(7)To cover the additional costs related to the designation of critical ICT third-party service providers that voluntary request to be designated as critical in accordance with Article 31(11) of Regulation (EU) 2022/2554, an additional fixed fee should be established. In order to discourage unfounded requests, such additional fixed fee should not be reimbursed if an ICT third-party service provider withdraws its request during the registration process, nor if the request is rejected.
