Port of Mobile terminal guide: 50-foot Gulf container channel operations

Mobile Location

Mobile lies at roughly 30 degrees 41 minutes north and 88 degrees 02 minutes west, on the north shore of the Gulf of Mexico, where the Mobile River runs south through the city into the bay. The location's defining feature is that water and land conditions hold at once: about three hours of steaming south reaches open Gulf water without passing a long bay, while inland the waterway system connects the central US hinterland.

• State: Alabama, in the southeastern United States, bordering Tennessee to the north, Georgia to the east and Mississippi to the west, with the Gulf of Mexico to the south
• Port area: Both banks of the Mobile River and the north shore of Mobile Bay, divided into the upper port, main terminal area, lower port and Middle Bay Port, about 3,700 acres of land combined
• Distance to open sea: About three hours of steaming from the port area to open Gulf water; vessels reach the sea directly without a narrow inner bay
• Main highways: I-10 east-west (east to Jacksonville, west toward New Orleans and Houston); I-65 north-south (north to Birmingham, Nashville and Chicago directions)
• Rail: Five Class I railroads and four short lines converge in the same yard, with the port's own switching railroad handling in-port placement
• Inland waterway: Direct access to the Tennessee-Tombigbee Waterway and Gulf Intracoastal Waterway, reaching nearly 15,000 miles of inland waterway
• Airports: Mobile Aeroplex at Brookley and Mobile Regional Airport, both operated by the Mobile Airport Authority
• Metro area: More than 400,000 people; industry centers on port logistics, shipbuilding and repair, aerospace manufacturing (Airbus final assembly), chemicals and paper

Seaport of Entry Overview

Mobile's identity in the customs system is a seaport of entry, code 1901, registered as Mobile (Including Theodore), Alabama, with jurisdiction including the Theodore industrial canal to the west. The field office is in New Orleans rather than locally.

The field office being out of port means some matters run through New Orleans, such as origin determination disputes, seizure appeals and some trade enforcement cases. Routine import entry, release and inspection are all completed at the Mobile port, so day-to-day operations are unaffected. General rules on commodity admission and duty rates are covered in the US customs policy and additional tariff section.

Container Terminal

Mobile's container operations concentrate at a single terminal, APM Terminals Mobile, operated since 2008. The single-terminal structure keeps container flows in one area: port entry, clearance, pickup and rail transfer all complete in the same zone, with no drayage between terminals.

The single-terminal structure has two direct effects for importers: the same shipment does not land at different terminals on different sailings, so the pickup location is stable, and there is only one set of working windows and appointment rules, simplifying dispatch. Note that APM Terminals Mobile handles both imports and exports with a fairly balanced flow: exports are led by frozen poultry, grain and forest products, imports by metal products, wood products, oversized cargo, consumer goods and chemicals.

Berths and Draft

Mobile's deepwater condition is the direct result of the 2025 channel project. The work deepened the ship channel from 45 to 50 feet and widened it, so fully loaded large container ships can berth without lightening, a condition at the leading edge among Gulf Coast container terminals.

Draft matters for vessel type and box count: container liner capacity and draft are directly linked, and every foot of channel depth lets a ship carry another tier. Mobile previously took only 9,000 to 10,000 TEU ships, with some sailings needing lightening before arrival or transfer outside the bay; after deepening, 12,000 to 16,000 TEU ships can enter fully loaded. For importers this changes the space structure and freight rate basis, not just berthing efficiency.

Channel Modernization Project

The modernization project is the key to understanding Mobile's changes over the past decade. Authorized by Congress in 2018, dredging began in 2020 and completed in October 2025, seven years in all.

The direct result is that large vessels can berth fully loaded without lightening outside the bay or diverting to other ports. A secondary effect is the port's changing role in the liner network: once vessels can enter fully loaded, carriers are more inclined to list Mobile as a direct port of call rather than a feeder transshipment point. For importers this usually shows up as more direct sailings and fewer transfer legs.

