Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically for listed high-pressure uses
Welded alloy tubes over 1.65 mm wall but for general conveyance of liquids/gases classify under other subheadings.
If of stainless steel and supplied as tube fittings
Stainless steel tube fittings or bends for boilers/heat exchangers fall under Chapter 73 heading 7307.
If imported as part of a complete heat exchanger assembly
Parts of heat exchange units are classified with the machinery in 8419, not as separate tubes.

Import Tips & Compliance
• Provide heat transfer performance specs and end-use affidavits to confirm heat exchanger suitability
• Cold-drawn finish requires documentation; otherwise, it might be misclassified as hot-finished
• Check for pressure ratings; tubes not rated for high-pressure service may go to general tube headings
