Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other stainless steel but welded
Welding process removes it from seamless heading 7304 to welded heading 7306.
If imported as fabricated kiln parts
Pre-bent or machined into specific kiln components becomes fabricated steel parts.
If structural mechanical tubing use
Intended for mechanical/structural applications vs. pressure piping changes statistical reporting.
