Cross Border Trucking from Southern California

What cross border trucking involves

Cross border trucking is international trucking: the movement of freight by truck between the United States and Mexico or Canada, with the shipment reported to customs in both countries before it reaches the border. A domestic load needs a truck, a driver and a delivery appointment. A cross-border load also needs electronic manifests, an export record, an import declaration in the destination country and, usually, a different carrier on each side of the line.

Our model is straightforward. We pick up from the Port of Long Beach, the Port of Los Angeles or any Southern California shipper, handle any transloading or consolidation in Long Beach, and move the freight to the handoff point. From there, authorized partner carriers take it across the border and on to the consignee. Your customs broker files the customs documents in each country, and we coordinate timing and data with that broker.

This page explains how the pieces fit together. The Mexico cross-border page and Canada cross-border page cover the country-specific documents, systems and crossing realities in detail.

Cross-border trucking by country

Each country has its own customs systems, carrier rules and documents. Choose a destination for the specifics.

The two borders run on different systems and different carrier models, and the differences drive how a shipment is planned.

Who does what on a cross-border shipment?

A cross-border shipment succeeds when four parties share the same information early: the shipper, the importer of record in the destination country, the customs brokers on each side, and the carriers. Most delays come from one of them working off a different invoice, a different weight or a different pickup date than the others.

The shipper or exporter supplies the commercial invoice, packing list and, if a USMCA preference will be claimed, the certification of origin data. The U.S. exporter or its agent files Electronic Export Information when it is required. The importer of record in Mexico or Canada appoints the destination customs broker and pays any duties and taxes there.

The customs brokers prepare and transmit the import declarations, and on northbound freight the U.S. customs broker files the U.S. entry. The carriers transmit their electronic manifests and must not depart for the border until the broker confirms the shipment is ready.

Our role is the Southern California side and the coordination between them. We pull the container or pick up the freight, unload and reload it if needed, confirm piece counts and weights, share the paperwork with the broker and the partner carrier, and tender the load for the crossing only when the broker signals it is ready. We do not file customs entries or declarations; a licensed customs broker does that. If you need one, our page for customs brokers explains how we work with them day to day.

How cross border trucking works from Southern California

Southbound and northbound shipments share the same structure. Here is the southbound sequence for freight leaving the Los Angeles and Long Beach area.

1. 01
   Quote and route

   Send origin, destination city and country, commodity, piece count, weight, dimensions and whether the freight is full truckload or partial. We confirm the handoff point and the partner carrier, and you confirm who the customs brokers will be on each side.

2. 02
   Paperwork goes to the brokers first

   The commercial invoice, packing list and any USMCA certification go to the destination broker before the truck moves. For Mexico, the Mexican broker needs them to build the pedimento; for Canada, the broker needs them for the release request.

3. 03
   Pickup, transload or consolidation in Long Beach

   We pick up at the shipper or pull an ocean container from the port. If the freight arrived in a container, we can transload it into a 53' trailer or consolidate several shipments so the cross-border truck carries one clean, accurately counted load.

4. 04
   U.S. export filing

   When Electronic Export Information is required, the filer transmits it in the Automated Export System and gives the carrier the filing citation (the ITN) at least one hour before the truck reaches the border.

5. 05
   Line-haul to the handoff

   We move the freight to the partner carrier. For Mexico, that is the San Diego border area near Otay Mesa; for Canada, the partner carrier takes the load north toward the crossing it uses.

6. 06
   Manifests and release

   The crossing carrier transmits its electronic manifest, and the broker links the release or pedimento to it. The truck goes to the border only after the broker confirms the shipment is ready to clear.

7. 07
   Crossing and final delivery

   The partner carrier crosses, clears inspection if selected, and delivers. We keep you updated on status from pickup to handoff and relay the partner carrier's updates after the crossing.

Why cross border freight changes carriers at the border

Cabotage rules are the main reason a single truck rarely makes the whole trip on the Mexico border. Cabotage means moving goods between two points inside a country with a foreign carrier or driver, and the United States, Mexico and Canada all restrict it.

In the U.S., Canadian and Mexican drivers generally may not haul domestic loads; CBP's guidance is that the driver may only take goods loaded in the United States to Canada or Mexico. Enforcement on the southern border has tightened in 2026, with FMCSA inspection records now shared with CBP. In Canada, the CBSA allows U.S.-based trucks to carry only goods that are part of a shipment entering or leaving Canada; picking up and delivering within Canada is reserved for Canadian carriers except in narrow cases.

On the Mexico border, carriers from each country generally operate only within a narrow zone on the other side, so border transfer carriers (also called drayage carriers) shuttle trailers across. That is why a typical shipment to Mexico involves a U.S. carrier, a transfer carrier and a Mexican carrier. On the Canada border, carriers commonly run through to destination when they hold the needed authority and the driver is admissible.

Documents for cross border shipping

This checklist covers the documents that most often hold a truck at the border. Your brokers may require more for regulated goods.

Import cargo bound for Mexico or Canada: the in-bond option

Foreign cargo that lands at Los Angeles or Long Beach but is sold to a customer in Mexico or Canada does not have to enter U.S. commerce. It can move under a CBP in-bond, which defers U.S. formal entry and duties while the goods travel to the port of exportation.

The two in-bond types used for this are Transportation and Exportation (T&E), which moves the goods to another U.S. port for export, and Immediate Exportation (IE), which exports them from the port of arrival. Under 19 CFR 18.1, in-bond merchandise must reach the port of exportation within 30 days, and once there it generally must leave within 15 days.

We hold bonded carrier authority and operate a CBP-bonded warehouse in Long Beach, so we can pull the container under bond with bonded drayage, hold it in bonded warehousing if timing requires, and coordinate the in-bond type with your broker. Every carrier that handles the freight under the bond must be a bonded carrier. Our guide to in-bond shipments explains the mechanics.

Common cross border trucking mistakes

These are the problems that most often turn a planned crossing into a truck parked in a border lot.

• Dispatching before the broker is ready. A truck at the border without a matching pedimento or release request waits, and waiting time at the border is billed.
• Invoice and freight that do not match. Piece counts, weights or descriptions that differ from the manifest trigger holds and inspections. We count and weigh during transloading so the numbers match.
• Vague product descriptions. 'Parts' or 'merchandise' is not enough for a pedimento or a Canadian release. Use descriptions that support the tariff classification.
• Assuming USMCA applies automatically. The preference must be claimed and supported by a certification of origin; goods made from non-qualifying materials may not qualify.
• Forgetting the U.S. export filing. Southbound freight to Mexico over $2,500 per Schedule B line needs EEI, and the carrier needs the filing citation before the crossing.
• No importer of record lined up. The receiving company must be set up to import in its country, or the freight cannot be cleared there.
• Mixing domestic stops into a cross-border load. Cabotage rules can bar a foreign driver from a domestic pickup or delivery, so plan domestic stops on a separate move.

Truckload or LTL across the border

Full truckload is the simplest way to cross. A single shipper, a single importer and one set of documents means one manifest entry and fewer chances for a mismatch. Most of our cross-border freight moves as full truckload in 53' dry vans.

Partial and LTL freight can cross too, but every shipment on the trailer needs its own documents, and one incomplete shipment can hold the whole truck. If you ship small volumes regularly, consolidating several orders into one load in Long Beach can reduce that risk. Our FTL vs. LTL guide covers the cost tradeoff.