Container Throughput

Mobile is a container terminal with marked growth in recent years. In the port's own figures, container throughput has passed 500,000 TEU with a ten-year compound growth rate of 8.5 percent.

The 2025 decline relates to tariff policy changes and the labor negotiation cycle at East and Gulf Coast ports. Importers slowed ordering early in the year on tariff expectations, then concentrated on rush shipments in summer, so the throughput rhythm ran low then high. Note that the port's import and export structure is fairly balanced, with stable export commodities in coal, grain and frozen poultry, so volume swings are generally smaller than at import-dominated ports.

Liner Services and Trade Routes

Mobile's service network is led by Asia and Europe directions, extending to Midwest markets by rail. The port's positioning in the liner network is a Gulf Coast direct port of call rather than a feeder port.

For shippers from China, Mobile suits three business types: consignees in Alabama, western Georgia, Tennessee or Mississippi; cargo needing rail distribution to inland hubs such as Memphis and Chicago; and bulky, mid-unit-value goods such as furniture, appliances and auto parts. If the consignee is on the West Coast or in the Northeast, entering via a West or East Coast port is usually more direct, and routing around the Gulf is not economical.

Ocean Services and Transit Times from China

The basic routing from China to Mobile is all-water direct to the Gulf via the Panama Canal; the alternative is a mini-bridge via a West Coast port. The first has lower freight cost, the second shorter transit.

These ranges are the overlap of multiple forwarders' published transit tables and exclude cut-off, clearance and inland delivery time, and do not constitute a commitment. Three variables affect actual timing: Panama Canal dry-season draft restrictions, more common in El Nino dry seasons, usually adding three to seven days; the June to November hurricane season, when Gulf Coast port areas may close temporarily; and the shipment surge around Lunar New Year, which tightens space and queues port handling. Where the delivery plan falls in these windows, allow an extra one to two weeks beyond the sailing schedule.

Terminal Gates and Pickup

Mobile's pickup flow matches most US container ports, with the difference that operations concentrate at a single terminal and truck turns are fast. The port publishes round-trip times under 45 minutes, clearly shorter than the two to three hour US average.

1. The vessel discharges at a container terminal berth and containers enter the 149-acre yard per the stacking plan.
2. The broker completes the import filing and obtains release, or arranges bonded onward movement.
3. Ocean freight, terminal handling, storage and related surcharges are settled and the pickup instruction is issued.
4. A gate slot is booked in advance per terminal rules and chassis availability is confirmed.
5. The vehicle enters the terminal through the port area entrance, presents documents and collects the container.
6. Cargo moving to inland rail is handed over at the in-port ICTF and can be loaded and dispatched within one business day.
7. Empties are returned to the location designated by the carrier, with reefers handled per cold chain requirements.

Three delay causes are common: appointment times that do not match the terminal's working window, requiring rebooking when late; incomplete driver credentials or vehicle registration blocking gate entry; and no chassis available. The last needs attention on the Gulf Coast, since Mobile's total local truck and chassis capacity is smaller than Houston and Miami, with less scheduling slack in peak season, so the collection step should be confirmed separately before dispatch.

Rail Access

Rail is Mobile's most distinctive condition. Nine railroads converge in the same yard, five of them Class I, and containers can complete the ship-to-rail transfer at the in-terminal ICTF.

Nine railroads in one yard means line choice. For the Chicago direction, for example, importers can compare schedules and rates across different Class I railroads rather than accepting a single carrier's quote. The port-owned TASD handles in-port placement, linking the terminal, warehouses and industrial sites to each railroad's mainline yard, which is what makes in-port rail work reliably. The practical advice for importers: if the consignee is in the Midwest, price the rail leg at booking, which is usually more economical than finding eastbound trucking after arrival.

Inland Waterway and Barge Access

Mobile has both deepsea and inland barge conditions. The port area connects directly to the inland waterway system, so breakbulk, liquid bulk and oversized cargo can complete the ocean-to-barge transfer inside the same port area.

