Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of stainless steel
Stainless steel casing shifts to 7306.19 due to alloy composition exceeding non-alloy limits.
If seamless construction
Seamless pipes for drilling fall under Chapter 73 heading 7304, not welded/open seamed types.
If used for drilling water wells
Casing for non-oil/gas drilling (e.g., water/geothermal) classified under welded tubes of iron/steel.

Import Tips & Compliance
• Verify API 5CT certification and grade markings (J55) on each pipe length for customs compliance
• Provide mill test certificates showing chemical composition to confirm non-alloy steel classification
• Avoid misclassification as seamless tubing (7304) by documenting welded construction and threaded couplings
