Sulphur production continues to expand in the Middle East and East and South Asia both from new refineries and major sour gas projects.

Policy decisions and geopolitical shocks are now the dominant drivers of sulphur and phosphate fertilizer markets, overriding more traditional seasonal fundamentals. The conflict in the Middle East, including the escalation around Iran, has tightened sulphur availability and lifted costs sharply, while China’s export restrictions continue to restrict global phosphate supply.

Canada-based Ivanhoe Mines stands to benefit from any sulphuric acid shortage caused by prolonged closure of the Strait of Hormuz now that the company is running a copper smelter, according Co-Chairman Robert Friedland. The 500,000 t/a direct-to-blister smelter at company-operated Kamoa-Kakula mine in the Democratic Republic of Congo produced its first anodes at the turn of the year.

The Zambian government has introduced a new permit system to manage the export of sulphuric acid, which came into effect on 27 March, 2026, according to an announcement from the Ministry of Commerce, Trade and Industry. The move comes at a time of significant exceptionally high prices and sourcing challenges in the global sulphur market, adding another layer of tightness for regional consumers. The Ministry stated that the measure is designed to correct a "critical market imbalance" and ensure supply for the country's domestic industries. The system aims to safeguard local downstream sectors that rely on the acid, while still ensuring that the needs of the export market are met, it said.

Several battery material nickel miners in Indonesia have reportedly trimmed output by at least 10% due to a shortage of and higher prices for sulphur caused by supply disruptions arising from war in the Middle East. Sulphuric acid is used to process nickel ore into mixed hydroxide precipitate (MHP), a feedstock used in electric vehicle (EV) batteries.

Topsoe has entered into an agreement with Texas-based sustainable fuels and chemicals technology company BioVeritas to unlock advantaged feedstocks for existing infrastructure. The agreement will enable fuel producers to license Topsoe’s HydroFlex® technology alongside the Bio-Veritas Process™ to produce renewable fuels from second-generation feedstocks, such as woody biomass, corn stover, wheat straw, and similar waste and residual biomass. The BioVeritas Process™ converts second-generation feedstocks to advantaged intermediates, called KEY-Tones™ that can be processed by Topsoe’s HydroFlex® technology to unlock production of renewable fuels using second-generation feedstock.

It is two months on from our previous issue, and almost none of the news has been good from sulphur and downstream markets. Only three sulphur cargoes are confirmed to have transited the Strait of Hormuz since the US and Israeli strikes on Iran began, all loaded at Ruwais, with destinations in India, Tanzania and Morocco, carrying a total of 160,000 tonnes. It is believed that a couple of Iranian vessels with a total of 75,000 tonnes may also have left covertly. But in spite of some Middle Eastern sulphur making its way to Saudi Red Sea ports or Duqm on Oman’s Indian Ocean coast, around 700,000 tonnes is still trapped on ships stranded in the Gulf, and coupled with production cuts in the region, it is estimated that over 1.2 million tonnes has so far been removed from the market.

Sour gas production is costly because hydrogen sulphide and carbon dioxide require extensive sweetening, sulphur recovery, safety, and compliance infrastructure, with sulphur sales helping offset but rarely eliminating those added costs.

InfraLeuna GmbH, the owner and operator of the Leuna chemical site, has unveiled a new state-of-the-art heating terminal as part of a new central infrastructure facility established at the Leuna chemical site to address the changing demands of the chemical industry’s supply chains.

• Prices are expected to hold at historically high levels as long as the Strait of Hormuz remains effectively closed. If the situation persists, further price increases are likely, which will only intensify the affordability crisis for global consumers.
