Magnesium Sulfate Price Trend and Forecast 2026-2027

Germany paid the most for magnesium sulfate in Q2 2026: USD 450/MT, up 2.0% from USD 441 in Q1. The steady agricultural and pharmaceutical demand kept things firm there. Worldwide, the average moved up 1.9%, to USD 376/MT from USD 369, largely because the magnesite and 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 370-400/MT range, with the steady agricultural and pharmaceutical demand doing most of the work.

Magnesium sulfate is made by reacting magnesite ore, or magnesium oxide, with sulfuric acid, producing a compound sold across several hydration states depending on the application: the heptahydrate form, known commonly as Epsom salt, for agricultural and bath-product use, the monohydrate, or kieserite, form for agricultural fertilizer blending, and USP-grade material for pharmaceutical injectable and oral use. Three things move the price more than anything else: the magnesite and sulfuric acid feedstock costs, the agricultural-sector demand tied to fertilizer and soil-amendment use, and how much production capacity the producers are running.

The multiple hydration states this compound comes in deserve some explanation, since they effectively define separate sub-markets within this broader commodity. Heptahydrate Epsom salt dominates the agricultural and consumer-product trade, while the monohydrate kieserite form is preferred in some fertilizer-blending applications for its lower water content and different dissolution characteristics. Producers can shift their output mix between these forms to some degree depending on which application is showing stronger demand at a given time, which adds a layer of flexibility to how this market responds to shifting end-use trends. Buyers new to this market sometimes underestimate how much that structural detail matters until they see it play out in the pricing data over a full cycle.

The agricultural application deserves particular attention, since it's the dominant demand driver for this market by volume. Magnesium sulfate corrects magnesium deficiency in soils, a nutrient essential for chlorophyll production and overall plant health, which has made it a routine input for growers managing crops on magnesium-poor soils, tying a substantial share of demand to the broader agricultural planting and fertilization cycle each season.

Magnesium Sulfate Price Forecast for 2026

Supply and demand should stay moderately tight through H2 2026, with the magnesite and sulfuric acid feedstock costs doing most of the work on pricing. Germany and the US both kept the agricultural and pharmaceutical demand steady through H1, and that's likely to continue. India's agricultural sector kept the demand building, while China's large production base kept it the most affordable of the four. None of the four markets we track is showing signs of genuine disruption heading into the back half of the year.

Buyers should keep an eye on the broader magnesite and sulfuric acid markets specifically, since both feedstocks can move for reasons unrelated to magnesium sulfate demand directly, given how widely each is used across other industrial applications.

The agricultural planting-season timing bears watching too, since magnesium sulfate demand tends to track fertilizer-purchasing cycles fairly closely across the major growing regions.

What could push prices higher? A magnesite or sulfuric acid feedstock spike, or a stronger-than-expected agricultural demand surge. What could pull them lower? A slowdown in agricultural-sector fertilizer purchasing more broadly.

Magnesium Sulfate Prices Q2 2026:

• China: USD 301/MT
• United States: USD 408/MT
• Germany: USD 450/MT
• India: USD 365/MT

Magnesium Sulfate Prices in China

China's magnesium sulfate producers passed through the firmer feedstock costs this quarter, and the domestic agricultural demand held steady. The gain came to 2.0%, USD 295/MT to USD 301. That kept China comfortably the most affordable of the four markets.

Why did the price of Magnesium Sulfate change in Q2 2026 in China?

The magnesite feedstock costs firmed through the quarter, and the domestic agricultural demand held its ground right alongside that.

Magnesium Sulfate Prices in United States

USD 408/MT. That's where the US landed in Q2, up 2.0% from USD 400 in Q1. The pharmaceutical demand stayed steady, and the feedstock costs climbed just enough to push things higher.

Why did the price of Magnesium Sulfate change in Q2 2026 in United States?

The pharmaceutical demand didn't move much, honestly. It was the magnesite and sulfuric acid feedstock costs doing most of the work this quarter.

Magnesium Sulfate Prices in Germany

Germany gained 2.0% to USD 450/MT, the established agricultural demand staying firm through the period.

Why did the price of Magnesium Sulfate change in Q2 2026 in Germany?

Germany's premium held for the usual reason: steady agricultural demand backed by firming feedstock costs.

Magnesium Sulfate Prices in India

India climbed 2.0% to USD 365/MT, the agricultural-sector demand continuing to build through the period.

Why did the price of Magnesium Sulfate change in Q2 2026 in India?

The agricultural-sector demand kept building, and that alone explains most of the move here.

Quarterly Magnesium Sulfate Price Trends

The global average climbed steadily across the window, from USD 350/MT in Q1 2025 to USD 376 by Q2 2026, a net gain of about 7.4%. Every quarter posted a gain here, reflecting the firming magnesite and sulfuric acid feedstock costs and the steady agricultural demand across every market we track, with the pace of the gains picking up somewhat in the most recent two quarters. That kind of steady, uninterrupted climb is worth noting, since it stands in contrast to how choppy some other commodities in this space have looked over the same period.

What was Magnesium Sulfate Price in 2025?

2025 was a steady year for magnesium sulfate. Starting near USD 350/MT in Q1, the global average finished 2025 at USD 362, a gain of about 3.4%. The agricultural and pharmaceutical demand held consistent all year across every market we track, before the pace of gains picked up further once 2026 got underway. The consistency of that pattern across all four regions makes this one of the more predictable agricultural-chemical markets we track. Buyers who track this market closely tend to view that steady annual pattern as the baseline against which any future quarter's move should be judged.
