This Order under s.269P of the Customs Act 1901 applies item 50 (Part III, Schedule 4, Customs Tariff Act 1995) to goods described as “cooling towers, alumina plant” (classification 8419.89.90), effective 22 March 2006 until revoked (ss.269SC/269SD).
Mechanically, the decision (made by a CEO delegate, Paul Mercer) changes the tariff treatment on imports of those cooling towers so importers face the tariff outcome set by Schedule 4 rather than the default rate; compliance requires correct classification and observance of revocation rules.
