Sulphur prices in the United States softened in late February as ample import availability, stable refinery output, and smooth logistics kept supply comfortable. Early in the month, market activity remained largely stable, but sentiment weakened toward the end of February as sellers relied on inventories to meet cautious buying interest. Downstream demand remained subdued, with most buyers adopting a wait-and-see approach, although limited safety-stock replenishment provided some support. Weekly assessments showed prices trending higher early in the month before easing later, with values falling 3.2% in the final week of February to USD 516/MT. Despite the recent decline, the market outlook has turned more uncertain due to rising geopolitical tensions in the Middle East. The announced closure of the Strait of Hormuz by Iran’s Islamic Revolutionary Guard Corps threatens a key route for global sulphur exports, potentially tightening supply and driving prices higher in the coming weeks.
Sulphur prices in the USA turned lower in late February as ample import availability and eased logistics weighed on the market. Early and mid-month trading showed calm conditions with minimal movement, but the balance shifted in the latter part of the month when sellers leaned on inventories to meet cautious buying. Downstream procurement remained muted overall, though isolated safety-stock replenishment provided sporadic support. The net effect was a clear short-term softening of sentiment heading into the final trading days of February, setting the scene for range-bound activity unless a surprise tender or logistics issue emerges.
Sulphur demand patterns were mixed across end-users. Downstream users largely maintained a cautious procurement stance, described as soft, while a handful of end-users replenished safety stocks and provided marginal support.
Supply dynamics pressured the Sulphur market as logistics and inventory factors kept delivered costs contained. Inventories remained comfortably above immediate consumption needs and vessel space was reported as easy, allowing sellers to offer material more aggressively. Domestic refinery runs were undisrupted through the period and complemented import arrivals rather than absorbing them. Those conditions helped temper any upward Sulphur price momentum even as some buyers topped up buffers. The February assessment reflecting competing forces between cautious demand and ample supply.
Weekly Sulphur price movement accelerated the late-month softening. Prices trended higher through early February before stabilizing mid-month and then slipping in the final weeks, per weekly assessment data, the last week of February 2026 saw a notable decline of 3.2% as levels moved to USD 516.00/MT. The price of Sulphur highlighting that the late-February drop followed a period of cooling from the mid-month peak. Overall, weekly flows point to increased selling pressure as logistical ease and import availability intersected with cautious buying.
As per ChemAnalyst, however, the recent escalation in tensions between the United States and Iran has created a significant bullish outlook for global sulphur prices in the coming weeks. Iran’s Islamic Revolutionary Guard Corps announced the closure of the Strait of Hormuz on February 28, prompting multiple tanker owners and traders to suspend transit through the route. As the Strait functions as the primary artery for Middle Eastern sulphur exports, the disruption threatens roughly half of global seaborne sulphur trade, equivalent to around 20 million tonnes annually. Major exporting countries, including Saudi Arabia, United Arab Emirates, Qatar, Kuwait and Iran rely on the passage to ship sulphur to global markets, including the United States.
With key export terminals effectively blocked and alternative routes offering limited capacity and higher logistical costs, supply tightness is likely to intensify in the near term. Consequently, traders are expected to bid up spot prices as inventories tighten and freight costs rise. Unless maritime flows through the Strait resume quickly, sulphur prices could experience sharp upward volatility over the next several weeks.
