This Tariff Concession Order applies item 50 of Part III of Schedule 4 of the Customs Tariff Act 1995 to a narrowly described class of four‑wheel‑drive concrete mixer trucks (agitator drum 5.5–7.1 m3), effective 07.06.07. Goods matching the tariff classification 8705.40.00 and the description are treated under that Schedule 4 item until the Order is revoked. Practically, importers of those trucks receive the concession (reducing customs duty exposure) and the delegate of the Chief Executive Officer may revoke the Order under ss.269SC/269SD.
