This Order declares that parts for fire alarm systems (classified at tariff heading 8531.90.90) are to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, making those imported parts eligible for the listed tariff concession from 05.06.09 until revoked. The declaration is made under s.269P of the Customs Act 1901 by a delegate of the Chief Executive Officer (Wendy Knowles) and can be revoked under ss.269SC or 269SD. Importers are the primary parties affected because the Order changes the customs duty treatment and imposes the administrative steps needed to claim the concession.
