This Tariff Concession Order (made under s.269P of the Customs Act 1901) declares that test benches for common-rail diesel fuel injectors (tariff classification 9031.20.10) are covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 29 June 2010 until revoked. Mechanically, it lets importers claim the Schedule 4 concession (changing the tariff treatment), requires correct classification and documentation by importers, and is a delegated administrative decision revocable under ss.269SC–269SD.
