This Tariff Concession Order applies Schedule 4 item 50 (Part III of the Customs Tariff Act 1995) to imported actuator-driven brass (nickel-plated) ball valves classified at tariff heading 8481.80.90, effective 30 May 2008 and continuing until revoked. Mechanically, the Order lowers or removes the tariff for importers of those valves (reducing their import cost and reducing government tariff revenue). It was made by a delegate of the CEO under s.269P of the Customs Act 1901; importers must correctly classify and claim the concession under Customs procedures.
