Seamless Steel Hydraulic Tubing from China
Thin-walled seamless tubes of nonalloy steel used in hydraulic systems for machinery and equipment. These pipes have a wall thickness under 4 mm and are classified under HTS 7304.90.50.00 due to their seamless construction from iron or nonalloy steel, distinguishing them from welded pipes.

Import Tips
• Verify seamless production method via mill test certificates to avoid misclassification as welded pipes under 7306
• Ensure wall thickness documentation is precise, as 4mm threshold separates from thicker HTS 7304.90.30.00
• Label with exact steel composition to confirm nonalloy status and prevent alloy steel duties under 7304.19
