This Tariff Concession Order declares specific Rotolock valves (tariff classification 8481.80.90) are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 4 November 2009 until revoked.
It therefore changes the tariff treatment that importers and customs officers must apply to those valves; qualification depends on the valve meeting the technical description (single rotating lock seal joint, at least two access ports with seal cap, inlet 12.7–57.15 mm). The Order is made under s.269P of the Customs Act 1901 by a CEO delegate.
