This Order, made under section 269P of the Customs Act 1901, declares that from 07.07.10 the goods described as “valves, non-return, isolating, brass body” (tariff classification 8481.30.00) are subject to Item 50 of Part III of Schedule 4 to the Customs Tariff Act 1995. Mechanically, that applies the Schedule 4 concession to those imported valves (changing the customs duty outcome); importers must classify correctly to obtain the concession and the delegate may revoke the Order under ss269SC or 269SD.
