HS Code for Sodium vapor lamp

Sodium vapor lamps are classified under HS code 8539.32. This classification is determined by the technical nature of the product as an electric discharge lamp. Unlike filament lamps that produce light through the heating of a wire, discharge lamps generate illumination by passing an electric current through a gas or vapor—in this case, sodium. Under the Harmonized System, heading 8539 covers all types of electric filament or discharge lamps, including sealed beam lamp units and ultra-violet or infra-red lamps. Subheading 8539.32 is specifically reserved for mercury or sodium vapor lamps and metal halide lamps. The classification remains consistent regardless of whether the lamp is high-pressure (HPS) or low-pressure (LPS), provided it functions via the excitation of sodium vapor. These lamps are widely used in industrial settings, street lighting, and horticulture due to their high luminous efficacy. The classification process follows General Interpretative Rule (GRI) 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Since 8539.32 explicitly mentions sodium vapor lamps, it is the primary code for these products.

Products Included

Common Misclassification

A frequent error involves classifying sodium vapor lamps under HS code 8539.21, which is reserved for tungsten halogen filament lamps. While both are used in high-intensity applications, the physical mechanism of light production is fundamentally different. Another common mistake is using 8539.52 for LED lamps, which are increasingly replacing discharge lamps but fall under a separate technological category. Furthermore, if the lamp is part of a complete luminaire (the fixture itself), it should be classified under heading 9405 rather than 8539. Understanding the distinction between the bulb (the lamp) and the fixture (the luminaire) is essential for correct classification.

FAQ

What is the HS code for sodium vapor lamp?

The correct HS code is 8539.32, which specifically covers discharge lamps including mercury or sodium vapor lamps and metal halide lamps.

Are ballast units included in this HS code?

No, electrical ballasts used to regulate the current in discharge lamps are classified separately under HS code 8504.10. If the lamp and ballast are integrated into a fixture, the assembly is classified under 9405.
