Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered hollow bars rather than tubing
Semi-finished hollow products not meeting tubing dimensional tolerances classify as hollow bars.
If threaded and supplied with couplings
Tube/casing sets with couplings may classify under 7307 as threaded/assembled fittings.

Import Tips & Compliance
• 13Cr material requires NACE MR0175 compliance documentation for sour service applications
• Exact weight per foot (e.g
• 12.75#) and connection type must match invoice descriptions
• Distinguish from boiler tubes (7304.51) by providing drilling end-use affidavits
