Manzanillo Port: Mexico's Largest Pacific Gateway

April 8, 2026 · 9 min read · Port Operations

The Port of Manzanillo is Mexico's largest and busiest container port, handling approximately 3.5 million twenty-foot equivalent units (TEUs) annually and accounting for roughly 46% of all containerized cargo moving through Mexico's ports. Located on the Pacific coast of the state of Colima, approximately 270 kilometers south of Guadalajara, the port is Mexico's primary gateway for trans-Pacific trade with Asia and the main entry point for containerized imports destined for the country's industrial heartland. Operated by the Administracion Portuaria Integral de Manzanillo (APIMAN), a federal port authority, the port encompasses 437 hectares of water and land, 20 berths, and serves as the western anchor of a trade corridor that connects Mexico's Pacific coast to its largest manufacturing and consumer markets.

History and Development

Manzanillo's history as a port stretches back to the Spanish colonial era. In 1522, Hernan Cortes sent expeditions from the natural bay to explore the Pacific coast, and the port served as a departure point for the Manila Galleon trade route between New Spain and the Philippines from the 16th through 18th centuries. This historical trans-Pacific connection presaged the port's modern role as Mexico's Pacific trade gateway.

For most of the 20th century, Manzanillo was a modest port handling primarily domestic cabotage, fishing, and limited international trade. The transformation began in the 1970s and accelerated with Mexico's trade liberalization in the 1980s and its accession to the General Agreement on Tariffs and Trade (GATT) in 1986. The North American Free Trade Agreement (NAFTA), which took effect in 1994, dramatically increased trade flows and drove investment in port infrastructure.

The port's growth has been remarkable. From fewer than 500,000 TEUs in the early 2000s, Manzanillo has grown to 3.5 million TEUs — a sevenfold increase in two decades. This growth has been driven by Mexico's integration into global supply chains, the expansion of its manufacturing sector (particularly automotive and electronics), and the increasing use of Mexico as both a final destination and a transit point for Asian goods entering North American markets.

The port underwent a major governance reform in the 1990s when Mexico's port system was decentralized and privatized under the Ports Law of 1993. Terminal operations were awarded to private concessionaires, while the federal government retained ownership of the port infrastructure through the API (Administracion Portuaria Integral) system.

Infrastructure and Capacity

The Port of Manzanillo operates across two main areas: the inner harbor (Laguna de San Pedrito) and the outer harbor (Bahia de Manzanillo), with specialized terminals for containers, bulk, and liquid cargo.

Key infrastructure specifications include:

Container terminals: Specialized Container Terminal I (TIMSA/SSA Marine — 40 hectares, 5 berths), Specialized Container Terminal II (Contecon Manzanillo/ICTSI — 42 hectares, 3 berths), and additional container-capable berths
Total berths: 20 across all terminals
Container cranes: Over 25 ship-to-shore gantry cranes, including neo-Panamax units with 22+ container row outreach
Channel depth: 16 meters (52 feet) in the approach channel and main basin
Berth depth: 14 to 16.5 meters (46 to 54 feet)
Rail connections: Ferromex (Grupo Mexico) and Kansas City Southern de Mexico (now CPKC) rail lines serving the port, with intermodal facilities
Annual TEU capacity: Approximately 4.5 million TEUs at current infrastructure, with expansion plans targeting 6+ million TEUs

The two primary container terminal concessionaires represent major international operators:

TIMSA (Terminal Internacional de Manzanillo): Operated by SSA Marine, one of the world's largest privately held marine terminal operators. TIMSA has invested over $500 million in infrastructure, including post-Panamax cranes, expanded container yard, and automated gate systems.

Contecon Manzanillo (CMSA): Operated by International Container Terminal Services Inc. (ICTSI), the Philippine-based global terminal operator. ICTSI won the concession for the second specialized container terminal and has invested heavily in cranes, equipment, and terminal management systems.

Expansion plans include the development of additional container berths in the outer harbor, deepening of the approach channel, and construction of new rail intermodal facilities. The Mexican federal government has identified Manzanillo as a priority port for investment under its national infrastructure program.

What Is Manzanillo's Role in the Mexico-Asia Trade Corridor?

