Under section 269P of the Customs Act 1901, this Order applies item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 to a specific imported product described as “DISPENSER SYSTEM, SAND, RAIL VEHICLE” (tariff code 8424.30.90), effective 30 September 2010 until revoked under ss.269SC/269SD. Mechanically, it changes the tariff treatment for importers of that specific equipment; the delegate decides application and revocation, and importers must meet documentation and compliance requirements to claim the concession.
