This Tariff Concession Order (TCO 0842801) declares that “Kelly bars, drill rig or pile driver” classified at tariff heading 8431.43.00 are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 4 December 2008. It therefore permits concessional tariff treatment for those imported goods. The instrument was made by a delegate of the Chief Executive Officer under s.269P of the Customs Act 1901 and remains in force until revoked under ss.269SC or 269SD; importers must correctly classify goods to rely on the concession.
