7216.91.00 - Cold-formed or cold-finished from flat-rolled products

This HTS category, 7216.91.00, specifically addresses angles, shapes, and sections manufactured from iron or non-alloy steel that have undergone cold-forming or cold-finishing processes applied to flat-rolled products. This implies that the initial material was in the form of sheets or coils and was subsequently shaped without heating, resulting in tighter tolerances and improved surface finishes compared to hot-rolled alternatives. The "Other" designation at this level indicates it captures products within this cold-formed category that do not fit into more specific sub-classifications.

Within the broader heading of "Angles, shapes and sections of iron or nonalloy steel," this sub-category, 7216.91, is distinguished from its sibling 7216.99 ("Other") by the specific manufacturing process. While 7216.99 would cover any other angles, shapes, or sections not otherwise specified, 7216.91 is exclusively for those derived from flat-rolled products via cold-forming or cold-finishing. This distinction is crucial for accurate tariff application based on the precise method of production and the initial form of the base metal.

The subcategories under 7216.91.00 provide further specificity based on post-forming modifications. Subcategory 7216.91.00.10 covers items that have undergone additional processing such as drilling, notching, punching, or cambering, indicating a more finished product ready for assembly or specific structural applications. The residual subcategory, 7216.91.00.90, acts as a catch-all for cold-formed or cold-finished sections derived from flat-rolled products that have not undergone these specific secondary operations.
