Commerce backs 1.62% to 4.97% Canadian Mushroom Us Tariffs
The canadian mushroom us tariffs case moved one step closer on May 13, 2026, when the U.S. Department of Commerce issued a preliminary affirmative ruling on Canadian mushroom producers and set subsidy rates at 1.62% to 4.97% on fresh imports. For growers, that is the first federal finding that could turn into duties once the ruling is formally published in the coming days.
Commerce sets 1.62% to 4.97%
1.62% to 4.97% is the preliminary range the federal government announced for fresh mushroom imports from Canada, and those rates will take effect after publication in the coming days. The ruling found that Canadian mushroom producers received unfair government subsidies, putting the case on track for duties that would change the cost of entering the U.S. market.
May 13, 2026 also marked the first of two major federal trade determinations tied to fresh mushroom imports from Canada. A separate antidumping ruling is expected later this summer, and that second decision could add more duties on top of the subsidy case.
Mark Currie on farm closures
More than nine American mushroom farms have already closed during this period, Mark Currie said, linking the ruling to years of pressure from imports that Giorgi Mushroom Co. says grew significantly while domestic mushroom consumption stayed relatively flat. He called the decision an important step toward restoring fairness for American mushroom growers and said it was a meaningful response to concerns that had distorted competition and threatened domestic production.
“For years, American mushroom growers have faced enormous pressure from unfairly subsidized mushroom imports that distorted competition and threatened domestic production” — Mark Currie. He added: “Yesterday’s ruling marks an important step toward restoring fairness for American mushroom growers, protecting American jobs and preserving strong domestic mushroom production for retailers and consumers across the country. We are encouraged federal investigators recognized the seriousness of these concerns and took meaningful action.”
Giorgi’s uncommon trade case
More than nine farm closures is the sharpest sign of the friction inside this market, especially because Giorgi Mushroom Co. said countervailing duty actions involving Canadian industries are relatively uncommon. The combination leaves U.S. growers with a short-term repricing risk now and a second federal decision later this summer that could stack additional duties onto the first ruling.
More than nine American mushroom farms have already closed during this period, Currie said, and he warned that once domestic farms disappear, they rarely come back. “Giorgi Mushrooms will continue fighting for American mushroom growers, American jobs and the future of domestic mushroom production,” he said, putting the next phase of the dispute on the record before the federal government formally publishes the ruling.
