This Order treats a narrowly described class of electric, programmable-logic-controlled locomotives (Customs Tariff heading 8601.10.00) as falling under item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 17 June 2009 (s.269P; Table). Practically, importers of those locomotives receive the Schedule 4 tariff concession (reducing or removing customs duty), subject to revocation under ss.269SC–269SD. The concession changes import costs and therefore affects price and procurement choices for buyers and suppliers.
