This Tariff Concession Order declares that specific parts for funicular railway drive systems (classified at 8431.39.00 and comprising a PLC, variable frequency drive and AC asynchronous motor) are to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies. It operates from 23 December 2010 until revoked under sections 269SC or 269SD of the Customs Act 1901. It therefore alters tariff treatment for importers of those parts and imposes the usual compliance and revocation rules on customs administration.
