This Order applies Part III item 50 of Schedule 4 to imported dipropylene glycol monomethyl ether (tariff classification 2909.49.00), giving that product the tariff concession specified. It took effect on 11 July 2005 and can be revoked under sections 269SC or 269SD of the Customs Act 1901. Mechanically, the delegate of the CEO made the decision under section 269P; importers gain lower or no tariff, the Commonwealth forgoes revenue, and compliance requires correct tariff classification and reliance on the Order.
