The 2026 USMCA Review
A Structural Test for Mexico

← Back to Latin America News

The first joint review of the US-Mexico-Canada Agreement (USMCA) finally begins in July. Bilateral talks are already under way: the United States and Mexico held rounds on economic security and rules of origin in May, on agriculture and a "level playing field" in June, and have set "securing US interests" for July. A renegotiation touching the core of North American manufacturing—autos, farm goods, and energy—is beginning to rattle Mexico's heavily export-dependent economy.

How a Routine Checkup Became Something Else

The USMCA, in force since 2020, contains a clause for a joint review every six years. It was first expected to be a routine confirmation of the rules. The return of the Trump administration upended that assumption. Issues that sit well outside the usual scope of trade—curbing migration and drug smuggling, blocking the inflow of Chinese capital into Mexico—have been brought to the table. The condition that the agreement lapses in 2036 if no deal is reached lends real urgency.

On June 2, the Office of the US Trade Representative (USTR) applied pressure through a separate channel as well. Citing inadequate controls on imports of goods made with forced labor, it proposed additional tariffs of 10 to 12.5 percent on 60 countries under Section 301 of trade law, placing Mexico and Canada in the 10 percent band. The review and these tariffs are legally distinct, but politically they read as linked moves (USTR).

June's Agenda: Agriculture and a "Level Playing Field"

In the June round, agriculture turned on limits to US corn's access to the Mexican market—Mexico has sought to restrict imports of genetically modified corn. Export conditions for Mexican avocados and sugar, and the gap in farm subsidies between the two countries, were also on the table. A "level playing field" is a concept that reexamines Mexico's competitive advantage over the US across a wide range of areas: wages, labor conditions, environmental standards, and subsidies.

If talks advance within that frame, the very basis of Mexico's cost advantage as a manufacturing location becomes the point of contention.

A Crossroads for the Auto Supply Chain

In autos and parts, which make up roughly 30 percent of Mexico's exports to the US, the current rule of origin requiring 75 percent or more North American content is in question. Behind this lies the move by Chinese parts makers to set up plants in Mexico and export to the US as certified North American goods—so-called "China-shoring." In response, the US is expected to push for tighter conditions excluding Chinese-made parts.

According to reports, candidates on the agenda include tightening the rules of origin and excluding Chinese components from the content calculation. If realized, several assembly plants operating inside Mexico would be forced to reconsider their sourcing (CSIS).

"We'll Wait Until the Terms Are Set"

Companies waiting to judge until the review's direction is clear are already braking foreign investment into Mexico. If a USMCA renewal becomes certain, manufacturing investment may accelerate its return to Mexico. If talks stall, a shift to Canada or other candidate sites could pick up instead. After the formal review opens in July, markets are hoping some direction will emerge within the year (Baker Institute).

My Perspective

Trade can look like a distant world, but to me it does not feel that way. Many orthotic, prosthetic, and medical devices rest on chains of parts and assembly that span several countries. When rules of origin tighten and a part has to be sourced elsewhere, final prices and lead times shift, little by little. The wait and the cost to obtain a single brace bear directly on the quality of life of the person who needs it. When a North American trade negotiation circles back to touch the price of a tool that reaches the floor of a clinic, I want to keep the imagination to see that.

There is something else I came to feel during my time in Costa Rica and across Latin America: the rise and fall of a regional economy maps straight onto the strength of its social safety net. If Mexico's exports and investment thin out, tax revenue and jobs feel it, and the burden ultimately falls on those who most need support. I want to follow this review not only as "a story about auto tariffs," but with an eye on how the foundations of everyday life for people in the region may change.

Glossary

USMCA: the US-Mexico-Canada Agreement, in force since 2020. Rules of origin: conditions, such as a minimum share of in-region production, that a product must meet to qualify for the deal's preferences. Section 301: a basis in US trade law that lets the US take unilateral measures such as tariffs against unfair trade practices. China-shoring: an informal term for Chinese firms relocating production to Mexico and elsewhere to export as in-region goods.

A single clause in a trade deal quietly shapes everything from where factories sit to which seeds farmers plant, and even the price of the tools that reach a clinic.
