Global Salt Industry: Rising Demand, Expanding Capacities, and Key Market Trends

Executive Summary
The global salt industry is experiencing dynamic changes driven by increasing industrial demand, particularly in the Asia-Pacific region. Key developments include:

• Australia’s Solar Salt Expansion: Significant investments in projects like the Mardie Salt Project (5.35 million tonnes/year) and Eramurra Salt Project (2 million tonnes/year) are bolstering Australia’s position as a key supplier of high-purity industrial salt. Established producers like Rio Tinto Dampier Salt and Mitsui-Shark Bay Salt contribute substantially to the country’s annual capacity of over 16 million tonnes.
• India’s Salt Industry: Gujarat, which accounts for 75% of India’s salt production, produced approximately 30 million tonnes in 2023. Key exporters such as Friends Salt Works, Archean Chemical and Rankers International are meeting growing global demand, particularly from Far East Asia and China’s industrial sector. However, challenges like seasonal weather impacts due to monsoons and price volatility persist.
• Mexico’s Production Challenges: Exportadora de Sal S.A. (ESSA), producing 8 million tonnes annually, continues to supply key markets in Asia, despite a 30% decline of shipped volume in early 2024 due to operational challenges.
• China’s Industrial Demand: China remains the largest consumer of salt globally, importing approximately 10 million tonnes in 2023 to meet demand for the chlor-alkali industry. Australia and India are its major suppliers.

The global salt market, driven by demand from the chlor-alkali and soda ash industries, is expected to grow further. New projects and expansions aim to address supply challenges and meet rising demand.

Recent Developments in Global Salt Production and Demand

Solar Salt Production Overview
Australia, India, and Mexico are pivotal players in the global solar salt industry, with substantial production capacities and ongoing projects aimed at meeting increasing global demand. While these nations continue to innovate and expand their operations, each faces unique challenges and opportunities shaped by geographic, climatic, and economic factors.

Australia’s Solar Salt Expansion
Australia is aggressively expanding its solar salt production capacity, leveraging its proximity to Asia to maintain its position as a key supplier of high-purity industrial salt. Major developments include:

• Mardie Salt Project: Aiming to produce 5.35 million tonnes annually, it is set to become one of the largest solar salt operations globally by 2027.
• Rio Tinto Dampier Salt: Australia’s largest producer with an annual capacity of 8.8 million tonnes, including:
  • Dampier Operation: 4.5 million tonnes/year
  • Port Hedland Operation: 2.5 million tonnes/year
• Lake Macleod Operation: 1.8 million tonnes/year (recently sold to Leichhardt ).
• Eramurra Salt Project: Leichhardt is developing this project, which is expected to contribute 2 million tonnes annually upon completion.

• Additionally, Mitsui-Shark Bay Salt operates two major mines:
  • Shark Bay Operation: 1.4 million tonnes/year
  • Onslow Operation: 2.3 million tonnes/year

These projects reinforce Australia’s strategic position as a reliable supplier of high-purity industrial salt, particularly to Asian markets.

India’s Salt Production Challenges and Opportunities
India’s salt production experienced significant growth in 2022, driven by record-breaking exports exceeding 13 million tonnes per annum (Mtpa), primarily to China, and strong domestic consumption for edible use and industrial applications. Production in Gujarat, which contributes 75% of the country’s output, rebounded despite earlier weather disruptions. Key players like Archean Chemicals and Tata Chemicals expanded capacities to meet rising demand, with Archean targeting an increase from 3.6 Mtpa to 5.1 Mtpa and Tata Chemicals (little export) expanding to ~1.95 Mtpa. Domestic consumption grew by 7%, while operational improvements and enhanced infrastructure, such as increased washing capacities, are expected to drive further growth. India’s strong export performance and expanding production capacity position it as a vital supplier to the global salt market, particularly for industrial applications like chlor-alkali and soda ash production.

Key export producers and their capacities include:

• Friends Group: 3.0–5.0 million tonnes/year
• Archean Chemical: 3.6–5.1 million tonnes/year
• Rankers International: 2.5–3.5 million tonnes/year
• Neelkanth Group: 1.5–3.0 million tonnes/year
• Chowgule: 0.18–0.2 million tonnes/year
• Others: 10.0–14.0 million tonnes/year

Despite challenges such as extended monsoon seasons delaying solar salt harvests, India’s salt industry continues to adapt and meet growing global demand, particularly from China, Indonesia, and the Middle East.

Mexico’s Salt Industry Developments
Mexico, led by Exportadora de Sal S.A. (ESSA), is a significant contributor to the global sea salt market. Recent developments include:

• ESSA Production: Produces 8 million tonnes annually, playing a crucial role in global supply chains.
• Operational Challenges: ESSA experienced a 30% drop in production and 44% lower sales in early 2024 due to operational disruptions.
• Export Markets: Mexico remains a vital supplier for industrial salt consumers in Japan, China, and other Asian countries.

ESSA’s production is strategically important for global soda ash and chlor-alkali industries, ensuring a steady supply despite challenges.

China’s Growing Salt Demand
China’s demand for salt remains unparalleled, driven by its massive industrial sector and reliance on imported high-purity salt for chemical manufacturing. Key trends include:

• Industrial Applications: The chlor-alkali industry is the primary driver of salt consumption, supporting the production of chlorine, caustic soda, and soda ash.
• Import Sources: Australia and India are major suppliers of industrial salt to China, with imports totaling approximately 10 million tonnes in 2023.
• Market Growth: Rising industrial output and expansions in the chlor-alkali sector are expected to drive further increases in salt imports in 2024 and beyond.

Global Salt Market Trends
The global salt market remains robust, with an estimated 330 million tonnes consumed annually. The market dynamics are influenced by:

• Primary Consumers: The chlor-alkali and deicing sectors dominate global salt demand.
• Asian Growth: The Asia-Pacific region, particularly China and India, continues to experience rapid growth in salt consumption.
• Supply Challenges: Climate variability and supply disruptions in key regions, including India and Mexico, have led to temporary shortages.
• Future Projections: The global salt market is expected to expand further, driven by industrial growth and increasing demand for high-purity salt in chemical manufacturing.

Conclusion
The global salt industry is evolving, shaped by expanding capacities in Australia, sustained growth in India, and challenges faced by Mexico’s ESSA. India has solidified its position as a key global producer, with production reaching approximately 30 million tonnes in 2023, driven by solar salt operations, record-breaking exports exceeding 13 million tonnes, and growing domestic demand. Meanwhile, China’s increasing reliance on imported industrial salt underscores its role as a key driver of global trade. With new projects like Australia’s Mardie Salt Project and Leichhardt’s Eramurra Salt Project, alongside India’s robust production and capacity expansions by major players, the salt market is poised for significant growth to meet the rising demands of industrial sectors worldwide.
