Applies Schedule 4 Item 50 of the Customs Tariff Act 1995 to imported "Plant, Desanding" (tariff code 8474.10.00), declaring those goods eligible for the specified tariff concession. The declaration is made by a delegate of the CEO under s.269P (Wendy Knowles) and takes effect from 11 April 2007 until revoked under ss.269SC or 269SD or any date specified in the order. This changes the tariff treatment faced by importers of the listed desanding plant and therefore affects their import costs and sourcing decisions.
