The U.S. International Trade Commission’s decision in December 2023, indicating potential harm to the U.S. industry from imports of frozen vannamei from Ecuador, India, Indonesia, and Vietnam, could significantly affect U.S. consumers and suppliers worldwide. If antidumping and countervailing duties are imposed following these investigations, initiated in October 2023, U.S. consumers might face increased costs for vannamei shrimp. Meanwhile, global suppliers could encounter challenges adapting to these new market conditions, reshaping the international seafood trade landscape.
