The uncertain future of two U.S. border towns that thrived off trade

At the country’s busiest border crossing for trade, in Laredo, Texas, the lines of semitrucks stretch for miles. The vehicles, which ferry goods and materials across international bridges between Mexican factories and U.S. consumers, drive nearly the entire economy in this southern border city of 257,000.

Some 1,400 miles north, similar dynamics are at play in Detroit, at the nation’s busiest trade crossing with Canada, where the auto parts that drive Motor City travel back and forth between U.S. and Canadian plants.

Laredo and Detroit, perched on the borders of the U.S.’s biggest trading partners, are on the front lines of the nation’s post-Covid-19 trade economy. That economic order is likely to be disrupted by President-elect Donald Trump, who has pledged to place 25% tariffs on Canada and Mexico on the first day he takes office. This week, Trump ratcheted up the rhetoric, suggesting that steep tariffs on Canada would force it to submit to annexation by the U.S.

Trump, partly because of his own efforts to remake trade in his first term, enters a vastly different trade economy from the one he left in 2021.

In the past two years, Mexico has become the largest exporter of goods to the U.S., sending merchandise worth roughly $480 billion in 2023. China, which was the top exporter during Trump’s first term, has fallen from providing some 21% of the nation’s imported goods in 2018 to around 13% now.

The post-Covid uptick in nearshoring, alongside other factors, has helped transform Laredo, long a major South Texas port, into a heavyweight in global trade. Detroit, meanwhile, is expanding its already brisk automotive trade with Canada as new electric-vehicle and battery plants crop up on both sides of the Detroit River.

Hundreds of trucks move daily through a single 480,000-square-foot warehouse north of Laredo. Glass and aluminum go into Mexico; bottles of Modelo and Corona come back. Car batteries and other automotive parts go south; cars come north. Clothing, construction, railroad and medical supplies fill shipments.

“It’s everything you can think of: toothpaste, mops, dryers, TVs,” said Ermilo Richer, owner of the Richer logistics, warehousing and customs business.

Richer, who voted for Trump, said he sees Trump’s tariff threats as a kind of negotiating tactic. He said Trump is too smart to take a hatchet to the economy of Laredo, let alone consumers across the country, who would almost certainly see prices jump as a result of tariffs.
