Mechanically, this Tariff Concession Order (made under s.269P of the Customs Act 1901) applies an item in Part III of Schedule 4 of the Customs Tariff Act 1995 to specified goods described as “light assemblies, gaming tower illumination” (lamps, lamp bases, plugs), effective 17 August 2005. It directly affects importers of those components by changing their tariff treatment (the Schedule 4 item governs duty application). The order is issued by a CEO delegate and remains in force until revoked under ss.269SC–269SD or a specified end date.
