Mechanically, this Order (made under s.269P of the Customs Act 1901) declares that goods described as “segments, tread, earthmover tyre” classified at tariff line 4016.99.00 are treated as goods to which Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 applies, effective 16 January 2007 until revoked (ss.269SC/269SD). This directly affects importers and the Customs administration by changing how those imports are classified for tariff purposes; the decision is taken by a CEO delegate and can alter duty treatment and compliance steps.
