Sulfur Market Size & Share Analysis - Growth Trends and Forecast (2027 - 2032)

Market Trends and Insights

Rising demand from fertilizer manufacturing

Phosphate fertilizer production connects sulfur demand to industrial acid throughput, concentrating the commercial opportunity among large processors. The Mosaic Company purchased approximately 2.9 million long tons of sulfur for its North American phosphate operations in 2025. It used molten sulfur at phosphate concentrates plants to produce sulfuric acid, primarily for P2O5 production. Separately, PhosAgro's production of phosphate-based fertilizers and feed-grade MCP rose 5.5% year over year to 9.36 million metric tons in 2025.^[1] Because Mosaic converts molten sulfur at its own phosphate concentrates plants, phosphate-driven demand reaches suppliers as liquid acid-plant feedstock, making delivery form part of the fertilizer opportunity.

Expansion of ultra-low-sulfur diesel (ULSD) refining capacity

Cleaner diesel investment supports sulfur trade through recovery capacity. Petrobras produces liquid and solid elemental sulfur by transforming acidic gas from hydrotreatment units used to make ultra-low-sulfur fuels. On May 27, 2025, Petrobras brought a diesel hydrotreatment unit online at Replan in Paulínia, Brazil, adding up to 63,000 barrels per day of S-10 diesel capacity. Petrobras's 2026-2030 plan projects 307,000 barrels per day of additional Brazilian S-10 capacity by 2030, including projects under evaluation. Its potential 2025 allocation assigned 104,000 of 112,000 barrels per day to S-500 replacement at Replan and Revap, with actual S-10 production dependent on market conditions. Because Petrobras converts hydrotreatment acidic gas into elemental sulfur for industrial use, added S-10 processing can provide a recovery stream around which industrial buyers can structure supply contracts.

Increasing sulfur usage in rubber vulcanization

Vulcanization gives sulfur suppliers exposure to recoveries in the production of rubber goods. In 2025, Japan's tire industry used 930,000 metric tons of rubber in tire production. Tire output reached 123.3 million units, with both output and rubber use exceeding the prior year for the first time in 4 years. Where additional tires use sulfur-cured compounds, higher production can expand the requirement for vulcanizing material. Global tire-industry rubber consumption was estimated at 17.86 million metric tons in 2025, down 1% from 2024. Sulfur sellers serving Japanese tire-compound makers thus have a local production recovery to address, while a broader demand impulse depends on recovery extending beyond Japan.

Commercialization of lithium-sulfur batteries for e-mobility

Gelion, Nissan Technical Centre Europe and the University of Oxford announced a grant-funded, 3-year UK project commencing in June 2026 to develop sulfur-based solid-state batteries for EV applications. The planned battery pack targets automotive performance, safety and manufacturability requirements, bringing vehicle specifications into cathode development. Meeting those requirements is the step that could make sulfur-based cells relevant to vehicle manufacturing. For sulfur suppliers, the demand mechanism runs through subsequent cell production rather than the research award itself. Any recurring material requirement depends on later scale-up, placing this opportunity at the long end of the forecast horizon.

Stringent SOx-emission regulations across regions

Emission limits condition the downstream acid capacity through which elemental sulfur reaches industrial users. China's GB 26132-2010 set a 400 mg/m³ sulfur dioxide exhaust limit for newly built sulfuric-acid facilities, including sulfur-burning plants. The limit took effect on March 1, 2011, making compliance an established condition for new capacity. EPA's 2025 Idaho haze action recorded a 2024 state estimate of about USD 8,000 per ton of SO2 removed for prospective wet scrubbing at ITAFOS Conda LLC's sulfur-burning acid plant. EPA did not require the retrofit, accepting Idaho's rejection because estimated costs exceeded its USD 6,100-per-ton threshold. Emissions controls therefore enter the investment case for sulfur-burning acid capacity, even when the feedstock itself is available.

