Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If welded or ERW construction
Welded casing pipes fall under Chapter 73 heading 7306 for line pipe and casing, not seamless 7304.
If wall thickness 12.7 mm or greater
Thicker wall casings shift to 7304.29.30 subheading based on structural strength requirements.
If made of alloy steel
Alloy steel composition (e.g., chrome-moly) changes classification from nonalloy 7304.29 to 7304.39.

Import Tips & Compliance
• Provide API 5CT certification and mill test reports (MTRs) to verify seamless nonalloy steel composition and mechanical properties
• Ensure accurate measurement documentation for OD (9-5/8") and wall thickness to avoid misclassification into thicker wall subheadings
