Commerce Department Releases Preliminary Results of Antidumping Duty Review on Mushrooms from Poland

Estimated reading time: 1–7 minutes

The U.S. Department of Commerce has released preliminary results of its review on certain preserved mushrooms from Poland. The review focused on sales from May 1, 2024, to April 30, 2025. The Department’s International Trade Administration has determined that Okechamp S.A., the sole company reviewed, sold mushrooms at less than normal value during this period.

The review comes under the Department’s efforts to enforce antidumping duties, ensuring fair trade practices. According to the Department, Okechamp had a dumping margin of 0.54 percent for their mushroom sales.

Due to government shutdowns in late 2025, the process experienced delays, including a 68-day extension. The Commerce Department intends to verify all information before finalizing results and invites public comments. Parties can submit their views seven days post-verification. Rebuttals can follow within five days after that.

Should Okechamp’s margin remain above zero, U.S. Customs will assess duties on affected entries. The Department will instruct on duties only if margins remain above a de minimis level. Otherwise, liquidation will occur without duties.

In summary, the Department continues to enforce duties, maintaining fair market conditions for U.S. businesses. They remind importers to follow regulations and submit necessary certificates to avoid higher duties in cases of reimbursement.

More updates will follow as the review progresses.
