This Order (TC 0838649) designates a specific product—by-pass valves for oil and gas wells (tariff code 8481.80.90)—as goods to which Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 applies, effective 6 November 2008 until revoked. The declaration is made by a delegate of the Chief Executive Officer under section 269P of the Customs Act 1901 and therefore changes how those particular valves are treated under the tariff schedule, affecting importers, customs agents and traders who deal in those goods.
