Executive Order 14231 exempts USMCA-compliant Canadian goods from the fentanyl tariffs from 7 March and cuts the rate on Canadian potash to 10%
President Trump signed Executive Order 14231 on 6 March 2025, amending the February fentanyl tariff order. From 7 March, Canadian goods that qualify under the USMCA (CUSMA) trade agreement were exempt from the tariffs, and the rate on Canadian potash that does not qualify was cut from 25% to 10%, the rate already applied to energy. The same day Finance Minister Dominic LeBlanc said Canada would push back its second round of counter-tariffs, on C$125 billion of US goods, from around 25 March to 2 April, Bloomberg reported; the 25% counter-tariffs on about C$30 billion of US goods stayed in place. Canada never enacted the second round.

Claims that rest on this event
- US tariffs spare raw resources and hit processed goods. Energy was taxed at 10% or exempt in every round, the potash rate was cut to 10%, and the 2026 Section 338 tariffs exempt energy, potash, critical minerals and fish, while steel, aluminum, copper, autos and lumber took the heaviest tariffs.
On 6 March 2025 the US cut its tariff on Canadian potash from 25% to 10%, the rate applied to energy.
- In the foresight thought experiment: the US Treasury lifted sanctions on Belarus's state potash producer in March 2026, and Trump said Belarus 'would like to sell it for a much lower price'. This complicates the idea that the US is securing Canadian supply, and fits plain self-interest: shop for the cheapest input.
In March 2025 the US cut its tariff on Canadian potash to 10%, which the US agriculture secretary presented as a way to hold down farmers' input costs.
Tested hypotheses: a thought experiment
Suppose Washington foresaw and wanted this. Would this event look any different than under the rival readings? This is a deliberately contrarian test, explained here, not the author’s belief. Judgments, not measurements.
Non-discriminating: this event fits the plain self-interest reading and the foresight reading equally. It does not tell them apart. What this means
| Reading | Fit | Why |
|---|---|---|
| I0a Accident Tested hypothesis (intent) | Fits weak | Exempting USMCA goods and cutting potash to 10% protects US farmers and supply chains; this fits self-interest under any of these readings equally. |
| I0b Plain self-interest; Canada's response not considered Tested hypothesis (intent) | Fits weak | Exempting USMCA goods and cutting potash to 10% protects US farmers and supply chains; this fits self-interest under any of these readings equally. |
| I1 Foreseen and welcomed, not the reason Tested hypothesis (intent) | Fits weak | Exempting USMCA goods and cutting potash to 10% protects US farmers and supply chains; this fits self-interest under any of these readings equally. |
| I2 Foreseen and wanted (this level or higher) Tested hypothesis (intent) | Fits weak | Exempting USMCA goods and cutting potash to 10% protects US farmers and supply chains; this fits self-interest under any of these readings equally. |
| I3 Worked-out plan with specific targets Tested hypothesis (intent) | Neutral weak | The order names no Canadian projects and treats Canada as a whole. |
| R-annex Annexation Rival reading | Against weak | Exempting most of Canada's trade within days would be somewhat surprising if the aim were to use economic force to weaken or absorb Canada. |
| R-frag Fragmentation Rival reading | Neutral weak | The order names no Canadian projects and treats Canada as a whole. |
| R-weaken Weaken-Canada rivals (annexation or fragmentation) Rival reading | Against weak | Exempting most of Canada's trade within days would be somewhat surprising if the aim were to use economic force to weaken or absorb Canada. |
