This Order, made under section 269P of the Customs Act 1901, declares that specific heavy-duty motor‑drive converters for hot‑strip mills (with a programmable logic controller and power rating >450 kW) are covered by Schedule 4 tariff concession item 50, effective 13 September 2005 until revoked under sections 269SC/269SD or any specified expiry. Mechanically, it lowers the customs duty applicable to those exact imported goods, shifting classification and compliance responsibility to importers and Customs and creating an incentive to import that precise product specification.
