Mechanically, this Tariff Concession Order declares that a specific knitted fabric (polyamide or polyester containing 8–55% elastomeric yarn, weighing 110–300 g/m2; tariff classification 6004.10.00) is to receive the tariff treatment set out at Part III, Schedule 4, item 50 of the Customs Tariff Act 1995, effective 11 November 2009. It affects importers and overseas suppliers because it changes the tariff outcome on import; the order was made by a delegate of the Chief Executive Officer and can be revoked under ss.269SC–269SD, so importers must ensure the goods meet the stated composition and weight to qualify.
