This Order (made under s.269P of the Customs Act 1901) declares that specific parts — rotors for AC synchronous motors classified at tariff heading 8503.00.00 that weigh at least 20,000 kg and are at least 4,700 mm long — are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 28 March 2007. Mechanically, it attaches the Schedule 4 tariff treatment to those imports; the CEO’s delegate makes the declaration and it remains in force until revoked (ss.269SC/269SD).
