This Order designates viscose rayon yarn (Tariff classification 5510.11.00) as subject to Schedule 4 item 50 tariff treatment from 30 June 2005 until revoked (authority: s.269P of the Customs Act 1901; revocation: ss.269SC/269SD). It affects importers of that specific yarn by changing which tariff item applies to their imports. The mechanical effect is administrative: the CEO’s delegate (Michael Perry) declares the applicable concession and importers must rely on the correct tariff classification and this Order when lodging customs entries.
