This Order declares that certain filtration machines (Customs Tariff 8421.29.00) — specified as containing ceramic membrane cartridges, pumps and electric motors — are to be treated as goods covered by Schedule 4, Part III item 50, effective 23 November 2011. Mechanically, it confers the tariff concession set out in that Schedule until revoked under sections 269SC or 269SD of the Customs Act 1901. A delegate of the CEO issued the order; importers of these machines receive the Schedule 4 tariff outcome and must meet the relevant classification and administrative requirements.
