U.S. Department of Commerce Maintains Antidumping Duties on Steel Wire Strand Imports

Estimated reading time: 3–5 minutes

The United States Department of Commerce (Commerce) has announced the final results of the fourth sunset reviews of antidumping duty orders on prestressed concrete steel wire strand from five countries: Brazil, India, Mexico, the Republic of Korea, and Thailand. This decision, officially released in the Federal Register on April 10, 2026, finds that ending these duties would likely lead to continued dumping of the product in the U.S. market.

The antidumping duties were first ordered in January 2004. Commerce reviewed the orders again starting October 3, 2025, to decide if the duties were still needed. This process is called a sunset review.

Commerce received timely notices from U.S. producers who want to keep the duties. These companies are Insteel Wire Products, Sumiden Wire Products, and Wire Mesh Corp. They are considered “domestic interested parties.”

These U.S. producers sent Commerce detailed responses by November 3, 2025. No foreign producers responded to the review. Because of this, Commerce conducted an expedited review.

The publication explains that the government shutdown in November 2025 delayed some deadlines. However, they were able to complete their findings by April 7, 2026.

Commerce decided that removing the duties would likely lead to continued dumping. This means foreign producers might sell their products at unfair prices in the U.S. market again.

Commerce says that if the duties ended, dumping margins would likely be as high as 118.75% for Brazil, 102.07% for India, 77.20% for Mexico, 54.19% for Korea, and 12.91% for Thailand.

Commerce’s role is to protect U.S. companies from unfair trade practices. They will continue to enforce these duties, and interested parties must follow the rules for handling sensitive information related to this case. This decision helps ensure fair competition and supports U.S. producers in the steel industry.
