Mechanically, this Order applies Part III, Schedule 4 item 50 of the Customs Tariff Act 1995 to a specified imported good — “waste separators, single stream” (tariff classification 8479.89.90) — effective 15 Nov 2005 under authority of s269P of the Customs Act 1901, and continuing until revoked (ss269SC/269SD). It changes the tariff treatment that importers face for that equipment, thereby altering customs costs and compliance obligations and leaving revocation and classification disputes to administrative processes.
