“South Africa’s sulphur imports plunged by 68% in early 2026 due to Middle East supply disruptions linked to the US-Iran conflict, leaving industries scrambling for alternatives. The shortages have forced fertilizer producer Foskor and Sasol to halt operations, tightening acid availability and threatening agricultural and mining output.”
South Africa’s trade and industrial sectors are facing a crisis as sulphur imports, a critical input for fertilizer and sulphuric acid production, have collapsed by nearly 70% in the first half of 2026. This sudden disruption has exposed the fragility of the country’s supply chains, with ripple effects across agriculture, mining, and manufacturing. The crisis underscores how geopolitical tensions and logistical bottlenecks can destabilize domestic industries reliant on imported raw materials.
The Collapse in Imports
Between January and May 2026, South Africa imported only 56,300 tonnes of sulphur, compared to 174,183 tonnes in the same period of 2025. The decline was driven by the absence of Middle East cargoes, traditionally the backbone of South Africa’s sulphur supply. In 2025, imports from Kuwait, Oman, Saudi Arabia, and the UAE collectively accounted for over 170,000 tonnes. This year, only one shipment of about 55,000 tonnes arrived in February, before supplies dried up completely.
The disruption stems from the US-Iran conflict, which escalated in late February and disrupted Gulf shipping routes. South African buyers, heavily dependent on Middle East producers, were left scrambling for alternative sources.
Impact on Domestic Industries
The consequences have been immediate and severe:
- Fertilizer production: Foskor, South Africa’s leading fertilizer and sulphuric acid producer, shut down operations in March due to shortages. This has left farmers without critical inputs during planting season, threatening food security.
- Mining sector: Copperbelt mining companies in neighboring countries secured premium-priced sulphur from alternative suppliers, leaving South African buyers at a disadvantage.
- Chemicals and pulp industries: Reduced operating rates have been reported, as sulphur is essential in multiple industrial processes.
Sasol, another major sulphur and sulphuric acid producer, suffered an unplanned shutdown in March, further tightening supply. The company is expected to remain offline until August, exacerbating shortages.
Logistics and Cost Pressures
The crisis has been compounded by soaring logistics costs. Diesel price hikes in March and April pushed trucking rates to unprecedented levels:
- $1,000 per tonne for round trips between Richards Bay and the DRC.
- $600 per tonne for routes to Kolwezi, reducing competitiveness compared to Tanzanian backhaul options.
These costs have eroded margins for South African firms, making imports less viable and further straining supply chains.
Agricultural Fallout
The agricultural sector, already battling climate volatility and rising input costs, is particularly vulnerable. Fertilizer shortages threaten crop yields, while higher prices squeeze farmers’ profitability. With El Niño conditions forecast to intensify drought risks in 2026/27, reduced fertilizer availability could compound food insecurity.
Strategic Trade Implications
South Africa’s reliance on Middle East sulphur highlights a broader vulnerability in its trade strategy. The crisis raises urgent questions:
- Should South Africa diversify its import sources to reduce dependence on geopolitically unstable regions?
- Can domestic production capacity be expanded to buffer against external shocks?
- How can logistics bottlenecks at ports and trucking routes be alleviated to reduce costs?
Government and Industry Response
The government has yet to announce a comprehensive response, but industry leaders are calling for:
- Emergency stockpiling of critical inputs.
- Diversification of suppliers, including exploring African and Asian markets.
- Investment in domestic refining capacity to reduce reliance on imports.
Conclusion
South Africa’s sulphur import collapse is more than a temporary disruption—it is a wake-up call for the country’s trade and industrial policy. Without decisive action, the shortages could undermine agricultural productivity, mining competitiveness, and broader economic stability. The crisis illustrates the interconnectedness of global trade and the risks of over-reliance on single supply regions.
