This Tariff Concession Order says a specific type of heavy self‑propelled platform transporter (tariff classification 8704.23.00) qualifies for a Schedule 4 tariff concession (item 50), effective 21 May 2010 until revoked. It was made by a delegate of the Chief Executive Officer under the Customs Act. Importers of these machines receive reduced customs duty; the Commonwealth forgoes revenue. The order’s technical limits (weight, bogies, steering, per‑bogie capacity, hydraulic lift) define who benefits and create the compliance and classification boundary for importers and customs.
