Ammonium Sulfate Price Trend and Forecast 2026-2027

The US paid the most for ammonium sulfate in Q2 2026: USD 288/MT, up 2.1% from USD 282 in Q1. The steady fertilizer demand kept things firm there, and the sulfuric acid feedstock costs added their own pull on top of that. Worldwide, the average moved up 2.0%, to USD 260/MT from USD 255, largely because the sulfuric acid feedstock costs kept climbing across every region we track. What about H2 2026? We'd expect a global average somewhere in the USD 255-278/MT range, with the fertilizer-sector demand doing most of the work.

Ammonium sulfate is made either by directly reacting ammonia with sulfuric acid, or recovered as a byproduct from caprolactam production and coke-oven gas scrubbing. Its largest use by far is as a nitrogen-and-sulfur fertilizer, valued for correcting sulfur-deficient soils and for how well it performs on the alkaline ground where other nitrogen sources struggle. Three things move the price more than anything else: the sulfuric acid feedstock costs, the byproduct supply from caprolactam and coke-oven operations, and the seasonal fertilizer-sector demand.

The dual nature of this market's supply side makes it a bit unusual among nitrogen fertilizers. A meaningful share of world output isn't produced deliberately as a fertilizer at all, it's a byproduct that shows up whenever caprolactam plants or coke-oven operations run, regardless of what fertilizer demand looks like at the time. That means ammonium sulfate supply doesn't always respond to fertilizer prices the way dedicated fertilizer production would, since the caprolactam and steel producers generating the byproduct are making their output decisions based on their own core businesses, not on the fertilizer market.

On the demand side, the sulfur content is really what sets this fertilizer apart from more common nitrogen sources like urea. Sulfur deficiency has become a more common problem in intensively farmed soils over the past couple of decades, partly because cleaner-burning fuels have reduced the amount of sulfur that used to reach farmland incidentally through atmospheric deposition. That's given ammonium sulfate a growing agronomic case even in regions where it wasn't traditionally a major input, and it's part of why the demand side of this market has stayed resilient even as fertilizer prices overall have been volatile.

Ammonium Sulfate Price Forecast for 2026

Supply and demand should stay moderately tight through H2 2026, with the sulfuric acid costs doing a lot of the work on pricing. The US and Brazil both kept the fertilizer demand steady through H1, and that's likely to continue into the next planting cycle. Germany's coke-oven and caprolactam byproduct supply should stay steady, while China's large production base keeps it the most affordable of the four.

Buyers planning ahead for the next planting season should keep an eye on sulfuric acid pricing specifically, since it's historically been the single best leading indicator for where ammonium sulfate is headed a quarter or two out. The byproduct supply side matters too, though it moves more slowly and is harder to forecast from public data alone.

What could push prices higher? A sulfuric acid feedstock spike, or reduced caprolactam and coke-oven byproduct output. What could pull them lower? A fertilizer-sector demand slowdown, or an unexpected increase in byproduct supply from expanded caprolactam or coke-oven capacity coming online.
