This Tariff Concession Order (effective 6 July 2010) declares that a narrowly defined type of DC motor — one with a gearbox, power output not exceeding 100 W, an electric brake and a digital incremental encoder (classified 8501.31.00) — is a good to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies. It changes the customs/tariff treatment and compliance obligations for importers and customs officers for those motors and remains in force until revoked; the exact tariff effect requires consulting Schedule 4 item 50.
