Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as tubing rather than casing
Small diameter with EUE often imports as 'tubing' under 7306 series.
If electric resistance welded
ERW construction changes from seamless to welded classification.

Import Tips & Compliance
• EUE 8RD is standard connection—include thread gauge certification
• J55 is lowest API grade; verify no downrating for specific wells
• Commonly dual-classified as tubing; declare primary oil/gas casing use
