U.S. Department of Commerce to Maintain Antidumping Duties on Methionine Imports
Estimated reading time: 3–5 minutes
The U.S. Department of Commerce, International Trade Administration, has announced the final results of the expedited first sunset reviews of the antidumping duty orders on methionine from France, Japan, and Spain. This determination follows a review process carried out under the Tariff Act of 1930 and its later amendments.
The Commerce Department concluded that ending the antidumping duty orders would likely result in continued or new instances of dumping. Dumping is when a product is sold in the U.S. at less than its fair value. The antidumping orders were put in place to protect U.S. industries by imposing duties on the imported methionine that is sold at unfairly low prices.
The antidumping duty orders for methionine, which is an important animal feed supplement, were originally published on July 13, 2021, for France, and on September 14, 2021, for Japan and Spain. These orders were set to expire but were reviewed as part of the sunset review process. This process helps determine whether there is a likelihood of dumping continuing or recurring if the orders were revoked.
The review began on June 1, 2026, after the publication of the initiation notice. Novus International, a U.S. company involved in the production of methionine, participated actively in the review. They submitted substantive responses supporting the continuation of the orders.
By July 27, 2026, no responses were received from other interested parties, prompting an expedited review by Commerce. The review process led Commerce to determine likely dumping margins if the orders were revoked, with rates of up to 43.82% for France, 76.50% for Japan, and 37.53% for Spain.
Commerce’s findings ensure that the antidumping duties will remain in place, thereby continuing to protect U.S. industries from unfair competition due to dumping. These findings were detailed in a memorandum and a public notice, both accessible through official channels.
Overall, this decision reflects the U.S. government’s commitment to defending its markets and industries from unfair trade practices while ensuring that local manufacturers remain competitive.
