About salt (including table salt and denatured salt); pure sodium chloride whether or not in aqueous solution; sea water

HS code 2501 covers a wide range of salt products, including table salt, denatured salt, and pure sodium chloride. Salt is a crucial mineral that has been an integral part of human civilization for thousands of years, used in food preservation, seasoning, and various industrial processes. The global salt industry plays a significant role in the broader economy, with applications across sectors such as food, chemical manufacturing, and water treatment.

Production process

The production of salt primarily involves the extraction and purification of sodium chloride from natural sources, such as salt mines, salt lakes, or seawater. The most common production methods include solar evaporation, rock salt mining, and solution mining. In solar evaporation, seawater or brine is allowed to evaporate in large, shallow ponds, leaving behind the salt. Rock salt mining involves the extraction of solid salt deposits from underground mines, while solution mining utilizes hot water to dissolve and extract the salt from underground deposits.

Production inputs

The main inputs required for the salt industry include the natural sources of salt, such as seawater, salt lakes, or salt deposits. Additionally, the industry relies on various equipment and machinery for extraction, processing, and packaging, including pumps, evaporation ponds, drying facilities, and packaging equipment. Energy sources, such as electricity or fossil fuels, are also necessary for the production and processing of salt.

Production outputs

The primary outputs of the salt industry are various forms of salt, including table salt, industrial salt, and specialty salts. These salt products are then consumed by a wide range of industries, including 1511 Food processing, 2011 Manufacture of basic chemicals, 3600 Water collection, treatment and supply, and 2023 Manufacture of soap and detergents, cleaning and polishing preparations, perfumes and toilet preparations.
