Summary：
China's 15% tariff on U.S. corn in 2025 triggered a 97% import collapse, driving self-sufficiency to 95.6% and shifting sourcing to Brazil (68% of imports). Domestic prices rose 9% to ¥2,850/ton, while Brazil's 2025 exports may surpass the U.S., reshaping global trade under China's tariff-led strategy.
U.S.-China Tariff War Escalates: How 15% Duties Reshaped Global Corn Trade
-
Direct Cause: In March 2025, the U.S. imposed a 10% tariff on Chinese goods under the pretext of "fentanyl control." China retaliated by levying a 15% tariff on U.S.-origin corn, wheat, and other agricultural products, and a 10% tariff on sorghum and soybeans effective March 10. This move aimed to safeguard national interests and counterbalance the impact of U.S. unilateral tariffs on Chinese industries.
