This Order treats a specific ocean oil‑spill containment system (a single‑point inflation boom plus a diesel‑engine hydraulic boom reel with integrated air blower) as eligible for the tariff concession listed at item 50 of Part III of Schedule 4 to the Customs Tariff Act 1995. It takes effect from 8 October 2010 and remains in force until revoked. The practical effect is to change how customs duty applies to imports of that precisely described equipment, affecting importers' costs and incentives to import.
