HS v2022 Code: 853931

About lamps; discharge, (excluding ultra-violet), fluorescent, hot cathode

HS code 853931 covers a wide range of discharge lamps, excluding ultraviolet and fluorescent types, that utilize a hot cathode design. These lamps are essential components in various industries, from commercial and residential lighting to specialized applications such as stage and studio illumination. Their efficient energy consumption and long lifespan make them a popular choice for a diverse array of lighting needs across the global economy.

Production process

The production of discharge lamps under HS code 853931 typically involves a multi-step process. First, the glass envelope or bulb is formed, often through a molding or blowing process. The electrodes, which are the hot cathodes, are then precisely positioned within the bulb. The bulb is then filled with a specific gas mixture, such as argon or mercury vapor, which is essential for the lamp's discharge mechanism. Finally, the lamp is sealed and any necessary electrical components, such as ballasts or starters, are integrated to ensure proper operation.

Production inputs

The key inputs for the production of discharge lamps under HS code 853931 include high-quality glass for the bulb, specialized electrode materials such as tungsten or molybdenum, and the various gases required for the discharge process. Additionally, manufacturers rely on advanced machinery and equipment, such as vacuum pumps, sealing machines, and automated assembly lines, to ensure consistent quality and efficiency in the production process.

Production outputs

The primary output of the industry covered by HS code 853931 is a diverse range of discharge lamps, including metal halide, high-pressure sodium, and other specialized types. These lamps are widely used in 853910 Lamps; electric filament or discharge lamps, sealed beam lamp units and 853921 Lamps; fluorescent, hot cathode, as well as in various other lighting applications across the commercial, industrial, and residential sectors.
