A technical glitch has forced the closure of Yara Pilbara, Australia’s largest producer of ammonia, a critical input for urea fertilizer and mining explosives, for at least two months. The shutdown, which began this week, disrupts a key supply chain at a time when global ammonia trade is already strained by geopolitical conflicts.
The outage at the Pilbara facility, located in Western Australia, stems from a power outage that damaged critical systems, although specifics were not provided. Yara, a global leader in fertilizer production, has confirmed that repairs and safety checks will keep the plant offline until at least late May 2026. This closure impacts not only agricultural sectors reliant on urea for crop production but also mining operations in Australia that depend on ammonia for explosives.
The plant last year produced 850,000 tonnes of ammonia, while the second largest in the country, found near Perth, produced only 255,000 tonnes last year.
Compounding the issue roughly 25% of the world’s ammonia trade, and 43% of urea, is currently blocked due to the ongoing Iran war which has blocked the Strait of Hormuz. With global supplies already tight, the loss of Yara Pilbara’s output could drive up costs for farmers and miners alike.
Australian authorities and industry stakeholders are scrambling to secure alternative supplies, though options are limited amid international shortages. The timing of the shutdown adds pressure to an already volatile commodity market, where fertiliser prices have spiked in recent years due to supply chain disruptions and rising energy costs.
Yara has pledged to expedite repairs, targeting a restart by the end of May 2026. Until then, the economic fallout from this two-month hiatus is expected to reverberate across Australia’s agricultural and mining sectors, with potential cost increases looming for end users.
