This Order applies Schedule 4 item 50 of the Customs Tariff Act 1995 to ride-on towing tractors with a draw-bar pull capacity exceeding 5,000 kg, making that tariff concession effective from 31 August 2006 until revoked (s.269P Customs Act 1901; ss.269SC–269SD). It affects importers by changing tariff treatment (so importers pay a different duty if the concession applies); the decision was made by a delegate of the Chief Executive Officer and depends on proving the goods meet the technical description.
