This Order applies a tariff concession (Schedule 4, Item 50) to a specific imported product: hoses used for conveying abrasive fluid, classified at tariff code 4009.31.90. It takes effect from 28 February 2007 and remains in force until revoked under the Customs Act. The practical effect is to change the customs treatment for importers of these hoses: the delegate of the Chief Executive Officer (Wendy Knowles) decides the concession; importers (or their suppliers) are the parties who benefit or see a changed duty outcome.
