Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If outside diameter 215.9 mm or greater
Larger diameter casings shift to separate statistical suffix within the same casing subheading.
If welded rather than seamless
Welded steel pipes for oil/gas drilling fall under Chapter 73 heading for welded tubes.
If made of alloy steel exceeding defined limits
Alloy steel composition moves it to the alloy steel casing provisions.

Import Tips & Compliance
• Obtain API 5CT certification and mill test reports to verify seamless construction and L-80 grade compliance
• Ensure accurate measurement documentation for OD <215.9 mm and wall ≥12.7 mm to avoid misclassification
• Declare exact weight per foot and steel composition to prevent customs disputes on nonalloy status
