Is now a good time to secure agricultural supplies despite global trade uncertainty?

China and Russia restricted sulfur exports in 2026, tightening global supplies of a primary input for phosphate production. These trade blocks directly increased the cost of manufacturing fertilizer in the United States compared to previous years.

Why it matters

The reduction in sulfur availability disrupted supply chains for essential agricultural inputs, shifting cost structures for manufacturers and downstream farming operations. This volatility emerged as key global suppliers restricted access to material that is critical for phosphate-based fertilizer.

Current U.S. sulfur costs for producing a ton of DAP fertilizer have exceeded levels seen in both 2022 and 2023. These increases follow a period of lower pricing during the summer of 2026.

The players

China

A major global economy and key participant in the international sulfur export market.

Russia

A top-tier global commodity exporter currently restricting international access to its sulfur supply.

The details

Sulfur serves as a critical component in the production of diammonium phosphate (DAP), a widely used fertilizer. When major producers like China and Russia restrict exports, manufacturers face sudden scarcity, forcing costs higher. This supply-side constraint ripple-effects throughout the agricultural sector, as fertilizer producers pass these elevated input costs onto farmers planning for upcoming planting cycles.

Timeline

  1. 2022 served as a baseline for comparing production costs.

  2. 2023 served as a baseline for comparing production costs.

  3. Summer 2026 was the period when sulfur-based fertilizer products were priced low.

  4. 2027 spring is the upcoming season for which farmers are planning.

Market Landscape

This trend marks a shift from the historically low sulfur prices observed in the summer of 2026. It follows the pattern of the 2022 fertilizer price volatility by tightening supply and raising production costs.

Operators in the agricultural space should anticipate continued price pressure on inputs ahead of the 2027 spring planting season. Managers should evaluate current inventory levels and consult with accounting teams regarding the impact of these cost increases on seasonal budget forecasts.

The takeaway

Global supply constraints on sulfur have fundamentally altered the cost baseline for fertilizer production compared to recent years. Agribusiness operators should monitor international trade policies in China and Russia to anticipate further volatility for the 2027 spring planting cycle.
