This order declares a specific programmable cutting machine for expanded polystyrene blocks (heated oscillating wires, conveyor, and minimum cutting dimensions) to be eligible for the concessional tariff treatment in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 2 December 2009. It therefore changes how customs duty is applied to that exact machine description. Importers of that machine stand to pay the concessional rate; customs officials apply the Schedule 4 item; the delegate can revoke the order under the cited Customs Act provisions.
