This Order applies a Schedule 4 tariff concession (Item 50) to imported trucks described as compression‑ignition‑engine (diesel), single or dual cab‑chassis, with gross vehicle weight over 3.5 tonnes but not exceeding 5 tonnes (Tariff code 8704.21.10). It took effect 8 Nov 2010 and continues until revoked. It chiefly affects importers of those trucks by changing the tariff treatment; the concession was declared by a CEO delegate under the Customs Act and requires correct tariff classification to rely on it.
