This Tariff Concession Order (made under s.269P of the Customs Act 1901) designates that thermal regenerative oxidizers for a steel paint line (tariff heading 8419.89.90) with a pure gas volume of at least 60,000 Nm3/hour are subject to item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995, effective 18 November 2005 until revoked. It therefore changes how those specific imported machines are treated under Schedule 4; the declaration was made by a delegate of the CEO and may be revoked under ss.269SC or 269SD.
