7228.50 - Other bars and rods, not further worked than cold-formed or cold-finished:

HTS 7228.50 encompasses "Other bars and rods, not further worked than cold-formed or cold-finished," specifically within the broader category of bars and rods made from materials other than high-speed steel or silico-manganese steel. This classification applies to iron and steel products that have undergone cold working processes, such as cold drawing, cold rolling, or cold heading, which alter their shape or dimensions without significant heat treatment. These cold-forming or cold-finishing operations typically result in improved surface finish, dimensional accuracy, and increased strength compared to hot-worked products.

This category is distinguished from its siblings by the *method of working* applied. While other sibling categories might cover bars and rods that are hot-rolled, hot-drawn, extruded, or forged (7228.30 and 7228.40 respectively), 7228.50 specifically excludes these processes, focusing exclusively on cold-formed or cold-finished items. It also differentiates from high-speed steel (7228.10) and silico-manganese steel (7228.20) by the specific alloy composition of the steel.

Subdivision within 7228.50 is based on the type of steel. The subcategory 7228.50.10 is reserved for cold-formed or cold-finished bars and rods of tool steel, excluding high-speed steel. The broader subcategory 7228.50.50 captures all other remaining bars and rods that meet the criteria of being not further worked than cold-formed or cold-finished, encompassing a wide range of alloy and non-alloy steels not specifically designated elsewhere.
