Korea Steel Plate Antidumping Review: Duty Rates Set for 2024–25
The U.S. Department of Commerce concluded its administrative review of antidumping duties on cut-to-length carbon-quality steel plate from South Korea for the February 2024–January 2025 period. Commerce determined that Korean producers and exporters sold the product below normal value, confirming dumping occurred. This review sets new antidumping duty rates applicable to shipments during the review period and informs future duty assessments on Korean steel plate imports.

On May 8, 2026, the U.S. Department of Commerce published the final results of its administrative review of antidumping duties imposed on certain cut-to-length carbon-quality steel plate products from the Republic of Korea. The review covered the period February 1, 2024, through January 31, 2025.
Commerce determines that the producers and exporters subject to this administrative review made sales of certain cut-to-length carbon-quality steel plate products (CTL plate) from the Republic of Korea (Korea) at prices below normal value during the period of review.
What is cut-to-length carbon-quality steel plate?
Cut-to-length (CTL) carbon-quality steel plate falls under HS Chapter 72 (iron and steel). These are flat-rolled products of carbon steel, typically used in industrial manufacturing, construction, and heavy equipment production. The antidumping investigation focuses on whether Korean mills are underselling their U.S. competitors to capture market share unlawfully.
Who is affected
Importers of Korean-origin CTL plate—including domestic steel mills, service centers, and end-use manufacturers—must pay antidumping duties on subject merchandise. Commerce's final determination establishes the dumping margins and duty rates that U.S. Customs and Border Protection (CBP) will use to assess duties on entries during the February 2024–January 2025 period and assess liquidation instructions on pending entries.
Producers and exporters in South Korea are directly affected, as the final rates determine their cost of doing business and competitiveness in the U.S. market. Importer margins will be recalculated based on Commerce's findings.
Next steps
CBP will issue cash-deposit rates and liquidation instructions for entries covered by this review. Importers should verify the final duty rate applicable to their entries with their customs brokers or freight forwarders and reconcile any overpayments or underpayments of estimated duties.
What this means for shippers
If you import Korean CTL plate (HS 7208–7210, broadly), confirm the final antidumping duty rate with your broker and reconcile duty payments for February 2024–January 2025 entries immediately. Failure to account for accurate antidumping assessments risks liquidation adjustments, penalties, and cash-flow disruption. Review your landed-cost estimates using current rates and coordinate with your supplier on duty-cost pass-through.
