Core tip: Over the past week, U.S. tariffs have largely been implemented, with India shrimp facing tariffs as high as 25%, and Ecuador's rate rising from 10% to 15%. Affected by the tariff impact, the ex-factory price of Indian South American white shrimp has significantly dropped, and Ecuador is also facing considerable downward pressure; meanwhile, production areas in Vietnam, Indonesia, and Thailand are gradually beginning to adapt to U.S. tariffs, with prices fluctuating.
