This order, made under s.269P of the Customs Act 1901, declares that certain import goods — “distributors, air, effluent and/or wastewater reactor” with an aeration header and air lift mixer (tariff classification 8479.89.90) — fall under Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 from 21 April 2008 until revoked (ss.269SC/269SD). It affects importers and suppliers by changing the customs duty treatment for those specifically described goods, decided by a CEO delegate, and therefore alters import costs, compliance paperwork and government revenue exposure.
