This Order applies a Schedule 4 tariff concession (Item 50, Part III of the Customs Tariff Act 1995) to imports classified as 6903.90.00 — "LININGS, INDUCTOR, silicon carbide" — effective 29 Oct 2010 under section 269P of the Customs Act 1901, and continuing until revoked under sections 269SC or 269SD. It affects importers (who pay lower customs duty if the concession applies), reduces federal tariff receipts, and creates an incentive to import these linings; the operative decision was made by a CEO delegate (Paul Mercer, signed 17 Jan 2011).
