Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If welded longitudinally
Welded line pipe of iron/nonalloy steel shifts to Chapter 73 heading 7305.
If alloy steel with min 0.3% molybdenum
Presence of alloying elements meeting Chapter 72 note thresholds moves to alloy subheadings.
If imported for well completion
End-use as production tubing in oil/gas wells classifies under 7306.19, not transport lines.
