Sulphur Price Surge: Impact of Geopolitical Conflicts and Green Transition

Key Highlights & Summary

 • International sulphur prices escalated nearly four-fold, rising from $280 per tonne in July 2025 to $1,050 per tonne in July 2026, creating a severe import burden for consumer nations. 

• Approximately 92% of global sulphur supply is produced as a secondary by-product of petroleum refining and natural gas processing, leaving output highly dependent on hydrocarbon supply chains. 

• Geopolitical shocks in key refining regions—including Ukrainian drone strikes on Russian refineries and escalating conflict in West Asia—caused major export restrictions and seaborne supply disruptions.

 • China, Russia, and major West Asian producers restricted sulphur and sulphuric acid exports to prioritize domestic agricultural and industrial needs.

 • India, despite producing 3.7 MMT of sulphur, relies heavily on imports (2.25 MMT in 2025), with over 90% sourced from West Asia to support its domestic fertilizer sector. 

• Beyond traditional fertilizer usage, structural demand is rising due to clean energy transitions, as sulphuric acid is heavily utilized in High-Pressure Acid Leach (HPAL) processing of nickel for electric vehicle (EV) batteries. 

Essential Definitions

 • By-Product Commodity: A secondary product derived from a manufacturing process or chemical reaction, such as elementary sulphur recovered during oil and natural gas desulfurization.

 • High-Pressure Acid Leach (HPAL): An industrial hydrometallurgical extraction process that uses high temperature, pressure, and concentrated sulphuric acid to extract nickel and cobalt from low-grade laterite ores.

 • Structural Deficit: An ongoing market condition where long-term global consumption continuously exceeds total supply capacity regardless of seasonal fluctuations.

 Legal and Constitutional Framework 

• Article 307 of the Indian Constitution: Authorizes Parliament to appoint an authority to regulate inter-state trade and commerce, relevant to managing domestic distribution of essential agricultural inputs.

 • Essential Commodities Act, 1955: Empowers the Union Government to declare fertilizers as essential commodities to control production, supply, distribution, and pricing against global price volatility.

 • Fertiliser (Control) Order, 1985: Promulgated under the Essential Commodities Act to regulate the quality, price, and movement of fertilizers (including sulphur-based nutrients) across India. 

Conclusion The unprecedented surge in global sulphur prices underscores the vulnerability of critical industrial inputs to geopolitical conflict and energy transition demands. Enhancing domestic desulfurization efficiency, expanding strategic reserves, and diversifying mineral processing pathways remain vital to protecting national food security and supporting clean energy manufacturing.
