Yes — dried mushrooms, particularly certain preserved or prepared varieties from specific origins, have been subject to antidumping duty orders in the past. Fresh or chilled mushrooms generally have a different duty profile. Importers should check current antidumping and countervailing duty orders with CBP before sourcing.

Imported mushrooms are subject to FDA food facility registration, prior notice of arrival, and FSMA Foreign Supplier Verification Program requirements. Country-of-origin labeling (COOL) applies at retail, and any mushroom marketed as organic must meet USDA National Organic Program certification standards.
