This order (effective 16 Apr 2008) declares hammer mills and vibrating screens for plant, food or chemical use (tariff code 8479.82.00) to be goods covered by item 50 of Schedule 4 to the Customs Tariff Act 1995, creating a tariff concession. It was made by a delegate under s.269P of the Customs Act 1901 and remains in force until revoked under ss.269SC/269SD. Importers who classify these machines under 8479.82.00 can rely on the concession (reducing customs duty); the Commonwealth forgoes the corresponding tariff revenue and customs must verify classification.
