Are Canadian Mushrooms Dumping Prices on U.S. Farmers? Probe Starts
Published Date: 1/8/2026
Notice
Summary
The U.S. Department of Commerce is starting an investigation to see if fresh mushrooms from Canada are being sold in the U.S. at unfairly low prices. This affects Canadian mushroom exporters and U.S. mushroom growers who want fair competition. The investigation began on January 2, 2026, and could lead to extra duties (taxes) on Canadian mushrooms to protect American farmers.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 2 costs, 1 mixed.
Investigation Could Lead to Duties
On January 2, 2026, the U.S. Department of Commerce started an antidumping (less-than-fair-value) investigation of fresh mushrooms from Canada. The investigation could lead to extra duties (taxes) on Canadian mushrooms to protect U.S. mushroom growers if Commerce and the ITC issue findings that support duties.
Estimated Dumping Margins Identified
Commerce's review of the petition found estimated dumping margins for Canadian fresh mushrooms ranging from 26.29 percent to 38.31 percent based on comparisons of U.S. price to normal value. These percentages are the estimated margins Commerce used to justify initiating the less-than-fair-value investigation.
Products Covered: Agaricus Fresh Mushrooms
The investigation covers fresh mushrooms of the genus Agaricus (including Agaricus bisporus and commonly called button, cremini, portobello, baby bella, and similar names), whether whole or sliced/diced, organic or not, and regardless of packaging. Commerce notes these mushrooms are classifiable under HTSUS statistical reporting number 0709.51.0100 and the written scope description controls.
