7211.23.60.90 - Of a thickness not exceeding 0.25 mm: 🖩

This HTS category, 7211.23.60.90, specifically covers flat-rolled products of iron or nonalloy steel that have been cold-rolled (cold-reduced) and contain less than 0.25 percent carbon by weight. Crucially, these products are characterized by their exceptionally thin gauge, having a thickness **not exceeding 0.25 mm**. These are typically supplied in coils or cut lengths and are not further worked beyond the cold-rolling process, meaning they haven't undergone additional treatments like cladding, plating, or coating.

The defining characteristic of this category, differentiating it from its siblings, is its specific thickness requirement. While 7211.23.60.30 covers thicker materials (exceeding 1.25 mm) and 7211.23.60.60 addresses an intermediate range (exceeding 0.25 mm but not exceeding 1.25 mm), this classification is exclusively for the thinnest of these cold-rolled flat products, those **not exceeding 0.25 mm** in thickness. This precise measurement is a critical factor for correct customs classification.

As a leaf node within the HTS, category 7211.23.60.90 represents the most granular level of classification for this specific type of steel product. Therefore, there are no further subcategories to introduce. Classification into this code is final based on the product meeting all the preceding criteria: being flat-rolled iron or nonalloy steel, of a width less than 600 mm, not clad, plated, or coated, cold-rolled, containing less than 0.25 percent carbon, and having a thickness not exceeding 0.25 mm. Examples of such items would include certain types of very thin steel shim stock or components for electronic devices.
