Sulfuric acid prices hit crisis levels after China banned exports starting May 1, 2026. Two devastating supply shocks converged this spring to create the worst commodity crisis since 2008, paralyzing global mining, fertilizer production, and manufacturing.
🔥 Quick Facts
- Sulfuric Acid Prices: CFR US Gulf surged to $400/mt on May 6, 2026, from $155/mt in late February, a 158% spike in just 10 weeks
- China’s Role: World’s largest producer with 40% global output banned all exports effective May 1, removing 4.6 million metric tons annually
- Hormuz Closure: Middle East shipping disruptions since February 2026 blocked half of global seaborne sulfur exports, the first major shock
- Market Impact: This is the worst supply crisis in commodity markets since the 2007-2008 food and fertilizer collapse
China’s Export Ban Triggers Global Supply Shock
On April 10, 2026, China announced it would halt sulfuric acid exports starting May 1, marking a monumental shift in global supply chains. The ban affects acid generated from copper and zinc smelting operations, with limited exceptions for electronic-grade material. Beijing justified the move by citing the need to protect domestic phosphate fertilizer production and food security amid rising global demand.
China exports approximately 4.6 million metric tons annually, accounting for roughly 37% of Chilean imports, the world’s largest importer. In March 2026, Chinese shipments to Chile dropped to zero from 151,268 metric tons just 12 months earlier. The restriction follows an earlier quota system that slashed export allowances from 1.3 million metric tons in January-April 2025 to just 700,000 metric tons in the same period of 2026.

The timing could not be worse. Chile depends on sulfuric acid for heap leaching operations that produce roughly 20% of the country’s refined copper output, approximately 1.1 million metric tons annually. With half of H2 2026 import needs uncovered, Chilean miners face a desperate scramble for alternative sources as planting seasons approach globally.
Middle East War Disrupts Half of Global Supply
Before China’s ban took effect, the Strait of Hormuz closure devastated sulfur availability. Since late February 2026, escalating regional conflict involving Iran effectively shut commercial shipping through the critical chokepoint. The Middle East produces roughly one-third of global sulfur and controls approximately 50% of seaborne trade flows.
Prices doubled in under seven weeks as buyers rushed to secure inventory. Chilean CFR Mejillones benchmarks climbed from $190/mt on February 25 to $300/mt on April 8, then $380/mt on April 15. US Gulf prices nearly tripled in the same window, reaching $400/mt by early May. Brazil saw delivered prices explode to $1,000 to $1,400 per metric ton, while Zambia introduced a permanent permit system on March 27, 2026, citing critical domestic shortages.
The Middle East disruption, compounded by China’s regulatory move, created a supply deficit exceeding 4 million metric tons that cannot be quickly offset. Japan, South Korea, and India combined could increase output by only 500,000 metric tons, while new acid production capacity requires 18 to 24 months from permitting to full operation.
| Metric | Value or Impact |
| Global Supply Loss | Approximately 6.4 million metric tons annually from China ban plus Hormuz closure |
| US Gulf Price (May 6, 2026) | $400/mt, up from $155/mt February 25 |
| Brazil Delivered Price | $1,000 to $1,400/mt, more than double pre-crisis levels |
| Alternative Supply Capacity | Japan, Korea, India combined: only 500,000 mt increase possible |
Fertilizer Crisis Threatens Food Security and Crop Failure
Sulfuric acid is essential for phosphate fertilizer production, making this chemical shortage directly threaten agricultural output worldwide. Brazil entered its critical planting season in May 2026 with sulfuric acid prices at crisis levels, squeezing fertilizer manufacturer margins to unsustainable levels.
According to market observers on the ground, the situation is dire. Sources in Brazil warned that without affordable sulfuric acid-based fertilizers, “there will be a crop failure.” Desperate Brazilian buyers imported roughly 800% year-over-year more sulfuric acid in March, seeking European cargoes, but Europe is now effectively sold out until June. The availability squeeze arrives precisely when farmers need to apply fertilizers for key planting windows.
Copper miners in Chile, Peru, the Democratic Republic of Congo, Zambia, and Indonesia all face similar crunch scenarios. Mining operations that depend on sulfuric acid for leaching chemistry cannot maintain production at current price levels, forcing operational reductions that ripple through global metal supply chains and downstream manufacturing.
2008 Price Crisis Echoed in Markets Today
The current disruption mirrors the commodity shock of 2007-2008, when sulfuric acid prices surged as global demand outpaced supply during the world food crisis. Back then, sulfuric acid prices spiked due to fertilizer demand, but recovered relatively quickly once demand moderated. Today’s crisis combines geopolitical shock with deliberate government export restrictions, creating a fundamentally different dynamic.
Akin Gump, a major international law firm focused on commodity disputes, described the current situation as “a supply shock not seen since 2008.” Unlike the 2008 crisis, which was demand-driven, today’s disruption stems from two independent but simultaneous events: a regional conflict closing a chokepoint that carries 50% of global seaborne sulfur, and a major producing nation’s export ban removing 4.6 million metric tons annually.
The magnitude of the shock has left long-term supply contracts in legal and commercial limbo. Copper smelters and fertilizer makers operating under fixed-price agreements signed when sulfuric acid cost $150 to $160 per metric ton now face suppliers asking prices above $400. Force majeure claims, hardship doctrines, and commercial renegotiation are all in play across multiple jurisdictions and contract types.
When Will Sulfuric Acid Prices Return to Normal?
Market participants express deep uncertainty about recovery timelines. The Hormuz closure could persist through 2026 depending on geopolitical resolution. China’s export ban appears intended to be permanent policy, not a temporary measure. Alternative suppliers in Canada, Japan, and Korea are already running at capacity, and new production facilities take 18 to 24 months to build and ramp up.
In the near term, expect continued rationing, negotiated allocations, and pricing chaos. Miners and fertilizer producers with exposure to long-term contracts are exploring renegotiation, temporary volume reductions, and deferred deliveries. Those with spot-price contracts face brutal immediate cash flow pressure as they compete for increasingly scarce inventory at three to four times pre-crisis prices.
The real question is whether global supply chains can absorb the shock or whether crop failures, mining shutdowns, and cascade defaults through offtake agreements and project finance documentation will amplify the crisis further. The answer will define 2026 commodity markets.
