This Order declares that "solutions, polymaleic acid" classified under tariff heading 3911.90.00 are to which Part III, Schedule 4, item 50 of the Customs Tariff Act 1995 applies, effective 23 Sep 2011 until revoked.
It affects importers of those chemical solutions by changing which tariff item applies (and therefore their customs duty treatment). The concession is administrative: a delegate may revoke it under ss.269SC or 269SD, so importers must ensure correct classification and records to rely on the order.
