8539.31.00.70 - Other

This HTS category, 8539.31.00.70, encompasses fluorescent, hot cathode discharge lamps that do not fall under the specifically defined subcategories of those with a single plug-in base (8539.31.00.50) or a single screw-in base (8539.31.00.60). Essentially, it acts as a residual category for fluorescent lamps requiring a hot cathode ignition method, but lacking the common single-point electrical connection types addressed by its siblings.

The defining characteristic for classification within this "Other" category is the absence of a single plug-in or screw-in base as the primary means of electrical connection. This could include fluorescent lamps with multiple connection points, specialized terminals, or designs that integrate power connection in a manner distinct from standard single-base configurations. When classifying items under this code, it is crucial to confirm that the lamp is indeed a fluorescent, hot cathode type and does not fit the more specific descriptions of its sibling codes.

As this is a leaf node, there are no further subdivisions. Therefore, proper classification hinges on the accurate identification of the lamp's design and its exclusion from the preceding sibling categories. Importers and exporters should carefully examine the electrical connection mechanism of their fluorescent discharge lamps to ensure correct tariff application.
