and authorised representatives should ensure that the documentation drawn up by manufacturers is available for inspection by the competent national authorities. Provision should be made for importers and, where applicable, authorised representatives to ensure that a digital product passport has been created for detergents and end-user surfactants.
