8544.19.00.00 - Other

This HTS category, 8544.19.00.00, specifically covers winding wire that is insulated and is not made of copper. Winding wire is typically used in the construction of electrical devices such as motors, transformers, solenoids, and other electromagnetic equipment. Its primary function is to create coils that generate or respond to magnetic fields. The insulation is crucial for preventing short circuits and ensuring the safe and efficient operation of these electrical components.

The distinction from its sibling category, 8544.11.00 (Winding wire of copper), is solely based on the material composition of the conductor. While 8544.11.00 exclusively enumerates winding wire where the conductive element is copper, this category encompasses winding wire where the conductive element is made from any other material. This includes, but is not limited to, aluminum or silver winding wires.

As this is a leaf node in the HTS classification, there are no further subcategories under 8544.19.00.00. Therefore, the classification of goods within this heading will be determined by their characteristic as insulated winding wire of a material other than copper, intended for use in electrical apparatus. The specific type of insulation (e.g., enamel, varnish, or other polymers) and its physical form (e.g., round, square, or rectangular cross-section) are important factors in confirming its placement within this designation.
