Import Tips
• Verify the fitting is cast iron or steel via mill test reports to confirm classification under 7307; forged fittings go to 7307.99
• Include pressure ratings and dimensions in documentation to avoid misclassification as flanges or adapters
• Ensure country of origin marking complies with customs rules, as Chinese castings are common and face AD/CVD scrutiny