High logistics and handling cost for molten sulfur

Molten sulfur can be available overseas while the delivered product is uneconomic for industrial buyers. In 2025, high logistics costs made imported liquid sulfur unworkable for many European chemical companies facing subdued downstream markets. Moving the liquid over long distances required heating and dedicated transport, which ruled out backhaul offsets. European buyers had increasingly turned to imported liquid sulfur, extending their exposure to this freight burden. For the affected chemical companies, delivered import prices ran much higher than local cost-and-freight prices, leaving a cost gap precisely where greater reliance on imports brought more supply through the expensive route.

Sulfur Market Segment Analysis

Solid represented an 80.94% sulfur market share in 2026 and is the largest and fastest-growing segment, with a projected 4.75% CAGR during 2027-2032. In 2025, Martin Midstream Partners' Beaumont, Texas, facility had combined capacity to process 5,500 short tons of molten sulfur per day into prills and granules. The company stores formed sulfur in bulk before selling it into local or international agricultural markets. This combination of industrial forming and agricultural distribution connects recovered material to a commercial channel that can serve customers across different locations.

Serving that agricultural outlet also creates a role for sulfur-forming services alongside product sales. Martin Midstream Partners' sulfur-forming service contracts are fee based and typically include minimum fee guarantees. The contracts therefore tie forming income to the processing service, giving operators a different financial exposure from the price of the sulfur sold. The typical fee floor can help operators carry solid-sulfur forming capacity through throughput swings while maintaining the link to agricultural demand.

Granules accounted for a 74.77% share of the sulfur market size in 2026 and are the largest and fastest-growing segment, with a projected 4.85% CAGR during 2027-2032. Enersul operates sulfur-handling facilities in Western Canada through company-owned operations and contracts to manage third-party facilities. Its operating portfolio includes GX granulation alongside other forming and handling processes. Granulation therefore has a commercial service role within a network of sulfur operations, providing a route for producers to use specialist forming capabilities.

At OQ8's Duqm refinery in Oman, the March 2026 configuration linked granulation operation directly to the refinery's daily sulfur stream. The site had 3 IPCO SG20 drum granulators, with 2 operating at a time at 450 metric tons per day each to meet the stated daily production need of 900 metric tons. Each unit's design capacity was 800 metric tons per day, giving the 2 operating units combined design capacity of 1,600 metric tons per day. The distinction between operating duty and design capacity makes coordination with refinery production central to how the granulators are run.

Fertilizer was the largest segment, accounting for 88.32% of sulfur volume in 2026. OCP produced 13.9 million metric tons of phosphate-based fertilizer in 2025. The group's sulfuric acid production uses sulfur as its principal raw material, and that acid is required to produce its phosphoric acid. A significant part of the phosphoric acid is further processed into phosphate-based fertilizers. OCP's integrated pathway makes acid production a direct point of exposure for sulfur sellers serving the group's broader fertilizer operation.

Chemical processing is the fastest-growing segment, with a projected 5.05% CAGR during 2027-2032. The Thacker Pass joint venture, 62% owned by Lithium Americas, was developing sulfur-burning acid plants in Nevada in 2026. Those plants were designed to burn delivered liquid elemental sulfur and provide acid for lithium-carbonate chemical production. On-site acid production would make liquid-sulfur receipt part of the lithium plant's operating sequence. Commissioning the acid facilities would turn this designed sulfur requirement into an operating feedstock need.

Geography Analysis

Asia-Pacific Sulfur Market

Asia-Pacific accounted for a 39.68% share of the sulfur market size in 2026 and is the largest and fastest-growing geography, with a projected 5.15% CAGR during 2027-2032. Indonesia imported 5.35 million metric tons of sulfur in 2025, up 48% from 3.62 million metric tons in 2024.^[2] Argus linked the rise largely to 2 newly commissioned sulfur burners at battery-materials producer QMB New Energy Materials. These installations illustrate how downstream materials investment can translate into additional import requirements for the feedstock. At full capacity, the 2 burners together require around 553,000 metric tons of sulfur per year, concentrating suppliers' exposure in identifiable conversion assets.

North America combines Canada's export supply with US demand for sulfur used in phosphate extraction, copper leaching and other industrial processing. Canada exported 4.33 million metric tons of crude or unrefined sulfur in 2025, with the United States, China, Australia and Indonesia among its leading destinations. Europe's cross-border trade includes Poland, which exported 0.19 million metric tons of crude or unrefined sulfur in 2025, serving destinations including Germany, Austria, Belgium and the Czech Republic. These patterns suggest different commercial exposures, with Canadian exporters shipping to the United States as well as to Asian and Australian buyers, and Polish sellers supplying buyers across Central and Western Europe.

