Heavy Duty Carbon Steel Reducer 500mm ID from China
A concentric reducer fitting made from nonalloy carbon steel for butt welding, with a large end ID of 500 mm tapering to connect differing pipe sizes in industrial water treatment plants. It qualifies for HTS 7307.93.90.40 as an 'other' butt welding fitting of iron/nonalloy steel over 360 mm ID. These are essential for transitioning pipe diameters without welds.

Import Tips
• Measure and document both inlet/outlet IDs precisely, as reducers must average over 360 mm for this code
• Comply with ASME B16.9 standards; include conformance certs to prevent customs holds
• Avoid pitfall of classifying as 'caps'—ensure functional reduction shape, not end closures
