HS v2022 Code: 853921

About lamps; filament, (excluding ultra-violet or infra-red), tungsten halogen

HS code 853921 covers the import and export of tungsten halogen filament lamps, which are a type of incandescent light bulb. These lamps are widely used in a variety of applications, including residential, commercial, and industrial lighting. They are known for their energy efficiency, long lifespan, and ability to produce a bright, focused light. The tungsten halogen lamp industry plays a significant role in the broader lighting and electrical equipment sector, contributing to the overall illumination needs of the global economy.

Production process

The production of tungsten halogen filament lamps involves several key steps. First, the tungsten filament is carefully shaped and positioned within a glass or quartz envelope. This envelope is then filled with a small amount of halogen gas, such as iodine or bromine. During operation, the halogen gas interacts with the tungsten filament, creating a cycle that redeposits evaporated tungsten back onto the filament, extending its lifespan. The lamp is then sealed and tested for quality before being packaged and distributed.

Production inputs

The main inputs required for the production of tungsten halogen filament lamps include high-purity tungsten wire, quartz or glass envelopes, halogen gas, and various electrical components such as sockets and connectors. Specialized machinery and equipment, such as filament winding machines and vacuum sealing systems, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in lamp design, assembly, and quality control.

Production outputs

The primary output of the tungsten halogen filament lamp industry is, of course, the lamps themselves. These lamps are widely used in a variety of applications, including 853910 Lamps; electric filament or discharge lamps, including sealed beam lamp units and ultraviolet or infra-red lamps, 853921 (Lamps; filament, (excluding ultra-violet or infra-red), tungsten halogen), and 853929 Lamps; electric filament or discharge lamps, n.e.c. in heading no. 8539. The industry's output also supports the broader lighting and electrical equipment sectors, providing essential illumination solutions for residential, commercial, and industrial settings.
