7224.90.00.55 - Having a width at least four times the thickness

This HTS category, 7224.90.00.55, specifically covers semi-finished products of other alloy steel that have a rectangular or square cross-section. These products are characterized by a geometric proportion where the width is at least four times greater than the thickness. This definition distinguishes them from other rectangular semi-finished alloy steels within the same broader category.

The key distinguishing factor for classification within this subheading is the dimensional ratio of the cross-section. Sibling categories, such as 7224.90.00.45, cover products where the width is less than four times the thickness. Therefore, precise measurement of these dimensions is crucial for correct classification. The material composition falls under "other alloy steel," encompassing a wide range of steel types beyond those specifically listed in preceding headings.

As this is a leaf node in the HTS classification structure, there are no further subcategories. Classification at this level is determined by the unique characteristic of the width-to-thickness ratio in conjunction with the material being other alloy steel and its semi-finished form of rectangular or square cross-section. Examples of such products might include blooms, billets, or slabs intended for further processing into various steel articles, provided they meet the specified dimensional criteria.
