2. By 12 February 2028, the Commission shall adopt implementing acts to establish the methodology for the calculation of the empty space ratio referred to in paragraph 1. That methodology shall take into account the special characteristics of packaging which needs to be placed in an empty space that is large enough to comply with applicable legal requirements or to protect the product, such as, in particular, packaged products of irregular shape, packaging containing more than one sales packaging or product, packaging containing liquid products, packaged products the content of which can easily be damaged and packaged products that can be damaged by larger products due to their small dimensions, and the minimum space on the transport packaging to enable shipment labels to be affixed.
Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 65(2).
