(38)In respect of taxable operations in the domestic market linked to intra-Community trade in goods carried out during the transitional period by taxable persons not established within the territory of the Member State in which the intra-Community acquisition of goods takes place, including chain transactions, it is necessary to provide for simplification measures ensuring equal treatment in all the Member States. To that end, the provisions concerning the taxation system and the person liable for payment of the VAT due in respect of such operations should be harmonised. It is however, necessary to exclude in principle from such arrangements goods that are intended to be supplied at the retail stage.
