Where Is Salt Manufactured? Top Salt Producing Countries
Salt is one of the most widely produced minerals on Earth. In 2024, approximately 295 million tons of salt were produced worldwide, used across industries from food processing and chemical manufacturing to road de-icing and water treatment. But where is salt manufactured, and which countries dominate global production?
Where Is Salt Manufactured in the World?
Salt is manufactured on every continent except Antarctica, using three main production methods depending on geography and climate — underground mining, solar evaporation, and vacuum evaporation from brine. The location of production depends largely on natural resources: coastal countries favour solar evaporation, while landlocked regions with geological salt deposits rely on mining.
The countries with the highest volumes of production in 2024 were China (66 million tons), the United States (38 million tons) and India (30 million tons), together comprising 46% of global production. Germany, Australia, Chile, Canada, Mexico, Brazil and Turkey comprised a further 23%. IndexBox

Top Salt Producing Countries
China: World’s Largest Salt Producer
China leads global salt production by a significant margin. China yields around 64 million metric tons of salt annually. The country is home to substantial salt flats in Inner Mongolia, Ningxia, and similar regions, relying on a combination of evaporation and brine extraction techniques. World Population Review
China’s salt is primarily used for chemical manufacturing — chlorine and caustic soda production — and food processing for its enormous domestic market.
United States: Second Largest Producer
Domestic production of salt in the USA was an estimated 40 million tons in 2024, produced by 26 companies operating 64 plants in 16 states. The top producing states were Kansas, Louisiana, Michigan, New York, Ohio, Texas, and Utah, which produced about 95% of the salt in the United States. USGS
Highway de-icing accounted for about 41% of total salt consumed, while the chemical industry accounted for about 39% of total salt sales. USGS

India: Third Largest Producer
India’s sprawling coastline yields large quantities of salt — enough to make it the world’s third-largest salt-producing country, producing over 30 million metric tons annually. India relies primarily on solar evaporation along its western coastline, particularly in the states of Gujarat and Rajasthan. World Population Review
Other Major Producers
Germany, Australia, Chile, Canada, Mexico, Brazil and Turkey are also significant producers, together comprising 23% of global production. IndexBox
Australia and Chile are notable for their large solar evaporation operations, while Germany is a major producer of vacuum evaporated salt for industrial and food applications.
How Is Salt Manufactured? Main Production Methods
Where salt is manufactured depends largely on the production method used:
- Underground mining (rock salt)
Salt deposits formed from ancient dried seas are extracted by drilling and blasting underground. Common in the USA, Germany, Canada and Poland. The resulting product is rock salt — less refined but suitable for de-icing, water treatment and industrial use. - Solar evaporation (sea salt)
Seawater is channelled into shallow ponds where sun and wind evaporate the water, leaving salt crystals behind. Used extensively in India, Australia, Chile, Mexico and Mediterranean countries. Low energy cost but dependent on climate. - Vacuum evaporation (vacuum salt)
Brine is purified and evaporated under controlled pressure in sealed vacuum pans, producing ultra-pure sodium chloride. Used for food-grade, pharmaceutical and high-specification industrial applications. Common in Germany, the UK and the Netherlands.
Where Is Salt and Stone Manufactured?
Salt & Stone is a personal care brand that uses mineral-rich salt in its products. The brand is based in the United States, where its formulations are developed, though specific manufacturing locations for individual products are not publicly disclosed. If you are looking for information about industrial salt manufacturing — the raw material used in chemical, food and de-icing applications — the major production countries are China, the USA and India as outlined above.
Which Country Has the Largest Salt Reserves?
Salt reserves are distributed globally, but the largest known deposits are found in the USA, Canada, China, Germany and India. The quality and quantity of naturally occurring geographic salt deposits is perhaps the most impactful factor affecting global salt production from one country to the next. World Population Review
The USA holds some of the world’s largest underground salt deposits, particularly in the Michigan Basin and the Gulf Coast region, where salt domes extend thousands of metres underground.
