Mechanically, this Tariff Concession Order declares that “drives, motor-in-wheel, automated guided vehicle (AGV)” (classified 8501.32.00) are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 11 April 2007. The decision was made by a delegate under s269P of the Customs Act 1901 and remains in force until revoked under ss269SC or 269SD. This makes the Schedule 4 concession available for those specific imported AGV drive units and therefore alters import duty treatment for importers of those goods.
