This Tariff Concession Order treats specified absorbent, cylindrical roll sleeves and roll blocks (a listed set of component types) as goods covered by Part III, Schedule 4 item 50 of the Customs Tariff Act 1995, effective 4 January 2010. Mechanically, that classification makes the listed goods eligible for the tariff concession in that Schedule item until revoked under the Customs Act. It affects importers of those specific roll components (who would pay lower customs duty) and is made by a delegate of the CEO under s.269P of the Customs Act 1901.
