Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If seamless instead of welded
Seamless tubes of alloy steel for boiler use are classified in heading 7304, not welded tubes in 7306.
If wall thickness under 1.65 mm
Thinner-walled welded alloy steel tubes, even for boilers, fall under the subheading for walls less than 1.65 mm.
If made of stainless steel with specific composition
Certain stainless steel compositions are directed to 7306.40 for welded circular tubes over 1.65 mm wall.

Import Tips & Compliance
• Obtain material test certificates (MTC) confirming alloy composition and ASME compliance to avoid reclassification
• Ensure end-user documentation proves suitability for boilers or heat exchangers, as general-purpose tubes fall elsewhere
• Verify wall thickness measurement ≥1.65 mm; thinner walls shift to other subheadings
