Latin America's two largest economies spent the first half of 2026 living under opposite versions of U.S. trade policy. Mexican goods keep crossing the border mostly duty-free, riding on a treaty built for exactly this moment. Brazilian goods are absorbing two separate country-specific tariffs at once — and unlike almost every other major U.S. trading partner, Brazil's overall rate never really came back down.
The Ruling That Reset the Board
Everything traces to one Friday. On February 20, 2026, the Supreme Court ruled 6–3 that the International Emergency Economic Powers Act does not give a president the power to impose tariffs, striking down the global "reciprocal" duties that had defined trade policy since 2025. Chief Justice Roberts wrote the majority opinion; Thomas, Alito, and Kavanaugh dissented.
That ruling didn't just erase the 10% global baseline tariff. It also wiped out a separate, harsher measure Washington had aimed squarely at Brazil the previous summer: a 40% country-specific surcharge that the administration tied directly to Brazil's criminal prosecution of former President Jair Bolsonaro and to orders that Brazilian courts issued against American social-media platforms. It's worth being precise here: that 40% Brazil-only penalty was never part of the "reciprocal" tariff program that hit every country — it was its own political and legal action, layered on top of the reciprocal baseline. Both fell in the same ruling because both relied on IEEPA, but they weren't the same tariff.
Brazil Gets Swept Into the Global Surcharge — Then Singled Out Again
Within hours of the ruling, the White House pivoted to Section 122 of the Trade Act of 1974, a statute that lets a president impose a temporary import surcharge — up to 15%, for no more than 150 days — without asking Congress. Brazil was covered by this new global tool just like nearly every other country: the surcharge opened at 12:01 a.m. on February 24 at 10%, was raised to 15% within days, and applied to Brazilian imports the same as it applied to goods from dozens of other economies not shielded by a trade pact.
That 150-day clock was always going to run out, and it did — Section 122 expired at 12:01 a.m. on July 24, 2026, 150 days to the minute after it began. But two days before that clock ran out, Brazil got hit with something Section 122 never applied to anyone else in the same way: a finalized, country-specific 25% tariff under Section 301, targeting Brazil alone, effective July 22.
A Second Tariff Lands the Same Week the First One Expires
Section 301 gave the administration a tool with no built-in expiration date, and it used it twice against Brazil in the same week. First, USTR finalized a 25% tariff on nearly all Brazilian goods, the product of a year-long, Brazil-specific investigation, effective July 22. Then, on July 24 — the exact moment Section 122 expired — a separate, broader Section 301 action covering roughly 60 economies took effect, imposing a 10% or 12.5% duty tied to forced-labor enforcement. Brazil sits on that list too, at the 12.5% rate.
That's the detail that gets lost if you read the two Section 301 actions as sequential rather than layered: Brazil isn't just facing the country-specific 25% tariff instead of the global forced-labor duty. It's facing both, which is exactly what Brazil's own WTO complaint, filed July 27, argues — the filing challenges "an additional ad valorem duty of 25 per cent... as a result of a Section 301 investigation and an additional ad valorem duty of 12.5 per cent... as a result of another Section 301 investigation focused on allegations related to forced labour."
What USTR Says Brazil Did Wrong
USTR's case against Brazil reads less like a routine trade dispute and more like a catalog of political grievances. The investigation pointed to Brazilian court orders directing platforms including X, Meta, and Google to remove political content and freeze accounts belonging to U.S. residents, alongside complaints about preferential tariffs Brazil extends to other countries, weak intellectual-property enforcement, and barriers facing U.S. ethanol exporters. The fight has bled into Brazil's own October presidential race: President Luiz Inácio Lula da Silva has accused Senator Flávio Bolsonaro — son of the former president and a declared 2026 candidate himself — of encouraging Washington to move forward with the tariffs after a trip to meet U.S. officials, an allegation the senator denies.
The Real Numbers — And Where the Public Record Gets Misquoted
This is where a lot of commentary on Brazil's tariff situation goes wrong, so it's worth being exact. According to Global Trade Alert's analysis of the final order, Brazil's trade-weighted U.S. tariff stood at 11.0% before July 22. It jumped to 17.5% once the 25% Brazil-specific duty stacked on top of the outgoing Section 122 surcharge. Critically, when Section 122 lapsed on July 24, the rate did not fall back toward its old baseline — it held at roughly 17.7%, because the forced-labor Section 301 duty replaced Section 122's contribution almost point-for-point. Brazil's implied annual duty bill moves from about $4.4 billion to roughly $7.0 billion under the final order.
Washington did carve out real exemptions: coffee, beef, orange juice, iron ore, aircraft parts, and energy products are among more than 2,000 exempted product categories. But footwear, sugar, wood products, ethanol, and machinery remain fully exposed. Even the exemptions drew domestic pushback in the U.S. — sparing Brazilian beef prompted U.S. Cattlemen's Association president Justin Tupper to say the decision "sends exactly the wrong message" to producers and packers alike.
Mexico's Very Different Year
Mexico's experience with this same 12 months looks almost inverted. As of May 2026, 83.8% of combined U.S. imports from Canada and Mexico entered duty-free by qualifying under USMCA's rules of origin — a figure that describes the two USMCA partners together, not Mexico in isolation, though Mexico is the larger share of that trade. The July 24 forced-labor Section 301 tariff that hit Brazil at 12.5% doesn't touch USMCA-qualifying Mexican goods at all; they're explicitly exempted.
J.P. Morgan Private Bank puts a number on the gap this creates: as of the end of 2025, USMCA members carried an average effective U.S. tariff of just 3.8%, against 24.1% for China, India, and Indonesia — concluding that USMCA members remain "structurally favored relative to other regions." That protection has limits: Mexican autos, steel, aluminum, and copper still face separate 25-50% sectoral tariffs no matter their USMCA status. But on the broad measure that matters for most exporters, Mexico is paying roughly a fifth of what Brazil is paying.
Why This Matters Beyond Trade Ministries
The gap shows up in more than government spreadsheets. Latino-owned firms are the fastest-growing exporter segment in the U.S. economy; one industry account puts their 2022 footprint at more than 7 million employees and over $3 trillion in combined revenue — though that figure comes from a 2023 opinion piece rather than a government dataset, so it's worth treating as directional rather than precise. Separately, Census Bureau researchers have found that Hispanic-owned exporting firms have historically sent a far larger share of their sales to Latin American partners than non-minority-owned exporters do. That structural tilt means coffee roasters, footwear distributors, and food importers sourcing from Brazil are absorbing costs that competitors buying from USMCA-qualifying Mexican factories largely avoid.
Nothing About This Is Settled
Brazil isn't waiting on the sidelines. It has already filed at the World Trade Organization, requesting dispute consultations on July 27 that challenge both the 25% and 12.5% duties as inconsistent with WTO rules. In Washington, Senator Ron Wyden introduced the Congressional Trade Powers Reform Act on July 22 — legislation that would go further than just closing the Section 122 loophole, aiming to require congressional approval before future tariffs under Section 301, 201, or 232 as well. And USMCA itself is now in a formal joint review after Washington declined to renew the pact outright this summer, even though the underlying agreement remains in force.
For now, the asymmetry holds: Mexico's trade pact is doing precisely the job it was designed to do, and Brazil is paying — literally — for a dispute that has as much to do with politics as it does with trade.
