42mm OD Alloy Steel Seamless Tube
A seamless tube of alloy steel with a 42 mm outside diameter and wall thickness under 6.4 mm, designed for hydraulic systems in machinery. It falls under HTS 7304.59.80.15 due to its circular cross-section, seamless construction from alloy steel, and specified dimensions. Commonly used in high-pressure fluid transfer applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of stainless steel
Stainless steel variants shift to 7304.31 due to specific stainless alloy definitions in Chapter 73 notes.
If welded instead of seamless
Welded construction, even with identical dimensions, classifies under Chapter 73 heading 7306 for welded tubes.
If imported as part of a finished hydraulic cylinder
If assembled into a complete pump or engine part, it may classify under end-use headings like 8412 for machinery parts.

Import Tips & Compliance
• Verify alloy steel composition via mill test certificate to confirm classification under heading 7304
• Ensure precise measurement of OD (38.1-114.3mm) and wall thickness (<6.4mm) for customs declaration
• Avoid misclassification as welded pipes (7306); provide seamless manufacturing proof
