Yara Pilbara Ammonia Plant Shutdown in Australia - March 2026

Australia's largest ammonia production facility, operated by Yara International on the Burrup Peninsula in Western Australia, has been forced into an unplanned two-month shutdown following a power outage that caused significant equipment damage. The incident occurred in mid-March 2026 at the Yara Pilbara Fertilisers plant near Karratha, a facility that produces approximately 850,000 tonnes of ammonia annually and accounts for roughly 5% of global traded ammonia supply.

Yara confirmed that no workers were injured and that there was no environmental contamination resulting from the power failure. However, the damage to critical plant systems was severe enough to require an estimated two months of repairs, with operations not expected to resume until late May 2026 at the earliest. The Norwegian company stated that it understood the importance of its products to customers and would prioritize restoring operations as quickly as possible.

The timing of this shutdown is particularly damaging for multiple sectors of the Australian economy. The plant supplies 140,000 tonnes of ammonia per year to an adjacent technical ammonium nitrate (TAN) facility, a joint venture between Yara and Orica, which has the capacity to produce up to 400,000 tonnes of TAN annually. This explosive material is essential for blasting operations in Western Australia's iron ore mining sector, the country's most valuable export industry. With the plant offline, miners in the Pilbara will lose access to approximately 330,000 tonnes per year of locally produced TAN. The extent of disruption to mining operations will depend on existing stockpiles and the ability to source alternative supplies at short notice.

Australian agriculture faces equally serious consequences. The country imported 1.2 million tonnes of urea during April and May 2025 in preparation for seeding, with three-quarters of those imports sourced from Gulf nations. That supply route is now severely constrained following the military conflict between the United States, Israel, and Iran, which has effectively closed the Strait of Hormuz to commercial shipping. More than 25% of global ammonia trade and 43% of urea shipments normally transit through this chokepoint. The conflict has also disrupted natural gas supplies to the region, forcing fertiliser plants in India to shut down production.

Yara itself has been affected on multiple fronts by the broader crisis. The company reduced ammonia and urea production at its Babrala plant in Uttar Pradesh, India, due to gas supply shortages caused by the Middle East conflict. Several other fertiliser producers in India and the Gulf region have also curtailed or halted operations.

The only other major ammonia producer in Western Australia is CSBP, a subsidiary of Wesfarmers, which operates a plant in Kwinana near Perth with an annual output of 255,000 tonnes. CSBP also imports additional ammonia to manufacture ammonium nitrate for both fertiliser and explosives markets. The company declined to confirm whether any of its imported ammonia came from Yara, stating only that it continually monitors and manages its supply chain to meet customer demand.

This incident adds to a growing list of supply chain vulnerabilities affecting the global ammonia and fertiliser markets. The closure of the Strait of Hormuz has already removed a quarter of traded ammonia volumes from the market. Yara's own production curtailments in India compound the supply deficit further. In Europe, the company has also faced headwinds from high energy costs and regulatory uncertainty around the Carbon Border Adjustment Mechanism (CBAM). Meanwhile, ammonia prices have been rising sharply, with US anhydrous ammonia averaging around $895 per ton in early March 2026 and urea prices increasing by 5% month over month to $625 per ton.

The Yara Pilbara plant began production in April 2006 and ships ammonia from the Port of Dampier to customers in Australia and across the Asia-Pacific region, including Taiwan, Thailand, South Korea, and Japan. The facility has also been positioned as a future hub for clean energy, with the adjacent Project Yuri renewable hydrogen plant designed to feed green hydrogen into ammonia production. However, the current shutdown puts any near-term clean ammonia ambitions on hold.

For Australian farmers preparing for the 2026 growing season, the combination of a domestic production shutdown and restricted imports from the Middle East creates a potentially severe fertiliser supply crisis. For the mining industry, the loss of local TAN supply could slow iron ore extraction if alternative sources cannot be secured quickly enough. The broader global fertiliser market, already under pressure from geopolitical disruption and rising energy costs, faces additional strain from the removal of one of the world's largest ammonia plants from the supply picture for at least two months.
