Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported with loose tool joints or wear bands
Accessories and replacement parts for drill pipe classified under other tube fittings.
If carbon steel construction instead of alloy
Non-alloy steel HWDP classifies under 7304.29 for carbon steel drill pipe.
If when imported as complete bottom hole assembly part
Specialized BHA components may classify as parts of drilling rigs rather than pipe.

Import Tips & Compliance
• Upset end dimensions and weld bevel specs must be documented for HWDP identification
• Hardness testing (Rockwell) certification required for premium weight material grades
• Distinguish from regular drill pipe via 'HEAVY WEIGHT' marking and technical specifications
