This Order (under s.269P, Customs Act 1901) declares certain mining scaling rigs (8430.50.00: hydraulic boom and scaling hammer) to be goods covered by Schedule 4, Part III item 50 of the Customs Tariff Act 1995 from 9 March 2010. Mechanically, qualifying importers get the Schedule 4 concession (reduced/zero duty) for those goods. It affects importers and suppliers, shifts cost from them to the tariff concession regime, and requires correct customs classification; the delegate may revoke the Order under ss.269SC/269SD.
