Cold-Drawn Seamless Steel Hydraulic Tube
A seamless tube made from nonalloy steel, cold-drawn to precise tolerances for use in hydraulic systems and cylinders. It falls under HTS 7304.31.60 as a cold-drawn tube of circular cross-section, other than those for boilers, tubes or pipes suitable for drilling, or having a wall thickness of 0.8mm or less.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made from alloy steel
Alloy steel composition (e.g., with chromium or molybdenum exceeding limits) moves classification to the alloy steel subheading.
If welded rather than seamless
Welded construction, even if cold-drawn, falls under Chapter 73 welded pipe headings instead of seamless.
If wall thickness 0.8mm or less
Thin-walled tubes meeting the specific dimension criterion are classified separately from 'other' cold-drawn tubes.

Import Tips & Compliance
• Verify seamless construction via mill test certificates to avoid misclassification as welded under Chapter 73 headings like 7306
• Include chemical composition reports confirming nonalloy steel status to distinguish from alloy steel in 7304.39
• Measure wall thickness and dimensions precisely; tubes ≤0.8mm wall may shift to other subheadings
