Mica, including splittings; mica waste

HS v2017 Code: 2525

About mica, including splittings; mica waste

HS code 2525 covers the trade and production of mica, a naturally occurring mineral that has a wide range of industrial applications. Mica is valued for its unique physical properties, including its electrical insulation, heat resistance, and flexibility. The mica industry plays a crucial role in various sectors, such as electronics, construction, and automotive, making it an important component of the broader global economy.

Production process

Mica is primarily extracted from mica-bearing rocks through mining operations. The extracted mica is then processed through a series of steps, including sorting, cleaning, and size grading. Depending on the specific application, mica may be further processed into thin sheets, flakes, or powders. Advanced techniques, such as mechanical splitting and chemical treatment, are often employed to refine the mica and enhance its properties.

Production inputs

The mica industry relies on several key inputs, including the raw mica ore, which is the primary raw material. Additionally, the industry requires specialized mining and processing equipment, as well as energy sources, such as electricity and fuel, to power the production facilities. Transportation infrastructure is also crucial for the movement of mica products to domestic and international markets.

Production outputs

The mica produced under HS code 2525 is used in a wide range of applications, including 8541 (Diodes, transistors and similar semiconductor devices; photosensitive semiconductor devices, including photovoltaic cells whether or not assembled in modules or made up into panels; light-emitting diodes (LED); mounted piezo-electric crystals), 8542 Electronic integrated circuits, 6810 Articles of cement, of concrete or of artificial stone, whether or not reinforced, and 8708 Parts and accessories of the motor vehicles of headings 8701 to 8705. The versatility of mica makes it an essential component in many industries, contributing to the overall growth and development of the global economy.
