This Tariff Concession Order applies item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 to goods described as “recirculators and/or heat exchangers, hydraulic power, walking beam furnace” (tariff classification 8419.50.90), effective 16 Aug 2005 until revoked under ss.269SC/269SD of the Customs Act 1901.
Mechanically, the order changes the tariff treatment that importers of these parts face; the decision and any revocation were taken by a CEO delegate under s.269P, so customs administration controls application and timing.