South America presents an import opportunity in Brazil, which imported 2.32 million metric tons of crude or unrefined sulfur in 2025. Brazil's suppliers included the United States, Saudi Arabia, the United Arab Emirates and Qatar. Within Middle-East and Africa, Saudi Arabia exported 0.87 million metric tons of crude or unrefined sulfur in 2025. China, India, Morocco and Egypt were among its leading destinations. Brazil's supply options span North America and the Gulf, whereas Saudi exporters' named destinations link their sales to Asian and North African buyers.

Regulatory Framework and Outlook

Selected jurisdictions are compared from the perspective of pulp, paper and paperboard mill operators handling elemental sulfur. Sulfur-burner houses make these mills a defined industrial user group with sulfur-specific workplace obligations in the United States. China's hazardous-chemical framework governs covered storage and use, so the comparison concerns safety management at the mill's sulfur-handling operation.

China's Medium rating reflects mill duties under the law effective May 1, 2026, and the Ministry of Emergency Management (MEM) August 2026 chemical-sector inspection framework, with legal references updated through July 31, 2026. In September 2026, MEM, the National Financial Regulatory Administration and the National Mine Safety Administration targeted 100% liability-insurance coverage by year-end 2026 for high-risk enterprises under emergency-management or mine-safety oversight, leaving the underlying sulfur classification and handling law intact and supporting No change. For US pulp, paper and paperboard mills, OSHA's 29 CFR 1910.261 requires ventilation and precautions against dust explosions and fires at sulfur-burner houses, nonsparking tools and equipment for dry sulfur, bins free of sulfur-dust accumulation and sulfur-melting equipment outside burner rooms. OSHA's Standards Improvement Project 2025 is a broad, long-term standards review, including part 1910, with a proposal projected for July 2027, supporting US Medium/No change for operative mill duties pending that proposal.

Value Chain Stages

This comparison follows sulfur through production, forming, inland movement and marine export loading. Tengizchevroil produces sulfur alongside oil and gas as part of its integrated hydrocarbon operation. Specialist granulation equipment and logistics services create additional commercial roles between recovery and the final buyer. At the export handoff, forming and terminal throughput determine whether recovered sulfur can become a deliverable sales commitment.

Product sales and service fees capture value at different points in this chain. In 2025, Martin Midstream Partners' Sulfur Services segment reported USD 147.6 million in product sales against USD 16.44 million in service revenue, making fees a smaller revenue layer alongside product sales.^[3] Pacific Coast Terminals operates a bulk sulfur and potash berth at Port Moody, British Columbia, with an April 1, 2026, tariff pricing sulfur railcar storage and reclaim-to-vessel operations. At the terminal stage, vessel-size limits subject to arrival-draft restrictions determine which vessels the berth can accept, making compatible vessel scheduling a condition for earning loading fees.

Key Opportunities for Market Participants

Prospective sulfur opportunities cover Indorama Misr Fertilizers Company's proposed phosphate complex at Ain Sokhna, Egypt, and McEwen Copper's planned Los Azules copper project in San Juan, Argentina. Indorama Holdings B.V., an Indorama Corporation subsidiary, seeks financing for the Egyptian complex, whose May 2026 design specifies maximum sulfur imports of 350,000 metric tons per year through Sokhna Port. Los Azules specifies elemental sulfur for on-site acid supporting heap leaching, and McEwen Copper's August 2026 update expected a final investment decision and full financing in mid-2027, with commercial copper cathode production targeted for 2030 subject to financing and customary approvals.

New industrial conversion capacity is the central opening, because both project designs specify elemental sulfur as a process input. Los Azules presents the nearer-dated planning opportunity because its final investment decision and full financing were expected in mid-2027, while the Indorama complex is proposed and seeking financing. An elemental-sulfur offer for on-site acid could be prepared around that expected decision, with delivery commitments conditional on financing, customary approvals and the targeted 2030 production start.
