This Tariff Concession Order designates a specific disc filtration system (polypropylene grooved discs stacked on a spine, inlet and outlet valves, plus a solenoid panel) as eligible for an item in Part III of Schedule 4 to the Customs Tariff Act 1995, so it receives an import tariff concession. It takes effect from 31 May 2011.
The concession benefits importers of the described equipment (lower or no customs duty) and reduces tariff revenue for the Commonwealth; the Order remains in force until revoked under sections 269SC or 269SD of the Customs Act 1901.
