Mechanically, this Tariff Concession Order (under s.269P of the Customs Act 1901) declares hydraulic presses for wood and/or paper (tariff code 8479.89.90) to be covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, effective 22 May 2007 until revoked under ss.269SC or 269SD. That creates a tariff concession: importers pay lower customs duty where item 50 reduces the rate; the delegate of the CEO (Michael Perry) issued it, and affected businesses must correctly classify imports and monitor for revocation, which changes import costs and sourcing incentives.
