France Calls for Suspension of EU Carbon Border Levy on Fertilisers as Iran War Tightens Global Supply

France’s push to suspend the EU’s carbon border levy on fertilisers comes as the war in Iran disrupts key shipping routes and drives up fertiliser and energy costs worldwide. Any temporary relief from the Carbon Border Adjustment Mechanism (CBAM) would ease input costs for EU farmers but could reshape fertiliser trade flows and pricing dynamics across nitrogen and phosphate markets.

The move, led by French Agriculture Minister Annie Genevard, targets CBAM charges on imported fertilisers at a moment when the closure of the Strait of Hormuz has choked fertiliser and LNG traffic and triggered sharp price spikes. EU institutions, however, remain reluctant to weaken CBAM, arguing that suspending the levy could increase dependence on high‑carbon imports and undermine domestic producers’ competitiveness.

Introduction

At a meeting of EU agriculture ministers in Brussels on Monday, France and several allies formally asked the European Commission to suspend CBAM charges on fertiliser imports for the duration of the Iran conflict. The appeal comes amid mounting protests from farmers over soaring fuel, gas and fertiliser costs linked to the US–Israel war with Iran and the partial closure of Hormuz, a critical corridor for fertiliser and energy exports.

The Commission reiterated its concerns that lifting CBAM on fertilisers could exacerbate reliance on external suppliers just as the region seeks to reduce its exposure to geopolitical shocks. EU officials instead highlighted ongoing work on a broader fertiliser action package and the possibility—still under negotiation—of narrowly framed, time‑bound derogations, including retroactive options from 1 January 2026.

🌍 Immediate Market Impact

The policy debate is unfolding against a backdrop of rapidly tightening global fertiliser balances. UN and FAO officials report that tanker traffic through the Strait of Hormuz—through which roughly a third of global fertiliser trade passes—has plunged by more than 90%, disrupting supplies of urea and other nitrogen products and pushing up freight and product prices.

In Europe, higher fertiliser costs are already feeding into grain market sentiment, with Euronext wheat drifting as traders reassess yield and planting risks tied to elevated input costs. Analysts warn that sustained price spikes could lead farmers to trim nitrogen application rates or shift cropping patterns, potentially tightening supplies of wheat, corn and oilseeds in the next marketing year.

📦 Supply Chain Disruptions

The conflict in Iran has sharply disrupted maritime logistics. The near‑shutdown of Hormuz has stalled cargoes of urea, ammonia and mixed fertilisers from Gulf producers, who are also grappling with damage to regional energy infrastructure. This is lengthening lead times and forcing importers to seek alternative origins at higher cost.

For the EU, logistics stress is compounded by CBAM: importers of fertilisers from non‑EU suppliers must factor in embedded emissions costs in addition to elevated freight and feedstock prices. While the Commission is exploring tariff suspensions on certain fertiliser inputs such as ammonia and urea, CBAM liabilities remain in place, potentially amplifying landed cost inflation and narrowing sourcing options for blenders and distributors.

📊 Commodities Potentially Affected

• Nitrogen fertilisers (urea, ammonium nitrate, UAN) – Directly hit by disrupted Gulf exports, higher LNG prices and CBAM‑linked import costs into the EU, leading to higher farmgate input prices and margin pressure.
• Phosphate and potash fertilisers – Less concentrated in Hormuz flows but affected by higher freight rates, shifting trade routes and potential substitution as buyers rebalance nutrient sourcing.
• Wheat and coarse grains (corn, barley) – Highly sensitive to nitrogen application; prolonged input cost inflation could curb application rates, restrain yields and tighten exportable surpluses.
• Oilseeds (rapeseed, soybean, sunflower) – Facing indirect pressure through higher fertiliser and fuel costs, with potential acreage and intensity shifts in the EU and other importing regions.
• Natural gas and LNG – Central feedstock for nitrogen fertiliser production; damage to Gulf energy capacity and constrained flows are lifting global gas benchmarks and production costs.

🌎 Regional Trade Implications

If CBAM remains fully applied to fertilisers, EU buyers may prioritise imports from lower‑emission producers able to minimise CBAM exposure, potentially favouring select North African and intra‑EU suppliers over higher‑emission origins. This could redirect trade flows away from some Gulf and Black Sea exporters, at least while Hormuz disruptions persist.

Conversely, a temporary CBAM suspension on fertilisers—if agreed—would likely reopen the door to more price‑competitive third‑country imports, easing margins for EU farmers but weighing on domestic fertiliser producers. Developing import‑dependent regions in Africa and Asia, already facing tighter fertiliser availability and higher prices, could face fiercer competition for spot cargoes if EU demand rebounds.

🧭 Market Outlook

In the near term, fertiliser markets are set for continued volatility as traders weigh three moving parts: conflict risk and shipping access in the Gulf, EU policy decisions on CBAM and tariffs, and potential demand rationing at the farm level. Any concrete signal from Brussels on temporary CBAM exemptions for fertilisers could trigger swift price adjustments for EU‑delivered product and related futures curves.

Beyond the immediate crisis, market participants will monitor the EU’s forthcoming Fertiliser Action Plan and broader energy policy responses to the Iran war. A structurally higher risk premium on Gulf fertilisers and gas would accelerate diversification of supply and investment in lower‑emission, possibly regional, production capacity—but the transition period is likely to be marked by tight balances, elevated prices and heightened basis risk across key agricultural commodities.

CMB Market Insight

France’s call to suspend CBAM on fertilisers crystallises the tension between climate policy and food security in an environment of acute geopolitical stress. For commodity traders and industrial buyers, CBAM has become a critical variable in fertiliser pricing and trade strategy, with policy shifts capable of re‑pricing markets in short order.

Until there is clearer guidance from Brussels, risk management will hinge on diversified sourcing, close monitoring of policy signals and conservative assumptions on logistics and input costs. Fertiliser and grain markets are moving into a phase where regulatory decisions are as important as fundamentals in driving prices, underlining the need for integrated political and market analysis in trading and procurement decisions.
