Grants a tariff concession so imported steel hangers/separators (Tariff 7323.99.00) are treated under Part III, Schedule 4 item 50 of the Customs Tariff Act, effective 25 May 2009 until revoked. Importers of these goods pay the reduced or nil customs duty under that Schedule rather than the standard rate; the concession is made by a Customs delegate under s269P and may be revoked under ss269SC or 269SD. Claiming the concession depends on correct tariff classification and administrative steps by importers.
