This Order declares that goods described as "MOTORS, DC, ARMOURED" falling under tariff classification 8501.34.00 are covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 2 June 2005 (made under s269P of the Customs Act 1901).
Mechanically, that lets importers claim the Schedule 4 concession (reducing customs duty on those imports); the concession remains until revoked under ss269SC/269SD. Importers must correctly classify goods and follow customs procedures to obtain the benefit.
