This Order declares that imported spark‑ignition, internal‑combustion piston‑engine generators (Customs tariff classification 8502.20.00) weighing between 13 kg and 97 kg are subject to the tariff treatment set out at Part III, Schedule 4 item 50, effective 15 November 2011. The declaration was made under s.269P of the Customs Act 1901 and remains in force until revoked under ss.269SC or 269SD. It therefore changes which Schedule 4 concession applies to importers and customs processing for those specific generators.
