Creates a tariff concession for towable, wheeled air compressors (Tariff classification 8414.40.10), declaring them eligible for Schedule 4 item 50 relief from customs duties. Made under s269P of the Customs Act 1901 by a delegate of the CEO, it operates from 3 Aug 2011 until revoked under ss269SC/269SD. Importers gain lower duty on qualifying units and the government forgoes that revenue; compliance requires correctly classifying goods to the order’s description and meeting Customs’ eligibility checks.
