The U.S. Court of International Trade has upheld the Department of Commerce’s final remand redetermination regarding antidumping duties on diffusion-annealed, nickel-plated flat-rolled steel products imported from Japan. This ruling affects Toyo Kohan Co., Ltd., the plaintiff in the case, as it determines the pricing and duties on their steel products sold in the U.S. market. The decision is significant as it reinforces the methods used by Commerce in evaluating fair pricing and duties on imported goods.

The case, Toyo Kohan Co., Ltd. v. United States, Court No. 24-00261, began with a dispute over the appropriate date of sale for Toyo Kohan’s U.S. sales and the methodology used to analyze pricing differences. The court’s ruling is crucial for companies involved in international trade, as it clarifies how sales prices are determined and the implications for antidumping duties.

Toyo Kohan Co., Ltd. is a Japanese manufacturer of steel products, while the defendant is the United States government, specifically the Department of Commerce. The defendant-intervenor, Thomas Steel Strip Corporation, is a U.S. company that has a vested interest in the outcome of the case as it competes with imported steel products. The dispute arose during the administrative review of the antidumping duty order covering Toyo Kohan’s products, which examined sales from May 1, 2022, to April 30, 2023.

The initial review by Commerce found that Toyo Kohan had a dumping margin of 4.44 percent. However, the court remanded the case back to Commerce, stating that the use of the shipment date as the date of sale was unsupported by substantial evidence. The court indicated that the billing documentation at the time of shipping was “virtually meaningless” and did not accurately reflect the final terms of sale. The court also noted that the differential pricing analysis needed to be reevaluated in light of a recent Federal Circuit decision.

In the remand results issued on February 18, 2026, Commerce maintained that the shipment date was the appropriate date of sale but revised its differential pricing analysis. The court ruled that Commerce’s decision to continue using the shipment date was reasonable, stating, “Commerce reasonably concluded that the material terms of the sale were established on the shipment date.” The court also noted that Commerce had stopped using the Cohen’s d test for its differential pricing analysis and instead applied a new price difference test, which resulted in a slight increase in Toyo Kohan’s dumping margin to 4.58 percent.

The ruling has significant implications for Toyo Kohan and other companies involved in international trade, particularly those exporting goods to the U.S. The court’s decision supports Commerce’s approach to determining the date of sale and reinforces the importance of accurate pricing analysis in antidumping duty investigations. This case sets a precedent for how similar disputes may be handled in the future, particularly regarding the methodologies used by Commerce in evaluating fair pricing.

The court's decision also highlights the ongoing complexities in international trade law, especially as it relates to antidumping duties. Companies must be aware of the implications of this ruling as it may affect their pricing strategies and the calculation of duties on imported goods. The ruling emphasizes the need for transparency and accuracy in sales documentation to ensure compliance with U.S. trade regulations.

Moving forward, Toyo Kohan has the option to appeal the court’s decision. However, the outcome of any potential appeal remains uncertain. The case underscores the importance of legal clarity in international trade practices and the ongoing challenges faced by companies navigating these regulations. As the global market continues to evolve, businesses must stay informed about legal developments that could impact their operations.
