Sorghum was one of the first casualties of the U.S.-China trade war. China launched an anti-dumping probe into sorghum in February in response to U.S. tariffs on solar panels and washing machines.

Chinese buyers have bought no significant volumes since then, according to U.S. Department of Agriculture data. In 2017, they bought about $839 million of U.S. sorghum, most of which was shipped in the months after the autumn harvest.

Both sides were frustrated by the impasse.

“I want to sell and they want to buy,” one trader said.
