This order, made by a delegate under s.269P of the Customs Act 1901, declares that “transformer assembly platforms, air cushioned, height adjustable” (Tariff subheading 8428.90.00) qualify for the Schedule 4 concession Item 50 from 17 June 2011 and continues until revoked under ss.269SC/269SD. Importers of these specific platforms receive the tariff concession (reducing duties paid); the delegate determines eligibility. The change matters because it alters import costs for those goods and can influence sourcing and import timing.
