Declares a tariff concession under s.269P of the Customs Act 1901 that applies item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 to specified lighting/signalling goods—vehicle top flashing beacons and vehicle‑mounted telescopic tower lights—effective 16 February 2011 until revoked (ss.269SC/269SD). Importers benefit from reduced tariff treatment; the Commonwealth forgoes corresponding revenue. The decision is taken by a Chief Executive Officer delegate and administration depends on Customs classification, producing concentrated benefits for importers and compliance work for Customs and traders.
