This Order, made under s.269P of the Customs Act 1901, applies the tariff concession item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 to liquid‑nitrogen‑cooled coolers (tariff classification 8419.50.90), effective 28 Dec 2006 and continuing until revoked under ss.269SC/269SD. Mechanically, it changes how these imported coolers are treated at customs (making them eligible for the listed Schedule 4 concession), so importers stand to pay the tariff rate set by that concession; the decision was made by a CEO delegate (Michael Perry).
