This Tariff Concession Order (TCO 0812249) declares that cylindrical, gravity‑feed hoppers for a pyrite mill (tariff heading 7309.00.00) are goods to which Part III, Schedule 4, item 50 of the Customs Tariff Act 1995 applies. It takes effect from 12 June 2008 and continues until revoked under sections 269SC or 269SD of the Customs Act 1901, issued under s.269P by a delegate.
Mechanically, the Order makes those specified imports eligible for the Schedule 4 concession identified by item 50. That affects importers (who must classify and claim the concession) and the Commonwealth’s tariff receipts; revocation is administratively possible (s.269SC/s.269SD).
