7225.11.00.00 - Grain-oriented

This HTS classification, 7225.11.00.00, specifically covers grain-oriented flat-rolled products of other alloy steel, with a width of 600 mm or more. These products are distinguished by their unique magnetic properties, achieved through a specific manufacturing process that aligns the crystal grain structure in a particular direction. This grain orientation is crucial for their primary application in electrical equipment, such as transformers, where it significantly reduces energy losses.

This category is distinct from its sibling, 7225.19.00.00, which encompasses "other" silicon electrical steel. While both fall under the broader heading of flat-rolled products of other alloy steel, 7225.11.00.00 exclusively identifies the *grain-oriented* varieties. The defining characteristic here is the engineered magnetic anisotropy, meaning the material exhibits different magnetic properties depending on the direction of magnetization relative to the rolling direction. Products classified under 7225.19.00.00, on the other hand, would include silicon electrical steel that is not grain-oriented, such as non-oriented or random-oriented types.

As this node represents a leaf category within the HTS, there are no further subcategories. The classification is specific to the described characteristics of grain-oriented silicon electrical steel. Practical classification will rely on verifying the material composition (alloy steel with silicon) and the characteristic grain-oriented structure, often confirmed through technical specifications or material certificates, in addition to the width requirement of 600 mm or more.
