Laredo port of entry: major US land gateway to Mexico

Laredo Location

Laredo sits at 27 degrees 30 minutes north and 99 degrees 30 minutes west, in the southernmost interior of Texas, bordered on the south by Mexico across the Rio Grande. The city faces Nuevo Laredo, and several international bridges link the two into what is effectively a single cross-border metropolitan area.

• State: Texas, south-central United States. Mexico to the south, New Mexico to the west, Oklahoma to the north, Louisiana and Arkansas to the east
• Main artery: I-35 runs about 1,500 miles north from Laredo through six Midwestern states to Duluth, Minnesota; south it joins Mexican Highway 85 toward Monterrey and Mexico City
• City across the river: Nuevo Laredo, Tamaulipas, the main crossing between the northern Mexican industrial belt and the US side
• Nearby nodes: about 160 miles to San Antonio, Corpus Christi and McAllen, and about the same to Monterrey, Mexico
• Rail: US service by Union Pacific and Kansas City Southern (now part of CPKC), Mexican handoff by KCSM, with two rail bridges carrying cross-border traffic
• Airport: Laredo International Airport (code LRD), with both US and Mexican customs facilities
• Metro area: about 200,000-plus people, with industry led by cross-border trade, warehousing and distribution, brokerage and freight services, and auto parts and electronics assembly

Port of Entry Profile

In the US customs system Laredo is a land port of entry, code 2304. Its parent field office is the Laredo Field Office itself, so the city is both the execution point and the regional management location, meaning complex entries and seizure matters are handled locally rather than escalated to another city.

Having the field office in the city is a practical convenience for importers handling origin determinations, additional tariff applicability, seizures and appeals: documents do not need to be sent across state lines and can be dealt with locally. General rules on merchandise admission and rate applicability are covered in the US customs import and export policy and customs duty sections.

International Bridges

Laredo has five international bridges, three of which can carry commercial freight and two reserved for passenger vehicles and pedestrians. For freight, the usable entries are only the World Trade Bridge and the Colombia Solidarity Bridge, with rail cargo using the Laredo International Railway Bridge. The three commercial channels have separate crossing points and operating hours, and the choice depends on cargo type, time of day and port congestion.

The World Trade Bridge is the main commercial truck channel, carrying trucks only, which by design avoids the queuing that mixed passenger traffic creates. It carries one of the highest truck volumes among truck-only bridges, with a morning and an afternoon peak. The Colombia Solidarity Bridge serves as relief and backup: when the World Trade Bridge is congested or temporarily closed for maintenance, trucks divert there, which is why Laredo holds up better than ports with a single commercial bridge. The Colombia Solidarity Bridge opened on July 31, 1991, with truck lanes open until midnight on weekdays and shorter weekend hours, so weekend crossings should be planned against the 08:00-16:00 window. The Juarez-Lincoln Bridge was built in 1976 to divert truck traffic from the Gateway to the Americas Bridge and today carries only passenger vehicles and buses.

Rail Crossing Channels

Laredo's rail position between the United States and Mexico is a hub role: it is a principal international rail crossing into Mexico. Two rail bridges carry cross-border traffic, and a second span added in February 2025 converted a single-track crossing into a channel capable of simultaneous two-way crossings, the largest capacity expansion on this corridor in a decade.

A further role of the second span is to support inspection: the new bridge carries inspection and monitoring equipment, so the checking step during a crossing can be completed on one side of the bridge rather than being pushed back to the yards. For full-container cargo picked up in the northern Mexican industrial belt and moved to the US Midwest, the value of this channel lies in the rail rate differential against trucking and the fit of single-train capacity for large volumes. US-Mexico freight totaled about USD 872.8 billion in 2025, of which rail carried about USD 95 billion, or 10.9 percent by value, with Laredo holding a major share of it.

Truck Crossing Channels

Road is the main channel at Laredo. By crossing counts, about one in four cross-border commercial trucks passes through Laredo, which is the direct reason for the density of local logistics services: carriers are willing to commit capacity here, and broker and warehouse inventory concentrates with it.

The practical meaning of the FAST lane is a faster crossing path for carriers and importers that have completed compliance filings. Using it requires advance registration, with carrier vehicles, drivers and the importer all on file and cargo accompanied by conforming documents. For exporters from China with a fixed monthly volume, fixing the carrier and completing the filing usually shortens crossing queue time noticeably. Automated scales let a vehicle complete weighing as it passes, so vehicles over axle load limits do not need separate handling at the bridgehead.

Air Cargo Channel

Laredo's air port of entry status is unusual on the US-Mexico border: the airport has both US customs operations and Mexican customs pre-clearance facilities, and operates 24 hours. This lets high-value or time-critical cargo complete both countries' entry procedures at the same location.

