This Order declares that a specific polyethylene terephthalate (PET) homopolymer (Tariff classification 3907.60.00) meeting stated technical criteria is subject to item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 15 July 2005 until revoked. It directly affects importers of that PET grade and the customs administration because it changes the tariff treatment for those goods; compliance requires meeting the polymer specs (intrinsic viscosity 0.73–0.8 dL/g, AA <1 ppm, ASTM 4603) and documentation to claim the concession.
