8544.11.00.50 - Other

This classification covers copper winding wire that does not fall into the specific gauge specifications of its sibling categories. Winding wire is typically used to create coils for electrical apparatus such as transformers, motors, generators, and electromagnets. The wire is insulated to prevent short circuits and ensure efficient electrical conductivity within the windings.

The key differentiator for this category lies in the wire gauge. It specifically excludes copper winding wire that is 33 AWG (0.18 mm in diameter) and finer, and also excludes copper winding wire that is 22 AWG (0.643 mm in diameter) and finer but larger than 33 AWG (0.18 mm in diameter). Therefore, this "Other" category captures copper winding wire with gauges falling outside these defined ranges.

As this is a leaf node, there are no further subcategories. Classification under this code relies on confirming the material (copper) and its application as winding wire, while also verifying that its gauge does not align with the more specifically defined sibling categories. Importers should carefully measure the diameter of their copper winding wire to ensure correct classification.
