This Tariff Concession Order declares that certain blast-furnace parts (axial expansion joints and bellows) classified at tariff heading 8307.10.00 are covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 27 November 2006 until revoked under sections 269SC or 269SD. It was made by a delegate under section 269P (Wendy Knowles). Importers and customs officers must apply the Schedule 4 treatment to these parts; the concession can be administratively revoked, so classification and claiming behaviour matter.
