Seamless Alloy Steel Boiler Tube 250mm OD
A seamless tube made from alloy steel with a circular cross-section, outside diameter of 250 mm, and wall thickness of 10 mm, designed for high-pressure boiler applications. It falls under HTS 7304.59.80.45 due to its seamless construction, alloy steel material, specified OD range (190.5-285.8 mm), and thin wall less than 12.7 mm. Commonly used in industrial steam generation systems.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of carbon steel rather than alloy steel
Carbon steel seamless tubes (not alloy) fall under 7304.51, shifting from alloy-specific subheading.
If welded instead of seamless
Welded alloy steel pipes of similar dimensions classify under Chapter 73 heading 7306 for welded types.
If outside diameter exceeds 285.8 mm
Larger OD seamless alloy tubes go to 7304.39, outside the 190.5-285.8 mm statistical range.

Import Tips & Compliance
• Verify seamless construction via mill test certificate; welded tubes classify under 7305/7306
• Provide material composition analysis to confirm 'other alloy steel' (e.g
• >1.65% Mn or specific alloying elements)
• Measure OD precisely (190.5-285.8 mm range) and wall thickness (<12.7 mm) to match statistical suffix
