(24)Specific industry sectors may establish networks to facilitate exchange of data and bring together expertise in the evaluation of information, test data, weight of evidence determinations and bridging principles. Such networks may support manufacturers, importers and downstream users within those industry sectors, and in particular small and medium-sized enterprises (SMEs) in the fulfilment of their obligations under this Regulation. Those networks may also be used to exchange information and best practices with a view to simplifying fulfilment of the notification obligations. Suppliers making use of such support should remain fully responsible for the fulfilment of their classification, labelling and packaging responsibilities under this Regulation.
