Ductile Iron Rubber Compression Tee Coupling
Cast ductile iron tee fitting with push-on rubber compression joints on all three ends, used for branching underground sewer or water lines. Classified under HTS 7307.19.30.70 due to its ductile cast construction and attached mechanical rubber compression joints for gasket-sealed connections. Ideal for non-pressurized drainage systems requiring corrosion resistance.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cast iron but for specific tube sizes
Certain cast fittings for tubes under 2 inches may shift to subheadings based on diameter.
If other alloy steel, not ductile cast
Non-ductile cast alloy steel fittings have separate statistical reporting.
If imported as part of complete pump assemblies
Fittings integral to machinery like pumps are classified by end-use apparatus.

Import Tips & Compliance
• Provide hydrostatic test certificates proving leak-proof rubber joint performance to support duty classification
• Label fittings clearly with joint type (push-on) to avoid reclassification as threaded or welded fittings
• Ensure country-of-melt documentation for iron content, as anti-dumping duties may apply to certain origins
