This Tariff Concession Order (TCO) declares that specific parts — “tinplate tungsten coated conductor rolls” classified at tariff line 8543.90.90 — are subject to Schedule 4 item 50 of the Customs Tariff Act 1995, effective 8 November 2006. A delegate of the Commissioner made the decision under section 269P and the Order remains in force until revoked under sections 269SC or 269SD. The practical effect is to change the tariff treatment importers of these parts face, altering import costs and related commercial incentives.
