Chapter 85 covers electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles. This chapter includes equipment for generating, transforming, storing, and using electricity, as well as lighting devices, but excludes mechanical products such as steam boilers and internal combustion engines. Sodium vapor lamps, as electric light source products, fall within the scope of electrical lighting equipment and are therefore classified in this chapter. Heading 8539 covers various electric filament or discharge lamps, including incandescent lamps, discharge tubes (such as fluorescent lamps, sodium vapor lamps, mercury vapor lamps, etc.), arc lamps, and light-emitting diode (LED) lamps. This heading also includes sealed beam lamp units, ultraviolet lamps, and infrared lamps. However, it excludes unfinished articles with glass envelopes not fitted with filaments or discharge electrodes, as well as luminaires and lighting fittings (heading 9405). Code 853963 is a six-digit subheading. The first two digits 85 indicate Chapter 85 (electrical machinery and equipment and parts thereof). Digits 3-4, 39, indicate heading 8539 (electric filament or discharge lamps). Digits 5-6, 63, indicate subheading 8539.63, namely sodium vapor lamps. In the HS classification, heading 8539 is subdivided by lamp type: 8539.10 for sealed beam lamp units, 8539.21 for fluorescent lamps, 8539.22 for other mercury vapor lamps, 8539.29 for other discharge lamps, 8539.31 for hot cathode fluorescent lamps, 8539.32 for mercury vapor lamps, 8539.39 for other, 8539.41 for arc lamps, 8539.49 for ultraviolet or infrared lamps, 8539.51 for light-emitting diode (LED) lamps, 8539.52 for other LED lamps, and 8539.90 for parts. 8539.63 specifically refers to sodium vapor lamps, which are a type of discharge lamp. Sodium vapor lamps emit light through sodium vapor discharge and belong to discharge lamps. Their core characteristic is sodium vapor as the luminescent substance, so they are classified under 8539.63. If they were mercury vapor lamps, they would be classified under 8539.32; if they were other discharge lamps, they would be classified under 8539.39. They differ from incandescent lamps (8539.10 or 8539.21, etc.) in that the light-emitting principle is different. They differ from LED lamps (8539.51/52) in the type of light source.

🎯 Classification Logic
The core basis for classification is the Import and Export Tariff and the Harmonized Commodity Description and Coding System. Sodium vapor lamps belong to discharge lamps, and their light-emitting principle is sodium vapor discharge, which conforms to the description of heading 8539. According to the subheading structure, 8539.63 explicitly lists "sodium vapor lamps", so they should be classified under this subheading. If they were mercury vapor lamps, they would be classified under 8539.32; if they were other discharge lamps, they would be classified under 8539.39. At the same time, note that if the lamp is of the LED type, even if the name contains "sodium", it should be classified under 8539.51/52. 853932 Mercury vapor lamps: Mercury vapor lamps emit light through mercury vapor discharge, while sodium vapor lamps use sodium vapor discharge; the luminescent substances are different, so the subheadings differ. 853939 Other discharge lamps: This subheading covers other discharge lamps besides those specifically named, such as fluorescent lamps, mercury vapor lamps, sodium vapor lamps, etc., such as metal halide lamps. Sodium vapor lamps already have a specific subheading and should not be classified here. 853951 Light-emitting diode (LED) lamps: LED lamps are based on semiconductor light emission, which is completely different from the gas discharge principle of sodium vapor lamps, so the classification is different. 940540 Other electric lighting fittings: 9405 covers luminaires and lighting fittings. If sodium vapor lamps have been assembled into luminaires, they should be classified under 9405 rather than 8539. Confirm whether the light-emitting principle is sodium vapor discharge. Confirm whether it is a high-pressure or low-pressure sodium lamp. Confirm whether it has been assembled into a luminaire (if assembled, classify under 9405). Confirm whether it has complete lamp characteristics such as a lamp base and lamp holder. Confirm whether it is of the LED type (if so, classify under 8539.51/52).

Confused Codes：
853932 - Mercury vapor lamps
Mercury vapor lamps emit light through mercury vapor discharge, while sodium vapor lamps use sodium vapor discharge; the luminescent substances are different, so the subheadings differ.
853939 - Other discharge lamps
This subheading covers other discharge lamps besides those specifically named, such as fluorescent lamps, mercury vapor lamps, sodium vapor lamps, etc., such as metal halide lamps. Sodium vapor lamps already have a specific subheading and should not be classified here.
853951 - Light-emitting diode (LED) lamps
LED lamps are based on semiconductor light emission, which is completely different from the gas discharge principle of sodium vapor lamps, so the classification is different.
940540 - Other electric lighting fittings
9405 covers luminaires and lighting fittings. If sodium vapor lamps have been assembled into luminaires, they should be classified under 9405 rather than 8539.
Self-Check：
✓ Confirm whether the light-emitting principle is sodium vapor discharge.
✓ Confirm whether it is a high-pressure or low-pressure sodium lamp.
✓ Confirm whether it has been assembled into a luminaire (if assembled, classify under 9405).
✓ Confirm whether it has complete lamp characteristics such as a lamp base and lamp holder.
✓ Confirm whether it is of the LED type (if so, classify under 8539.51/52).
❓ FAQ
What is the difference in HS codes between sodium vapor lamps and metal halide lamps? Sodium vapor lamps are classified under 8539.63, while metal halide lamps belong to other discharge lamps and are classified under 8539.39. The luminescent substances are different, and classification should be determined based on the actual product. How can one determine whether a lamp is a high-pressure sodium lamp or a low-pressure sodium lamp? High-pressure sodium lamps are usually smaller, have high luminous efficacy and long life, and emit golden-white light; low-pressure sodium lamps are larger and emit monochromatic yellow light. At declaration, they should be distinguished based on product technical parameters, but both have the same HS code. In the declaration elements for sodium vapor lamps, is power mandatory? Yes, power is an important declaration element, and customs may judge product characteristics based on power. Omitting it may lead to inaccurate declaration, so it is recommended to fill it in completely. If a sodium vapor lamp comes with a ballast, how should it be classified? If the lamp and ballast are packaged separately, classify them separately: the lamp under 8539.63 and the ballast under 8504. If they have been assembled into an integrated luminaire, classify under 9405. What are the export regulatory conditions for sodium vapor lamps? Export regulatory conditions should be checked according to customs regulations and usually involve commodity inspection, certification, etc. It is recommended to consult the latest Export Tariff or consult the local customs. When selling sodium vapor lamps on cross-border e-commerce platforms, how should the HS code be filled in? Cross-border e-commerce sellers should truthfully fill in HS code 853963 and ensure that the declaration elements are complete. If the platform requires it, refer to the customs declaration form filling specifications. How can the import tariff rate for sodium vapor lamps be checked? Tariff rates change. The latest rates can be checked through the General Administration of Customs website, China International Trade Single Window, or the Import and Export Tariff. Different rules of origin may apply different agreement rates. If a sodium vapor lamp is used for special equipment, is the classification different? If the lamp is a part of special equipment and that equipment has an independent heading, it may be classified as a part of the equipment. However, sodium vapor lamps for general lighting are still classified under 8539.63.
