European fertiliser importers are weighing carbon-border costs under the EU’s Carbon Border Adjustment Mechanism alongside tariffs, natural gas price volatility and the risk of relying on a narrow set of external suppliers. The resulting procurement challenge is not limited to carbon pricing alone, because delivered prices also depend on energy inputs, logistics and trade measures. As a consequence, sourcing decisions increasingly require simultaneous assessment of emissions evidence, availability and total landed cost.
Early-2026 ammonia trade data point to changing supply patterns that market participants are linking to CBAM-related treatment. S&P Global shipping figures show EU seaborne ammonia imports at about 717,000 tonnes in the first quarter of 2026, down from 787,000 tonnes in the previous quarter. US shipments fell from roughly 90,000 tonnes to 40,000 tonnes over the same period, while Algeria represented around 30% of first-quarter arrivals. Some participants attributed part of the US decline to the default emissions treatment applied under CBAM.
Those figures relate specifically to seaborne ammonia and do not cover the full range of fertilisers or all EU import categories. Ammonia and nitrogenous fertilisers covered by CBAM can fall under different customs classifications and production routes, which affects how emissions are assessed. By contrast, phosphate and potash fertilisers cannot be automatically included in carbon-exposure estimates simply because they are agricultural inputs. Reliable assessments therefore require product-specific classifications and data rather than broad assumptions.
Natural gas remains central to conventional ammonia economics and therefore to how suppliers compete under carbon-border rules. It is a major feedstock and cost component in ammonia production, and plant emissions profiles depend on operational efficiency, fuel use and the hydrogen production route. Upstream inputs relevant to the production chain also influence embedded emissions outcomes. For buyers comparing offers, these factors determine whether carbon costs align with the delivered price or diverge from it.
Where producers can provide credible installation-specific emissions data, they may be able to demonstrate a lower embedded-emissions footprint than default values would suggest. This depends on whether the CBAM rules allow verified actual figures in place of default approaches. Access to reliable production information can therefore affect supplier comparisons even when nominal certificate-related adjustments appear similar. In practice, emissions evidence becomes part of commercial differentiation rather than a purely regulatory consideration.
CBAM treatment for fertilisers also differs from other covered industrial sectors, which complicates cross-sector comparisons of carbon costs. The European Commission’s default-value mark-up for fertilisers is not the same as mark-ups applied to steel, cement and aluminium. Without accounting for these distinct rule sets, comparing default-value adjustments across sectors could lead to misleading conclusions about relative carbon burdens. This matters for procurement teams that may otherwise benchmark suppliers using simplified assumptions.
The certificate reference price is one input into CBAM calculations but not a complete measure of liability. The third-quarter 2026 CBAM certificate reference price was €82.32 per tonne of CO₂ equivalent, influencing the economics of covered imports while not determining total responsibility by itself. Liability also depends on free-allocation benchmarks, emissions figures accepted under the rules and any recognised carbon payments made in the country of production. Importers must weigh these elements alongside natural gas supply risks, freight charges, trade-defence measures and any relevant product-specific customs duties.
A lower certificate-related cost does not automatically translate into the lowest overall purchase price because other cost drivers can dominate competitiveness. Gas prices, production efficiency and logistics can materially influence which supplier offers the most workable delivered terms. This interaction helps explain why shifts in trade flows cannot be read as a single-cause outcome tied only to CBAM defaults or certificate prices. Energy-market conditions and supply availability remain key variables alongside carbon-border compliance.
Trade policy is adding further complexity to diversification strategies for fertiliser procurement in Europe. EU policy towards Russian and Belarusian fertiliser imports introduces additional variables into purchasing decisions through duties and diversification measures that can push buyers toward alternative suppliers. Those alternatives may include producers whose emissions advantages are small or not yet verified with installation-level evidence suitable for CBAM purposes.
Changes in origin shares therefore require careful interpretation because multiple factors can move purchasing patterns at once. A declining share for a particular origin does not necessarily indicate that CBAM is responsible; tariffs, energy prices, shipping costs and supply availability can also shape buying behaviour. Short-term increases in fertiliser prices can further raise political pressure because higher input costs affect farmers’ production budgets. For importers and distributors, separating carbon pricing effects from broader trade and energy-market developments becomes more important as price volatility persists.
Commercial contracting is also likely to become more data-intensive as distributors seek emissions information during negotiations. European fertiliser distributors may increasingly need reliable supplier emissions data as part of annual contracting alongside product specifications, delivery schedules and credit terms. Contracts that provide access to relevant production information could help importers assess potential CBAM exposure and compare offers on a more consistent basis across suppliers.
Financing inventory ahead of planting seasons adds another layer of uncertainty because timing mismatches can affect risk management. Distributors may face a gap between when import-related costs are incurred and when those costs can be passed on to farmers, particularly when demand is price-sensitive or when supply contracts limit immediate price adjustments. In this setting, emissions evidence, product availability and financial risk must be evaluated together rather than sequentially.
Europe’s dual objective of securing affordable fertiliser supplies while reducing embedded emissions does not automatically align in day-to-day procurement decisions. Buyers need sufficient nitrogen products at workable prices while CBAM creates incentives tied to accounting for carbon emissions where supported by applicable rules favour lower-emission production. The commercial outcome will depend on how carbon costs interact with energy prices, trade measures and the quality of supplier data available for compliance purposes.
Overall, early-2026 ammonia flow changes illustrate how CBAM-related default treatment can intersect with energy-linked competitiveness and shifting supply routes. Yet the same data also underline that liability outcomes depend on more than certificate reference prices: accepted emissions figures, free-allocation benchmarks and recognised carbon payments all shape final calculations alongside logistics and trade policy constraints already affecting procurement choices.
