Oleum prices in Germany, the highest-cost reporting region, rose 4.4% in Q2 2026 to USD 355.00/MT from USD 340.00/MT in Q1, extending a sharp climb tied to elevated sulfur and sulfuric acid feedstock costs. Globally, the average rose from USD 281.50/MT in Q1 to USD 295.36/MT in Q2, a 4.9% gain, following a jump of 13.3% in Q1 alone as the broader Middle East-linked energy market disruption pushed sulfur costs sharply higher. For H2 2026, a global average of USD 260.00-360.00/MT is expected, with elevated sulfur feedstock costs likely to keep this market firm.
Oleum, also known as fuming sulfuric acid, is a solution of sulfur trioxide dissolved in concentrated sulfuric acid, produced by absorbing additional sulfur trioxide gas into the sulfuric acid stream during the contact process. It serves as a critical intermediate in detergent and surfactant manufacturing, dye and pigment production, explosives manufacturing, and specialty chemical synthesis where its stronger sulfonating power exceeds that of standard concentrated sulfuric acid. Because sulfur trioxide is derived from elemental sulfur, itself largely a byproduct of crude oil and natural gas refining, this market's cost structure tracks the broader sulfur and sulfuric acid value chain closely, making it directly exposed to the same energy market disruptions that have affected related chlor-alkali and petrochemical intermediates. Sulfur and sulfuric acid feedstock costs, detergent and surfactant demand, and energy costs for sulfur trioxide production are what drive prices in this market.
The outlook for Oleum through H2 2026 stays firm, tracking elevated sulfur and sulfuric acid feedstock costs tied to the broader Strait of Hormuz-linked energy market disruption. Steady demand from detergent, surfactant, and dye manufacturers should continue supporting consumption, even as the pace of further gains likely moderates from the sharp Q1 2026 spike that characterized every region covered here.
The main upside risk is a further tightening of sulfur or sulfuric acid feedstock availability, which would push production costs higher across every region. The main downside risk is a faster-than-expected normalization of energy costs combined with softer detergent and surfactant demand, which would ease some of the current price pressure.

Chinese prices, the lowest of the four regions, averaged USD 232.00/MT in Q2 2026, up 5.5% from USD 220.00/MT in Q1, as large-scale domestic production capacity continued absorbing elevated feedstock costs.
Why did the price of Oleum change in Q2 2026 in China?
Large-scale domestic production capacity continued keeping Chinese offers the most competitive of any region tracked here, even as the broader sulfur feedstock cost environment pushed prices modestly higher.
German prices surged 13.3% in Q1 2026 to USD 340.00/MT from USD 300.00/MT in Q4 2025, as sulfur and sulfuric acid feedstock costs spiked following the broader Middle East-linked energy market disruption.
Why did the price of Oleum change in Q1 2026 in Germany?
Sulfur and sulfuric acid prices surged sharply as the global feedstock repricing following Middle East escalation raised the cost basis across the entire sulfonation value chain, and that pressure flowed directly through to finished oleum pricing across German detergent and dye supply chains.
US prices surged 13.5% in Q1 2026 to USD 295.00/MT from USD 260.00/MT in Q4 2025, tracking the broader global feedstock cost spike.
Why did the price of Oleum change in Q1 2026 in the United States?
Elevated sulfur and sulfuric acid feedstock costs, tied to the Middle East-linked energy market disruption, pushed US production expenses sharply higher, even as steady underlying detergent and surfactant demand kept this market fundamentally well supported.
Indian prices surged 13.3% in Q1 2026 to USD 255.00/MT from USD 225.00/MT in Q4 2025, tracking the broader Asian feedstock cost spike.
Why did the price of Oleum change in Q1 2026 in India?
Elevated crude oil and natural gas prices, following disruptions to global energy markets tied to the Middle East conflict, increased production costs for sulfur trioxide feedstock, pushing Indian oleum prices higher through the quarter.
Chinese prices surged 12.8% in Q1 2026 to USD 220.00/MT from USD 195.00/MT in Q4 2025, tracking the global sulfur feedstock cost spike even as domestic production capacity remained substantial.
Why did the price of Oleum change in Q1 2026 in China?
Rising sulfur and sulfuric acid feedstock costs, tied to the broader Middle East-linked petrochemical cost environment, fed through to Chinese oleum pricing even as the country's substantial domestic production capacity kept the pace of the increase comparatively moderate.
Global Oleum prices eased gradually through most of 2025 as sulfur feedstock costs moderated, before accelerating sharply in Q1 2026 as rising sulfur and sulfuric acid feedstock costs, tied to the broader Middle East-linked energy market disruption, pushed prices to their highest levels of the period, a trend that continued into Q2 across every region tracked in this report.
