This Tariff Concession Order (TCO 0910048) makes a specific class of luffing‑jib electric tower cranes (defined by jib reach and lift capacities) eligible for the tariff treatment listed at item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995. It took effect on 25 March 2009 and remains in force until revoked. The immediate effect is to change the customs tariff outcome for importers of those precisely described cranes; compliance requires matching the technical description at import and depends on a delegate’s declaration under the Customs Act (s.269P).
