This Tariff Concession Order says that certain parts for a "tundish pre-heat station" (ignition burners, nozzles, spark plugs) classified under tariff 8417.90.00 are covered by Part III, Schedule 4 (item 50) of the Customs Tariff Act 1995. It applies from 21 December 2007 until revoked. The delegate of the Chief Executive Officer made the decision under s.269P of the Customs Act 1901. Importers claim the concession by correctly classifying goods; the concession can be removed if revoked under ss.269SC/269SD.
