Clays (excluding expanded clays of heading no. 6806); bentonite, whether or not calcined

HS v2017 Code: 250810

About clays (excluding expanded clays of heading no. 6806); bentonite, whether or not calcined

HS code 250810 covers a diverse range of clay minerals, including the important industrial mineral bentonite. These natural clay materials are widely used across various industries, from construction and manufacturing to agriculture and environmental applications. As a key raw material, the production and trade of these clays play a significant role in the global economy, supporting a wide range of downstream activities and products.

Production process

The production of clays and bentonite typically involves mining and processing the naturally occurring mineral deposits. This may include extraction, crushing, screening, and sometimes calcination or other treatment processes to refine the clay and enhance its properties for specific applications. The exact techniques can vary depending on the type of clay, its intended use, and the local geological conditions.

Production inputs

The primary inputs for the clay and bentonite industry are the natural mineral deposits found in the earth's crust. Depending on the specific application, other inputs may include energy sources for processing, water for beneficiation, and machinery for mining, crushing, and transportation. The availability and quality of the raw clay materials are crucial factors in determining the industry's productivity and competitiveness.

Production outputs

The clays and bentonite produced under HS code 250810 have a wide range of applications. They are used as fillers, absorbents, and additives in industries such as 252010 Cement, 681011 Building blocks and bricks, 340220 Cleaning preparations, and 310520 Mineral or chemical fertilizers. The outputs of this industry can also be further processed and traded under other HS codes, such as 680620 Exfoliated vermiculite, expanded clays, foamed slag and similar expanded mineral materials.
