Seamless Alloy Steel Boiler Tube 250mm OD from Mexico
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.

Import Tips
• 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
