This Tariff Concession Order (TCO 0925987) says imported rubber floating hoses used for dredging (classified 4009.42.90) qualify for item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, giving them a tariff concession from 21 July 2009 until revoked under ss 269SC or 269SD (or any date listed). The delegate of the Chief Executive Officer made the declaration under s 269P. Practically, importers of these hoses can claim lower customs duty; the Commonwealth receives less tariff revenue and Customs administers compliance.
