This Order declares that extruded, cross‑linked, foamed polyethylene tubing (tariff heading 3917.21.90) is a good to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 28 April 2005. It was made by a delegate of the Chief Executive Officer under s 269P of the Customs Act 1901 and remains in force until revoked under ss 269SC or 269SD; importers and customs officials must therefore treat affected imports according to that Schedule 4 item when determining tariff treatment.
