7211.23.45.00 - Of a thickness not exceeding 0.25 mm

This HTS category, 7211.23.45.00, specifically covers flat-rolled products of iron or non-alloy steel that are less than 600 mm in width, not clad, plated, or coated, and have undergone cold-rolling (cold-reduction). The defining characteristic of this subcategory is its precise thickness: not exceeding 0.25 mm. These are very thin steel products, often used in applications where extreme thinness is critical for functionality or material efficiency.

This classification is distinct from its siblings primarily based on thickness. For example, it differs from 7211.23.30.00, which covers products with a greater thickness, specifically exceeding 0.25 mm but not exceeding 1.25 mm. Furthermore, it is differentiated from the sibling category of "Of a thickness exceeding 1.25 mm" by this same critical dimensional parameter. The material composition, as indicated by the parent category, requires a low carbon content of less than 0.25% by weight, and the width must be less than 300 mm.

As this node represents a leaf node within the HTS, there are no further subcategories. Therefore, the classification is determined entirely by the specific combination of physical characteristics already defined: cold-rolled, iron or non-alloy steel, width less than 600 mm, not clad, plated or coated, width less than 300 mm, containing less than 0.25% carbon by weight, and a thickness not exceeding 0.25 mm. Examples of such products might include foils used in electronics, certain types of packaging, or components in precision instruments where extreme thinness is essential.
