(78)In order to safeguard the functioning of the internal market, it is necessary to ensure that packaging from third countries that enters the Union market complies with this Regulation, whether imported as standalone packaging or in association with a packaged product. In particular, it is necessary to ensure that appropriate conformity assessment procedures have been carried out by manufacturers with regard to that packaging. Importers should therefore ensure that the packaging they place on the market complies with those requirements and that documentation drawn up by manufacturers is available for inspection by the competent national authorities.
