8479.81.00.00 - For treating metal, including electric wire coil-winders

HTS Code 8479.81.00.00 specifically classifies machines and mechanical appliances designed for the treatment of metal that do not fit into more specific headings. A prime example within this subcategory is electric wire coil-winders, which are engineered for the precise winding of wires into coils, a crucial step in the manufacturing of various electrical components. This classification is distinguished from sibling categories by its focus on metal treatment processes that are not encompassed by the mixing, kneading, crushing, grinding, screening, sifting, homogenizing, emulsifying, or stirring actions of 8479.82.00, nor the specialized cold isostatic pressing function of 8479.83.00.00. As this is a leaf node, further subdivisions do not exist, meaning classification here relies on the specific function of metal treatment and the exclusion from more particular machine classifications within Chapter 84.
