Heavy Weight Alloy Steel Drill Pipe 5-1/2 Inch OD
Heavy weight drill pipe (HWDP) made from seamless alloy steel tubing, 5-1/2 inch outer diameter, used in oil/gas drilling to provide weight on bit and prevent buckling. Falls under HTS 7304.23.60 as 'other drill pipe' of alloy steel, distinct from standard drill pipe due to thicker walls.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of carbon steel rather than alloy
Carbon steel (non-alloy) drill pipe uses 7304.22.60; alloy steel requires minimum specified elements like chromium or molybdenum.
If classified as drill casing/tubing rather than pipe
Pipes have tool joints for rotation; casing lacks them and serves containment, moving to 7304.39 for other iron/steel types.
If when part of gas drilling equipment sets
Integral components of turbodrills or downhole motors classify under Chapter 84 as parts of gas/liquid pumps.

Import Tips & Compliance
• Include detailed specifications showing HWDP design features like upset ends and premium connections for customs verification
• Provide evidence of use in drilling operations (e.g
• purchase orders from drilling contractors) to distinguish from casing/tubing
• Avoid misclassification by confirming seamless manufacture; welded HWDP would go to different headings
