This Tariff Concession Order declares that a specific type of aircraft passenger boarding bridge — telescopic apron-drive bridges with a rotunda, glass‑walled telescopic tunnels and hydraulic elevation — is a good to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies. It operates from 27 September 2007 and continues until revoked. The order changes the tariff treatment on import for manufacturers, suppliers, airport operators and importers; the change is made by a Customs delegate and endures only while the Order remains in force.
