This Order treats axial fans with the specified physical and protection features (tariff classification 8414.59.90) as goods eligible for a Schedule 4 concession (Part III item 50), effective 8 December 2009 until revoked.
Importers of those fans can claim reduced customs duty if the goods meet the description; the concession is administered by a delegate of the CEO under s269P of the Customs Act 1901 and may be revoked under ss269SC or 269SD, so importers must ensure correct classification and records to rely on it.
