This Tariff Concession Order (TCO 1009368), made under section 269P of the Customs Act 1901, declares that a specific type of valve (electrical directional control pressure‑regulating valves comprising force control solenoids and a valve hydraulic module, classified at 8481.80.90) is subject to item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 22 February 2010 until revoked. Mechanically, it changes the tariff treatment applied at import for those goods, so importers and customs officials must apply the Schedule 4 item and meet the Order’s precise product description.
