NASHVILLE, TN – President Trump’s threat to impose tariffs on Canadian fertilizer imports has created immediate uncertainty for spring supply and pricing, according to analysis from Josh Linville, Vice President of Fertilizer at StoneX. The U.S. relies heavily on Canada for several key nutrients, making the market highly sensitive to policy shifts.
Potash represents the largest exposure: about 90 percent of U.S. potash imports come from Canada, meaning any tariff would likely raise farmer costs to keep tons moving south. Ammonia markets face similar pressures, as Canada accounts for nearly half of U.S. imports. UAN could also rise in price, with Canada responsible for roughly 20 percent of U.S. inflows. Urea impacts should be minimal because Canada ships relatively little to the U.S. market.
Global conditions add to uncertainty, as Europe’s nitrogen output remains constrained, China slows phosphate exports, and potash trade remains unusually quiet.
Farm-Level Takeaway: Canadian tariffs would raise costs for potash, ammonia, and UAN, increasing spring fertilizer risk.
