Poland Faces New Duties on Canned Mushrooms Sold in U.S.
Published Date: 5/22/2026
Notice
Summary
The U.S. Department of Commerce found that Okechamp, a Polish mushroom seller, sold preserved mushrooms in the U.S. at unfairly low prices from late 2022 to April 2024. Because of this, certain extra duties will apply to their imports starting May 22, 2026. This decision affects Okechamp and helps protect U.S. mushroom sellers from unfair competition.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 3 costs, 1 mixed.
All-Others Rate Stays at 34.32%
The notice keeps the 'all-others' antidumping cash deposit rate at 34.32 percent. Commerce will instruct U.S. Customs and Border Protection to liquidate unreviewed entries at the all-others rate if an intermediate company in the transaction has no established rate.
Importers Must Certify Reimbursement Risking Double Duties
Importers must file a certificate about reimbursement of antidumping duties before liquidation of relevant entries for the period of review. If an importer fails to file this certificate, Commerce may presume reimbursement occurred and assess double antidumping duties.
U.S. Mushroom Sellers Get Trade Protection
The Commerce finding is intended to protect U.S. mushroom sellers from unfairly low-priced imports by applying duties to Okechamp. The final action is explicitly described as helping protect U.S. mushroom sellers from unfair competition.
Okechamp Imports Face 2.55% Duty
The Department of Commerce found Okechamp sold certain preserved mushrooms at unfairly low prices for the period November 3, 2022 through April 30, 2024. As of May 22, 2026, imports of Okechamp mushrooms will be subject to an antidumping cash deposit rate equal to the final weighted-average dumping margin of 2.55 percent for shipments entered or withdrawn for consumption on or after publication.
Importer-Specific Assessment Rules and De Minimis Cutoff
Commerce will calculate importer-specific ad valorem antidumping assessment rates based on the ratio of dumping to entered value for each importer's examined sales. If an importer-specific assessment rate is zero or de minimis (less than 0.5 percent), those entries will be liquidated without regard to antidumping duties.
