Carbon brushes; with or without metal, used for electrical purposes

HS v2022 Code: 854520

About carbon brushes; with or without metal, used for electrical purposes

HS code 854520 covers carbon brushes, with or without metal, used for electrical purposes. These brushes are essential components in a wide range of electrical and electronic devices, playing a crucial role in the efficient transfer of electrical current. As a fundamental part of many motors, generators, and other electromechanical systems, the carbon brush industry is integral to the broader electrical and manufacturing sectors, supporting a diverse range of industries and applications.

Production process

The production of carbon brushes typically involves a multi-step process. First, the raw materials, which may include carbon, graphite, and various metal additives, are carefully blended and compacted into the desired brush shape. The brushes are then subjected to high-temperature heat treatment to enhance their durability and conductivity. Finally, the brushes may undergo additional finishing processes, such as grinding or polishing, to ensure precise dimensions and optimal performance.

Production inputs

The main inputs required for the production of carbon brushes include high-quality carbon and graphite materials, as well as various metal additives such as copper, silver, or tin. Specialized machinery, such as compaction presses and heat treatment furnaces, are also essential for the manufacturing process. Additionally, the industry relies on skilled labor to ensure the consistent quality and precision of the final products.

Production outputs

Carbon brushes produced under HS code 854520 are primarily used in a wide range of electrical and electronic devices, including motors, generators, and various types of industrial and consumer equipment. These brushes are often consumed by industries classified under other HS codes, such as 850300 Electric motors and generators, 851140 Ignition magnetos; magneto-dynamos; magnetic flywheels, and 851180 Electrical ignition or starting equipment, among others.
