The European Union's Carbon Border Adjustment Mechanism (CBAM) is set to shake up the global ammonia market, and US producers are in for a rude awakening. A recent draft proposal from the EU's CBAM committee has left industry insiders stunned, as it suggests a significant hike in the carbon cost for US-origin ammonia. But here's where it gets controversial: this move could potentially disrupt the longstanding trade relationship between the US and Europe in the ammonia sector.
According to the draft documents, reviewed by Platts (part of S&P Global Energy), the default carbon intensity for US-made ammonia is slated to jump from 2 mtCO2e during the transitional phase to a whopping 3.41 mtCO2e when the definitive phase kicks in on January 1. Is this a fair assessment, or is the EU penalizing US producers? The documents also reveal a decrease in the benchmark value for ammonia imported into the EU, with importers facing a lower benchmark free allowance of 1.522 mtCO2e, down from 1.57 mtCO2e.
And this is the part most people miss: the combined effect of the reduced benchmark allowance and the increased default carbon intensity for US ammonia could see CBAM exposure for importers skyrocket from around $45/mt to $180/mt. One Europe-based trader called it "disappointing," while another argued it was "torpedoing the very thing CBAM should be doing" – encouraging lower carbon emissions. They predict this could effectively halt the flow of US-origin ammonia into Europe.
To put this in perspective, in the first nine months of 2025, the EU imported 2.06 million metric tons of ammonia, with nearly 10% (202,000 mt) coming from the US, according to S&P Global Market Intelligence's Global Trade Atlas. A European buyer expressed hope that the draft documents "do not come true," calling the proposal "a bit unfair on gas-based ammonia producers." The US, they noted, has been a reliable ammonia supplier to Europe.
But here's the kicker: new ammonia plants are expected to come online in the US by 2026, with at least two incorporating carbon capture and sequestration technology, which should significantly reduce their carbon footprint. Yet, under the proposed CBAM rules, US producers would still face higher costs, leaving them heavily reliant on verification schemes to prove their lower carbon intensity. Another European buyer bluntly stated, "It looks like the EU wants a tariff on ammonia from the US, implemented via CBAM."
Interestingly, default values for other major ammonia exporters to Europe remain largely unchanged or have seen minor adjustments. For instance, Russia's default value increased slightly from 2.25 mtCO2e to 2.28 mtCO2e, while Algeria's stayed the same. Egypt and Trinidad & Tobago saw small decreases, from 2.08 mtCO2e to 2.05 mtCO2e and 2.43 mtCO2e to 2.42 mtCO2e, respectively.
The draft also includes a silver lining for the fertilizer industry, with a 1% penalty markup for using default values, down from the originally planned 30%. However, this does little to ease the concerns of US ammonia producers and their European buyers.
So, what do you think? Is the EU's CBAM proposal a fair step toward reducing global carbon emissions, or is it an unfair burden on US ammonia producers? Could this move backfire, disrupting global ammonia trade and potentially increasing costs for European consumers? Share your thoughts in the comments – this is a debate worth having!
