Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If wall thickness 12.7 mm or greater
Thicker-walled casing (≥0.5 inches) moves to 7304.29.10 subheading based explicitly on wall thickness criterion.
If outside diameter exceeds 406.4 mm
Larger OD casing (e.g., 16-inch) falls outside this subheading's range and enters 7304.59 for bigger diameters.
If imported assembled into gas compressors
When incorporated as a component in machinery like gas compressors, it may classify under Chapter 84 as a parts rather than standalone pipe.
