Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of malleable cast iron instead of ductile
Malleable fittings are classified separately from ductile fittings within cast iron pipe fittings.
If stainless steel construction
Stainless steel tube fittings fall under different material-specific subheadings.
If sold without attached joints
Fittings lacking pre-attached mechanical or flanged joints are classified as other ductile fittings.

Import Tips & Compliance
• Verify ductile iron composition via mill test reports to confirm classification under cast fittings, avoiding misclassification as wrought steel
• Include joint gasket specifications in documentation, as rubber compression seals must be explicitly noted for customs compliance
• Check for pressure ratings and AWWA standards certification to prevent valuation disputes on specialized municipal fittings
