7217.10.40.45 - Other

This HTS category encompasses wire of iron or nonalloy steel that meets specific physical and compositional criteria. The wire must be neither plated nor coated, though it may have undergone a polishing process. Crucially, it contains less than 0.25 percent by weight of carbon, categorizing it as low-carbon steel. Furthermore, the wire must be round in cross-section and have a diameter measuring less than 1.5 millimeters. The defining characteristic of this particular subcategory is that the wire has undergone a heat treatment process.

This classification is distinguished from its sibling category, 7217.10.40.40, by the packaging or quantity. While both fall under "With a diameter of less than 1.5 mm" and "Heat treated," the sibling specifically covers wire "In coils weighing not more than 2 kilograms." This category, conversely, does not have a weight limitation on the coils, implying a broader range of coil weights is acceptable as long as the other specifications (material, diameter, coating, heat treatment) are met.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the classification is complete at this level based on the specified attributes: the material (iron or nonalloy steel), its state (not plated or coated, whether polished), its carbon content (less than 0.25%), its shape (round wire), its diameter (less than 1.5 mm), and its processing (heat treated). Importers and exporters should ensure all these characteristics precisely match the goods being declared to avoid misclassification.
