HS v2017 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, which may or may not be calcined, have a wide range of industrial applications, from construction and ceramics to filtration and absorbents. As a crucial raw material in many manufacturing processes, the global trade and utilization of these clays play a significant role in the broader economy.

Production process

The production of clays classified under HS code 250830 typically involves the extraction of clay deposits from the earth, followed by various processing steps. This may include crushing, screening, washing, and in some cases, calcination (heat treatment) to modify the clay's properties. The specific techniques employed can vary depending on the intended end-use of the clay material.

Production inputs

The primary inputs for the production of clays under HS code 250830 are the raw clay deposits found in the earth's crust. Depending on the desired properties of the final product, additional inputs may include water for washing, energy sources for drying and calcination, and specialized equipment for processing and refining the clay. The availability and quality of these raw clay resources are crucial factors in the industry.

Production outputs

Clays classified under HS code 250830 have a diverse range of applications, serving as essential inputs for various industries. These clays may be used in the production of 6901 Ceramic bricks, blocks, tiles and other ceramic goods, 6903 Other refractory ceramic goods, and 6907 Unglazed ceramic flags and paving, hearth or wall tiles; unglazed ceramic mosaic cubes and the like. Additionally, these clays can be utilized in the manufacture of 3802 Activated carbon; activated natural mineral products; animal black, including spent animal black, 3824 Prepared binders for foundry moulds or cores; chemical products and preparations of the chemical or allied industries, and 6806 Slag wool, rock wool and similar mineral wools; exfoliated vermiculite, expanded clays, foamed slag and similar expanded mineral materials, among other products.
