Mechanically, the Order (under s.269P, Customs Act 1901) declares that certain trolleys (tariff code 8716.80.00) with both a towing connector and a hydraulic winch lifter (lifting capacity not greater than 250 kg) are goods covered by Schedule 4 item 50, effective 08.03.2011 until revoked (s.269SC/269SD). It affects importers of those trolleys by changing their tariff treatment and thus the duty payable; a delegate of the Chief Executive Officer administers and may revoke the Order, and importers must correctly classify goods to rely on the concession.
