This Tariff Concession Order declares that a specific type of HDPE single‑screw extruder (with bimetallic barrels and grooved haul‑in bushes) is subject to Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 1 November 2006 until revoked (s.269P; ss.269SC/269SD). It changes the tariff treatment of imports fitting that exact description. The declaration was made by a delegate of the CEO and therefore directly affects importers and the customs administration by altering how these machines are classified for tariff purposes.
