(170)A procedure should exist under which interested parties are informed of measures intended to be taken with regard to packaging presenting a risk. It should also allow market surveillance authorities in the Member States, in cooperation with the relevant economic operators, to act at an early stage with regard to such packaging. In order to ensure uniform conditions for the implementation of this Regulation, implementing powers should be conferred on the Commission to determine whether national measures in respect of non-compliant products are justified. The Commission should adopt immediately applicable implementing acts where, in duly justified cases relating to the protection of the environment or human health, imperative grounds of urgency so require.
