This Order makes certain DC circuit breakers (rated voltage over 1,000 V up to 1,200 V and rated current no greater than 125 A) subject to Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 14 October 2011 until revoked. Importers, manufacturers and Customs are affected because the Order changes the tariff treatment of a narrowly defined product class, altering the cost of importing those specific breakers and creating eligibility and compliance requirements for import entries.
