8533.39.00 - Other

This category, HTS 8533.39, encompasses wirewound variable resistors, including rheostats and potentiometers, that are not designed for a power handling capacity not exceeding 20 W. Unlike the sibling category 8533.31, which specifically covers wirewound variable resistors with a lower power rating, this classification applies to those with a greater power handling capacity. These devices are characterized by their construction utilizing resistance wire wound around a core, allowing for continuous adjustment of resistance by a movable contact.

Within this category, further subdivisions exist to refine classification based on specific applications. The subcategory 8533.39.40 is designated for dimmers, typically used in lighting control systems to adjust the intensity of illumination. The remaining goods that fit the criteria of wirewound variable resistors with a power handling capacity exceeding 20 W, but are not specifically dimmers, fall under the residual subcategory 8533.39.80, designated as "Other."
