This Order declares that horizontal decanter centrifuges (tariff classification 8421.19.00) are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 9 May 2008 (under s.269P of the Customs Act 1901). The instrument was made by a delegate of the CEO and stays in force until revoked (ss.269SC/269SD). Importers of these centrifuges are directly affected because the Schedule 4 item governs their tariff treatment; customs officials must apply and can revoke the declaration.
