This order declares that a "towed flexible barge discharge system" — defined as a barge together with control panels, piping and a sea anchor — is covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 2 December 2008. Mechanically, it changes the tariff treatment that applies to imports of that specifically described equipment. The decision is made by a delegate of the CEO under s269P of the Customs Act 1901 and remains until revoked under ss269SC/269SD; primary effects fall on importers, customs administration and suppliers deciding whether to import under the specified classification.
