Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If drill pipe configuration with tool joints
Same material but if equipped with upset ends/connections, classifies as drill pipe subheading.
If stainless steel bars over 16mm thick
If cross-section exceeds wire definition and not tubular for drilling, shifts to steel bars.
If threaded and coupled at both ends
Fully assembled threaded tubing sets for drilling may enter under pipe fittings heading.

Import Tips & Compliance
• Provide chemical composition analysis proving Duplex stainless (e.g
• 22% Cr) for correct stainless steel heading
• Customs may require proof of seamless manufacture—include hydrostatic test and non-destructive testing reports
