TCO 0701043 declares that from 18 Jan 2007 certain evaporative coolers (tariff classification 8479.60.00) — programmable-logic-controlled units with primary panel filters at least 50 mm thick and cooling towers — are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies.
That changes the import tariff treatment for affected importers. The decision was made by a delegate of the CEO under s.269P of the Customs Act 1901 and the Order runs until revoked under ss.269SC or 269SD; importers must ensure goods meet the technical description to rely on the Schedule 4 treatment.
