This Tariff Concession Order applies a Part III Schedule 4 tariff item (shown in Column 2) to a narrowly described class of motor‑drive inverters for a hot strip mill (PLC, >10 kW, DC/AC, variable‑frequency). It takes effect from 14 September 2005 and remains in force until revoked under the Customs Act (ss 269SC/269SD). The practical effect is to change the import tariff treatment for businesses importing these specific inverters, shifting who pays customs duties and imposing classification and compliance obligations on importers.
