This Tariff Concession Order applies Schedule 4 item 50 to hydraulically controlled flapper valves (with fail‑safe spring closure) classified at 8481.80.90, changing their customs tariff treatment from 23 March 2009. It affects importers, domestic buyers and customs officers by altering import costs and the paperwork needed for those specific valves.
The Order was made by a delegate under section 269P of the Customs Act 1901 and remains in force until revoked under ss 269SC or 269SD, so administrative decision‑making determines how long the concession operates.
