The US will impose 35% tariffs on Canadian imports from August 1, 2025, but US potash markets are expected to be largely unaffected. Potassium fertilizers are covered under USMCA (HS 310420) and were omitted from earlier tariffs.
Trade talks between the US and Canada remain unresolved, and some distributors expect a possible 10% tariff on potash.
Canada supplies most US potash imports, so any tariff applied to potash would raise US delivered costs. Current USMCA coverage limits that risk, but an unresolved negotiation leaves uncertainty for North American buyers.
