Alloy Steel Weld Neck Flange 150# from Japan
A weld neck flange made of alloy steel (not stainless), with an inside diameter of 8 inches (203 mm), designed for high-pressure piping systems in oil and gas applications. It falls under HTS 7307.91.50.30 as a flange of alloy steel with inside diameter less than 360 mm. The long tapered hub provides strength and reduces stress concentration at the weld.

Import Tips
• Verify alloy steel composition via mill test certificate to confirm non-stainless status; ensure inside diameter measurement is documented as under 360 mm
• Common pitfall: misclassifying as stainless steel which falls under different subheading
