This Order (TCO 0802362) declares that “parts, transmission power line, being steel towers” (tariff heading 7308.20.00) are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 11.10.07 (under s269P of the Customs Act 1901). It benefits importers by applying a tariff concession (reducing import duty) and therefore reduces customs revenue; it depends on correct tariff classification, can be revoked by the delegate under ss269SC/269SD, and creates an incentive to import those steel towers.