For container-focused importers the barge conditions are usually not used, but they enter consideration in two cases: oversized and overweight equipment, where ship-to-barge direct loading avoids a second lift at the terminal; and bulk raw material or agricultural imports and exports, where barges push the long-haul cost below road. Breakbulk handling and storage arrangements differ from containers, and yard and lifting capacity should be confirmed with the terminal operator in advance.

Road Access

Road conditions form a cross of two interstate highways. I-10 carries long-haul east-west and I-65 north-south, crossing inside Mobile, with the port area a short distance from both trunk routes.

• I-10: East-west, east to Jacksonville and west toward New Orleans and Houston
• I-65: North-south, north to Birmingham, Nashville, Indianapolis and Chicago
• Local congestion: Roads around the port area carry less load than major East and West Coast ports, and entry times are relatively stable
• Under construction: New I-10 Mobile River Bridge, investment about USD 2.7 billion, planned to start construction in 2027
• Truck turnaround: Terminal round trips average under 45 minutes; in and out under one hour on average
• Drayage radius: Local warehouses and yards mostly within half an hour; Birmingham about two and a half hours, Nashville about five hours, Atlanta about five and a half hours

The Mobile River Bridge under construction is a variable to watch over the next few years. Once work starts, some road sections around the port area will enter construction and traffic lines may adjust in phases. The advice for dispatch planning is to allow extra transit time during the project period and confirm the current detour plan with the fleet.

Air Cargo Channel

Mobile's air cargo is handled by two airports, both operated by the Mobile Airport Authority, the same body as the FTZ operator for the port authority's facilities. Both airports' runway conditions can take freighter types.

Sea and air are handled under the same port code, unlike ports where sea and air belong to separate ports. For importers the practical effect is that the sea and air legs of the same shipment can be filed under one port's rules, with a more unified documentation basis. Mobile's air scale is modest, serving mainly high-priority and high-value cargo plus aerospace manufacturing parts; bulk routine cargo still moves by sea.

Breakbulk and Ro-Ro Operations

Containers are only part of Mobile's business. The port area also handles steel, coal, forest products, finished vehicles and project cargo, with these working areas scheduled separately from the container terminal.

• Upper port, Blakeley Island Terminal: breakbulk and general cargo operations
• Main terminal area: Alabama Steel Terminals for steel; AutoMobile International ro-ro terminal for finished vehicle imports and exports
• Lower port: cold store, container terminal, ICTF, logistics park, McDuffie coal terminal and Pinto steel terminal
• Middle Bay Port: liquid bulk terminal
• Theodore industrial canal: 40 feet deep, serving oil and gas, chemical and agricultural project cargo
• Main breakbulk types: coal, steel, forest products, grain, finished vehicles, project and oversized cargo

A multi-commodity port area has two effects for importers. First, port-area roads carry container trucks, bulk trucks and project cargo transport at the same time, so dispatch should enter via the terminal's published entrance and avoid straying into other working areas. Second, ro-ro and container berths sit on different shorelines, so vehicle cargo scheduling needs separate confirmation and cannot follow the container sailing schedule. Exports of coal, grain and frozen poultry are Mobile's stable commodities and the reason its import and export structure is fairly balanced.

Customs Inspections and Release

Inspection selection is decided by CBP and relates to declaration compliance, history and commodity. Mobile's windows are split by business type, with cargo matters separated from agriculture, immigration and seizure desks.

Wood products and wood packaging are one category needing advance handling in Mobile imports. Cargo with solid wood packaging must complete heat treatment or fumigation per international plant quarantine standards and bear the mark; untreated or non-compliant packaging is a common cause of inspection and return shipment. Pressure vessels, chemicals and aerospace parts carry additional admission requirements, and any needed registration or certification should be confirmed before shipping.

Foreign-Trade Zone 82

Mobile's tariff arrangement sits in Foreign-Trade Zone 82. The grantee is the City of Mobile and the operator is the Mobile Airport Authority, a different body from the port authority's deepwater facilities but working in coordination.

