This Order treats parts for an electromagnetically powered fairground ride — single‑carriage wheeled vehicles with at least ten seats (tariff heading 9508.90.00) — as goods to which Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 applies, effective 23 November 2009 until revoked. Practically, importers of those parts can claim the Schedule 4 concession; the Chief Executive Officer (and delegates) administers and may revoke the concession under the Customs Act (sections 269P, 269SC, 269SD).
