This Tariff Concession Order applies Part III of Schedule 4 (item 50) of the Customs Tariff Act 1995 to a narrowly described class of imported trucks: diesel (compression‑ignition) cab‑chassis, 4×2 drive, with gross vehicle weight between 15 and 17 tonnes. It takes effect from 16 October 2007 and continues until revoked under the cited provisions of the Customs Act 1901. It directly changes the tariff treatment of those specific imported vehicles and is recorded by a delegate of the Chief Executive Officer.
