This Order declares that goods described as “assemblers and joiners and separators and unscrewers, oil and gas tubulars” classified under tariff heading 8479.89.90 are covered by Item 50 of Part III, Schedule 4 to the Customs Tariff Act 1995, effective 15 August 2006. The legal effect is to change the tariff treatment on import for those goods. The decision was made by a delegate of the CEO under section 269P and remains in force until revoked under sections 269SC or 269SD, so importers must treat their entries accordingly.
