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 broad category includes common salt, sulphur, earths, stone, plastering materials, lime, and cement. These materials play a crucial role in the global economy, serving as key inputs for a wide range of manufacturing processes, infrastructure development, and agricultural applications. The industries covered under this code contribute significantly to economic growth and development worldwide.

Production process

The production techniques for the industries covered under HS code 25 vary depending on the specific product. For example, salt is typically extracted from natural salt deposits or produced through the evaporation of seawater or brine. Sulphur is often obtained as a by-product of oil and gas refining or mined from natural deposits. Earths and stones are quarried or mined, while plastering materials, lime, and cement are produced through the processing and refinement of various mineral resources.

Production inputs

The main inputs required for the industries under HS code 25 include raw materials such as salt, sulphur, various types of earths and stones, as well as energy sources, machinery, and specialized equipment for extraction, processing, and manufacturing. Additionally, these industries may rely on transportation infrastructure, skilled labor, and research and development to improve production methods and product quality.

Production outputs

The industries covered by HS code 25 produce a wide range of outputs that are consumed by various other industries. These include 27 Mineral fuels, mineral oils and products of their distillation; bituminous substances; mineral waxes, 31 Fertilizers, 32 Tanning or dyeing extracts; tannins and their derivatives; dyes, pigments and other coloring matter; paints and varnishes; putty and other mastics; inks, 68 Articles of stone, plaster, cement, asbestos, mica or similar materials, and 69 Ceramic products.
