** Scotiabank says U.S. President Donald Trump's tariffs on Canadian potash imported to U.S. could meaningfully alter trade flow and producer economics

** Brokerage says "the 25% tariffs on Saskatchewan potash could enable Russia, Israel and Jordan to challenge the market share long held by the Canadian producers"

** However, brokerage notes that distribution networks and logistics systems built by Nutrien NTR.TO and Mosaic MOS.N cannot be replicated overnight

** NTR supplies nearly half of the U.S. potash, and one-third comes from MOS, per Scotiabank estimates

** Notes that while some potash benchmarks have moved higher on inventory build in anticipation of higher prices, farmers are at risk of pushing back on higher prices as it is a lower ranked crop input, which would weigh on fertilizer companies
