China has import quotas of 9.64 million tons for wheat and 7.2 million tons for corn at a 1% tariff, with imports above quota facing 65% duties. Chinese customs data shows it bought only $5 million of U.S. corn in 2025, down from $561.5 million a year earlier, with shipments stalling after June.
Chinese purchases of U.S. corn have nearly disappeared, removing a major export outlet and weighing on U.S. corn export demand and prices.
