TCO 1014802 declares certain rotor assemblies for dump‑truck wheel drives (tariff heading 8503.00.00) to be covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 25 March 2010. Mechanically, that makes those imported parts eligible for the Schedule 4 concession rather than the standard tariff. Importers therefore face lower customs duty; the CEO’s delegate issued the order under s.269P and it may be revoked under ss.269SC–269SD. Use of the concession requires matching the goods to the exact description and tariff code.
