This Order (made under s.269P of the Customs Act 1901) declares that specified gear wheel sets for air compressors (tariff classification 8483.40.90) are covered by the concession item in Part III of Schedule 4 to the Customs Tariff Act 1995. It takes effect from 23 January 2008 and continues until revoked under ss.269SC or 269SD. Importers (who pay customs charges) are directly affected because the Order changes the tariff treatment of those imported parts; the decision and any revocation are administrative.
