Sulfur Supply Chain Disruption Drives Up Fertilizer and Tech Manufacturing Costs

Global sulfur prices have surged in recent months, creating significant challenges for fertilizer producers, nickel miners, and even microchip manufacturers. Disruptions to supply, particularly from the Middle East, are driving up costs and raising concerns about food security and the production of essential technologies.

Sulfur Price Increases: A Global Overview

As of March 13, 2026, sulfur traded flat at 4,750 CNY/T (approximately $656 USD) in China, according to Trading Economics. This represents a 23.91% increase over the past month and an 82.62% increase year-over-year. Prices in Europe have also risen, reaching $410 per ton (approximately $545 USD) in early March, while African prices climbed to $700 per ton at the finish of the previous week.

Middle East Supply Constraints

The primary driver of these price increases is disruption to sulfur supplies from the Middle East, which accounts for almost a quarter of global sulfur production – approximately 84 million tons – and 45% of global exports, as reported by The Financial Times. Kuwait has halted sulfur exports alongside oil, and other Middle Eastern producers are also limiting supply. Logistical challenges are exacerbating the problem, with some producers unable to secure transportation for available sulfur.

Impact on Key Industries

• Fertilizer Production: Sulfur is a critical component in the production of ammonium sulfate and phosphate fertilizers, essential for crop growth. Rising sulfur prices directly translate to higher fertilizer costs, potentially impacting food security, particularly in agriculturally-dependent, low-income countries. Fertilizer manufacturers consume approximately sixty percent of the world’s sulfur supply.
• Nickel Mining: Indonesia, which accounts for over half of the world’s mined nickel, relies heavily on sulfur imports from the Middle East, importing 75% of its sulfur needs from the region. Sulfur stocks in Indonesian companies are limited, sufficient for only one to two months.
• Copper Mining: Southern Africa’s copper miners are also competing for limited sulfur supplies, with approximately 900,000 tons currently in storage, enough for several weeks. The Democratic Republic of Congo alone imported 1.3 to 1.4 million tons in 2025 for copper extraction.
• Microchip Manufacturing: While microchip manufacturers have a relatively smaller sulfur consumption, they are also affected by the supply constraints.

Logistical Bottlenecks and Delivery Issues

The disruption extends beyond production. Approximately 44,000 companies have experienced delays or non-delivery of sulfur orders, according to analysis from Dun & Bradstreet. The blockade of the Strait of Hormuz is significantly impacting the sulfur market, hindering transport routes.

Looking Ahead

The IMARC Group suggests that a significant drop in sulfur prices is unlikely in the near term, as sulfuric acid remains essential for battery production. The situation highlights the vulnerability of global supply chains and the interconnectedness of various industries. Continued monitoring of Middle Eastern geopolitical developments and sulfur supply dynamics will be crucial for businesses and policymakers alike.
