Long Beach Port: Silent Engine of US Imports

April 8, 2026 · 9 min read · Port Operations

The Port of Long Beach is the second-busiest container port in the United States and a critical component of the San Pedro Bay port complex, handling approximately 9.1 million twenty-foot equivalent units (TEUs) in 2024. Situated adjacent to the Port of Los Angeles on the southern California coast, it occupies 3,200 acres of land and water, operates 10 piers with 80 berths, and facilitates over $200 billion in annual trade. Together with its neighbor, the Port of Long Beach processes roughly 40% of all containerized imports entering the United States, making it one of the most consequential pieces of trade infrastructure in the Western Hemisphere.

History and Development

The Port of Long Beach was founded in 1911, four years after the Port of Los Angeles began formal operations. The city of Long Beach developed its harbor facilities along the eastern side of San Pedro Bay, initially focused on oil exports — the discovery of the Wilmington Oil Field in 1932 made the port one of the largest petroleum export points on the Pacific Coast.

The transition from oil and break-bulk cargo to containerized shipping began in the 1960s. Long Beach was an early adopter of container technology, and by the 1970s had established itself as a major container gateway. The port's willingness to invest in purpose-built container terminals and deep-water berths attracted major shipping lines, particularly those operating trans-Pacific services.

A defining moment came in 1980 when China's COSCO Shipping (then China Ocean Shipping Company) selected Long Beach as its first US port of call. This relationship deepened over decades, and the COSCO-operated Pier J terminal became one of the busiest at the port. The partnership symbolized the broader trend of Long Beach becoming a primary gateway for Chinese manufactured goods entering the American market.

The 21st century brought massive infrastructure investment. The $4.6 billion Middle Harbor Redevelopment Project, which consolidated two aging terminals into a single state-of-the-art facility, began construction in 2011 and reached substantial completion by 2021. The project created the Long Beach Container Terminal (LBCT), the most technologically advanced container terminal in North America.

Infrastructure and Capacity

The Port of Long Beach's infrastructure reflects decades of continuous investment and modernization. The port's terminals are operated by a mix of carrier-affiliated and independent terminal operators.

Key infrastructure specifications include:

Total acreage: 3,200 acres of land and water
Piers: 10 piers with 80 berths total
Container terminals: 6 major container facilities
Container cranes: Over 70 ship-to-shore gantry cranes, including the tallest cranes in the Western Hemisphere at LBCT (305 feet above the wharf deck)
Channel depth: 76 feet in the main channel (the deepest on the US West Coast), with berth depths of 50 to 55 feet
On-dock rail: Available at 5 container terminals, connecting to the Alameda Corridor
Annual TEU capacity: Approximately 14 million TEUs at full theoretical throughput

The Long Beach Container Terminal at Middle Harbor deserves particular attention. Operated by a consortium led by Mediterranean Shipping Company (MSC), it employs automated stacking cranes, automated guided vehicles, and advanced terminal operating systems. The 300-acre facility can handle up to 3.3 million TEUs annually, making it the single highest-capacity terminal in the United States. Its zero-emission electric equipment and shore-power infrastructure make it the greenest container terminal in the country.

The port's 76-foot main channel depth is a significant competitive advantage. It is the deepest commercial shipping channel on the US West Coast, capable of accommodating fully laden Ultra Large Container Vessels (ULCVs) of 20,000+ TEU capacity without tidal restrictions. This depth advantage attracts the largest vessels on trans-Pacific routes, which seek to maximize container loads per voyage.

Trade Routes and Key Commodities

The Port of Long Beach is overwhelmingly oriented toward trans-Pacific trade. East Asia accounts for approximately 70% of all container movements, with China as the single largest trading partner. Japan, South Korea, Vietnam, and Taiwan round out the top five. The port also handles trade with Southeast Asian nations and, to a lesser extent, with Australia, New Zealand, and Latin America.

Top import commodities include:

Crude oil and petroleum products — Long Beach remains a significant energy import point
Electronics and electrical equipment — consumer electronics, computing equipment, and components
Plastics and rubber products — raw materials and finished goods
Furniture and fixtures — residential and commercial furnishings
Automotive parts and vehicles — for assembly and direct retail distribution

Major export commodities include:

Petroleum coke — a byproduct of oil refining, exported in large volumes to Asia
Waste paper and scrap materials — recycled feedstock for Asian manufacturing
Animal feed — including distillers dried grains and hay
Chemicals — industrial chemicals and specialty compounds
Cotton — sourced from California's Central Valley

Like its neighbor, Long Beach contends with a structural trade imbalance. Import containers outnumber export containers by roughly two to one, generating a steady flow of empty containers that must be repositioned.

