Under s.269P of the Customs Act 1901 this Order (effective 7 May 2010) declares that specified skid‑mounted slurry batch mixers (Tariff code 8479.82.00) are goods to which Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 applies (revocable under ss.269SC–269SD). Mechanically, the delegate fixes the tariff treatment for those importers; customs officers must apply item 50 on import, so import classification, duty liability and related compliance obligations for those mixers are directly affected.
