About salt; sulphur; earths, stone; plastering materials, lime and cement

HS code 25 encompasses a diverse range of mineral-based products that are essential for various industries and construction activities. This sector plays a crucial role in the global economy, providing raw materials for a wide array of applications, from building construction to chemical manufacturing. The products under this code are fundamental to the development and infrastructure of both developed and developing nations, making it a significant contributor to economic growth and progress.

Production process

The production techniques for the industries covered under HS code 25 vary depending on the specific product. Generally, the extraction and processing of these mineral-based materials involve a combination of mining, quarrying, and various chemical and physical separation processes. These may include crushing, grinding, washing, and purification methods to obtain the desired purity and quality of the final products.

Production inputs

The main inputs required for the industries under HS code 25 are the raw mineral resources, such as 2501 Salt and pure sodium chloride, 2503 Sulphur of all kinds, 2507 Kaolin and other kaolinic clays, and 2517 Pebbles, gravel, broken or crushed stone. Additionally, these industries may require specialized equipment, machinery, and energy sources to facilitate the extraction, processing, and transportation of these materials.

Production outputs

The industries covered under HS code 25 produce a wide range of outputs, including 2501 Salt and pure sodium chloride, 2503 Sulphur of all kinds, 2517 Pebbles, gravel, broken or crushed stone, 2518 Dolomite, and 2522 Quicklime, slaked lime and hydraulic lime. These products are then consumed by various other industries, such as 28 Inorganic chemicals, 31 Fertilizers, 32 Tanning or dyeing extracts, and the construction sector.