The operational value of dual customs operations is that a single shipment can complete both countries' import formalities on the Laredo side, avoiding a second clearance further inland. This channel mainly serves high value density and time-sensitive cargo, such as automotive electronics, aerospace parts and repair returns. For exporters from China, the applicable scenarios are high-value orders with short delivery windows, or replenishment that must align tightly with the production schedule of a plant on the Mexican side.

Trade Volume

Measured by trade value, Laredo stands at the top of the US-Mexico border ports and near the top of all US ports. The practical meaning of this scale for importers is route density and carrier count: volume determines how many trucking companies will run the lane and how quickly problems get resolved.

Laredo's cargo mix differs from a purely consumer-oriented port: imports are led by auto parts, computers and consumer electronics, and exports are also led by auto parts, with substantial round-trip movement within the same supply chain on both sides. That means local volume is clearly driven by auto and electronics production schedules and does not track retail stocking cycles exactly. When judging how tight local operations are, auto plant production schedules are usually a better reference than retail peak season.

Main Import and Export Commodities

Laredo's main cargo types concentrate in autos, electronics and machinery. Its category concentration is high among US ports, with a large number of categories leading US imports or exports, which is directly related to the auto and appliance manufacturing belt in northern Mexico.

Under the US customs and census accounting, Laredo leads national imports in 13 of the top 20 import categories and national exports in 10 of the top 20 export categories, with leading categories including auto parts, insulated wire and cable, tractors, air conditioners, electrical switch panels, refrigerators and freezers, vehicle engines, seats, catalytic converters, silver, electric motors and generators, and spirits such as tequila. About 96 percent of Laredo imports come from Mexico, with most cleared under USMCA preferential rates. Worth noting is that agreement preferences are not automatic: origin certification must be provided at entry and the classification and regional value content rules met, otherwise normal rates apply.

Industrial Parks and Warehousing

Laredo's warehousing and transfer capacity is a basic condition of the port. Local warehousing investment over the past three years has exceeded USD 1 billion, more than the previous 15 years combined, reflecting real demand for intermediate steps from cross-border volume.

The practical value of warehousing and transfer capacity for importers is as a place to deconsolidate, re-document and rework. When a shipment needs to be split between the US and Mexican sides, or labels and packaging need to be reorganized before crossing, local warehouses absorb that work and avoid longer round trips for rework. The high concentration of brokers and forwarders also means clearance, inspection, crossing and delivery for the same shipment can be handled by one or two local providers, reducing handoffs.

Customs Inspections and Release

Inspections are decided by Customs and Border Protection and relate to entry compliance, history and cargo type. Inspections in Laredo are completed at the bridge crossing points and inside the yards, with seizure and penalty matters handled by a dedicated local window.

The practices for reducing inspection probability are the same at land ports as at seaports: declared description matching the goods, prices consistent with the common range for comparable goods, avoiding undervaluation and mixed loads, maintaining continuous import records, and aligning document information with container marks and labels. Land ports add one specific requirement: consignor and consignee names and addresses on the commercial invoice, packing list and waybill must correspond exactly, and mismatched parties, a common issue in cross-border transport, is a frequent inspection trigger.

Foreign-Trade Zone

Laredo's duty arrangements sit in Foreign-Trade Zone 94. The grantee is the City of Laredo, and the coverage includes the airport and the industrial belt. For companies that need to store, sort or reprocess imported components before deciding on domestic sale or re-export, this arrangement can defer or avoid duty payment.

Unlike the Alternative Site Framework used at inland points, Laredo's foreign-trade zone is mainly designated sites, with usable space on the airport side and along the industrial belt. The main benefits inside the zone are duty deferral and duty-free re-export; when the component rate is higher than the finished-goods rate, domestic sale can also be cleared at the finished-goods rate, which is inverted tariff treatment. Applicability requires prior approval.

Routing Options from China

Chinese cargo moves through Laredo in four ways, differing in the port of entry, whether there is processing on the Mexican side, and whether truck or rail completes the domestic leg.

The first and second types differ mainly in domestic distance and ocean freight. The third enters at a node inside Mexico, requiring Mexican-side clearance and transport arrangements, and suits flows whose destination is mainly the Mexican market. The fourth accounts for a high share of Laredo volume, consistent with the structure where auto parts lead both imports and exports. The key variable in choosing among them is the final delivery point, not the prominence of the port of entry.

Transit Times from China

Transit times are estimated by seaport leg and domestic leg separately, with the seaport leg using the same common ranges as the other US port pages.

