This order applies Schedule 4 item 50 tariff treatment to a narrowly described observation-wheel lighting assembly (LED tubing, integral power supply, computer controls, mounting racks) classified at 9405.40.00, effective 23 April 2007. Importers of those assembled units may claim the concession; the CEO's delegate made the declaration under s.269P of the Customs Act 1901 and the order remains in force until revoked under ss.269SC–269SD, so entitlement depends on correct tariff classification and administrative review.
