This Order declares that a specific glass-fabric laminate (three-dimensional interstitial construction, upper and lower decks, conjoining vertical pile threads, silane sizing) classified at tariff code 7019.59.00 is treated as covered by item 50 of Part III, Schedule 4 to the Customs Tariff Act 1995, effective 28 February 2011. Mechanically, it changes customs tariff treatment for importers of that product, affecting who pays duties or gains concessions; the CEO’s delegate may revoke the Order under sections 269SC or 269SD, creating administrative discretion and compliance risk for importers.
