Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lined with rubber or plastic for corrosion protection
Internally coated tubes classify under 7306 as tubes with attached fittings or coatings.
If diameter between 114.3mm and 406.4mm
Size threshold determines subheading—smaller diameters fall under 7305.31.20.
