Seamless Heat-Resisting Steel Furnace Tube
A seamless tube made from heat-resisting alloy steel, designed for high-temperature applications in industrial furnaces. It falls under HTS 7304.59.60.00 due to its seamless construction, circular cross-section, and composition of heat-resisting steel capable of withstanding extreme temperatures without deformation.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically heat-resisting alloy
Standard alloy steel tubes without heat-resisting properties classify under other alloy steel provisions.
If imported as part of heat exchanger assembly
Tubes for specific machinery like heat exchangers may fall under parts of Chapter 84 headings.
If welded rather than seamless
Welded pipes of heat-resisting steel are classified in Chapter 73 heading 7306, not seamless 7304.

Import Tips & Compliance
• Verify chemical composition certificates to confirm heat-resisting steel properties as per ASTM A213 or equivalent standards
• Obtain mill test reports (MTRs) proving seamless manufacturing to avoid reclassification as welded pipes
• Avoid common pitfalls like misdeclaring diameter over 406mm, which shifts to other subheadings
