Mexico Truckers’ Nationwide Strike Hits Key Freight Corridors, Raising New Risks for U.S.-Mexico Supply Chains

A nationwide strike by Mexican truckers and agricultural groups began Monday, April 6, with planned blockades across multiple states and warnings of an open-ended stoppage. For North American shippers, the immediate issue is not only the protest itself but where it lands: on the road network that feeds the biggest U.S.-Mexico truck gateways at a moment when customs and tariff pressures were already rising.

The strike was called by the Asociación Nacional de Transportistas (ANTAC) and the Frente Nacional por el Rescate del Campo Mexicano (FNRCM). In reporting published early April 6, El País said the groups had confirmed an “indefinite” protest in 20 states, citing highway insecurity, extortion, weak financing support, and agricultural-policy grievances. The same report said Mexico’s Interior Ministry argued there were no current grounds for the action and noted that larger industry groups, including CONCAMIN and CANACAR, had distanced themselves from the blockade strategy in favor of dialogue.

What is happening on April 6

Available reporting as of Monday indicates a mix of confirmed disruptions and planned blockades, rather than a fully uniform national shutdown. Pre-strike alerts pointed to coordinated actions on highways feeding Mexico City, Querétaro, Michoacán, Sinaloa and other central and western corridors, with organizers framing the action as a national stoppage over road insecurity and operating conditions.

The most operationally important point for freight managers is that the protest is not just symbolic. Organizers have explicitly targeted highways and strategic choke points, and their published demands include eliminating alleged extortion checkpoints in San Roberto, Nuevo León; San Blas, Nayarit; La Venta, Tabasco; and San Luis Río Colorado, Sonora, while also demanding stronger National Guard patrol coverage and a specialized prosecutor for cargo-crime cases. El País, April 6

That matters because even partial blockades in a handful of trunk corridors can cascade quickly into missed export slots, delayed drayage, trailer shortages, and northbound queue spillover at the border.

Which freight corridors are most exposed

Early reporting and pre-action advisories point to disruption risk on routes tied to some of Mexico’s most important industrial basins:

• Nuevo León / Monterrey region, particularly corridors that feed Laredo/Nuevo Laredo
• Chihuahua / Juárez region, which supports traffic into Ysleta-Zaragoza and other El Paso-area crossings
• Baja California, especially corridors feeding Otay Mesa
• Tamaulipas and Reynosa/Pharr-McAllen lanes
• Sonora / Nogales connections
• Central Mexico corridors linking the Bajío manufacturing cluster to the border

Not every crossing appears equally affected. As of publication, the better-supported reporting shows a broad protest footprint, but not clear evidence that every major border gateway is fully shut. That distinction is important: the operational risk may be asymmetric, with some gateways still processing while others experience feeder-road delays, sporadic closures, or severe queueing.

Why cross-border supply chains are vulnerable

The U.S.-Mexico land network is too concentrated to absorb major road friction gracefully. According to the U.S. Bureau of Transportation Statistics’ 2025 annual transborder freight report, Laredo remains the dominant truck gateway with Mexico, handling 38.8% of all inbound trucks from Mexico in 2025. BTS also notes that Laredo, Ysleta and Otay Mesa are the top truck ports with Mexico. BTS Border Crossing Data Annual Release: 2025; BTS Transborder Freight Data Annual Report: 2025

The 2024 BTS truck-freight tables underscore that concentration by trade value. Truck freight through Laredo totaled about $282.0 billion in 2024, followed by Ysleta/El Paso at about $83.4 billion, Otay Mesa at about $60.9 billion, Hidalgo at about $42.6 billion, Santa Teresa at about $38.8 billion, and Nogales at about $25.0 billion.

That concentration is especially relevant for sectors such as automotive, industrial machinery, electronics, appliances, and metals, where freight often moves in tightly sequenced truckload, cross-dock, and border-dray patterns. BTS has separately highlighted that goods in HS Chapters 84 and 85—machinery, mechanical appliances, electrical equipment and related components—are heavily concentrated through southern truck gateways, with Laredo alone handling 28.4% of the dollar value in those commodity groups.

What the disruption means operationally

For logistics teams, the first-order effects are straightforward:

Missed pickups and slipped linehaul schedules

Carriers may miss factory pickup windows in Mexico even if the border itself remains technically open. A truck that cannot clear a blocked toll road or approach route can still fail the shipment.

Border-queue spillover

When feeder highways back up, arrival patterns at ports of entry become erratic. That can create bunching, longer wait times, and underutilized appointments followed by sudden surges. CBP’s border-wait system remains the key public reference point for commercial crossing conditions at U.S. ports, but it does not capture the full picture of road congestion deeper inside Mexico.

