India Halts All Sulfur Exports as Supply Crisis Bites

India imposed a comprehensive ban on sulfur exports on July 16, 2026, suspending overseas sales across all product categories nationwide. According to feedback from Indian refineries, national authorities issued a directive instructing producers and traders to prioritize domestic supply and safeguard local availability. The order requires local refineries and traders to stop signing new sulfur sales contracts and to halt outbound shipments, with all sulfur resources inside the country folded into a coordinated domestic allocation system.

The decision follows repeated appeals from Indian industry groups, which had pressed New Delhi for months to protect domestic feedstock. India consumes roughly 2 million tonnes of sulfur each year, and more than half of that demand is covered by imports, with close to half of those imports arriving from the Middle East. The immediate trigger for the ban was the sustained disruption to shipping through the Strait of Hormuz, where Middle East conflict has choked seaborne sulfur flows since late February 2026 and steadily tightened global supply.

India's export ban lands hardest on China. Trade data for 2024 show that India shipped about 805,000 tonnes of crude sulfur abroad, worth roughly 81 million US dollars, and close to 99 percent of that volume, around 797,000 tonnes, went to Chinese buyers. Smaller quantities reached Tanzania, South Africa, Sri Lanka, and Australia. With this channel now closed, Chinese importers have lost a significant supplementary source at a moment when other routes are already constrained.

The market reacted quickly. Chinese domestic sulfur spot prices moved higher as expectations of shrinking overseas supply spread through the trade. Several petrochemical producers in Shandong raised their ex-factory quotations on July 15, one day before the Indian ban took effect, and port prices climbed in step.

India's move is the latest in a series of sulfur export controls that have accumulated through 2026. China announced a full ban on sulfuric acid exports in April, effective from May through August. Russia's sulfur export ban took effect on July 1 and now runs through December 31, with exemptions limited to the Eurasian Economic Union. Kazakhstan suspended sulfur exports in late June, and Turkey has restricted shipments since April. Together these measures have removed multiple layers of flexible supply from the market at the same time.

Because sulfur underpins phosphate and sulfate fertilizers as well as copper, nickel, and other industrial processes, the tightening is expected to keep pushing input costs higher across agriculture and metals. Fertilizer producers in South Asia and beyond face rising costs for products such as single super phosphate and ammonium sulphate. In the short term, with India's ban compounding Middle East supply disruptions, market participants expect global sulfur availability to remain strained and prices to stay under upward pressure.
