U.S. Tariffs Slam Mexican Exports Driving Truck Traffic Down 20 Percent and Threatening North American Trade Flows

Listeners, welcome to Mexico Tariff News and Tracker. Today’s headline topic is the rapid escalation of tariffs between the United States and Mexico, and its impact on trade, industry, and economic prospects as of October 17, 2025. 2025 has seen a steep hike in effective tariff rates on Mexican exports to the U.S., with the Dallas Federal Reserve noting an increase to 10.6 percent compared to just 1.6 percent last year. This spike comes amid continued trade policy uncertainty under President Donald Trump, with roughly 80 percent of Mexico’s exports still bound for the U.S. and key sectors like automotive, electronics, and agriculture deeply affected. Truck freight traffic, a crucial barometer of cross-border commerce, has taken a direct hit. According to Miguel Ángel Martínez Millán, president of the National Chamber of Freight Transport, Trump's tariffs led to more than a 20 percent drop in truck freight traffic from Mexico to the U.S. in 2025. That decline reflects sharply reduced export and import volumes for crucial goods such as vehicles, auto parts, steel, and aluminum—especially where products fail to meet tightened country-of-origin rules. Martínez Millán calls the impact of these tariffs 'very worrying' as cancellations of operator licenses and visas further compound the shipping uncertainty, although the exact numbers on affected truck drivers remain undetermined. On the policy front, the White House has confirmed a new headline tariff—effective November 1st, a 25 percent tariff will be imposed on all imported medium- and heavy-duty trucks, including those built in Mexico. Administration officials claim this move is necessary for national security, but the commercial vehicle sector and automakers warn it will further inflate costs for manufacturers and disrupt North American supply chains. Under the US-Mexico-Canada Agreement, some trucks can still qualify for zero tariffs if at least 64 percent of their content comes from North America, but the threshold is set to rise to 70 percent in the near future. This rule keeps manufacturers on edge as they adjust sourcing and production to avoid penalties. Broader trade friction is also evident in S&P Global’s latest estimate: Trump’s tariffs are projected to cost global businesses around $1.2 trillion in 2025, with nearly two-thirds of that burden falling on North America and its manufacturing partners. All this comes at a time of economic weakness for Mexico. The country’s economy did grow by a surprising 1.8 percent in the first half of the year, thanks largely to exports that beat expectations, possibly as firms tried to beat the tariff clock. However, growth is now forecast to slow to 0.7 percent for the remainder of 2025. The uncertain USMCA renegotiations and escalating tariffs push Mexican businesses and the broader economy to a state of vigilance and adaptation.
