Mechanically, this Order (s.269P of the Customs Act 1901) applies Schedule 4 item 50 to imports classed as 8474.80.00 — specified shale briquette presses with a closed list of components — effective 18 March 2010 until revoked (ss.269SC/269SD). It affects importers and suppliers by reducing or removing customs duty on those machines and thus shifts cost from importers to the Commonwealth. That incentive encourages importing that specific press type while creating a need for precise classification and documentary compliance to satisfy the Table description.
