Sulphur 420 Sep-Oct 2025

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.

Desulphurisation unit installed at Luján refinery

YPF says that its modernisation of the Luján de Cuyo refinery has taken a step forward with the installation of a hydrodesulphurisation reactor, designed to remove sulphur compounds from diesel fuel by means of a catalytic process using hydrogen. The installation forms part of the refinery’s New Fuel Specifications (NEC) project, intended to produce of fuels with a lower environmental impact. The new reactor was built in Mendoza by IMPSA. With a length of 38 meters and a weight of 456 tons, it was moved from Godoy Cruz to the YPF plant in a logistic operation that involved Vialidad Nacional, Mendoza Police and local authorities. It will now be integrated into the HDS II unit, designed to reduce sulphur content in diesel to 10 parts per million, in line with current environmental requirements. The NEC plan includes new process units, such as H2 II and SE33, the adaptation of existing facilities and the improvement of auxiliary services. The project, already 85% complete, will allow all the diesel oil produced in Luján de Cuyo to comply with the highest emission requirements.
