Welded Alloy Steel Pipe 6-inch OD
A welded circular tube of alloy steel with an outside diameter of 152.4 mm (6 inches) and wall thickness over 1.65 mm, used for structural piping in construction. It falls under HTS 7306.50.50.70 due to its welded construction, alloy steel material, circular cross-section, and specified diameter range exceeding 114.3 mm but not over 406.4 mm.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If wall thickness under 1.65 mm
Thinner-walled tubes shift to 7306.50.10.00 within the same heading for lighter structural applications.
If seamless rather than welded
Seamless alloy steel tubes fall under Chapter 73 heading 7304, distinguished by manufacturing process.
If other cross-section like square
Non-circular hollow profiles classify under 7306.90, as this subheading specifies circular cross-section.

Import Tips & Compliance
• Verify alloy steel composition meets Chapter 73 definitions and obtain mill test certificates for customs compliance
• Ensure accurate measurement of OD and wall thickness; discrepancies can lead to reclassification or penalties
• Declare country of melt and pour for Section 232 steel tariffs; common pitfall is incomplete documentation
