This Order, made under section 269P of the Customs Act 1901, declares that amphibious harvesters and cleaners classified at tariff line 8705.90.00 are goods to which Item 50 of Schedule 4 to the Customs Tariff Act 1995 applies, effective 4 December 2006 until revoked. Importers of those machines are directly affected because the Order changes their tariff treatment (whatever entitlement Item 50 provides), creating an administrative requirement to claim the classification and exposing the import transaction to delegate review and possible revocation under ss 269SC/269SD.
