This Order applies Part III of Schedule 4 (Item 50) of the Customs Tariff Act 1995 to a specific imported good: a rotary table assembly for an electric submerged arc furnace (including main beam assembly, wheel assemblies, internal gear assembly and vertical shaft), tariff classification 8514.90.00. It takes effect from 10 September 2010 and continues until revoked under ss 269SC or 269SD of the Customs Act 1901 (made by a delegate under s 269P).
Mechanically, the Order changes the tariff treatment that applies to importers of that specific assembly; importers must match the description to obtain the treatment, and the concession can be revoked under the cited Act provisions.
