This Tariff Concession Order (TCO 1055951) designates a specific type of torque converter for off‑highway rear dump trucks (lock‑up clutch; stall torque ≤6,170 Nm; cast housing; 2‑section gear pump) as a good to which Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 applies, effective 23 December 2010. Made by a delegate of the CEO under section 269P, it means importers of those exact units can claim the Schedule 4 concession while it remains in force. The concession’s effect depends on the referenced Schedule 4 item and can be ended by revocation under sections 269SC–269SD.
