This Order names certain imported truck parts (tariff classification 8707.90.90) — specifically cabs/cabins and bodies for on‑road trucks with a gross vehicle weight of at least 7.5 tonnes — as goods to which Item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 applies. It takes effect from 17 October 2007 and remains in force until revoked. Mechanically, the instrument changes how those imported parts are treated under the Customs Tariff schedule and therefore affects importers who classify and lodge those goods with Australian Customs.
