The Logistical Bottleneck of the Transpacific Corridor
The increase in annual capacity from 590,000 to 880,000 TEU at the Washington United Terminals (WUT) terminal in Tacoma, announced by HMM on July 31, 2026, is not simply an infrastructure upgrade: it represents a direct response to the temporal collapse of goods flow between Asia and North America. The transpacific seasonal peak has already anticipated itself in mid-May 2026, with rates for 40-foot containers rising by approximately $4,000 compared to the end of May, reaching $7,600 on the west coast and $9,000 on the east coast of the United States.
This increase in cost was fueled by an anomalous demand: companies accelerated the shipment of goods from China to anticipate possible tariff restrictions, creating an overload in the main port hubs. The WUT terminal, with its strategic location in the Pacific Northwest and its connection with The Northwest Seaport Alliance (NWSA), has become one of the most critical nodes for the flow of merchandise towards the continental interior.
The physical capacity of 590,000 TEU was no longer sufficient to handle the incoming volumes, with customs clearance times extending beyond three working days for goods destined for intermodal transport. The effect on working capital was immediate: circulating capital remained immobilized in containers blocked while waiting for unloading and customs inspection, with a direct impact on gross margins.
Automation as a Strategic Bypass of Time
HMM has chosen not a simple physical expansion, but a technological reconfiguration aimed at overcoming the time constraint. The modernization project, entrusted to HD Hyundai Samho with delivery expected by 2028, involves replacing two obsolete quay cranes and installing two new rubber-tired gantry (RTG) cranes, integrated into an automated system that reduces maneuvering times by 35% compared to manual processes.
This is not just an operational improvement: it’m a strategic tariff bypass. By reducing the average customs clearance time from three to two working days, HMM gains a direct competitive advantage in terms of cost per TEU for customers who require fast deliveries. The automated system also allows for greater accuracy in load classification, reducing the risk of additional inspections by U.S. Customs authorities.
The choice of 2028 as the final delivery date is not coincidental. It coincides with the entry into service of the new large-capacity containers (14,500 TEU) that will be operational on transpacific routes, ensuring a synergy between ship and terminal. This temporal alignment is crucial: an outdated terminal would have created a new bottleneck upon arrival of the larger ships.
Strategic Leverage of Capacity Control
Investing in WUT represents a strategic leverage for direct control over logistical capacity on a key trade corridor. HMM, through its subsidiary Washington United Terminals Inc., has transformed a simple port partner into an asset that can be optimized without relying on agreements with third parties or local political decisions.
This move is consistent with the Gemini Cooperation model, where Hapag-Lloyd acquired a 25% stake in the APM Terminals Maasvlakte II terminal in Rotterdam to ensure automated access to the European hub. The parallel is not coincidental: both investments aim to create strategic control over critical nodes, reducing dependence on market flows and increasing bargaining power with customers.
The commercial advantage translates into greater pricing flexibility. With a terminal that handles up to 880,000 TEU per year, HMM can offer more stable and predictable service packages, reducing the risk of surcharges and delays. This allows for better planning of COGS and improved forecasting of operating costs.
Impact on Margin and Working Capital
The net effect on operations is measurable: the average reduction of two days in customs clearance time translates into a direct saving on working capital of approximately $180 per TEU, based on an estimate of the average daily cost of immobilization in customs. With 922,000 containers handled by Zim in the second quarter of 2026 (source: FreightWaves), the overall value of the reduction in immobilization is estimated to be around $165.6 million per year.
This is not a marginal saving. It’m a operational leverage that directly influences gross margin and investment capacity in new assets. The automation of the WUT terminal allows HMM to maintain a competitive position even in the presence of tariff increases, because additional costs are offset by an improvement in operating speed.
The conclusion is clear: the enthusiasm for the new investment is not based on future projections, but on the immediate overcoming of a structural constraint. The system stopped pretending to be stable when customs clearance times exceeded the critical threshold of three working days.
