Overview
This category, HTS 7304.59.80.30, specifically classifies seamless tubes, pipes, and hollow profiles made of iron or steel, excluding cast iron. These articles are characterized by having a circular cross-section and are made from "other alloy steel" that does not fall under specific alloy steel categories defined elsewhere in the tariff. Crucially, the defining physical characteristic for this subcategory is a wall thickness that is less than 12.7 mm.
To distinguish this classification from its siblings, note that HTS 7304.59.80.35 covers similar seamless alloy steel pipes with a wall thickness of 12.7 mm or more but less than 19 mm, while HTS 7304.59.80.40 is for those with a wall thickness of 19 mm or more. All these sibling categories share the common traits of being seamless, having a circular cross-section, and being made of other alloy steel, but the precise wall thickness is the critical differentiator.
As a leaf node within the HTS structure, this category represents the most granular level of classification for this particular type of seamless alloy steel pipe. Therefore, there are no further subcategories. Classification at this level is determined solely by the material (other alloy steel), form (seamless tube, pipe, or hollow profile), cross-section (circular), the previously established diameter range (exceeding 114.3 mm but less than 190.5 mm), and the specific wall thickness being less than 12.7 mm. Examples of goods that might fall here include specialized structural piping or hollow shafts manufactured to tight tolerances with a relatively thin wall.
