Opinion: Potash Pivot: Trump's Belarus Gambit Signals New Terms for Canadian Trade

By targeting a deal with Belarus to undercut Canadian fertilizer prices, President Trump is signaling that Canada's status as a primary supplier is no longer a guarantee of security.
U.S. President Donald Trump announced Monday that Washington is pursuing a "massive Deal" to purchase potash from Belarus, a move explicitly designed to secure pricing that is "substantially less" than what the U.S. currently pays to Canada.
On the surface, this is a play for cheaper inputs for American farmers and ranchers. But looking deeper, the move serves as a calculated signal: Canada's trade security is now conditional. By courting a close ally of Russia, Trump is demonstrating a willingness to sideline a primary partner to gain leverage in ongoing trade disputes.
**The Mechanism of Dependence**
Canada currently holds a dominant position in the U.S. fertilizer market. According to reporting from CityNews Toronto, Nutrien Ltd.—the world's top potash producer based in Saskatchewan—states that Canada provides more than 80 percent of the potash used on U.S. farms. The scale of this relationship is immense; Natural Resources Canada reports that the U.S. imported $4.2 billion worth of potash in 2025, representing nearly half of Canada's total potash exports.
While potash remains exempt from U.S. tariffs, Trump's pivot suggests that no sector is off-limits if he believes a cheaper alternative exists. The shift is particularly jarring given that Belarus is an authoritarian state and a close ally of Russia.
**The Belarus Equation**
The path to this deal has already been partially cleared. Belarusian President Alexander Lukashenko stated on Sept. 11 that Belarus has resumed potash sales to the U.S. following the lifting of American sanctions. However, the deal is not without friction; Lukashenko is demanding the return of more than $40 million US currently frozen within the U.S. banking system.
Logistically, the pivot faces headwinds. CBC reports that sanctions and the closure of a key port on Lithuania's Baltic coast have previously made shipping Belarusian supplies through Russia's Arctic expensive. Even if the port of Klaipeda in Lithuania were opened to Belarusian exports, Josh Linville, a fertilizer analyst at StoneX, told CBC that the current low value of potash makes such a journey across the Atlantic difficult to justify.
**What It Means**
From a supply chain perspective, the impact may be negligible. Linville noted that the U.S. has not struggled to find potash and has "more than enough to go around," suggesting the real pressures are currently on nitrogen and phosphate supplies due to the Iran war.
However, the geopolitical message is loud. By publicly targeting a deal with Belarus to "sideline" Canada, Trump is notifying Ottawa that its market share is a vulnerability, not a shield. The move follows other aggressive rhetoric, including Trump's suggestions that not doing business with Canada is an option and threats of new tariffs over a Canada-EU alliance.
As of Monday, Canada-U.S. Trade Minister Dominic LeBlanc and Nutrien had no immediate comment on the development. For Canada, the lesson is clear: trade dominance is no longer a safeguard against volatility when the U.S. administration views diversification as a weapon.
