This Order, made under s.269P of the Customs Act 1901, declares that polycarbonate chair mats (tariff classification 3926.90.90) are goods to which Part III, Schedule 4, item 50 of the Customs Tariff Act 1995 applies, effective 3 September 2007 until revoked. Mechanically, it changes the customs tariff treatment on import for those specific mats, so importers, their suppliers and Customs administration are the parties directly affected and must apply the listed Schedule 4 treatment when classifying and clearing these goods.
