On June 2, 2026, the US International Trade Commission and Commerce Department finalized antidumping duties on prestressed concrete steel wire strand (PCWS) originating from Brazil, India, Japan, Mexico, South Korea, and Thailand, according to a notice published in the Federal Register.
The determination concludes that producers in these six countries have been exporting PCWS to the United States at prices below fair value, injuring the domestic US PCWS industry. The action requires importers to post additional antidumping duties at customs entry on all covered merchandise.
Prestressed concrete steel wire strand from the named countries is subject to antidumping duties effective as of the Federal Register publication date.
Affected merchandise falls under HS Chapter 72 (iron and steel and articles thereof). Importers bringing in PCWS from Brazil, India, Japan, Mexico, South Korea, or Thailand must now classify entries correctly and declare the applicable antidumping duty rate at the time of entry.
The duty rates vary by country and by exporter; specific rates are detailed in the Federal Register notice. Importers should obtain the exact duty percentage applicable to their supplier before entering goods, as failure to declare the correct duty may result in penalties, entry rejection, or liquidation adjustments.
Forewarders and merchants sourcing PCWS from these countries face an immediate cost increase on all new imports. The decision becomes effective immediately upon publication in the Federal Register, so any entries filed after June 2, 2026, are subject to the new rates. Existing merchandise in transit or in-bond warehouses may qualify for delayed entry or warehouse withdrawal under specific provisions, but timing is critical.
What this means for shippers
If you source prestressed concrete steel wire strand from Brazil, India, Japan, Mexico, South Korea, or Thailand, your landed cost just increased by the antidumping duty margin (often 20–50% or more). Recalculate pricing immediately and notify your suppliers or consider switching origin. Request country-of-origin documentation and verify that any transshipment claims are fully supported, as false origin declarations will trigger fraud penalties. Update your landed-cost models to include the antidumping duty before quoting customers. Check our tariff tool to confirm exact duties by exporter and country.
