This Order declares that "liner hangers, expandable, oil and gas exploration and production" classified at 8479.89.90 are goods to which Item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 applies. It takes effect from 27 March 2009 and continues until revoked under sections 269SC or 269SD. It affects importers of those goods by changing their tariff treatment (and therefore the duties payable). The declaration was made by a delegate of the Chief Executive Officer under section 269P.
