What this does: Creates a tariff concession order under s269P of the Customs Act 1901 that treats a specific imported good — extruded aluminium alloy bars or rods meeting aerospace specification AMS-QQ-A-200/8, temper T6 or T6511 — as falling within Schedule 4, Part III item 50 from 23 April 2007. Who it affects and why it matters: Importers of those exact goods pay duties under the Schedule 4 item rather than the raw tariff line; the decision was made by a delegate of the CEO and remains until revoked (ss269SC/269SD).
