8539.39 - Other:

HTS code 8539.39 encompasses discharge lamps that are not classified under the more specific categories of fluorescent, hot cathode lamps (8539.31), nor mercury, sodium vapor, or metal halide lamps (8539.32). This residual category serves as a catch-all for discharge lamp types that do not fit the preceding descriptions. It is crucial to identify the specific discharge mechanism and intended application to correctly classify goods within this heading, as it includes a diverse range of lighting technologies.

Unlike its siblings, 8539.31 focuses exclusively on fluorescent lamps requiring a heated cathode for operation, while 8539.32 details specific types of vapor discharge lamps. Therefore, 8539.39 is reserved for discharge lamps that operate on different principles or are designed for distinct purposes not covered by these more narrowly defined categories. This distinction is vital for accurate tariff application, ensuring that all types of discharge lamps are accounted for within Chapter 85.

Within the 8539.39 classification, two principal subcategories exist. Code 8539.39.10.00 specifically addresses cold-cathode fluorescent lamps (CCFLs) that are exclusively used for the backlighting of flat panel displays. The remaining discharge lamps that do not fall into the CCFL category or the previously mentioned sibling categories are consolidated under 8539.39.90.00, designated as "Other." This subdivision allows for the precise classification of less common or specialized discharge lighting technologies.
