7214.91.00 - Of rectangular (other than square) cross-section

This HTS category, 7214.91.00, pertains to other bars and rods of iron or non-alloy steel that are not further worked than forged, hot-rolled, hot-drawn, or hot-extruded. Crucially, these articles must have a rectangular cross-section that is not square. This excludes items with a square profile, which would fall under a different classification. The classification applies to goods that have undergone these primary hot working processes but have not been subjected to more advanced shaping or finishing beyond being twisted after rolling.

Distinguishing this category from its sibling, 7214.99.00 ("Other"), is the explicit requirement of a non-square rectangular cross-section. While 7214.99.00 covers other bars and rods that do not meet the specific profile defined here or within other subheadings, 7214.91.00 is dedicated to the rectangular forms. This ensures that items with this particular geometric characteristic are accurately categorized.

Further subdivisions within this category are determined by the carbon content of the iron or steel. The subcategories are established to differentiate based on critical metallurgical properties that influence the material's strength, hardness, and application. This allows for more precise classification of these iron and steel products based on their specific composition.
