Clays (excluding expanded clays of heading no. 6806); chamotte or dinas earths

HS v2017 Code: 250870

About clays (excluding expanded clays of heading no. 6806); chamotte or dinas earths

HS code 250870 covers a diverse range of clay materials, excluding the expanded clays classified under heading 6806. These clays, along with chamotte and dinas earths, are essential raw materials for various industries, including ceramics, construction, and specialized applications. Their unique physical and chemical properties make them indispensable in the production of a wide array of products, contributing significantly to the global economy.

Production process

The production of clays and related materials under HS code 250870 typically involves extraction, processing, and refinement. Clay deposits are mined from the earth, and the raw material is then subjected to various processing steps, such as crushing, screening, and purification, to remove impurities and achieve the desired properties. Depending on the specific application, the clays may undergo further treatments, such as calcination or blending, to enhance their performance characteristics.

Production inputs

The key inputs for the industries covered by HS code 250870 include the raw clay deposits, which are the primary source material. Additionally, these industries may require specialized equipment and machinery for extraction, processing, and transportation. Energy sources, such as electricity or fuel, are also essential for the various production stages. Depending on the specific application, other additives or materials may be required to modify the properties of the clay-based products.

Production outputs

The industries under HS code 250870 produce a wide range of clay-based materials, including various types of clays, chamotte, and dinas earths. These outputs are then consumed by a diverse set of downstream industries, such as 6901 Bricks, blocks, tiles and other ceramic goods, 6902 Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, and 6903 Other refractory ceramic goods. The clay-based materials are also used in the production 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 a variety of other ceramic products.
