8539.32.00.20 - Sodium vapor 🖩

This HTS category encompasses sodium vapor discharge lamps. These lamps produce light by passing an electric arc through a gaseous sodium vapor. They are primarily recognized for their characteristic yellow-orange light output and are commonly used for street lighting and industrial applications where efficient, long-lasting illumination is required. The classification hinges on the primary gas medium used within the lamp to produce light.

Distinguishing this category from its siblings is crucial for accurate classification. While this heading covers lamps utilizing sodium vapor, the sibling category 8539.32.00.40 specifically addresses mercury vapor lamps, which rely on mercury vapor to generate their light, typically producing a bluish-white light. The "Other" category, 8539.32.00.90, is reserved for discharge lamps that do not fit the specific descriptions of mercury or sodium vapor lamps.

As this is a leaf node, there are no further subcategories within this specific HTS code. Therefore, classification into 8539.32.00.20 is final once it is determined that the discharge lamp in question operates using sodium vapor as its primary light-producing element. The classification is based on the fundamental technology and primary gas composition of the discharge lamp.
