This order declares that valves described as “VALVES, VENT, BLAST FURNACE” (tariff classification 8481.40.00) are to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, making them eligible for the Schedule 4 concession. It takes effect from 12 April 2007. Importers benefit from reduced or zero tariff on these specific goods, the delegate of the CEO made the order (s.269P), and it can be revoked under ss.269SC–269SD, so correct classification and records are required to claim the concession.
