1. Without prejudice to Article 19 of Regulation (EU) 2019/1020, where the market surveillance authorities of a Member State have sufficient reason to believe that packaging covered by this Regulation presents a risk to the environment or human health, they shall, without undue delay, carry out an evaluation in relation to the packaging concerned covering all requirements laid down in this Regulation that are relevant to that risk. The relevant economic operators shall cooperate as necessary with the market surveillance authorities.
For the purposes of the first subparagraph, the authorities responsible for the enforcement of this Regulation shall follow up on complaints or reports related to alleged non-compliance of packaging with this Regulation, and verify that the appropriate corrective action has been taken.
Where, in the course of the evaluation carried out pursuant to the first subparagraph, the market surveillance authorities find that the packaging does not comply with the requirements laid down in this Regulation, they shall, without delay, require the relevant economic operator to take appropriate and proportionate corrective measures, within a period prescribed by the market surveillance authorities which is reasonable and commensurate with the nature and, where relevant, the degree of the non-compliance, to bring the packaging into compliance with those requirements.
