Nickel producers in Indonesia reduce battery feed production as the sulphur squeeze bites

Three sources said that a sulphur scarcity, caused by the Iran War, forced nickel processors in Indonesia to reduce their output?by 10% or more since last month.

The cutbacks?have?hit plants using sulphuric acids to process nickel ore, a feedstock for electric vehicle batteries, into mixed hydroxide precipate (MHP), one of the most clear signs yet that U.S. and Israeli war against Iran is affecting mining supply chains. However, output remains relatively high.

Sources said that affected plants include those owned by Chinese companies such as Huayou Cobalt and Lygend Resources, as well Tsingshan Group.

Requests for comment were not immediately answered by the companies.

Sources said that several plants were operating above their capacity due to high margins and a large demand. The curbs have now lowered the output to the nameplate level. This means that Indonesia's nickel production is still high but MHP supplies are tightening.

The Middle East is a major supplier of SULFUR

According to Arif Perdana 'Kusuma', the chairman of FINI (Indonesia's nickel smelters' association), about a quarter or more of the world's sulphur is supplied by Middle East. These disruptions have pushed prices up and squeezed margins for Indonesian MHP producers, leading to the production cutbacks.

One trader reported that spot sulphur prices delivered to Indonesia had risen to over $800 per metric ton. Some cargoes were sold for as much as $1,000, compared to around $500 prior to the start of the war.

Sources declined to name themselves as they weren't authorised to talk to the media.

In Search of Alternatives

Kusuma stated that no nickel refineries using high-pressure acid lach (HPAL) had been forced by the sulphur shortages to stop MHP production, but stocks at several firms are running low.

He said that in some places, the current stocks would only last until May or even earlier. However, he did not say whether plants had reduced production.

Some producers are now looking for alternative sources of sulphur, but this is difficult due to the smaller volumes and longer shipping distances. Some producers were importing sulphuric acids instead. This poses logistical challenges and requires import permits.

He said that HPAL's operating costs now account for between 30% and 35% sulphur, up from the usual 25%.

Reports last month indicated that some Indonesian factories had inventory?lasting just one to two months. Production cuts are likely in April if the supply does not recover.

Indonesia's nickel industry is struggling with higher ore costs after Jakarta restricted mining output. Indonesia announced that nickel mining quotas for 2026 would be reduced from 379 millions to 250 million wet metric tons.

The nickel ore price is expected to increase after Indonesia changed the formula for calculating tax, royalties, and other charges on nickel ore sales. This new formula will be implemented in April and put further pressure on producers' margins.
