In order to ensure that manufacturers across the Union determine similar support periods for comparable products with digital elements, ADCO should publish statistics on the average support periods determined by manufacturers for categories of products with digital elements and issue guidance indicating appropriate support periods for such categories. In addition, with a view to ensuring a harmonised approach across the internal market, the Commission should be able to adopt delegated acts to specify minimum support periods for specific product categories where the data provided by market surveillance authorities suggests that the support periods determined by manufacturers are either systematically not in line with the criteria for determining the support periods as laid down in this Regulation or that manufacturers in different Member States unjustifiably determine different support periods.
