This Tariff Concession Order (TCO 0506584) declares that 'valves, ball, subsea' (tariff code 8481.80.90) are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, taking effect 2 June 2005 (s.269P; table). Practically, importers of these subsea ball valves receive the tariff treatment in item 50 until the order is revoked under sections 269SC or 269SD; the delegate records the decision and importers must use the correct tariff classification and supporting documentation.