Mobile's FTZ is closely tied to local manufacturing. Petrochemical, shipbuilding, paper and aerospace companies around the port area store imported raw materials or components in the zone for processing before domestic sale or re-export, deferring or reducing the duty burden. The main benefits are duty deferral and re-export exemption; where the imported component rate exceeds the finished product rate, domestic sale can be processed at the finished product rate, which is the inverted tariff benefit, with use requiring prior authorization. Related information is covered in the US customs information section.

Working Hours and Holidays

Mobile's port office and terminal hours should be read separately. The port office works 08:00 to 16:00 on weekdays, while terminal gates and yards work their own published hours, and the two do not fully overlap.

The times to avoid most are federal holidays and the year-end period. There are 11 US federal legal holidays in total; the full list is in the US holiday section. Hurricane season is a Gulf Coast-specific variable: the port area closes on plan during hurricane warnings, stopping gate work and vessel operations, with storage arrangements during closure following port authority announcements. If the delivery plan falls between June and November, allow three to five days of slack in the sailing schedule.

Peak and Off-Peak Seasons

Mobile's volume rhythm is set by three overlapping lines: Asia retail and e-commerce stocking, automotive and manufacturing parts replenishment, and the seasons for export bulk commodities such as coal, grain and frozen poultry. Its swings are smaller than at consumption-import-dominated ports.

Three local variables should be planned for: Panama Canal dry-season draft restrictions adding delay; the June to November hurricane season possibly closing the port area temporarily; and increased large-vessel calls after the new channel, raising berth and yard scheduling density in peak season. Booking in peak season is best placed two to three weeks ahead, with one to two weeks of buffer in the delivery schedule. Overall transport arrangements are covered in the China-US freight section.

Port Advantages

Taken together, Mobile's value as a Gulf port of entry rests on four points.

• Deepest container channel on the Gulf: the ship channel reached 50 feet in October 2025, with the project also creating two-way transit and nearly 3 miles of new passing channel. Fully loaded large container ships can berth without lightening, putting the port into the direct-call sequence for 12,000 to 16,000 TEU vessels and changing the space and freight rate basis.
• Nine railroads in the same yard: five Class I railroads and four short lines converge at Mobile, the port-owned switching railroad handles in-port placement, and the in-terminal ICTF allows direct loading at the berth, with about 3 days from Mobile to Chicago. Midwest consignees can arrange the rail leg at booking.
• Process certainty from a single container terminal: container operations concentrate at APM Terminals Mobile, so the pickup location is stable and there is only one set of gate and appointment rules; the port publishes truck round trips averaging under 45 minutes, clearly shorter than the two to three hour US average.
• Containers, breakbulk, ro-ro and barges in one port area: the port also handles steel, coal, forest products, finished vehicles, project cargo and liquid bulk, with direct access to nearly 15,000 miles of inland waterway. An importer with mixed container and oversized business can plan it in one port area.

Three points need attention. First, local truck and chassis capacity is smaller than Houston and Miami, with less scheduling slack in peak season, so the collection step should be confirmed separately before dispatch. Second, the port's field office is in New Orleans, so origin disputes and seizure appeals run through New Orleans. Third, export bulk commodities account for a high share, so the import-export box balance shifts with season, and empty return arrangements on some sailings should be confirmed with the carrier in advance.

Frequently Asked Questions

Where is the Port of Mobile?

The port sits in southwestern Alabama between the Mobile River and Mobile Bay on the north shore of the Gulf of Mexico. It is divided into the upper port, main terminal area, lower port and Middle Bay Port, about 3,700 acres of land combined, about three hours of steaming from open Gulf water.

What is the CBP port code for Mobile?

Seaport code 1901, registered name Mobile (Including Theodore), Alabama, registered address 150 N. Royal Street, Suite 3004, Mobile, AL 36602, telephone +1 251-378-7600, port director Anthony Acrey, open Monday to Friday 08:00 to 16:00 Central Time. The field office is in New Orleans.

How many container terminals does Mobile have?

One. Container operations concentrate at APM Terminals Mobile (operating since 2008), covering 149 acres with 4 Super Post-Panamax and 2 Post-Panamax cranes, a 2,400-foot deepwater berth at 50 feet draft, 325 reefer plugs, and an in-port ICTF for direct ship-to-rail transfer.

