A global sulfur shortage and sharp price surge have driven up the prices of sulfur-based industrial gases, including sulfur dioxide (SO₂) and sulfur hexafluoride (SF₆), which are essential materials for the chemical, electronics and manufacturing industries.
The global sulfur market has experienced an unprecedented price surge in 2026, driven by intensified geopolitical tensions in the Middle East, disrupted maritime transportation via the Strait of Hormuz, and persistently low port inventories worldwide. month-on-month increase and hitting a decade-high record.Global sulfur prices have hit a decade-high in 2026, fueled by Middle East geopolitical tensions, disrupted maritime transport and ultra-low port inventories. Since February, international sulfur prices have jumped over 119%.
As an essential raw material for producing high-purity industrial gases, sulfur’s dramatic price inflation has directly squeezed the profit margins of gas manufacturers and triggered synchronous price increases for derivative gas products. Sulfur dioxide (SO₂), primarily produced through sulfur combustion and oxidation, relies heavily on elemental sulfur as its core feedstock. The tight sulfur supply has forced SO₂ production enterprises to cut operating loads due to rising raw material costs and insufficient raw material supplies, resulting in reduced market supply SO₂. The uptrend is set to continue.
Similarly, sulfur hexafluoride (SF₆), a high-value special industrial gas indispensable in power equipment, semiconductor manufacturing, and high-voltage electrical insulation, has also faced obvious cost pressure. The production of SF₆ requires high-purity sulfur as a key raw material for fluorination synthesis. The continuous surge in sulfur prices, coupled with tight global raw material circulation, has led to a notable increase in SF₆ production costs.
The current sulfur supply crisis is difficult to ease in the short term. China’s sulfur import dependence exceeds 49%, with over half of imported sulfur sourced from the Middle East. The ongoing regional conflicts continue to hindr maritime logistics, keeping global sulfur inventories at historically low levels—some major domestic ports only maintain inventories sufficient for less than one month of normal production. Sulfur price will remain high and volatile in the next one to three months, and the cost pressure will continue to transmit downstream.
Against this backdrop, SO₂ and SF₆ prices will remain on an upward track, bringing notable cost pressures to downstream power, electronics and chemical industries.
