Phosphoric acid rarely makes headlines, but it sits at the base of global food production. It is the key intermediate behind the phosphate fertilizers that help farmers grow more on limited land, and it is also used in food processing, water treatment, metal finishing and electronics. According to Grand View Research, the market is on a steady growth path through 2033.

Core Market Indicators

The global phosphoric acid market was valued at USD 45.8 billion in 2025 and is estimated at USD 47.6 billion in 2026. It is projected to reach USD 63.6 billion by 2033, a CAGR of 4.2% over 2026–2033.

Asia Pacific led in 2025 with a 50.0% revenue share, and China was the largest national market. Its large farming base, expanding industrial sector and government support for fertilizer use drive both fertilizer-grade and industrial demand.

By application, diammonium phosphate (DAP) led with 33.3% of 2025 revenue, thanks to its high nutrient content and wide use in large-scale agriculture. Monoammonium phosphate (MAP) is the fastest-growing application, at a 4.8% CAGR, helped by precision agriculture, high-value crops and a push toward more efficient nutrient use. Europe is the fastest-growing region at a 4.6% CAGR, supported by strict regulatory standards and rising demand for high-purity, specialty-grade acid.

Structural Drivers & Macro Trends

Food security and fertilizer demand. A growing population, changing diets and shrinking arable land are pushing farmers to raise yields. Fertilizer makers are buying more phosphoric acid as a result, and producers are expanding capacity and strengthening supply chains. Government programs that promote balanced fertilization and modern farming practices add to this demand in both developed and emerging economies.

Specialty and high-purity grades. Beyond agriculture, demand is growing in food and beverage processing, pharmaceuticals, water treatment and electronics. These uses require tighter purity standards and command higher margins. Producers are investing in advanced purification so they can diversify away from commodity fertilizer grades.

Emerging-market momentum. Urbanization, expanding farmland and industrialization across Asia, Africa and Latin America are creating demand for both fertilizer-grade and industrial acid. Producers that build regional capacity and distribution are best placed to capture it.

Raw-material and geopolitical risk. Phosphate rock is concentrated in a small number of countries. Export restrictions, mining regulation, energy costs, logistics and environmental compliance can all squeeze margins and add price volatility. Smaller producers without captive mines or long-term supply contracts feel this most.

Capital intensity and integration. The market is moderately concentrated. Large producers that combine mining, acid production and fertilizer manufacturing hold a cost and supply-security advantage over regional players.

Two recent moves show where the industry is heading:

• April 2025: Jordan Phosphate Mines Company and the Indonesian government agreed to build a new 200,000-ton phosphoric acid plant in Surabaya. It would double the site's output to 400,000 tons a year to meet rising fertilizer demand.
• February 2025: Prayon announced a new production unit at its Bex site to double its electronic-grade phosphoric acid capacity by 2028, targeting semiconductor and advanced electronics customers.

Top Global Market Leaders

The report profiles these companies:

• OCP Group
• The Mosaic Company
• PhosAgro (PJSC PhosAgro)
• Nutrien Ltd.
• ICL Group Ltd.
• Yara International ASA
• IFFCO Group
• Prayon Group
• Aditya Birla Group

Established players: OCP Group, Mosaic, Nutrien, ICL, Yara, PhosAgro and Prayon run integrated value chains from phosphate rock mining through acid and fertilizer production. Their strengths are secure feedstock, large-scale cost-efficient plants and global distribution. Their weaknesses are heavy capital requirements, exposure to environmental regulation and sensitivity to commodity price swings.

• OCP Group is described as a vertically integrated leader. Its large phosphate reserves support cost efficiency and reliable supply, and its investment in research and sustainability serves both fertilizer-grade and industrial demand.
• The Mosaic Company is a major North American producer serving agricultural and industrial customers. It relies on advanced production technology, a strong distribution network and continued investment in capacity and efficiency.

Emerging players: IFFCO Group and Aditya Birla Group focus on regional capacity, local market knowledge, competitive pricing and downstream expansion. Their limits are a smaller global footprint, dependence on external phosphate rock and less capital for specialty products.

The Outlook

Fertilizers will remain the main revenue source. The most attractive opportunities lie with integrated producers that secure phosphate rock, build resilient supply chains and move into higher-value, high-purity grades.
