This Tariff Concession Order declares that certain dehumidifiers (tariff classification 8479.89.90 that meet a specified extraction rate or have a defroster) are goods to which Item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 applies, effective 28 July 2009. The change alters the customs tariff treatment for those imported dehumidifiers and therefore affects importers and suppliers; it was made by a delegate of the Chief Executive Officer under section 269P and remains until revoked under sections 269SC/269SD.
