7217.10.50.90 - Other

This HTS subcategory, 7217.10.50.90, specifically covers wire of iron or nonalloy steel that is not plated or coated, whether or not polished, contains less than 0.25 percent carbon by weight, has a round cross-section, and possesses a diameter of 1.5 mm or more, but falls outside of any more specific "heat treated" designation. This classification is for finished wire products meeting these precise dimensional and compositional criteria, excluding those that have undergone heat treatment for modified properties.

The distinction from its sibling category, 7217.10.50.30, lies solely in the absence of heat treatment. While both categories share the commonalities of being unplated/uncoated, round, iron or nonalloy steel wire with a carbon content under 0.25% and a diameter of 1.5 mm or greater, the "Other" designation signifies that this wire has not been subjected to any thermal processing intended to alter its microstructure or mechanical properties.

As this is a terminal node within the HTS, there are no further subcategories. Therefore, the classification hinges entirely on the fulfillment of all preceding criteria: being wire of iron or nonalloy steel, not plated or coated, containing less than 0.25 percent carbon by weight, of a round cross-section, with a diameter of 1.5 mm or more, and critically, not having been heat treated. Examples would include bright basic wire or cold drawn wire that meets these specifications and has not undergone any annealing, tempering, or other heat-related processes.
