This Tariff Concession Order declares that a specific knitted polyester fabric laminated both sides with PVC (meeting exact width, weight and a PVC ink blockout layer requirement) is to which item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 applies. It takes effect 30 November 2007 and continues until revoked. Mechanically, it changes the tariff treatment for importers of that precise product; customs decides application, importers carry compliance costs, and suppliers or buyers may adjust sourcing, pricing or contracts in response.
