U.S. Department of Commerce Finds Anti-Dumping on Steel from Taiwan

Estimated reading time: 3–5 minutes

On May 18, 2026, the U.S. Department of Commerce released the final results of their review on anti-dumping duties for certain corrosion-resistant steel products imported from Taiwan. The review determined that these steel products were being sold in the U.S. at less than fair value from July 1, 2023, to June 30, 2024.

The investigation involved multiple companies, including Prosperity Tieh Enterprise Co., Ltd. (Prosperity) and Sheng Yu Steel Co., Ltd. (SYSCO), which were found to have no dumping margin, indicating their practices were fair. However, Great Grandeul Steel Company Limited was found to have a dumping margin of 0.99 percent.

The review process began with preliminary results announced on January 8, 2026. Interested parties, including Prosperity and Steel Dynamics, Inc., had submitted their comments during the review period. The final memorandum addresses all submitted issues and decides on the appropriate measures.

Companies not selected for a detailed review received a rate derived from previously established methods. These methods ensure fair competition among U.S. domestic products and imported goods.

The Department of Commerce will instruct Customs and Border Protection on the assessment of duties, ensuring fair competition. For entries made during the reviewed period where companies did not know the goods were destined for the U.S., duties will be assessed at a rate of 11.04 percent, which is the default rate for such situations.
