This Order treats oven and afterburner duct parts for continuous paint lines (goods classifiable to tariff item 8417.90.00) as eligible for Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 14 July 2006. It mechanically reduces the tariff payable on those imported parts while in force. Importers of those components benefit; compliance requires correct tariff classification and reliance on the delegate’s administrative decision, and the concession continues until formally revoked.
