Tariff Concession Order 1017212 declares that certain mops (squeeze, flat swivel head, cone-wringing) classified at 9603.90.00 are treated as goods to which Item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 applies, effective 13 April 2010 (under s.269P of the Customs Act 1901). Importers of those mop types receive the Schedule 4 concession (lower import duty); the delegate made the declaration and it remains in force until revoked under ss.269SC/269SD, creating administrative discretion and a fiscal cost to government.
