7217.10.10.00 - Of a thickness not exceeding 0.25 mm

This HTS category, 7217.10.10.00, specifically classifies iron or non-alloy steel wire that is not plated or coated, whether or not it has been polished. A key defining characteristic of the wire within this classification is its physical dimension: it must have a thickness that does not exceed 0.25 mm. This precise measurement criterion is crucial for distinguishing it from other flat wire products under heading 7217.10.

To further clarify its placement, this category can be distinguished from its siblings based on thickness. HTS codes 7217.10.20.00 and 7217.10.30.00 cover flat wire with greater thicknesses, specifically exceeding 0.25 mm but not exceeding 1.25 mm, and exceeding 1.25 mm, respectively. Therefore, the primary differentiator between these sibling categories is the precise measurement of the wire's thickness, with 7217.10.10.00 being reserved for the thinnest flat wire.

As a leaf node, this category does not have further subcategories. This means that once a product meets the criteria of being unplated/uncoated, flat wire of iron or non-alloy steel with a thickness not exceeding 0.25 mm, it is definitively classified under this HTS code. Examples of such wire might include extremely fine wires used in precision manufacturing, certain types of filament, or specialized weaving applications where thinness is paramount.
