This Tariff Concession Order (TCO 0618735) applies Item 50 in Part III of Schedule 4 of the Customs Tariff Act 1995 to specified parts of a gasholder mechanical seal (classification 8484.20.00), changing their tariff treatment for imports from 22 November 2006 (made under s.269P of the Customs Act 1901).
It affects importers and manufacturers who pay customs duty, Customs officials who administer and may revoke concessions (ss.269SC/269SD), and suppliers of the listed parts because it alters import costs and creates a specific compliance record for those goods.
