Alloy Steel Butt-Welding Elbow 400mm ID from China
A large-diameter elbow fitting made from alloy steel (non-stainless) designed for butt-welding into piping systems, with an inside diameter exceeding 360 mm. It is used in high-pressure industrial applications like oil refineries and power plants where strength and corrosion resistance are critical. Classified under 7307.93.90.60 due to its butt-welding design, alloy steel composition excluding stainless, and large internal diameter.

Import Tips
• Verify alloy steel composition via mill test certificates to confirm exclusion of stainless steel for proper HTS classification
• Provide detailed engineering drawings showing inside diameter >360mm and butt-welding ends to avoid misclassification as threaded fittings
