This Tariff Concession Order (TCO 0618438) declares that roller mill parts — roller shells classified under 8474.90.00 — are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 10 November 2006 (made under s269P of the Customs Act 1901). It affects importers of those roller shells because the duty treatment set by Schedule 4 Item 50 now attaches to imports of these goods; the Order can be revoked under ss269SC or 269SD and was made by a delegate of the CEO.
