This Tariff Concession Order (TCO 1137365) applies item 50 of Part III, Schedule 4 of the Customs Tariff Act 1995 to specified metal parts for a “walking bridge” (cross beams; crane, deck and tie beams; various bracing; pile sleeves and pile top hats) classified at 7308.10.00, effective 8 Nov 2011 until revoked.
Mechanically, importers claiming the concession pay lower or no customs duty for those listed parts; the delegate of the Chief Executive Officer authorises and may revoke the order. Importers must correctly classify goods and claim the concession, creating a modest administrative compliance requirement.
