Kaolin and other kaolinic clays; whether or not calcined

HS v2022 Code: 2507

About kaolin and other kaolinic clays; whether or not calcined

HS code 2507 covers kaolin and other kaolinic clays, which are essential raw materials in a wide range of industries. Kaolin is a fine, white clay mineral that is valued for its chemical stability, brightness, and ability to impart specific properties to various products. This industry plays a crucial role in the manufacturing of ceramics, paper, paints, plastics, and many other important goods, making it a vital component of the global economy.

Production process

The production of kaolin and other kaolinic clays typically involves mining, processing, and refining. The raw clay is extracted from deposits, then crushed, dried, and purified to remove impurities. Depending on the intended use, the clay may undergo further processing, such as calcination (heating to high temperatures), to modify its physical and chemical properties.

Production inputs

The main inputs for the kaolin and kaolinic clay industry include the raw clay deposits, which are typically found in sedimentary rock formations. Additionally, the industry relies on specialized mining and processing equipment, as well as energy sources, such as electricity or fuel, to power the various stages of production. Transportation infrastructure is also a key input, as the processed clay must be delivered to manufacturers and other end-users.

Production outputs

The primary outputs of the kaolin and kaolinic clay industry are the refined and processed clay products, which are then used as inputs in a wide range of other industries. These include the 2008 Ceramics, 4802 Paper, 3207 Paints and coatings, and 3904 Plastics industries, among others. The specific properties and characteristics of the kaolin and kaolinic clays determine their suitability for different applications.
