Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If threaded or coupled
Pipes fitted with threads or couplings for assembly are directed to 7306.30.
If for external diameter over 609.6 mm
Larger diameter LSAW pipes exceed this subheading's size limit and move to 7305.31.
If imported as part of gas compressor sets
When supplied as integral components of machinery like gas turbines, classification shifts to Chapter 84.
