8539.29.30 - Other

This HTS classification, 8539.29.30, encompasses "Other" filament lamps that are designed for a voltage not exceeding 100 volts, and are not specifically classified under Christmas-tree lamps (8539.29.10) or lamps suitable for surgical instruments with small glass envelopes (8539.29.20). This residual category captures a wide range of general-purpose filament lamps and lighting elements that do not fit into more narrowly defined subheadings within the broader category of other filament lamps.

The key distinguishing factor for items within this classification is their voltage rating, which must be 100 volts or less. It serves as a catch-all for filament lamps that are not ultraviolet or infrared, and are not of the specialized types designated for decorative seasonal lighting or specific medical instruments. The "Other" designation highlights its role in capturing remaining items after more specific filament lamp types have been accounted for.

Within this category, further distinctions are made to refine the classification. The subheading 8539.29.30.20 specifically addresses "Flashlight lamps," indicating that lamps designed for portable battery-operated flashlights are categorized separately. The existence of an "Other" subcategory beneath this level suggests that additional, more granular classifications may exist for other types of filament lamps not covered by flashlight lamps, ensuring precise tariff application based on specific product characteristics.
