The U.S. Department of Commerce announced preliminary countervailing duties on fresh Canadian white mushrooms exported to the United States, following a trade complaint filed by domestic mushroom producers. The decision, released May 13, marks a significant escalation in the U.S.-Canada produce trade relationship. The duties are preliminary, meaning a final determination is still to come.
U.S. mushroom growers, led by companies like Giorgi Mushroom Co., have argued that Canadian producers benefit from unfair government subsidies that allow them to undercut American pricing. Canada is a major supplier of fresh mushrooms to the U.S. market, so these duties have real implications for buyers and retailers who depend on that supply.
Expect pricing volatility on fresh white mushrooms as the market adjusts. Buyers should start mapping alternative sourcing options now, and watch for a formal determination from Commerce that could make these duties permanent.
