7228.30.80.70 - With a diameter or cross section exceeding 228 mm

This HTS category, 7228.30.80.70, specifically classifies "other bars and rods of other alloy steel" that are not further worked than hot-rolled, hot-drawn, or extruded, and have a diameter or cross-section exceeding 228 mm. These are substantial pieces of alloy steel that fall outside the more common, smaller diameter or cross-section ranges covered by other subheadings. Examples include large, solid cylindrical bars or rectangular bars of significant dimensions, used in heavy industrial applications, manufacturing of large components, or specialized structural purposes where superior strength and alloy properties are paramount.

The defining characteristic of this category is its size threshold. It differentiates itself from sibling categories such as 7228.30.80.15 (less than 76 mm), 7228.30.80.41 (76 mm to 152 mm), and 7228.30.80.45 (152 mm to 228 mm). Only bars and rods with a cross-sectional measurement greater than 228 mm will be classified here. This precise measurement is the sole criterion for distinguishing this category from its direct counterparts at the same hierarchical level.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification decisions at this level are final, resting solely on whether the alloy steel bars or rods meet the material requirements of Chapter 72 and the physical dimension specified. Therefore, for goods falling under this code, careful measurement of the diameter or cross-sectional dimension is crucial for accurate customs declaration.
