Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of stainless steel
Stainless steel line pipes are separated into 7306.19.20 based on chromium/nickel content.
If specifically designed as gas cylinders under pressure
Pressurized gas storage cylinders fall under Chapter 84 for machinery, not hollow profiles.
If for use in oil/gas well drilling
Drill pipe or tubing for wells is in 7304, distinguished by well-specific threading and function.
