Ductile Iron Grooved Reducing Coupling from Germany
A cast ductile iron fitting used to connect pipes of different diameters in grooved piping systems, commonly for fire protection or HVAC applications. It falls under HTS 7307.19.30.85 as other ductile cast iron pipe fittings, not elbows, sleeves, or specifically threaded types. The grooved design allows for mechanical coupling without welding.

Import Tips
• Verify ductile iron composition via material certificates to confirm classification under cast fittings
• Include groove specifications in documentation; mismatches can lead to reclassification as flanges
• Check for anti-dumping duties on Chinese-origin ductile fittings, common pitfall for fire protection imports
