Canadian canola farmers have reason to celebrate a last-minute deal to at least delay US tariffs. Changing US biofuel policies, however, could dim their excitement.
The two countries agreed Monday to pause for a month 25pc tariffs on most Canadian imports, including agricultural products like canola oil.
While best known for its use in food, canola oil has become an increasingly important ingredient in US biofuel production. Canada exported 800,000 lbs of crude canola oil to the US in 2021, before US regulators allowed more canola-based fuels to qualify for a biofuel mandate, but more than three times that total over just 11 months in 2024 according to customs data. Canola oil from all origins made up around 12pc of the US biomass-based diesel feedstock mix last year.
The challenge for Canada is that policies in the US that helped cement canola oil's role in biofuel production are increasingly encouraging producers to use other feedstocks. The mere threat of tariffs could speed that trend along.
A long-running US tax credit for blenders of biomass-based diesel expired last year and was replaced by the Inflation Reduction Act's "45Z" credit, which requires fuels to meet an initial carbon intensity threshold and then ups the subsidy as emissions fall. This shift was always expected to benefit waste feedstocks over crops, which incur a carbon penalty for land changes and fertilizer use. The clear message to refiners — both from the US government and from California regulators that run the state's influential low-carbon fuel standard — has been to diversify beyond vegetable oils.
But an updated emissions model released by the Department of Energy last month surprised some in the industry by assessing the default carbon intensity of canola-based fuels as too high to automatically qualify for 45Z. Although fuels from soybean oil generally earn some credit, diesels made from canola oil could go from earning $1/USG last year to nothing this year. Before even factoring in potential tariffs, Canadian canola oil appears less attractive for refiners than even competing crops.
Guidance on 45Z is preliminary, meaning canola crushers can push for final rules that are less restrictive. But energy lobbyists say privately that they do not expect the new administration to act with urgency to implement an incentive created by Democratic lawmakers and oriented around climate change. And many Republicans' concern with the credit is not that it is too harsh on canola — but that it is too permissive of foreign feedstocks they see as hurting US crop demand.
The introduction of 45Z could simultaneously leave Canadian biofuel producers less able to backfill canola oil demand if US buyers look elsewhere. The credit can only be claimed by US producers, cutting off subsidies for imported fuels. At the same time, 45Z does not require fuel to be consumed stateside — meaning that US biorefineries can send subsidized fuel abroad to chase additional incentives Canada offers for biofuel usage.
"The on-again off-again status of US tariffs and Canada's counter-tariff response do not alter the bare economics of biofuel production between jurisdictions when one has an exportable tax credit and the other does not," said Fred Ghatala, president of Advanced Biofuels Canada.
The future of renewable diesel production in Canada, previously expected to grow significantly to the benefit of farmers, is in doubt. ExxonMobil's Canadian subsidiary is on track to open a 20,000 b/d renewable diesel plant this year, but other companies collectively representing more production capacity are wavering. Plans for an integrated canola crush and 15,000 b/d renewable diesel facility in Saskatchewan were paused last month. And it is unclear if Braya Renewable Fuels' 18,000 b/d biorefinery in Newfoundland is running now or if Tidewater Renewables' 3,000 b/d British Columbia plant will run after March.
If demand from Canadian biorefineries remains limited, some traders expect that Trump's tariff threats could divert more canola oil previously bound for the US to Europe. But there is no perfect alternative to the US market, which accounted for 91pc of all Canadian canola oil exports in 2023 according to the US Department of Agriculture.
"There is logistics capacity to sell canola oil, seed, or meal abroad. That's certainly an option," said Chris Vervaet, executive director of the Canadian Oilseed Processors Association. "The best option though is to continue to maintain and grow our trade relationship with our most important trade partner, which is the United States."
