This Tariff Concession Order applies item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 to a specific good: ceramic‑covered centre‑press rolls for paper‑making machines (tariff classification 8420.91.00). It takes effect from 17 January 2008 and remains until revoked. Importers of the named goods and the Border/Customs administration are affected because the order changes the tariff treatment that applies to those goods, which can alter duty payable and import compliance requirements.
