This Tariff Concession Order applies Item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 to specific pumps (gear-lubrication, for roll grinders; rotary positive-displacement) classified at tariff heading 8413.60.10. It took effect 30 April 2007 and continues until revoked under sections 269SC or 269SD of the Customs Act 1901. The practical effect is to change the tariff treatment that importers of these pumps face (and therefore the duty payable) by making Schedule 4 Item 50 apply to them.
