Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If outside diameter exceeds 168.3 mm
Drill pipe with larger OD moves to the 7304.29 category for bigger diameter alloy steel drill pipe.
If not specifically designed for drilling operations
Seamless alloy steel tubes not meeting drill pipe specs classified as other seamless pipes under Chapter 73 heading 7306.
If wall thickness ≤9.5 mm
Same drill pipe specs but thinner walls fall into the adjacent subheading for wall thickness not exceeding 9.5 mm.

Import Tips & Compliance
• Provide API 5CT certification and material test certificates (MTC) confirming alloy steel composition and mechanical properties
• Wall thickness must be precisely measured and documented; customs may require ultrasonic testing verification
• Include end-user declaration specifying oil/gas drilling application to avoid reclassification as general tubing
