This Order declares that a narrowly described class of nickel‑plated brass ball valves (1/4‑turn operation; BSP diameter 6–100 mm; stainless steel handles and lock nuts) are goods to which Item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective from 26 March 2010 until revoked under sections 269SC or 269SD. It affects importers and customs classifiers: only imports matching the listed physical specifications qualify for the Schedule 4 tariff treatment, and the delegate (under s.269P) issued the declaration.
