This Order applies item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 to alternators classified at 8511.50.90, effective 26 May 2010 and continuing until revoked (ss 269SC/269SD). It was made by a delegate under s 269P. Mechanically, the instrument changes the tariff treatment that importers of those alternators face, creating an incentive to import under that classification, and it imposes a compliance obligation to use the correct tariff classification while exposing importers to revocation risk.
