Overview
This HTS category, 7304.51.50.15, specifically classifies seamless tubes, pipes, and hollow profiles of iron or steel that are manufactured from other alloy steel, have a circular cross-section, and have undergone cold-drawing or cold-rolling. The defining characteristic for this subcategory is that the steel used in their construction possesses heat-resisting properties, making them suitable for high-temperature applications.
This classification is distinct from its sibling category, 7304.51.50.45, which covers "Other" tubes and pipes of a similar construction (seamless, circular cross-section, other alloy steel, cold-drawn/rolled) but *without* the specific "heat-resisting steel" designation. Therefore, the key differentiator is the material's inherent resistance to elevated temperatures.
As this node represents a leaf in the HTS structure, there are no further subcategories. Classification under 7304.51.50.15 is final, and goods meeting these specific criteria, including being made of heat-resisting steel and suitable for use in boilers, superheaters, heat exchangers, condensers, refining furnaces, and feedwater heaters, will be classified here. Examples would include specialized tubing used in industrial furnaces or high-pressure, high-temperature steam systems.
