Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of austenitic stainless steel
Austenitic alloys shift to specific stainless headings based on composition, separate from other alloy steel.
If welded instead of seamless
Welded tubes fall under Chapter 73 heading 7306, regardless of alloy or end use.
If not certified for boiler use
General alloy steel tubes without high-temperature suitability classify under 'other' provisions.
