This Tariff Concession Order makes item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 apply to grinding and polishing machines for concrete, granite, marble or terrazzo (tariff classification 8464.20.00). It took effect on 11 August 2008 and remains in force until revoked.
Mechanically, the Order changes how those imported machines are treated under the customs tariff, so it primarily affects importers and businesses buying such machines and the customs administration that applies or revokes the concession.
