This Order, made under s.269P of the Customs Act 1901 by a delegate of the CEO, declares that certain blast-furnace dust-discharger assemblies (tariff heading 8428.90.00) are goods to which an item in Part III of Schedule 4 to the Customs Tariff Act 1995 (Item 50) applies, effective 24 January 2007 and continuing until revoked (see ss.269SC–269SD). Mechanically, it changes the tariff treatment of those imported assemblies. It affects importers and suppliers (who must classify and document goods correctly) and gives Customs discretion to apply or revoke the concession.
