Market Outlook

Market Outlook

SULPHUR

• The global sulphur market is forecast to enter a downward trend as supply from Saudi Arabia normalises following the summer months, while demand decreases alongside demand for phosphate fertilizers. The price is expected to fall towards the end of the year, with a low of around $220/t by May 2026.

• Prices in Canada are expected to follow a similar trend driven by demand in Asia. The forecast sees this downward trend holding until April 2026 at a level close to $210/t f.o.b.

• In China, sulphur prices have been increasing domestically as the announcement of a second round of phosphate export quotas alongside requirements for the autumn application season were met with volumes that had been purchased previously at higher price levels. Offers of imports into the country have also been increasing and the forecast now expects the price to average $315/t c.fr during September but decreasing towards November as demand becomes subdued with most requirements for the Autumn application season met.

• Brazil has seen limited activity and has as of late purchased predominantly US Gulf material. The latest CMOC tender is understood to have received a reduced number of offers of FSU material due to the limited availability in that region. With this supply limitation anticipated to continue, it is likely that prices will increase.

SULPHURIC ACID

• Prices in the global sulphuric acid market are expected to decrease further in the coming weeks. Demand is likely to remain opportunistic leading to a market of overall limited transactions. The outlook forecasts that prices in both Europe and Chile will trend downwards and expected to decrease from September through April 2026, possibly as low as $60/t by early 2026.

• European volumes are being offered across delivered markets amid subdued demand but uncertainty regarding a potential return of a buyer in Morocco for Q4 has proven sufficient to limit the pace of the fall this month. We also expect the number of transactions to be relatively limited through September before the downward trend is cemented as Q4 steps in.

• Purchases in Chile over the last two months have been limited despite firm offers for material in the market, as sufficient inventory levels capped need for spot tonnes. With negotiations for annual contracts soon to kick off, the market is likely to limit spot purchases through September.

• The domestic sulphuric acid market in China has stabilised on healthy availability. As a result, some material has been introduced to the export market, which has helped cover some of the supply missing from Japan/South Korea. Offers of Chinese material were heard in the $80s/t even high $70s/t f.o.b., but current time frames see material available for October loading.

CIMC Enric commissions biomethanol project

CIMC Enric Holdings Ltd says that it has commissioned China’s first large-scale biomethanol facility in Zhanjiang, Guangdong Province, marking a major step forward in the decarbonisation of global shipping and clean fuel supply chains. The project, developed by CIMC Enric and its subsidiaries, is designed as a fully integrated closed-loop system converting forestry residues into green methanol for use as marine fuel. With an initial annual capacity of 50,000 t/a, it is the country’s first commercial scale green methanol plant, and is backed by the port of Zhanjiang and abundant local forestry wastes.

World’s largest integrated green hydrogen-ammonia-methanol project

The first 320 MW phase of what China Energy Engineering Corporation Ltd says will ultimately become the world’s largest integrated green hydrogen-ammonia-methanol project HyFlow has officially begun operation in Songyuan City in Jilin Province. With a total investment of nearly $4.30 billion, the Songyuan project uses a “wind-solarhydrogen-ammonia-methanol” integration model, creating an industrial chain that includes hydrogen production and storage, as well as hydrogen-derived chemicals such as ammonia and methanol, hydrogen energy equipment, and scientific research. The project eventually plans to develop 3 GW of renewable energy capacity from wind and solar power, alongside a target production capacity of 800,000 t/a of green ammonia and methanol. The annual production of green hydrogen in the project’s first phase is expected to be equivalent to approximately one-fifth of China’s current total annual green hydrogen production.
