This Tariff Concession Order (TCO 0619387) treats hinged aluminium hatches (Customs Tariff classification 7610.10.00) as falling under item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 5 December 2006. It was made by a delegate under s269P of the Customs Act 1901 and continues until revoked under ss269SC or 269SD. Mechanically, affected importers pay reduced or no customs duty on these goods (subject to correct classification and any conditions), shifting the fiscal effect to the Commonwealth and relying on administrative classification and revocation decisions.
