This Order grants a tariff concession for stainless‑steel cryogenic liquefied natural gas tanks (tariff classification 7311.00.00), so qualifying imports attract Schedule 4 item 50 treatment from 4 June 2008 until revoked. It affects importers of those tanks, customs administration and competing domestic suppliers by changing import costs and incentives. The declaration was made by a delegate under section 269P and may be revoked under ss.269SC or 269SD; importers must ensure correct classification to claim the concession.
