7226.11.90 - Of a width of less than 300 mm

This HTS category, 7226.11.90, specifically covers grain-oriented flat-rolled products of other alloy steel that are less than 300 mm in width. These materials are crucial components in the manufacturing of electrical transformers and other electromagnetic devices, where their specific magnetic properties, achieved through controlled grain orientation, are essential for efficient energy conversion. The key defining characteristic here is the narrow width, distinguishing them from wider products within the same broader classification.

This classification differs from its sibling, 7226.11.10.00, primarily in the specified width. While both fall under grain-oriented silicon electrical steel, 7226.11.10.00 encompasses products with a width of 300 mm or more. Therefore, the width of the flat-rolled product is the definitive criterion for differentiating between these two sibling HTS codes.

Within this category, further subdivisions exist to refine classification based on thickness. The subcategories, 7226.11.90.30 and 7226.11.90.60, allow for more precise categorization based on whether the material's thickness does not exceed 0.25 mm, or if it falls into any other thickness range not otherwise specified. This detailed breakdown ensures that the exact specifications of the imported or exported material are accurately reflected in the customs declaration.
