Mechanically, this Order (made under s.269P of the Customs Act 1901) declares that goods classified at tariff code 8437.10.00 — “round and long grain separating machines” — are to which item 50 of Part III of Schedule 4 to the Customs Tariff Act 1995 applies from 7 December 2009 until revoked under ss.269SC/269SD. The change affects importers and Customs administration: importers must classify these machines under 8437.10.00 to obtain the treatment item 50 confers, and the delegate (Wendy Knowles) exercised the authority to make that designation.
