Mechanically, this Order declares aluminium composite panels (Tariff 7606.11.00) are subject to Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 from 24 April 2009 until revoked. It affects importers and customs officers: importers can claim the Schedule 4 treatment when lodging entries, and the decision was made by a CEO delegate under s269P of the Customs Act 1901 (revocable under ss269SC–269SD). This changes customs treatment and therefore import cost and compliance steps for the listed goods.
