This Tariff Concession Order (TCO 0802633) applies Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 to parts classed at tariff heading 8417.90.00—specifically skid buttons and end flats for walking‑beam furnaces. The declaration was made under s.269P of the Customs Act 1901, took effect 14 Feb 2008 and remains until revoked (ss.269SC/269SD). Mechanically, it changes the tariff treatment on import: importers of these parts will be charged under the listed Schedule 4 item and must classify and document imports accordingly; a CEO delegate made the decision.
