This Order (made under s.269P of the Customs Act 1901) declares that specific audio‑frequency power amplifiers meeting four technical features are eligible for item 50 of Part III of Schedule 4 to the Customs Tariff Act 1995. It operates from 29 October 2008 and continues until revoked under ss.269SC/269SD. Importers of the described amplifiers can claim the Schedule 4 concession (reducing or removing customs duty) but must ensure the goods precisely match the listed description and tariff classification to rely on it.
