This Tariff Concession Order declares that specific loose‑leaf binder/file fittings (back plate rings, lever arches, back plates, compressor bars, finger rings, slots, clips) classified to tariff heading 8305.10.00 are covered by Schedule 4, Part III, item 50 from 22 August 2007 until revoked. It affects importers of those components by changing their customs treatment (reducing or removing duty as the Schedule provides). The declaration is made under s.269P of the Customs Act 1901 and can be revoked administratively under ss.269SC/269SD, so importers must ensure correct classification and monitor for revocation.
