Clays (excluding expanded clays of heading no. 6806); mullite

HS v2022 Code: 250860

About clays (excluding expanded clays of heading no. 6806); mullite

HS code 250860 covers a diverse range of natural clay minerals, excluding the expanded clays classified under heading 6806. These clays are widely used in various industries, from ceramics and construction materials to filtration and absorbents. As a crucial raw material, the global clay industry plays a significant role in supporting a wide array of manufacturing and processing activities across numerous economic sectors.

Production process

The production of clays classified under HS code 250860 typically involves the extraction of naturally occurring clay deposits, followed by processing steps such as crushing, screening, and purification. Depending on the specific application, the clays may undergo further refinement, such as beneficiation or chemical treatment, to enhance their physical and chemical properties.

Production inputs

The primary inputs for the clay industry under HS code 250860 are the natural clay deposits found in various geological formations. In addition to the raw clay material, the production process may require specialized mining and processing equipment, as well as energy sources, water, and other ancillary materials. The availability and quality of the clay reserves, as well as the accessibility of these resources, are critical factors in the industry's operations.

Production outputs

The clays classified under HS code 250860 are versatile materials with a wide range of applications. They are commonly used in the manufacture of 691010 ceramic sanitary fixtures, 690210 refractory bricks, blocks, tiles, and similar refractory ceramic constructional goods, and 690410 building bricks. Additionally, these clays may be utilized in the production of 340220 surface-active preparations, 380210 activated carbon, and 380830 herbicides, anti-sprouting products, and plant-growth regulators.
