This instrument grants a tariff concession for imported ventilators (tariff classification 8414.59.90) that are IP44 ingress-protection compliant and emit no more than 75 dB(A) of noise. Made by a delegate under section 269P of the Customs Act 1901, it makes Schedule 4 Item 50 apply to those goods from 10 May 2007 until revoked under sections 269SC or 269SD. Importers of the specified ventilators benefit from the concession; customs officials decide application and revocation, and compliance depends on meeting the technical specifications.
