Trump threatens to double Mexico tariffs over migrant caravans
Trump’s ‘doubled’ Mexico tariff has no rate, no date and a narrow legal path
On Thursday 12 November President Trump threatened to double tariffs on Mexican goods unless Mexico stops a migrant caravan walking north. “MEXICO MUST STOP THEM, NOW, and if they do not do so, the Tariffs on Mexico will be IMMEDIATELY DOUBLED,” he wrote on Truth Social, as quoted by FreightWaves.
The target is the largest trade relationship the US has. Two-way trade with Mexico was $96.34 billion in September, and Laredo, Texas, handled $38.9 billion of it, FreightWaves reported.

Our view is simple. This is leverage, not a tariff. It is aimed at getting Mexico to break up or hold back a caravan, and it is likely to end the way the last migration tariff threat did: with a Mexican enforcement gesture and no new duty. Forwarders should prepare a small group of exposed clients. They should not push the whole book into front-loading, which means rushing shipments across before a tariff hits.
What was actually said
Trump’s post opened with “Here we go again!” and tied the caravan to Republican losses in the midterm elections, according to Supply Chain Dive. FreightWaves also reported the “Here we go again!” line. He wrote that “Huge CARAVANS are forming and beginning their illegal march through Mexico,” and that “They will not be accepted!”
What the post did not say matters more to anyone filing entries. FreightWaves reported that Trump did not say which tariffs would be doubled, whether trade exemptions would remain, or when any new duties would start. No rate, no product list, no effective date.
Other officials added pressure. Border czar Tom Homan said Mexico “needs to put troops on their southern border and northern border”, Mexico News Daily reported. Homeland Security Secretary Markwayne Mullin wrote: “This illegal migrant caravan will NOT be allowed to enter our country. Full stop,” according to the same outlet.
The caravan itself is modest. More than 1,000 migrants left Tapachula, near the Guatemalan border, on Tuesday 10 November, heading first for Mexico City, Texas Public Radio reported. Reuters put the group at about 1,500 and EFE said it began with roughly 2,000, according to FreightWaves. Reuters expects the trip to Mexico City to take at least several weeks, Mexico News Daily reported.
Mexico’s president, Claudia Sheinbaum, played it down at her 12 November press conference. “Since President Trump came into office, no migrant caravan has reached the northern border,” she said, as quoted by FreightWaves. She said an earlier group that formed in Arriaga with 500 to 600 people had shrunk to fewer than 100, according to Mexico News Daily. She said the government would not use force against the migrants.
Doubled from what?
This is where the threat gets hard to price. Reporters cannot agree on what Mexico pays now.
FreightWaves lists 25% on most goods that don’t qualify under USMCA (the US-Mexico-Canada trade agreement), 0% on goods that do qualify, 25% on Mexican-made cars, and 50% on steel and aluminium. Supply Chain Dive says Mexico “is currently subject to a 10% tariff following a forced labor probe launched in March.” It also notes a separate US probe, opened in March, into manufacturing capacity policies in several countries, Mexico among them.
Those two pictures don’t match, and neither outlet sets out every legal basis. So any “from X% to Y%” headline is guesswork today. The honest answer is that “double” has no single number attached to it.
The legal route is also narrow. Texas Public Radio notes it is unclear which authority Trump would use to double tariffs after the Supreme Court rejected his emergency economic powers in February.
That leaves the sector duties. Mexico News Daily wrote: “Among the U.S. tariffs Trump could conceivably double are those that currently apply to Mexican steel, aluminum and vehicles.” Those duties sit under Section 232, a national-security trade law that is separate from the emergency powers the court rejected. Mexico is already negotiating to cut the Section 232 duties imposed last year, the same outlet reported.
In our view, that is the real exposure. A broad doubling across all Mexican goods looks legally hard. A higher rate on metals and vehicles is the one version that could plausibly be done by presidential proclamation.
What happened last time
There is a close precedent. On 30 May 2019 Trump threatened a 5% tariff on all Mexican imports over migration, rising to 25% by October, Bloomberg News reported via Transport Topics. On 7 June 2019, eight days later, he said the tariffs were “indefinitely suspended.” Mexico had agreed to expand its National Guard deployment, focusing on its southern border, and to take back asylum seekers while their US claims were processed.
That threat had a rate, a start date and a schedule. It still never took effect. This one has none of those.
The politics also point toward a deal, not a duty. Texas Public Radio reports that Democrats take control of Congress in January. Supply Chain Dive lists three pending bills that could restrict the president’s tariff powers: S. 5390 and S. 1272 in the Senate and H.R. 7557 in the House. Trump told CBS’s 60 Minutes his deportation campaign might have been “too tough” for voters, according to Texas Public Radio. That gives the White House reasons to want a quick win it can show off, which a Mexican crackdown would provide.
Two things cut the other way. The USMCA was not extended at its July review, so the wider trade talks are already tense, Texas Public Radio and FreightWaves reported. And Sheinbaum is heading to the APEC summit in China, where her economy secretary, Marcelo Ebrard, will push for closer trade and investment ties. A visible tilt toward Beijing could harden Washington’s tone.
What this means for forwarders
The freight at risk is concentrated. FreightWaves names autos, industrial equipment, electronics and metals as the sectors most dependent on cross-border trucking. Texas carries most of it. “The state handles about three-quarters of U.S.-Mexico land trade, according to Dallas Fed economist Roberto Coronado,” Texas Public Radio reported. Texas traded $301.8 billion in goods with Mexico last year, the same report said.
Here is how we would split the work this week.
Metals and auto importers. These are the clients a Section 232 move would hit first. Check that their customs bonds (the insurance that guarantees duty payment to US Customs) are big enough to cover a higher duty bill. Bond size is set on duties paid, so a sudden jump can push an importer over its limit. Review whether foreign-trade zones (fenced areas where duty is deferred until goods enter the US market) or bonded warehouses make sense for inventory already on the way.
USMCA-qualifying freight. Make sure origin paperwork is clean. FreightWaves lists qualifying goods at 0% today. If any new duty keeps that exemption, they are the safest place to be.
Everyone else. Hold off on paying for front-loading. Rushing freight into Laredo ahead of a tariff with no date can tighten truck capacity and raise spot rates for no gain. Watch for a formal notice instead. A real change would show up as a presidential proclamation and a CBP CSMS message (Customs’ system for alerting the trade), not a social media post.
Sales teams should expect calls. Shippers will ask whether to move goods now. The answer, in our view, is “not on this alone.”
Our call
We expect Mexico to make a visible move against the caravan within the next two to three weeks, as it did in 2019. That could be more troops in the south, or more migrants persuaded to stop or go home. We expect the White House to claim the result as a win.
Our prediction: no doubled tariff on Mexican goods, including the Section 232 duties on steel, aluminium and vehicles, takes effect before 31 December 2026. If a doubling is formally proclaimed, we expect it to cover only those Section 232 lines, not all Mexican imports.
