This Order (made under s.269P of the Customs Act 1901) grants a tariff concession for a narrowly described nylon backpack cover (specified features and weight not greater than 150 g), treating it as subject to the Item in Part III of Schedule 4 to the Customs Tariff Act 1995. It operates from 24 June 2011 until revoked. Mechanically, importers of those specific covers benefit from the Schedule 4 concession (reducing or removing customs duty) if the goods match the precise description and tariff classification.
