A-851-804 is a U.S. antidumping duty (AD) order on seamless carbon and alloy steel standard, line, and pressure pipe from Czech Republic, issued by the U.S. Department of Commerce. It is part of the trade-remedy regime that levies cash deposits at entry on imports found to be sold below fair value (AD) or to benefit from foreign government subsidies (CVD).
The country-wide cash deposit rate for A-851-804 is 51.07%. This rate applies to importers of non-listed manufacturers/exporters from Czech Republic. 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-851-804 took effect on April 26, 2021 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 (37 flagged); and (2) the product's country of origin — this order applies to imports from Czech Republic. 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.