These figures exclude booking, loading, export clearance and destination clearance time. The Mexican Pacific port option has a shorter ocean leg but requires a Mexican import entry before northbound movement, and once the two ends' formalities and land transport are stacked the total time is close to the West Coast southbound route. Suez routings are affected by conditions in the Red Sea and Cape of Good Hope diversions occur from time to time, so actual ocean time may rise by more than a week.

Operating Hours and Holidays

One key difference from seaports is that crossing hours are affected by holidays on both sides at once. When the US side closes, trucks cannot cross, and when Mexican customs are on holiday, northbound trucks cannot complete the handoff either, so scheduling needs both countries' calendars.

In practice, the periods to avoid are around US Thanksgiving, Christmas and New Year, and the Mexican national holiday and year-end break. The full US holiday list is in the US holidays overview. If a delivery plan contains fixed deadlines, two to three working days of buffer on either side of major holidays is advisable.

Off-Peak and Peak Seasons

Laredo's volume rhythm is set by auto and electronics production schedules, the Mexican agricultural export season, and retail stocking cycles. Its swings do not track purely consumer-oriented ports exactly, and auto plant production plans should be the main reference.

Three local variables to anticipate: the June to November Gulf hurricane season affecting Houston-direction ports and domestic road legs; overlapping US year-end and Mexican holidays causing crossing interruptions; and the short volume dip from annual auto industry maintenance shutdowns. Peak-season bookings are best placed two to three weeks ahead, with one to two weeks of buffer in the delivery plan.

Pickup and Transfer Process After Arrival

Pickup at Laredo means pulling a container or trailer from a yard or customs-controlled area. The steps are similar to a seaport terminal, with the difference that crossing requires complete formalities on both sides.

1. Cargo discharges at a West Coast or Gulf seaport and moves by rail or truck to Laredo, or northbound from the Mexican side to Nuevo Laredo.
2. Complete the US import entry before crossing and obtain release, or remain under bond; cargo with a Mexican direction also completes the Mexican formalities.
3. Settle ocean freight, rail intermodal charges, yard charges and related surcharges and obtain a pickup or trailer instruction.
4. Book the crossing or pickup slot against the bridge or yard's published hours and confirm chassis and tractor sources.
5. At the gate or bridge, present documents and booking information and complete inspection, weighing and release.
6. Deliver to the destination; cargo needing devanning goes to a local or nearby warehouse, or into the foreign-trade zone.
7. Return empty containers to the location designated by the carrier or container owner, with cross-border chassis and tractors returning as arranged by the carrier.

Four common causes of delay: crossing documents inconsistent with the actual load, leading to rework after inspection; charges unsettled or a lien flag leaving cargo unpickable in the system; cross-border tractor and chassis arrangements not in place; and dispatch falling outside bridge operating hours. All four can be checked through yard and broker systems before dispatch.

Port Advantages

Taken together, the value of Laredo as a US-Mexico land destination concentrates in four areas.

• Cross-border channels with backup: three bridges carry commercial freight (World Trade Bridge, Colombia Solidarity Bridge and the Laredo International Railway Bridge), with separate crossing points, and road and rail are independent, so a single congested or closed channel has an alternative path. Ports with one commercial bridge do not have this condition.
• Rail crossing capacity expanded noticeably in 2025: the Ottentsmeyer International Railway Bridge second span opened in February 2025, with about USD 100 million invested, adding 1,170 feet of bridge and about 4,500 feet of track, allowing simultaneous two-way crossings and more than doubling theoretical rail channel capacity, plus inspection and monitoring equipment.
• High service provider density: more than 500 freight forwarders, more than 100 customs brokers and about 200 trucking companies locally, and the direct result of carriers committing capacity is that vehicles are easier to find in peak season and there are more channels for resolving exceptions. Warehousing investment over the past three years has exceeded USD 1 billion, more than the previous 15 years combined.
• Port management close at hand: the Laredo Field Office is in the city, so origin determinations, rate applicability disputes, seizures and appeals can be dealt with locally without cross-state travel.

Three points need attention. First, the city is not on the coast, so the international ocean leg must be completed at another port and the domestic leg has a real effect on delivery deadlines. Second, the cargo mix is closely tied to the auto and electronics industries, and changes in industry production schedules transmit directly into crossing traffic. Third, crossing hours are affected by both US and Mexican holidays at once, so scheduling needs both calendars checked.

Frequently Asked Questions

Is Laredo a seaport?

No. Laredo is a land port of entry in southern Texas on the north bank of the Rio Grande, across from Nuevo Laredo, Mexico. There are no ocean berths; what crosses is truck trailers and railcars, and the international ocean leg is completed at Los Angeles, Long Beach, Houston or another seaport.

