This Tariff Concession Order declares that fibreglass reinforced plastic cooling-tower fanstacks (tariff 3926.90.90) are covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 9 Dec 2008. It was made by a delegate under s.269P of the Customs Act 1901.
Mechanically, importers receive the tariff concession (reducing or removing import duty), the Commonwealth forgoes that revenue, customs apply the concession only on correct classification and documentation, and the order can be revoked under ss.269SC–269SD, so importers face revocation risk.
