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 stainless steel
Stainless steel variants classify under the stainless steel subheading within the same tubing category.
If used for oil/gas line pipe rather than drilling tubing
Line pipe for conveying oil/gas falls under Chapter 73 headings for welded or seamless line pipe, not drilling-specific tubing.
If not specifically for oil or gas drilling
Seamless alloy steel tubes not designated for drilling applications move to other seamless tubes headings.

Import Tips & Compliance
• Verify alloy steel composition meets 'other alloy steel' criteria (not stainless or high-strength low-alloy) with mill test certificates
• Provide API 5CT certification documentation to confirm suitability for oil/gas drilling applications
• Avoid misclassification by ensuring no external seams; inspect for cold-formed wire exceeding 16mm dimension per Chapter 73 notes