Manzanillo is the physical gateway for the Mexico-Asia trade relationship, which has grown explosively in the 21st century. Mexico's manufactured exports to the United States — automotive, electronics, aerospace, and medical devices — depend on imported components and materials from Asia, many of which enter through Manzanillo. The port sits at the western end of a logistics corridor that connects the Pacific coast to Mexico's industrial belt: the Bajio region (Guanajuato, Queretaro, Aguascalientes, San Luis Potosi), Guadalajara's electronics cluster, and the Mexico City metropolitan area. This corridor is served by highway and rail, with a transit time of approximately 4-8 hours to Guadalajara and 12-16 hours to Mexico City.

How Does Nearshoring Affect the Port of Manzanillo?

The nearshoring trend — the relocation of manufacturing from Asia to Mexico to serve the North American market — is one of the most significant drivers of Manzanillo's growth prospects. As companies diversify supply chains away from China, Mexico's combination of competitive labor costs, trade agreement access (USMCA), proximity to the US market, and established manufacturing infrastructure makes it an attractive alternative.

However, nearshoring's impact on Manzanillo is nuanced. In the near term, nearshoring increases import volumes as new factories in Mexico require Asian-sourced components, machinery, and raw materials. Over the longer term, as domestic supply chains develop, some import volumes may decline. The net effect is expected to be strongly positive for the port, as nearshoring drives both import volumes (inputs) and export volumes (finished goods shipped to the US and other markets).

Security Challenges

The Port of Manzanillo has faced significant security challenges related to drug trafficking and organized crime. The port's role as Mexico's largest container gateway makes it a target for drug cartels seeking to import precursor chemicals (primarily from China) used in the manufacture of fentanyl and methamphetamine. In recent years, Mexican authorities and international law enforcement have seized multiple shipments of precursor chemicals at the port.

Security measures include enhanced container scanning (the port has deployed non-intrusive inspection equipment capable of scanning a significant percentage of containers), coordination with Mexican Navy and customs authorities, and participation in international programs such as the US Customs and Border Protection's Container Security Initiative (CSI). Despite these measures, security remains a persistent challenge that affects the port's operations and reputation.

Economic Impact

The Port of Manzanillo is the economic engine of the Colima coast and a nationally significant piece of trade infrastructure. The port directly and indirectly supports approximately 65,000 jobs in the Manzanillo metropolitan area and contributes significantly to federal customs revenue — port-related duties and taxes generate billions of pesos annually for the Mexican government.

The port's economic influence extends well beyond Colima. The logistics corridor connecting Manzanillo to Guadalajara and Mexico City supports trucking, rail, warehousing, and customs brokerage operations that employ tens of thousands of workers across multiple states.

Current Challenges and Future Outlook

Beyond security, the port faces infrastructure bottlenecks. The road and rail connections between Manzanillo and Guadalajara traverse mountainous terrain, with a single highway (the Manzanillo-Guadalajara highway) and one rail line handling the majority of cargo. Congestion on these corridors increases transit times and costs. Federal investment in highway expansion and rail improvements is underway but progress has been slow.

The port's inner harbor (Laguna de San Pedrito) has limited room for expansion, pushing growth toward the outer harbor and potential new development areas. Environmental permitting for port expansion in Mexico can be complex and contentious, particularly given the ecological sensitivity of the coastal zone.

Competition from other Mexican ports is increasing. Lazaro Cardenas, located to the south in Michoacan, has invested in container terminal expansion (including a facility operated by APM Terminals) and offers a deeper channel. Ensenada, in Baja California, is positioning itself as an alternative Pacific gateway with proximity to the US border.

Conclusion

The Port of Manzanillo is the indispensable link in Mexico's trans-Pacific trade and a facility of growing importance to North American supply chains. Its role as the primary entry point for Asian goods into Mexico — and increasingly, as a gateway serving nearshoring-driven manufacturing — positions it for continued growth. The challenges of security, infrastructure constraints, and competition are real, but the port's strategic advantages — geographic position, terminal capacity, and connectivity to Mexico's industrial heartland — are difficult for competitors to replicate. For trade professionals focused on Latin American and trans-Pacific commerce, Manzanillo is the port to watch.
