7227.20.00 - Of silico-manganese steel

This HTS category, 7227.20.00, specifically classifies bars and rods of silico-manganese steel that are hot-rolled and presented in irregularly wound coils. Silico-manganese steel is an alloy steel characterized by its silicon and manganese content, which imparts specific properties such as increased hardness, strength, and elasticity, making it suitable for various industrial applications.

Distinguishing this category from its siblings, 7227.10.00.00 covers high-speed steel coils, which are designed for cutting tools due to their ability to maintain hardness at elevated temperatures. Category 7227.90 encompasses "other" alloy steels not otherwise specified within the 7227 heading. Therefore, 7227.20.00 is uniquely defined by its specific alloy composition of silico-manganese steel.

Within this category, two subcategories exist to further refine the classification. 7227.20.00.30 applies to silico-manganese steel wire rods specifically intended for welding, as outlined in the relevant statistical note. The remaining silico-manganese steel coils fall under the general "Other" designation at 7227.20.00.80, covering all other uses and product types not meeting the specific welding quality criteria.
