Seamless Steel Hydraulic Tubing
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If welded rather than seamless
Welded tubes of nonalloy steel with wall under 4mm fall under Chapter 73 heading for welded pipes.
If made of alloy steel
Alloy steel composition shifts classification to other seamless steel tubes in 7304.19.
If imported as parts of hydraulic systems
If specifically for hydraulic equipment use, may classify as machinery parts rather than generic tubes.

Import Tips & Compliance
• 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
