Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If outside diameter between 168.3-323.9 mm
Larger OD drill pipe shifts to 7304.23.40 statistical suffix for medium diameter range.
If imported in random lengths without threading
Unthreaded seamless tubes may classify as other alloy steel pipes if not drill-specific.
If imported as complete drill string component
Assembled with other drilling parts may classify as parts of oil/gas drilling machinery.

Import Tips & Compliance
• Proprietary grade qualification packages from manufacturer required for non-standard API grades
• Collapse and burst test data must accompany shipment for customs verification of pressure ratings
• Avoid generic 'steel tube' descriptions; use specific 'OIL DRILLING TUBING' nomenclature
