This Tariff Concession Order, made under section 269P of the Customs Act 1901, treats portable, standalone wireless radio-frequency satellite anti-theft alarms (classified at 8531.10.99) as goods to which a Part III Schedule 4 tariff concession applies, effective 7 September 2005 until revoked. It matters to importers and suppliers because it applies a tariff concession to that tariff line, changing the customs duty outcome and creating an incentive to import goods that fit the Order’s description.
