This Tariff Concession Order declares that goods described as “debris caps, subsea, oil and gas well” (Customs classification 8479.89.90) are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies. It takes effect from 17 April 2008 and continues until revoked under ss.269SC or 269SD. Mechanically, the Order changes how those specific imports are treated under the Customs Tariff (which affects duty treatment and concession eligibility); the decision was made by a delegate of the CEO under s.269P.
