This Order declares that surface wastewater-treatment aerators (tariff classification 8479.89.90) are eligible for the customs duty concession listed as item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 3 July 2007 until revoked. It was made by a delegate under section 269P of the Customs Act 1901.
Importers of the specified aerators therefore pay lower or no tariff under that Schedule item and the Commonwealth forgoes corresponding tariff revenue. The concession can be revoked under sections 269SC or 269SD; importers must meet the stated classification and timing to claim it.
