The Port of Los Angeles recorded the busiest month in its 118-year history in September 2026. The port handled 1,042,652 twenty-foot-equivalent units, or TEUs, during September, surpassing the previous monthly record set in July 2025 by more than 20,000 containers. Loaded imports totaled 545,696 TEUs, 19 percent more than in September 2025, while exports reached 125,751 TEUs.

The surge was not simply the result of Americans buying more goods. It also reflected a significant change in the routes companies are using to move merchandise from Asia to the United States. U.S. ocean container imports overall reached a September record, increasing 10.3 percent from a year earlier, while shipments originating in China jumped 21.2 percent.

Increasing shipments to the Port of Los Angeles illustrates the adaptability and resiliency of global supply chains despite numerous ongoing wars, trade disputes, and disruptions to traditional shipping routes. The record month for L.A. demonstrates how much the global supply chain has learned from recent disruptions.

Companies increasingly appear unwilling to depend upon a single route, supplier, or transportation strategy. Harvard professor Willy Shih described the change as moving from optimizing purely for cost toward optimizing shipping options and maintaining enough flexibility to shift production and transportation when conditions change.

Los Angeles has benefited because the trans-Pacific route provides Asian manufacturers and shippers with a relatively direct path to the enormous American consumer market. Shipping goods from China and other parts of East Asia across the Pacific to Southern California can be shorter and more fuel-efficient than sending vessels through the Panama Canal to ports on the Gulf or East coasts. Reuters reported that restrictions associated with low water levels at the Panama Canal, combined with disruptions elsewhere, have encouraged companies to shift additional freight toward Los Angeles.

Security problems surrounding the Suez Canal have reinforced that trend. Conflicts in and around the Middle East have made Red Sea shipping less predictable, while instability along other global trade routes has encouraged companies to maintain alternatives. Port Executive Director Gene Seroka specifically cited continuing challenges involving both the Suez and Panama Canal routes as contributors to Los Angeles' extraordinary cargo volumes. Lower U.S. tariffs than earlier in 2026 have also given importers greater certainty about costs, encouraging companies to replenish inventories and move holiday merchandise.

Los Angeles has absorbed the increased traffic without recreating the severe congestion associated with the COVID-era supply-chain crisis. The port also recorded its busiest quarter ever, moving nearly three million TEUs between July and September, while June through September became its strongest four-month period on record. Suppliers stocking up for the approaching holiday season in the U.S. also likely contributed to the increase in cargo volume. 

The global supply chain is not immune to war, tariffs, or transportation bottlenecks. Instead, September's record suggests that supply chains are becoming more resilient because businesses are rerouting cargo quickly when particular corridors become expensive or dangerous. Los Angeles' record month represents more than strong American imports. It demonstrates a global trading system increasingly capable of improvising around geopolitical disruption rather than simply being paralyzed by it.
