This Tariff Concession Order (TCO 0616834) applies Part III, Schedule 4 Item 50 of the Customs Tariff Act 1995 to AC electric generators (tariff code 8502.13.90) with output greater than 375 kVA, effective 7 September 2006. It grants those imports the specified tariff treatment until revoked. Importers of these large generators receive the concession; Customs delegates make and may revoke the order under s.269P (grant) and ss.269SC/269SD (revocation), so accurate tariff classification and recordkeeping are required.
