This Order, made under section 269P of the Customs Act 1901 by a delegate of the Chief Executive Officer, declares that the listed goods — “REACTORS, ACTIVE FRONT END, comprising three single phase reactors” (tariff classification 8504.50.90) — are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, with effect from 14 December 2007. It changes the import treatment for those specific goods and therefore primarily affects importers and customs administration until revoked under sections 269SC or 269SD.
