This Tariff Concession Order, made under s.269P of the Customs Act 1901, declares that hydraulic subsea valve actuators (tariff classification 8412.29.00) are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies. It takes effect from 16 March 2006 and remains in force until revoked under ss.269SC or 269SD. Importers of the specified actuators and customs officials are the primary parties affected because the Order fixes the Schedule 4 treatment that governs their tariff position.
