This Tariff Concession Order (TCO 0805148) declares that specific imported goods described as “TOOLS, RUNNING AND RETRIEVAL, SUBSEA” (tariff heading 8479.89.90) qualify for the Schedule 4, Item 50 concession of the Customs Tariff Act 1995, effective 3 April 2008. The decision is made by a delegate of the Chief Executive Officer under s.269P of the Customs Act 1901. Mechanically, importers of those subsea tools pay the adjusted customs treatment set by the Schedule 4 item; customs enforcement and correct tariff classification determine who benefits and when the concession ends (ss.269SC/269SD).
