7505.21.50.00 - Not cold-formed

This HTS category, 7505.21.50.00, specifically classifies nickel wire that is *not cold-formed*. Cold-forming involves shaping metal at or near room temperature, which typically alters its mechanical properties through work hardening. Therefore, this classification applies to nickel wire that has been processed through methods other than cold deformation, such as hot rolling, extrusion, or drawing followed by annealing. The wire will maintain the intrinsic properties of unalloyed nickel, without the significant structural changes associated with cold working.

Distinguishing this category from its sibling, 7505.21.10.00 (Cold-formed), is crucial. The primary differentiator lies in the manufacturing process. Wire classified under 7505.21.50.00 will not exhibit the characteristic hardness or altered grain structure typically found in cold-formed metals. This distinction is important for assessing potential differences in malleability, tensile strength, and suitability for various applications where the specific mechanical state of the nickel wire is a determining factor.

As this is a leaf node within the HTS, there are no further subcategories. Classification at this level is solely dependent on the material being unalloyed nickel wire and the fact that it has not undergone a cold-forming process. Examples of such wire could include those intended for applications where its inherent ductility and softness, without the effects of cold working, are essential, such as in certain electrical components or specialized welding applications.
