A-455-806 is a U.S. antidumping duty (AD) order on preserved mushrooms from Poland, issued by the U.S. Department of Commerce.

The country-wide cash deposit rate for A-455-806 is 34.32%. This rate applies to importers of non-listed manufacturers/exporters from Poland. Individual exporters and producers may have lower (or higher) case-specific rates from Commerce administrative reviews — see the manufacturer rates linked from this page where available.
A-455-806 took effect on May 23, 2023 and is currently in active status — cash deposits apply at entry on every shipment in scope.
Two factors determine scope: (1) the product's HTS code(s) and physical characteristics — covered codes are listed on this page (6 flagged); and (2) the product's country of origin — this order applies to imports from Poland. The order's scope text — also on this page — is the legally binding description. When borderline cases arise, importers can request a formal scope ruling from Commerce. Tandom's lookup tool matches your HTS + origin against every active order in seconds.
