Clays (excluding expanded clays of heading no. 6806); andalusite, kyanite and sillimanite, whether or not calcined

HS v2017 Code: 250850

About clays (excluding expanded clays of heading no. 6806); andalusite, kyanite and sillimanite, whether or not calcined

HS code 250850 covers a diverse range of non-metallic mineral products, including various types of clay, andalusite, kyanite, and sillimanite. These materials have a wide range of industrial applications, from ceramics and refractories to fillers and absorbents. The global trade in these commodities is significant, with developing economies often serving as major producers and exporters to meet the demands of industrialized nations.

Production process

The production of the materials covered under HS code 250850 typically involves mining, processing, and refining. Clay deposits are extracted from the earth, often through open-pit or underground mining techniques. The raw clay is then crushed, dried, and sometimes calcined (heat-treated) to modify its properties. Andalusite, kyanite, and sillimanite are also mined and may undergo similar processing steps, depending on the intended use.

Production inputs

The primary inputs for the production of HS code 250850 materials are the natural mineral deposits themselves. Mining equipment, such as excavators, crushers, and drying facilities, are also essential. Depending on the specific application, additional inputs may include energy sources (e.g., electricity, fuel) for processing, as well as water for washing and beneficiation. Transportation infrastructure, such as roads and railways, is crucial for the movement of raw materials and finished products.

Production outputs

The materials covered under HS code 250850 have a wide range of industrial applications. Clays are used in the production of 691010 ceramic sanitary fixtures, 690210 refractory bricks, blocks, tiles, and similar refractory ceramic constructional goods, and as fillers and absorbents in various industries. Andalusite, kyanite, and sillimanite are primarily used in the manufacture of 690310 refractory ceramic goods, such as furnace linings and crucibles. These materials may also be consumed by other industries, such as 680620 mineral wools and similar mineral insulations.