Customs-timing complications

Customs entries, broker staffing, and pre-clearance sequencing can all be disrupted when trucks miss dispatch windows. That is particularly disruptive for high-frequency freight programs where plant receipts are timed to production shifts.

Trailer, chassis, and yard imbalances

If northbound equipment is delayed in Mexico, yards on the U.S. side can feel the shortage quickly. Conversely, staged trailers already north of the border may sit longer than planned waiting for return cycles.

Detention, demurrage, and plant-side shortage risk

A one-day protest can become a multi-day inventory problem if it causes cascading appointment failures, yard congestion, or missed feeder connections into rail ramps and distribution centers.

The strike lands on top of a worsening trade-policy backdrop

The April 6 trucking disruption is hitting while cross-border traders are already managing a more unstable customs and tariff environment.

First, recent FreightWaves Borderlands reporting said tariff pressure was already showing up in North American customs data, reflecting how importers were adjusting entry behavior and classification decisions amid policy volatility. That matters because when customs behavior is already shifting, a physical trucking shock is more likely to produce documentation errors, clearance timing issues, and freight reprioritization.

Second, the duty rewrite flagged in earlier reporting has now moved from expectation to official action. On April 2, 2026, the White House issued a proclamation titled “Strengthening Actions Taken to Adjust Imports of Aluminum, Steel, and Copper Into the United States.” The change takes effect April 6, 2026 and states that the additional Section 232 duty on covered aluminum, steel and copper articles and derivative articles will apply to the full customs value of the imported product, regardless of metal content. White House proclamation, April 2

For cross-border industrial freight, that timing is awkward. Metals-related products, fabricated components, machinery, enclosures, assemblies and industrial parts already facing reclassification and landed-cost recalculation now also face a same-day disruption in Mexican trucking. In practice, that can force shippers to choose between delaying freight for cost review or expediting under impaired network conditions.

Government and industry response

As of Monday, Mexico’s federal government had pushed back publicly on the rationale for the strike and said dialogue channels remained open. El País reported that the Interior Ministry cited grain-support spending and security actions already taken, while also emphasizing that many industry organizations had chosen not to mobilize. El País, April 6

That split inside the transport sector is important. If large national carrier groups and industrial chambers remain outside the blockade effort, the result may be selective paralysis rather than total stoppage—still serious for time-sensitive freight, but potentially navigable through alternate dispatching, preload holds, and border-gateway selection.

Public U.S. border agencies have not, as of publication, issued a broad systemwide advisory specific to the strike. That means operators should watch local bridge authorities, customs brokers, carrier bulletins and the CBP wait-time system closely through the day rather than assuming uniform conditions at all ports.

What to watch over the next 24 to 72 hours

1. Whether key feeder corridors into Laredo and Reynosa remain passable

Even short-duration blockades on Monterrey-facing corridors can have outsized consequences because of how much truck freight converges on South Texas.

2. Whether border disruption spreads from highways to bridge access roads

A protest that begins inland can become more severe if demonstrators shift toward toll plazas, customs approach lanes, or urban connectors near ports of entry.

3. Whether OEMs and tier suppliers start rescheduling production-support freight

Automotive and industrial manufacturers with dense Mexico programs are usually the first to escalate controls on premium freight, milk runs and launch-critical parts.

4. Whether brokers and carriers begin rerouting by gateway

Traffic can be rebalanced toward Otay Mesa, Santa Teresa, Nogales, Brownsville, Eagle Pass, or Pharr/Hidalgo where lane structure, distance and customer geography permit—but only up to a point.

5. Whether the strike proves truly indefinite

A one-day action is disruptive; a multi-day blockade begins to affect inventory positioning, export bookings, and labor planning across both sides of the border.

Bottom line

The April 6 strike is best understood as a stacked risk event for North American industry: first, a concentrated trucking disruption across parts of Mexico; second, a customs-and-tariff environment already under strain; and third, a border network where a small number of gateways carry an outsized share of industrial freight.

For manufacturers, distributors and project cargo planners with Mexico exposure, the practical challenge is less about headline politics than execution: which corridors are moving, which crossings are absorbing overflow, how long the stoppage lasts, and which shipments cannot wait.

For CAP Logistics readers, the immediate priority is disciplined exception management: verify lane-level conditions before dispatch, confirm broker and carrier cutoffs, identify freight that is truly production-critical, and be prepared to rebalance crossings or hold preload until corridor conditions stabilize.
