Mexico imposes 50% tariff on white corn imports amid trade dispute with U.S. and Canada

Mexico published a measure imposing a 50% tariff on white corn imports, effective until the end of the year. The measure comes amid a trade dispute with the US and Canada over genetically modified corn.

WHY IT MATTERS

The tariff changes the flow of white corn into Mexico and adds to trade uncertainty around corn. Its direct effect on US yellow corn exports is limited, so the price impact is mixed.
