This Order declares that rotor‑pole segments — parts of semi‑autogenous grinding mill motors classified at 8503.00.00 — are goods to which Part III, Schedule 4 Item 50 of the Customs Tariff Act 1995 applies. It takes effect 4 February 2010 and continues until revoked under sections 269SC or 269SD.
Mechanically, the instrument changes the tariff treatment on import for those specific parts. The change is made by a delegate under section 269P; affected importers must rely on the stated tariff classification and entitlement to the Schedule 4 item to claim the concession.
