This Tariff Concession Order treats a narrowly described polyester scrim (thermoplastic-coated yarn, not more than 2×2 yarns/cm and not more than 12 gsm) as falling within item 50 of Part III of Schedule 4 to the Customs Tariff Act 1995, effective 16 September 2005 until revoked. Mechanically, it changes the tariff treatment for that exact product and so affects importers, customs brokers and manufacturers by altering import duty exposure and administrative treatment (revocation is via sections 269SC or 269SD).
