The U.S. Court of International Trade has ruled on the antidumping duties concerning imports of xanthan gum from China. This decision affects Neimenggu Fufeng Biotechnologies Co., Ltd. and other related companies, as they will no longer face these duties. The ruling is significant as it reflects ongoing trade disputes between the U.S. and China, particularly in the biotechnology sector.

The case, known as Neimenggu Fufeng Biotechnologies Co., Ltd. v. United States (Consol. 23-00068), centers on the administrative review of antidumping duties from 2020 to 2021. Antidumping duties are tariffs imposed on foreign imports that are believed to be priced below fair market value, which can harm domestic industries. The ruling was issued on May 12, 2026, by Judge Gary S. Katzmann.

Background

Neimenggu Fufeng Biotechnologies Co., Ltd. and its affiliates, including Shandong Fufeng Fermentation Co., Ltd. and Xinjiang Fufeng Biotechnologies Co., Ltd., are major producers of xanthan gum, a thickening agent widely used in food and industrial products. The companies contested the U.S. Department of Commerce's determination of antidumping duties, arguing that the valuation of their production inputs was incorrect.

The dispute reached the court after a series of administrative reviews by the Department of Commerce, which initially set high dumping margins for the companies. The companies claimed that these duties were unfairly high and did not accurately reflect the actual costs of production. Their case was complicated by previous rulings that required the Department of Commerce to reconsider its methodology for calculating these duties.

This case is part of a broader trend of trade tensions between the U.S. and China, particularly in industries where both countries compete heavily. The U.S. has imposed various tariffs and duties on Chinese imports to protect its domestic industries, leading to numerous legal battles in U.S. courts.

The Ruling

In this latest ruling, the court upheld the findings of the Department of Commerce following a second remand. The Department of Commerce had been instructed to reevaluate its valuation of Fufeng's coal inputs, which are essential for the production of xanthan gum. The court noted, “Commerce complied with the court’s instructions to reconsider its valuation of Neimenggu Fufeng Biotechnologies Co.,” leading to the conclusion that the proper subheading for the valuation of Fufeng’s coal was “HTS 2701.19.”

As a result of this reevaluation, the Department of Commerce determined that Fufeng's revised dumping margin was zero percent. This ruling also affected Meihua Group International (Hong Kong) Limited and Xinjiang Meihua Amino Acid Co., Ltd., which were consolidated plaintiffs in this case. The court stated, “Because the separate rate for Meihua was based on Fufeng’s weighted-average dumping margin, Commerce also recalculated Meihua’s separate rate to be zero percent.”

On May 1, 2026, both Fufeng and Meihua expressed their support for the Second Remand Results and indicated that they would not be filing any further comments. Subsequently, the government requested that the court sustain these results, which the court ultimately agreed to do.

Impact

This ruling has significant implications for the companies involved and the broader market for xanthan gum. With the antidumping duties set to zero, Fufeng and Meihua can now import their products to the U.S. without the additional financial burden of these tariffs. This could potentially lower prices for consumers and increase competition in the market.

The decision also highlights the importance of accurate valuation in trade cases. By recognizing the correct valuation of inputs, the court has set a precedent that could affect future cases involving antidumping duties. It underscores the need for the Department of Commerce to carefully consider the methodologies used in calculating dumping margins, particularly in complex industries like biotechnology.

Furthermore, this ruling may influence other companies facing similar trade disputes with the U.S. government. It signals that companies can successfully challenge antidumping duties if they can demonstrate that the calculations used by the Department of Commerce are flawed.

What's Next

Details were not available in the court filing regarding whether this decision can be appealed. However, parties involved in such cases often have the right to challenge court rulings. There may also be related cases pending that involve similar issues of antidumping duties and valuations in the biotechnology sector.
