This Order (TCO 1007910) declares that “test tree valves” for subsea oil or gas wells (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 12 Feb 2010 and continuing until revoked under ss.269SC–269SD. It changes the tariff treatment that importers and customs officers apply at importation. The decision was made under s.269P by a delegate of the CEO; importers’ costs, clearance steps and compliance obligations may therefore change.
