This Tariff Concession Order (under s269P of the Customs Act 1901) declares boom and arm assemblies for mechanical excavators/shovels with shovel capacity of at least 5 m3 (classification 8431.49.90) are covered by Schedule 4, Part III, item 50 from 12 March 2007 until revoked (ss 269SC/269SD). Importers of those parts will receive the tariff treatment in Schedule 4 item 50 rather than the default tariff; the CEO’s delegate (Michael Perry) made the declaration and oversees administrative compliance and revocation.
