This Tariff Concession Order (TCO 0910175) declares that U‑tubes for steam boilers made of copper‑aluminium alloy (Customs Tariff classification 7411.29.00) are covered by item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995, with effect from 26 March 2009. (s.269P)
It affects importers of those specific U‑tubes by determining the tariff item—and therefore the duty treatment—applied on import. The order remains in force until revoked under ss.269SC–269SD; administration and classification decisions sit with Customs.
