Mechanically, this Order applies an item from Part III of Schedule 4 of the Customs Tariff Act 1995 to imported goods classified 9506.91.00 (described here as “jumping stilts”), effective 29 April 2009, and continuing until revoked under sections 269SC or 269SD of the Customs Act 1901. It therefore changes the customs-tariff treatment of those specific imports. This directly affects importers and customs agents because it alters the tariff treatment they face and the related compliance and clearance requirements.
