Prepared or Preserved Mushrooms and Truffles

Yes — certain preserved mushroom products, particularly those originating in specific Asian countries, have been subject to US antidumping duty orders. Importers should check the current scope of any active orders with the US Department of Commerce and confirm applicable cash deposit rates before shipment.

While both fall under SITC 05674, the US HTS schedule distinguishes truffles from mushrooms at finer classification levels. Truffles — whether fresh, chilled, frozen, or preserved — are typically separated into their own tariff lines due to their distinct commercial value and botanical classification. Confirming the correct 10-digit HTS code with a licensed customs broker is advisable given the significant duty and valuation implications.
