7228.20.50.00 - Cold-formed

This HTS classification, 7228.20.50.00, specifically covers bars and rods manufactured from silico-manganese steel that have undergone a cold-forming process. Silico-manganese steel is an alloy steel characterized by its high manganese and silicon content, which imparts enhanced strength, toughness, and fatigue resistance. The cold-forming process, which involves shaping the steel at or near room temperature, results in improved dimensional accuracy, surface finish, and mechanical properties compared to hot-formed steel.

This category is distinguished from its sibling, 7228.20.10.00, by the method of processing. While both cover bars and rods of silico-manganese steel, 7228.20.10.00 pertains to those that have *not* been cold-formed, meaning they were likely shaped through hot rolling or extrusion. The crucial differentiating factor for 7228.20.50.00 is the application of cold working techniques, such as cold drawing or cold rolling, to achieve the final shape and characteristics of the bars and rods.

As a leaf node within the HTS structure, this category does not have further subcategories. Therefore, classification within 7228.20.50.00 relies on confirming that the item is indeed a bar or rod made of silico-manganese steel and that it has been subjected to cold-forming processes. Examples of such products could include precision ground bars for high-stress automotive components or cold-drawn rods used in specialized tooling where tight tolerances and superior surface quality are essential.
