8539.29 - Other:

HTS code 8539.29 encompasses "Other" filament lamps, specifically those that are not tungsten halogen types (8539.21) and are not of the "other" subcategory for power not exceeding 200 W and voltage exceeding 100 V (8539.22). This category therefore includes filament lamps that fall outside the more specific descriptions of its sibling categories, typically characterized by their filament-based illumination technology.

The key differentiator for this category lies in the exclusion of specific technical attributes already defined in the sibling nodes. While 8539.21 is exclusively for tungsten halogen lamps, and 8539.22 targets a specific range of power and voltage, 8539.29 captures all remaining filament lamps not meeting those precise criteria. This means the classification hinges on the absence of tungsten halogen elements and/or being outside the specified 200W/100V parameters of its immediate sibling.

Within 8539.29, further subdivisions exist based on the operational voltage of the lamp. Subcategories differentiate between lamps "Designed for a voltage not exceeding 100 V" and those "Designed for a voltage exceeding 100 V," as represented by HTS code 8539.29.40.00. This distinction is crucial for customs purposes, as voltage ratings can impact product standards, safety regulations, and market eligibility for imported goods.
