Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If welded or electric resistance welded
Welded tubes of circular cross-section fall under Chapter 73 heading 7306, not seamless 7304.
If made of alloy steel
Alloy steel composition (e.g., chromium >0.3%) shifts to 7304.41 subheadings.
If When imported as assembled cylinder component for specific machinery.

Import Tips & Compliance
• Verify seamless construction via mill test certificate; welded tubes classify under 7306
• Measure OD precisely (38.1-114.3mm) and wall thickness (<6.4mm) for correct subheading
• Include material cert confirming nonalloy steel to avoid alloy steel headings (7304.41+)
