7228.50.50.70 - With a diameter or cross section exceeding 228 mm

This HTS category, 7228.50.50.70, specifically classifies "other bars and rods of other alloy steel" that have undergone cold-forming or cold-finishing, and possess a diameter or cross-sectional dimension *exceeding 228 millimeters*. These are essentially large-diameter or large-profile alloy steel bars and rods, distinct from their smaller counterparts. The material is classified as "other alloy steel," meaning it contains elements beyond iron and carbon to impart specific properties, but does not meet the criteria for special alloy steels as defined in Note 1(f) to Chapter 72.

This category is distinguished from its siblings primarily by its substantial physical dimensions. While 7228.50.50.15 covers bars and rods with diameters or cross-sections less than 76 mm, and 7228.50.50.40 encompasses those measuring 76 mm or more but not exceeding 228 mm, this node captures only those exceeding the 228 mm threshold. The "other" designation at this level signifies that these bars and rods do not fall under any more specific subheadings within the 7228.50.50 grouping.

As this is a leaf node within the HTS, there are no further subcategories. Classification under 7228.50.50.70 is determined solely by the material being "other alloy steel," having been cold-formed or cold-finished, and crucially, having a diameter or cross-section greater than 228 mm. Practical examples might include very large diameter alloy steel shafts for heavy machinery, substantial structural components, or oversized billets destined for further processing in large-scale industrial applications.
