7228.30.80.45 - With a diameter or cross section measuring 152 mm or more but not exceeding 228 mm

This HTS category, 7228.30.80.45, specifically classifies "other bars and rods of other alloy steel" that have been hot-rolled, hot-drawn, or extruded, and are not further worked. The defining characteristic of this subcategory is the physical dimension of the bar or rod's cross-section. To fall within this classification, the diameter or cross-section must measure 152 millimeters or more but not exceed 228 millimeters. These products are generally intended for further manufacturing processes in various industries, such as automotive, machinery, or construction.

This category is distinguished from its siblings by its precise dimensional range. For instance, sibling category 7228.30.80.15 covers bars and rods with a cross-section measuring less than 76 mm, while 7228.30.80.41 applies to those measuring 76 mm or more but not exceeding 152 mm. Conversely, 7228.30.80.70 encompasses bars and rods with a cross-section exceeding 228 mm. This meticulous breakdown ensures accurate classification based solely on the physical size of the steel product.

As a leaf node in the HTS structure, this category does not have further subdivisions. Therefore, the classification hinges entirely on the material being "other alloy steel" and meeting the specified cross-sectional dimensions of 152 mm to 228 mm, after undergoing hot-rolling, hot-drawing, or extrusion. The exclusion of further working is also a critical element for classification within this specific sub-heading.
