This Tariff Concession Order (TCO 0716533) declares that certain centrifugal fans (classification 8414.59.90; forward‑curve impellers, external‑rotor motors, speed ≥700 rpm) are goods to which item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 applies, effective 28 September 2007 (s.269P; Schedule 4 Pt III item 50).
Importers of those fans are the primary parties affected because the order changes how those goods are treated under the Customs Tariff Act and therefore the tariff/compliance outcome tied to that classification; the order remains in force until revoked (ss.269SC–269SD).