How many customs port codes does Laredo have?

One, code 2304, registered as Laredo, Texas. The office address is Lincoln/Juarez Bridge, Administrative Bldg. #2, Laredo, TX 78040, telephone +1 956-523-7300, with Alberto A. Flores as Port Director. Port Laredo, used by the city and its economic development bodies, is the public-facing brand name for this port of entry.

Which bridges can carry trucks?

Two road bridges plus one rail bridge. The World Trade Bridge is for commercial trucks only; the Colombia Solidarity Bridge carries commercial trucks and passenger vehicles; the Laredo International Railway Bridge carries cross-border trains. The Juarez-Lincoln Bridge and the Gateway to the Americas Bridge carry only passenger vehicles and pedestrians.

How do you choose between the World Trade Bridge and the Colombia Solidarity Bridge?

Use the World Trade Bridge as the main channel, with truck hours of weekdays 07:00-24:00 and weekends 08:00-16:00 Central Time. When it is congested or closed for maintenance, divert to the Colombia Solidarity Bridge, whose commercial channel runs weekdays 08:00-24:00 and weekends 08:00-16:00. Both bridges have FAST dedicated lanes.

What was Laredo's trade value in 2025?

USD 353.94 billion, up 4.4 percent year on year and a fifth consecutive record year, with exports of USD 126.83 billion and imports of USD 227.11 billion. It stands at the top of the US-Mexico border ports and near the top of all US ports by trade value, measured across the 450-plus airports, seaports and land ports in the national statistics.

How long is the truck crossing queue?

Local commercial truck crossings run close to 19,800 per day, with about 14,000 across the two commercial bridges combined. Weekday mornings and afternoons each have a peak, and registered carriers can use the FAST dedicated lane to shorten queuing. Actual waiting time can be checked on the US customs border wait time system for the day of crossing.

Has rail crossing capacity changed?

Yes. In February 2025 CPKC opened the second span of the Patrick J. Ottentsmeyer International Railway Bridge, with about USD 100 million invested, adding 1,170 feet of bridge and about 4,500 feet of track. The new span sits about 35 feet from the original and allows simultaneous two-way crossings, more than doubling theoretical rail channel capacity. Railcars entering the United States from Mexico through Laredo numbered 213,008 in 2025.

Which railroads operate on the US and Mexican sides?

On the US side, Union Pacific and Kansas City Southern (KCS, now part of CPKC) provide service, with KCSM handling the handoff between Laredo and Nuevo Laredo. The Laredo International Railway Bridge is owned by KCS, is single-track, and is shared by UP and KCS. UP operates two yards in Laredo and provides intermodal service within 8 miles of most industrial parks.

How long does sea freight from China to Laredo take?

The common range via Los Angeles or Long Beach is about 18 to 28 days, with an ocean leg of about 14 to 22 days; via Houston about 32 to 43 days; via Manzanillo or Lazaro Cardenas in Mexico about 24 to 35 days. Air freight via Laredo International Airport runs about 3 to 7 days door to door.

What are the local customs office hours?

Port office hours are Monday to Friday 08:00-17:00 Central Time, closed Saturday and Sunday. Individual channels have their own hours: the World Trade Bridge commercial channel runs weekdays 07:00-24:00 and weekends 08:00-16:00; the Colombia Solidarity Bridge commercial channel runs weekdays 08:00-24:00 and weekends 08:00-16:00; rail and airport channels operate 24 hours.

What happens if cargo is inspected?

Inspection is completed at the bridge crossing point or inside a yard, with no cross-city drayage. Penalty and seizure matters are handled by the local window at (956) 523-7367, weekdays 08:00-17:00. Service, lifting and handling, devanning labor and storage charges during the inspection are borne by the consignee regardless of outcome. Food and agricultural cargo is handled by the US Food and Drug Administration resident office at the World Trade Bridge.

Can cargo be returned to China?

Yes, provided it has not been consumed or delivered in the United States and remains under customs control. Return requires an export entry in the United States and an import declaration in China, and duty-free treatment can be applied for within the prescribed period for returns in the original condition on quality or specification grounds. Cargo entering through Laredo must move to an export seaport before loading, and that cost should be calculated in advance.

Is there a local foreign-trade zone?

Yes. Foreign-Trade Zone 94 was granted by the City of Laredo, with usable space on the airport side and along the industrial belt. The main benefits inside the zone are duty deferral and duty-free re-export, plus inverted tariff treatment allowing domestic sale at the finished-goods rate when that rate is lower than the component rate. Related guidance is in the US customs information section.
