This Tariff Concession Order, made under section 269P of the Customs Act 1901, declares that a specific pump (tariff code 8413.60.90 — rotary‑lobe, self‑priming, valveless, elastomer‑coated rotors) qualifies for the Schedule 4, Part III concession item 50 in the Customs Tariff Act 1995, effective 3 April 2009. It affects importers (who may pay lower customs duty) and customs officials (who must apply the concession) and can be revoked under sections 269SC or 269SD, so the concession is administratively reversible.
