7228.50.50.15 - With a diameter or cross section measuring less than 76 mm

This HTS category encompasses bars and rods made from other alloy steels that have undergone cold-forming or cold-finishing. Crucially, these specific items are defined by their physical dimensions, particularly their diameter or cross-sectional measurement. This classification applies exclusively to those bars and rods where this measurement is less than 76 mm. The "other alloy steel" designation indicates steels that do not fall into more specific alloy steel categories but still contain elements beyond iron and carbon in significant quantities.

The defining characteristic of this category, distinguishing it from its siblings, is the precise size threshold of the cross-section. Unlike subcategory 7228.50.50.40, which covers items with a diameter or cross-section measuring 76 mm or more but not exceeding 228 mm, and 7228.50.50.70, which applies to those exceeding 228 mm, this category strictly applies to the smaller dimensions. Therefore, the physical dimension is the primary classification driver at this level.

As this is a leaf node in the HTS structure, there are no further subdivisions under this specific code. Classification within this category is finalized once it is determined that the goods are other alloy steel bars or rods, have been cold-formed or cold-finished, and their diameter or cross-section measures less than 76 mm. Any other characteristics or treatments, if they lead to further refinement in classification, would have been addressed at a higher or a different branch of the tariff schedule.
