This Tariff Concession Order applies Part III Schedule 4 item 50 of the Customs Tariff Act 1995 to specified circuit breakers (AC and/or DC; single or multiple pole; ≤400 A; ≤1,000 V AC), effective 30 June 2011. Made by a delegate of the Chief Executive Officer under s269P, it treats qualifying imported goods under the listed Schedule 4 concession until revoked (ss269SC/269SD). Importers must ensure their goods match the technical description to qualify; the concession alters tariff treatment and can affect customs revenue.
