As the U.S. and Mexico remain locked in trade talks, Mexican automakers have a complaint with the current agreement: They¡¯re paying some higher tariff rates than competitors in South Korea and Japan.

As part of discussions to review the U.S.-Mexico-Canada free trade agreement, Mexican government officials have shown evidence that the average tariff on Mexican auto exports is almost 19%, higher than the 15% levies on some vehicles imported from South Korea or Japan.

U.S. Trade Rep.?Jamieson Greer and his staff have told their Mexican counterparts that they understand Mexican cars should be in a better position than those from other countries and that they¡¯re exploring alternatives, the people said. They haven¡¯t necessarily agreed with the Mexican negotiators¡¯ data though, one person said.
