This Tariff Concession Order, made under section 269P of the Customs Act 1901, declares that specific mixers and batchers used for terrazzo and/or cement tiles (with dosers and planetary mixers), classified at 8474.39.00, are goods to which Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 applies, effective 3 April 2007 until revoked. Mechanically, that links those imported machines to the listed Schedule 4 item and thus alters their tariff treatment; a delegate issued the order and revocation is governed by ss 269SC–269SD.
