This study applies Barten (1993) general synthetic demand system approach with its nested models to analyze the changes in the import demand structure of Tilapia in US during the US-China trade war. The results show that the model mixed by the CBS type expenditure response and Rotterdam type price response demand system is the best to describe US Tilapia fillets import demand. While the mixed model of Rotterdam type expenditure response and NBR price response is the best model for the US Tilapia Frozen whole fish import demand. US Tilapia fillets import demand structure has been significantly impacted by the US-China trade war. The importing countries, including China, Indonesia, Taiwan, and rest of world, have become more flexible in their price elasticity. The influence of China's import prices to Taiwan import quantity has become weakened, whereas the substitution between Indonesia and Taiwan becomes stronger. While the US-China trade war has no significant impact on the structure of U.S. Tilapia whole fish import demand. China's own import price elasticity of frozen whole fish is not elastic, while Taiwan's is significantly elastic. There is a significant competition relationship between Thailand and Taiwan's frozen whole fish, but the impact of Chinese import prices on Taiwan import quantity is not significant.
