7228.20 - Bars and rods, of silico-manganese steel:

This HTS category, 7228.20, specifically covers bars and rods manufactured from silico-manganese steel. Silico-manganese steel is an alloy steel characterized by the presence of silicon and manganese, which imparts specific properties such as increased strength and toughness. These products are typically used in applications where high tensile strength and resistance to wear are required.

When classifying within Chapter 72, it is important to distinguish this category from its siblings. For instance, 7228.10 pertains to high-speed steel, a different alloy with distinct properties for cutting tools. Other siblings may cover bars and rods of various alloy steels not further worked than hot-rolled, hot-drawn, extruded, or forged, or those that are cold-formed or cold-finished. Category 7228.20 is specific to the material composition of silico-manganese steel, regardless of its initial working process, as long as it fits the general definition of bars and rods.

Within the 7228.20 category, further distinctions are made based on the forming process. Subcategory 7228.20.10 covers silico-manganese steel bars and rods that have not undergone cold-forming or cold-finishing. Conversely, 7228.20.50 addresses those that have been cold-formed or cold-finished, which typically results in tighter dimensional tolerances and improved surface finish. This differentiation is crucial for accurate customs declarations and duty assessment.
