More Specific Codes
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 not specifically for oil/gas drilling
General seamless steel tubes not dedicated to drilling casing fall under other seamless tubes headings.
If made of alloy steel
Casing of alloy steel (with specific alloying elements exceeding nonalloy thresholds) shifts to the alloy steel subheading.
If welded rather than seamless
Welded casing, even if threaded and for drilling, classifies under welded tubes/pipes in 7304.39.

Import Tips & Compliance
• Verify API 5CT certification and provide mill test reports (MTRs) to confirm seamless construction and J55 grade nonalloy steel composition
• Ensure threading specifications match API standards; mismatched threads may lead to reclassification or customs delays
• Include end-user declaration specifying oil/gas drilling use to avoid misclassification as general pipe under 7304.19
