This Tariff Concession Order (TCO 0927136), made under section 269P of the Customs Act 1901, applies Part III Item 50 of Schedule 4 of the Customs Tariff Act 1995 to alloy-steel butt-weld pipe/tube fittings classified at 7307.93.00. It takes effect from 28 July 2009 and continues until revoked under sections 269SC or 269SD. Mechanically, importers of these fittings may claim the Schedule 4 concession (Item 50); the delegate (Paul Mercer) declares applicability, shifting duty liability for those imports and creating an administrative need to rely on the tariff classification and item number.
