7228.70 - Angles, shapes and sections:

This HTS category, 7228.70, encompasses angles, shapes, and sections made from "other alloy steel." This means that while the base material is iron and steel, it has been alloyed with other elements beyond the basic composition of standard carbon steel. The term "angles, shapes, and sections" refers to structural forms that are not fully finished bars or rods. These can include L-shapes, T-shapes, U-shapes, and other specifically formed profiles, typically used in construction or manufacturing for their structural integrity.

Distinguishing this category from its siblings, it is important to note that 7228.70 specifically covers these structural profiles. Other categories within 7228 focus on different forms like bars and rods, or specify particular types of alloy steel such as high-speed steel (7228.10) or silico-manganese steel (7228.20). Furthermore, categories like 7228.40 and 7228.50 differentiate based on the primary working process applied to bars and rods, whereas 7228.70 addresses specific cross-sectional shapes.

The subcategories under 7228.70 further refine the classification based on the extent of processing. The option "Hot-rolled, not drilled, not punched and not otherwise advanced" (7228.70.30) applies to angles, shapes, and sections that have undergone hot-rolling but have not been subjected to further mechanical operations like drilling or punching, indicating a less processed state. The "Other" subcategory (7228.70.60.00) would then capture any angles, shapes, and sections of other alloy steel that do not fit the specific criteria of the more detailed subcategory, encompassing those that have been further worked or finished in ways not explicitly defined.
