This order (under s.269P, Customs Act 1901) declares LED streetlights classified at 9405.40.00 are goods to which item 50 of Part III of Schedule 4 of the Customs Tariff Act 1995 applies, effective 11 July 2008 until revoked (ss.269SC–269SD).
Mechanically, it changes the tariff treatment for importers of those LED streetlights (they receive the concession provided by item 50), shifting import cost and compliance consequences to affected importers and leaving continuation to administrative revocation.
