China’s near‑zero phosphate fertilizer exports and sulfur bottlenecks tighten global supply, raising nutrient and crop price risks for import-dependent regions.
China’s decision to prioritise its domestic fertilizer market has driven phosphate fertilizer exports close to zero in 2026, amplifying an already tight global nutrient balance. The cutbacks, rooted in sulfur shortages and stricter export controls, are pushing import-dependent regions into a higher‑cost environment ahead of key planting seasons. While Chinese urea exports remain relatively stable, the divergence between nitrogen and phosphate markets is sharpening input cost risks for grain producers worldwide.
For agricultural commodity traders and downstream food companies, the shift signals a more structurally fragile phosphate supply chain, with heightened price sensitivity to any additional disruption in sulfur or fertilizer production. Wheat and other cereals face indirect upside risk as farmers reassess application rates and nutrient blends under tighter affordability constraints.
Introduction
According to Argus-based industry reporting, China’s phosphate fertilizer exports in 2026 have collapsed to almost zero from around 5.3 million tonnes in 2025, as sulfur shortages and policy measures channel available output to the domestic market. Beijing has tightened controls on shipments of key phosphate products such as monoammonium phosphate (MAP), diammonium phosphate (DAP) and triple superphosphate (TSP), alongside curbs on sulfuric acid exports, a critical input for phosphate production.
These measures come on top of already elevated fertilizer prices driven by the Iran conflict and disruptions to sulfur flows via the Strait of Hormuz, which have significantly tightened global sulfur and sulfuric acid availability. The result is a squeeze in phosphate fertilizer availability in major importing regions such as Brazil, India and parts of Southeast Asia, where farm sectors are heavily reliant on imported nutrients to support high-yield grain and oilseed production.
Immediate Market Impact
The collapse in Chinese phosphate exports is removing a key flexible supply source from the global market, forcing buyers to bid more aggressively for volumes from North African producers and other exporters. Industry commentary points to growing pressure on the international phosphate market, with affordability indices indicating that phosphates are among the least affordable fertilizers for farmers in recent years.
Freight and basis differentials are already widening as importers in Brazil and South Asia compete for replacement tonnes, while some traders report thinner liquidity and wider bid‑offer spreads for DAP and MAP. At the same time, Chinese urea exports are expected to hold near 6–7 million tonnes in 2026–27, helping to cap nitrogen prices even as phosphate values remain under upward pressure. This divergence could alter nutrient application patterns, with potential agronomic implications for yields and crop quality.

Supply Chain Disruptions
Beijing’s export controls extend beyond finished fertilizers to sulfuric acid, constraining an essential upstream feedstock for phosphate production both at home and abroad. Chinese producers are concentrating available sulfur and acid on domestic phosphate output, limiting their capacity to resume sizable exports despite technically available plant capacity.
Downstream, shortages of sulfur have already triggered production stoppages at Brazilian plants manufacturing MAP, SSP and TSP, tightening local supply and raising dependence on imported product. Port and terminal operators in Brazil, India and Southeast Asia are facing more variable cargo arrivals, with some buyers shifting to shorter‑term purchasing and diversifying suppliers, adding complexity and cost to logistics planning.
Commodities Potentially Affected
- Phosphate fertilizers (DAP, MAP, SSP, TSP) – Directly hit by China’s near‑zero exports and sulfur bottlenecks, leading to tighter supply and elevated prices across key importing regions.
- Sulfur and sulfuric acid – Upstream markets are strained by Middle East disruptions and Chinese export curbs, with prices having surged several‑fold over recent years, feeding through into fertilizer costs.
- Nitrogen fertilizers (urea) – Chinese exports around 6–7 million tonnes in 2026–27 help anchor prices, creating a relative discount vs phosphates and potentially incentivising higher nitrogen use in some regions.
- Cereal crops (wheat, maize, barley) – Higher phosphate costs and limited availability may prompt reduced application rates, especially in import‑dependent countries, increasing upside risk for global grain prices despite currently stable cash wheat indications in some origins.
- Oilseeds and sugar crops – High‑phosphate‑demand crops such as soybeans and sugarcane could see cost inflation and, in marginal areas, area or input cutbacks, affecting exportable surpluses from Brazil and other key producers.
Regional Trade Implications
Brazil, one of the world’s largest importers of phosphate fertilizers, faces a double hit from curtailed Chinese supply and local production issues linked to sulfur shortages, increasing its dependence on Middle Eastern and North African producers such as Morocco’s OCP and Saudi Arabia’s Ma’aden. India and several Southeast Asian countries are also being pushed to diversify sourcing, renegotiate term contracts and consider strategic stockbuilding where finances allow.
Exporters with reliable access to sulfur and phosphate rock, particularly in North Africa and parts of the US, stand to benefit from stronger pricing and market share gains, albeit constrained by their own capacity and logistics. Conversely, small and mid‑sized importers in Africa and South Asia with limited credit access may struggle to secure sufficient volumes, raising concerns over application rates and food security in the 2026/27 and 2027/28 crop cycles.
Market Outlook
In the near term, the phosphate complex is likely to remain tight and volatile as long as Chinese export restrictions and sulfur bottlenecks persist. Traders report that any hint of a policy shift in Beijing or improvement in sulfur flows could trigger sharp price moves, in either direction, given thin spot liquidity and elevated geopolitical risk around the Strait of Hormuz.
Market participants will watch closely for signals on China’s export stance heading into 2027, including potential adjustments to customs controls and sulfuric acid policy. At the farm level, rising phosphate-to-urea price ratios may encourage substitution and more targeted application, with possible yield implications emerging over coming seasons, particularly for wheat and other cereals in high‑input systems.
CMB Market Insight
China’s decision to sacrifice phosphate export volumes to safeguard domestic supply, under conditions of acute sulfur tightness, reinforces the structural vulnerability of upstream fertilizer and nutrient chains. For agricultural commodity markets, this not only sustains elevated fertilizer cost risk but also increases the probability of crop yield surprises and price spikes if weather or geopolitics deliver additional shocks.
Traders, importers and food industry buyers should factor in a prolonged period of asymmetric risk: nitrogen markets cushioned by steady Chinese urea flows, but phosphate markets exposed to concentrated supply and policy uncertainty. Strategic diversification of fertilizer sources, closer monitoring of sulfur and acid logistics, and tighter integration of nutrient cost scenarios into grain and oilseed procurement strategies will be critical to managing volatility through the 2027 horizon.