The San Pedro Bay Complex

Understanding Long Beach requires understanding its relationship with the Port of Los Angeles. The two ports share San Pedro Bay, share the Alameda Corridor rail connection, and compete for many of the same shipping lines and cargo. Yet they operate as entirely independent entities, governed by separate harbor commissions appointed by their respective city governments.

This dual-port structure creates both competition and cooperation. The ports compete aggressively for terminal leases and shipping line calls. At the same time, they collaborate on shared infrastructure (the Alameda Corridor), environmental programs (the Clean Air Action Plan), and navigational safety (the shared vessel traffic service). The competitive dynamic has generally served the supply chain well, driving investment and innovation at both ports.

The combined San Pedro Bay complex handled approximately 19 million TEUs in 2024, making it the ninth-largest port complex in the world — larger than any European port and comparable to major Asian hubs outside of China. This concentration of capacity in a single bay creates enormous economic value and equally significant operational risk.

Economic Impact

The Port of Long Beach generates substantial economic impact at local, regional, and national scales. According to port-commissioned studies, the facility supports approximately 575,000 jobs across Southern California, including direct employment (dockworkers, terminal operators, truck drivers), indirect employment (warehousing, logistics, customs brokerage), and induced employment (services supporting port workers and their families).

The port generates an estimated $100 billion in trade-related economic activity annually and contributes over $5 billion in federal, state, and local tax revenue. It is the single largest revenue generator for the City of Long Beach, funding municipal services through harbor department revenues.

The Inland Empire — the sprawling region of Riverside and San Bernardino counties east of Los Angeles — has become the primary warehouse and distribution zone for cargo arriving through the San Pedro Bay ports. Over 1.5 billion square feet of industrial warehouse space has been developed in the region, making it the largest concentration of logistics real estate in North America.

Environmental Leadership

The Port of Long Beach has positioned itself as an environmental leader among global ports. Its environmental programs are among the most ambitious in the industry.

Key initiatives include:

Green Port Policy: Adopted in 2005, establishing the framework for environmental management across all port operations
Clean Air Action Plan: Joint program with the Port of Los Angeles targeting an 80% reduction in port-related emissions
Shore power requirements: Mandatory use of shore-side electrical power by container ships, cruise ships, and refrigerated cargo vessels while at berth
Green Ship Incentive Program: Provides financial incentives to vessel operators deploying cleaner ships
Zero-emission goals: Commitment to transition all cargo handling equipment to zero-emission technology by 2030 and all drayage trucks by 2035

The LBCT at Middle Harbor demonstrates what is achievable. Its all-electric automated equipment — powered by renewable energy through the city's utility — produces zero direct emissions during cargo handling operations. This is the template the port envisions scaling across all terminals.

What Makes the Port of Long Beach Different From Los Angeles?

Despite their proximity, the two ports have distinct characteristics. Long Beach has deeper channel draft (76 feet versus 53 feet), making it better suited for the largest ULCVs. Long Beach also has a more advanced automated terminal in LBCT. However, the Port of Los Angeles has greater total acreage and more container terminals. Shipping lines often maintain operations at both ports, using them as complementary facilities.

How Did the Supply Chain Crisis Affect Long Beach?

The 2021-2022 supply chain crisis hit Long Beach with full force. At the peak, over 100 container ships were anchored or drifting off the coast waiting for berth space — the majority destined for Long Beach or Los Angeles. The crisis exposed the fragility of just-in-time supply chains dependent on a single port complex. In response, the port accelerated investment in digitization, including the deployment of the Port Optimizer data platform to improve cargo visibility and reduce dwell times. The crisis also strengthened the case for automation and 24/7 operations.

Current Challenges and Future Outlook

The Port of Long Beach faces several key challenges. Trade policy uncertainty, including tariffs and potential shifts in US-China relations, directly affects the port's core trans-Pacific volumes. The diversification of Asian manufacturing to Vietnam, India, and other markets creates new trade lanes but also new routing options that may bypass West Coast ports.

Infrastructure aging is an ongoing concern. While LBCT represents the state of the art, several other terminals at the port operate on older infrastructure that requires significant capital investment. The port has outlined a multi-billion-dollar capital program for the next decade, but funding constraints and permitting challenges can slow implementation.

Labor dynamics continue to evolve. The 2023 ILWU contract addressed many immediate concerns, but the fundamental tension between automation and employment remains unresolved. The port must balance the operational benefits of automation against community and labor impacts.

Conclusion

The Port of Long Beach operates with less public visibility than its Los Angeles neighbor but carries an equally critical share of American trade. Its combination of the deepest channel on the West Coast, the most advanced automated terminal in North America, and strong environmental commitments positions it well for the future. However, the structural challenges of trade concentration, infrastructure maintenance, and the transition to zero-emission operations will demand sustained investment and strategic planning. For anyone in maritime logistics, the Port of Long Beach is not a secondary facility — it is half of the most important port complex in the Americas.
