Trump Mexico Tariff Threat Over Caravan Explained

President Trump says tariffs on Mexican goods will be doubled unless Mexico stops a caravan moving through Chiapas. Mexico’s president says no caravan has reached the U.S. border in almost two years, and the legal basis for the threat is unclear.

President Trump threatened on Thursday, Nov. 12, to “immediately” double tariffs on imports from Mexico unless the Mexican government halts the migrant caravan that left Tapachula, near the Guatemala border, on Tuesday. In a Truth Social post reported by Bloomberg, Fox News, Forbes and FreightWaves, Trump called the caravans an invasion, wrote that the migrants “will not be accepted,” and said Border Patrol, ICE and both Texas Gov. Greg Abbott and Governor-elect Gina Hinojosa had been informed. “MEXICO MUST STOP THEM, NOW,” he wrote, according to Bloomberg. The post set no deadline and did not say which tariffs would be doubled.

Hours later, Mexican President Claudia Sheinbaum pushed back at her morning press conference. “Not a single migrant caravan has reached the north,” she said, according to the Associated Press, referring to the period since Trump took office in January 2025. She ruled out using force to break up the groups. As reported earlier, the caravan’s participants set out hoping that the new Democratic majority in Congress would change border policy, a hope the law does not support.

What exactly did Trump threaten?

The post threatens a trade penalty, not a new immigration rule. It does not change who can seek asylum, how people are processed at ports of entry, or what happens to anyone who crosses. Several points remain open:

Which tariffs: FreightWaves reported that the post did not specify which duties would double, whether goods that qualify under the U.S.-Mexico-Canada Agreement (USMCA) would stay exempt, or when any increase would start.
What applies now: the AP reported that Mexico is seeking relief from a 10% tariff on goods that do not qualify under USMCA, a 25% duty on medium- and heavy-duty trucks and a 50% tariff on steel and aluminum. Other outlets have published different figures, so the baseline that would be “doubled” is itself unsettled.
Market reaction: Bloomberg reported that the peso slipped after the post and that Mexico’s foreign and economy ministries did not immediately respond.

Can the President double tariffs on Mexico?

That is the largest legal question. On Feb. 20, 2026, the Supreme Court ruled 6-3 that the tariffs Trump had imposed under an emergency powers law were unlawful, holding that the taxing power belongs to Congress, the AP reported at the time. Administration officials said then that they would rely on other trade statutes, which the AP noted carry more limits on how fast and how far tariffs can go. Bloomberg reported Thursday that it was not immediately clear what authority Trump would use to double duties on Mexican goods.

Any increase would land in the middle of an already strained trade relationship. Forbes and FreightWaves reported that the United States declined in July to extend USMCA beyond 2036, and that talks over steel and aluminum duties have stalled. FreightWaves noted that Mexico is the largest U.S. trading partner, with about $96 billion in two-way trade in September alone. If a tariff increase is actually ordered, it would likely be challenged, and the authority it cites will determine how quickly a court could act.

How big is the caravan, and where is it now?

Accounts differ. Reuters put the group at more than 1,000, a Chiapas government source cited by Al Jazeera estimated about 1,500, and EFE reported about 2,000. The AP, by contrast, reported Thursday that about 600 migrants in Chiapas had largely dispersed after being told that reaching the United States would be very difficult, and that Mexican officials were urging several hundred Hondurans to return home. It is not yet clear whether these reports describe the same group.

History suggests caution about the threat level. AFP, cited by Al Jazeera, described this as the third caravan since September; the first two broke up in Chiapas, and their members received temporary permits to stay in Mexico. On Tuesday, Mexican National Guard, immigration and state police officers stopped a separate group of about 100 people, detaining about 40, according to AFP. The caravan’s first goal is Mexico City, more than 1,000 kilometers away.

What it means for migrants, families and employers

Caravan participants: the border rules they would face are unchanged. The January 2025 proclamation suspending entry at the southern border under section 212(f) remains in place, as do expedited removal and detention, as explained in the earlier article. A tariff fight between governments does not create any new route into the United States.
Organizers and supporters: the State Department has already restricted visas for more than 15 alleged caravan organizers and warned that participants could lose visas. People with pending U.S. visa cases should avoid any role in organizing or financing a caravan.
U.S. employers and importers: the immediate exposure is commercial, not immigration-related. Businesses that rely on Mexican inputs, including trucks, steel and auto parts, should track whether a formal tariff order follows and which goods it covers.

Quick answers

Did Trump actually raise tariffs on Mexico?
Not as of Thursday afternoon. He announced a threat on social media; no tariff order specifying rates, goods or a start date has been published.

Has the caravan reached the U.S. border?
No. It left Tapachula on Tuesday and is still in southern Mexico, and Sheinbaum says no caravan has reached the northern border since January 2025.

Will Mexico stop the caravan?
Sheinbaum ruled out force and said authorities are accompanying migrants with information and humanitarian aid. Mexican officers did detain part of a smaller group on Tuesday.

Does the new Congress change any of this?
Not directly. Border processing and tariff threats both run through the executive branch, and the new Congress is not seated until Jan. 3, 2027.
