7217.10.40.90 - Other

This HTS category, 7217.10.40.90, specifically covers "Other" wire of iron or nonalloy steel that meets precise specifications. These wires are not plated or coated, and are considered "polished" if any surface finishing has been applied. Crucially, they contain less than 0.25 percent by weight of carbon and are of a round cross-section with a diameter measuring less than 1.5 mm. This granular detail ensures that only wires fitting these exact physical and compositional parameters fall under this classification.

It is important to distinguish this category from its siblings. The primary differentiating factor is the absence of heat treatment. While other wires at this level might undergo annealing or other thermal processes to alter their properties, the wire classified here is not subjected to such treatments. This means its inherent mechanical properties, as determined by its composition and manufacturing process (excluding heat treatment), are the key defining characteristics for classification.

As this is a leaf node, there are no further subcategories within this specific HTS code. Therefore, classification is complete at this level, focusing solely on the defined characteristics: wire of iron or nonalloy steel, not plated or coated, less than 0.25% carbon, round, and with a diameter under 1.5 mm, excluding any heat-treated variants. This ensures precise and consistent application for import and export purposes.
