HS v2017 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 an essential component in a wide range of electrical equipment, including motors, generators, and various industrial and consumer appliances. As a critical interface between stationary and rotating parts, carbon brushes play a vital role in the efficient and reliable operation of many electrical systems across diverse industries.

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 selected and blended. The mixture is then compressed into the desired brush shape using specialized machinery. Finally, the brushes may undergo additional processing, such as heat treatment or surface finishing, to enhance their performance and durability.

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 other conductive elements. Specialized machinery, such as compaction presses and heat treatment equipment, are also essential for the manufacturing process. Additionally, skilled labor and technical expertise are necessary to ensure the consistent production of high-quality carbon brushes.

Production outputs

Carbon brushes produced under hs code 854520 are primarily used in a wide range of electrical equipment, including 850300 Electric motors and generators, 851140 Electrical transformers, and 851680 Electrical machines and apparatus.
