This order restores Tariff Concession Order No. 0509438, reinstituting a customs duty concession for polyethylene terephthalate (PET) copolymer that meets specified lab criteria (intrinsic viscosity 0.75–0.87 dL/g, acetaldehyde <1 ppm, ASTM 4603). The concession is treated as effective from 15 July 2005 and continues until revoked under the Customs Act.
It affects importers and manufacturers who rely on this tariff classification; they must ensure the imported goods meet the technical specifications to qualify. A delegate refused a revocation request under subsections 269SH(5) and 269SC(5).
