7304.59.20.45 - Having an outside diameter of 38.1 mm or more but not exceeding 114.3 mm

This HTS category, 7304.59.20.45, specifically classifies seamless tubes, pipes, and hollow profiles made from iron or steel, of other alloy steel, and of a circular cross-section. The defining characteristic of this subcategory is its outside diameter. Goods falling here must have an outside diameter that is 38.1 mm or more but does not exceed 114.3 mm. These products are intended for general use and are not specifically designated for specialized applications like boilers or heat exchangers, which are classified under different subheadings.

To distinguish this category from its siblings, note that 7304.59.20.40 covers similar items with an outside diameter less than 38.1 mm, while 7304.59.20.55 and subsequent sibling categories cover progressively larger diameters exceeding 114.3 mm. This specific range is crucial for accurate classification, ensuring that trade statistics and duty assessments accurately reflect the physical dimensions of the imported or exported goods.

As this node is a leaf node, there are no further subcategories to introduce. Therefore, the focus remains on the precise dimensional criteria of outside diameter (38.1 mm to 114.3 mm) as the sole distinguishing factor within this "Other" classification for alloy steel tubes and pipes of circular cross-section not otherwise specified. Classification decisions within this group rely entirely on adhering to these specified dimensional limits.
