HS v2022 Code: 250830

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

HS code 250830 covers a diverse range of clay materials, excluding the expanded clays classified under heading 6806. These clays, including fireclay, are essential raw materials for a variety of industries, from construction and ceramics to refractories and specialized applications. As a key component in many manufacturing processes, the global trade and utilization of these clay products play a significant role in the broader economy.

Production process

The production of clays and fireclay covered under HS code 250830 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 purified to remove impurities, depending on the intended application. For some specialized uses, the clay may undergo further processing, such as calcination or chemical treatment, to enhance its properties and performance.

Production inputs

The primary inputs for the production of clays and fireclay under HS code 250830 are the raw clay deposits themselves. These natural resources are found in various geological formations around the world. In addition to the raw clay, the industry also requires mining and processing equipment, energy sources, and transportation infrastructure to extract, transport, and refine the materials. Depending on the specific application, other inputs such as chemical additives or specialized machinery may also be necessary.

Production outputs

The clays and fireclay classified under HS code 250830 are used as key inputs in a wide range of industries. These materials are commonly used in the production of 6901 Ceramic bricks, blocks, tiles and other ceramic goods, 6902 Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, and 6903 Other refractory ceramic goods. Additionally, they are utilized in the manufacture of 6907 Unglazed ceramic flags and paving, hearth or wall tiles; unglazed ceramic mosaic cubes and the like, 6908 Glazed ceramic flags and paving, hearth or wall tiles; glazed ceramic mosaic cubes and the like, and various other ceramic products.
