The market for frozen fillets of imported tilapia and pangasius is experiencing challenges due to environmental issues in China and Vietnam, leading to tight supply and rising prices. A typhoon in Hainan has impacted tilapia production, while Vietnam's pangasius faces weather-related pressures. Despite these challenges, a favorable preliminary anti-dumping duty ruling for Vietnamese pangasius could enhance competitiveness. In 2024, U.S. imports show a shift, with pangasius surpassing tilapia, except in January. The market remains cautious, with supply recovery hinging on environmental and processing improvements, and an upcoming decision on pangasius tariffs could further influence the market.
