Seamless Steel Boiler Tube OD 250mm WT 10mm
A seamless tube of non-alloy steel with circular cross-section, outside diameter 250mm and wall thickness 10mm, used in high-pressure boilers for heat transfer. It falls under HTS 7304.39.0048 due to its seamless construction, non-alloy steel material, OD between 190.5-285.8mm, and wall thickness under 12.7mm. These tubes are precision-engineered for structural integrity in industrial heating systems.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of alloy steel exceeding specified limits
Alloy steel tubes shift to 7304.51, changing classification based on chemical composition thresholds.
If welded rather than seamless
Welded pipes of non-alloy steel fall under Chapter 73 heading 7306, distinguished by manufacturing process.
If imported as assembled boiler components
If fitted with flanges or fully integrated into boiler parts, it may classify as machinery parts under 8411.
