This Tariff Concession Order (TCO 0609672) applies Item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 to specific apron‑feeder parts (head shafts/sprockets; tail shafts/traction wheels) classified at 8431.39.00, effective 1 June 2006 (made under s.269P). It affects importers and customs officials by changing which Schedule 4 treatment those parts receive; the delegate may revoke the order under ss.269SC–269SD, so importers must ensure correct classification and monitor for revocation.