What is the channel draft?

The ship channel is 50 feet (15.2 meters), reached on October 3, 2025, up from 45 feet. The project also created two-way transit and nearly 3 miles of new passing channel. The Theodore industrial canal has 40 feet of draft. The turning basin near the container terminal is still under construction, with dredged material used for Dauphin Island shoreline restoration.

How long does ocean freight from China to Mobile take?

All-water via the Panama Canal: Shanghai and Ningbo about 25 to 33 days, Yantian about 26 to 34 days, Xiamen about 27 to 35 days, Qingdao about 28 to 36 days; transshipment routings add five to ten days on that basis. Via a West Coast port on the mini-bridge, about 22 to 30 days end to end. These ranges are the overlap of multiple forwarders' published tables and exclude cut-off, clearance and inland delivery time.

What is Mobile's throughput?

In the port's own figures, annual container throughput has passed 500,000 TEU. The terminal operator reported 2024 as a record year at 629,837 TEU, with 2025 falling to 521,431 TEU. The ten-year compound growth rate is 8.5 percent, up 127 percent on the 2015 baseline and 24 percent above pre-pandemic 2019.

Which railroads serve the Port of Mobile?

Nine railroads converge in the same yard, five of them Class I: BNSF, Canadian Pacific Kansas City, Canadian National, CSX and Norfolk Southern; and four short lines: Alabama and Gulf Coast Railway, CG Railway, Alabama Export, and the port-owned Terminal Railway Alabama State Docks. The port switching railroad has 100 cars, 8 locomotives and 75 miles of track, with about 3 days from Mobile to Chicago.

What should be watched for at pickup?

Three points. First, an appointment system applies, recommended one to two working days ahead and earlier in peak season. Second, a valid federal TWIC card is required to enter the port area, with vehicle and driver information registered per terminal requirements. Third, local truck and chassis capacity is smaller than Houston and Miami, so confirm availability at the collection point before dispatch. Exact gate and yard hours follow the terminal's same-day publication.

What are the customs office hours?

Monday to Friday 08:00 to 16:00 Central Time, closed at weekends. Branch windows: the import specialist and entry windows via (251) 378-7600 ext. 5 and ext. 4; inspection and agriculture services ext. 2; immigration services ext. 3; seizures and detentions ext. 6, Mobile.fpf@cbp.dhs.gov.

What happens if cargo is inspected?

Inspections are completed in the terminal yard or a designated warehouse; progress can be checked at (251) 378-7600 ext. 2, fax (251) 378-7680. Service fees, lifting and handling, devanning labor and storage during the inspection are borne by the consignee regardless of the outcome; reefer cargo incurs additional plug-in and temperature control charges.

Can cargo be returned to China?

Yes, provided the goods have not been consumed or delivered in the United States and remain under customs control. A return requires export clearance in the United States and an import filing in China, and duty-free return of goods in their original condition may be claimed within the prescribed period where the cause is a quality or specification issue. Cargo entering via Mobile can reload locally, but confirm first whether the carrier accepts return in the original container.

Is there a foreign-trade zone?

Yes. FTZ 82 is tied to the Mobile seaport, with the City of Mobile as grantee and the Mobile Airport Authority as operator, registered address 2062 Old Shell Rd., Mobile, AL 36607. The zone has multiple authorized subzones involving shipbuilding, chemicals, agricultural technology and electronics companies. The main benefits are duty deferral and re-export exemption, and domestic sale can be processed at the finished product rate where the imported component rate is higher. Related information is in the US customs information section.

What are the air conditions like?

Air cargo is handled by Mobile Aeroplex at Brookley (runways 9,618 and 7,800 feet) and Mobile Regional Airport (runways 8,502 and 4,376 feet), both operated by the Mobile Airport Authority, with daily FedEx and Amazon freighter flights. Sea and air are handled under the same port 1901, with a more unified documentation basis; air from China runs about 3 to 7 days end to end.
