Fertilizer Sector Faces Double Whammy: China Ban and Iran Conflict Stoke Cost Inflation Fears

Fertilizer Sector Faces Double Whammy: China Ban and Iran Conflict Stoke Cost Inflation Fears​

Fertilizer stocks, including major players like Coromandel International, Paradeep Phosphates, Chambal Fertilisers, GSFC, RCF, and FACT, are under intense scrutiny. The sector is navigating a significant supply shock driven by simultaneous global disruptions. These concerns center on China curbing sulphuric acid exports and geopolitical tensions compounding the raw material crunch.

The double blow threatens to drastically inflate input costs for Indian manufacturers. The industry faces a confluence of factors, including escalating global commodity prices and constrained supply chains.

Sulphuric Acid and Sulphur Supply Shock Threatens Fertilizer Inputs​

China's decision to restrict exports of sulphuric acid, particularly the by-product derived from copper and zinc smelting, signals a major pivot. This move indicates a shift towards domestic prioritization for China, especially ahead of its peak crop planting season.

This restriction is poised to tighten the global availability of sulphuric acid, which is a key industrial chemical. The market is already grappling with constraints exacerbated by geopolitical instability.

The situation is made substantially worse by disruptions in the sulphur supply linked to the Iran conflict. The effective closure of the Strait of Hormuz has severely choked critical shipments from the Middle East. This region is responsible for supplying nearly one-third of the global sulphur production, creating a critical raw material shortfall.

Impact of Input Cost Inflation on Indian Manufacturers​

Sulphuric acid plays a vital role not only in phosphate fertilizer production but is also widely used in metal extraction, such as copper refining. Any sustained increase in its price structure poses an immediate challenge to fertilizer manufacturers.

For India, the rising input costs present a margin squeeze risk. While the nation relies on these chemicals, India imported approximately $118 million worth of sulphuric acid in 2024, underscoring its dependence on global markets.

Analyst viewpoints suggest that sustained supply crunch could translate directly into higher working capital requirements and increased earnings pressure for domestic firms. These challenges are compounded by potential regulatory constraints that may limit the ability to fully pass on price increases to farmers.

Broader Economic Risks Beyond Fertilisers​

The supply squeeze is not limited to fertilizers. Since sulphur is the fundamental precursor to sulphuric acid, the raw material shock impacts various industrial sectors.

Furthermore, the disruption is expected to ripple out, impacting copper producers globally. This includes key mining regions such as Chile, the Democratic Republic of Congo, and Zambia, which are reliant on stable input supplies.

The collective pressure points highlight a macro environment where logistical challenges and supply-side shocks are becoming the dominant risk factors for the industrial economy.
