How Global Shipping Lines Are Responding to New U.S. Port Fees

The international shipping industry is undergoing significant adjustments as the United States prepares to impose new port fees on Chinese-built or Chinese-linked vessels. These measures, scheduled to take effect in October 2025, are designed to reduce reliance on China’s shipbuilding sector and strengthen America’s maritime position. Carriers, shippers, and exporters are already taking steps to adapt to the policy, which is expected to reshape trade routes and cost structures in the months ahead.

Why the Policy Matters

Earlier this year, U.S. trade officials announced plans to levy substantial charges on vessels built in China or tied to Chinese ownership. The original proposals suggested fees of up to $1.5 million per port call, with scenarios that could escalate to more than $3 million per visit for certain ships. Although the final framework has been scaled back, the intent remains clear: encourage cargo to shift toward U.S.-flagged and U.S.-built vessels, while discouraging the dominance of Chinese shipyards in global trade.

However, the U.S. shipbuilding industry currently lacks the scale to fill such a gap, raising concerns among exporters, importers, and port operators who fear higher costs and operational disruptions.

Reaction Across the Industry

The announcement triggered immediate resistance from a wide spectrum of stakeholders. Farmers, exporters, dockworkers, and shipping companies warned that the measures could increase freight rates, slow down cargo handling, and put jobs at risk in port communities. One industry group estimated that container costs could rise by several hundred dollars per unit, placing additional pressure on supply chains already dealing with volatile fuel prices and shifting global demand.

Despite these concerns, carriers are not waiting to see how the situation unfolds. They are actively redeploying vessels, redesigning service loops, and preparing to operate within the new regulatory landscape.

How Carriers Are Adjusting

CMA CGM’s Redeployment Strategy

French carrier CMA CGM has emphasized its ability to adjust quickly. With fewer than half of its 670 vessels built in Chinese shipyards, the company has enough flexibility to reassign ships and avoid excessive exposure to fees. Executives stated that the fleet’s composition allows them to maintain service levels without passing significant additional costs to customers.

Maersk’s Avoidance Approach

Industry leader Maersk has taken a more straightforward position. The company confirmed that it will exclude Chinese-built ships from U.S. trade lanes rather than incur the new charges. By redesigning services in this way, Maersk expects to keep costs under control while ensuring clients are not burdened with additional surcharges.

Broader Route Shifts

Other container lines are also reevaluating their networks. Some alliances have already reduced the number of China-to-U.S. sailings, while others are rerouting traffic to minimize the number of Chinese-linked vessels calling at American ports. These adjustments reflect the highly interconnected nature of global shipping, where a single policy can ripple across multiple trade lanes.

Anticipated Impact

The ripple effects of the policy will extend well beyond the shipping industry:

• Importers and exporters should anticipate higher freight costs as carriers incorporate compliance expenses into rate structures.

• Ports and terminals may face scheduling challenges, as lines consolidate calls or shift services to minimize fee exposure.

• Global shipbuilders in South Korea and Japan are likely to benefit, as orders shift away from Chinese yards toward alternative suppliers.

• U.S. shipbuilding could see increased investment, though experts caution that scaling capacity will take years, not months.

Ultimately, the adjustments may raise shipping costs in the short term while testing the resilience of U.S. supply chains.

Looking Ahead

The upcoming changes underscore how closely trade policy and global shipping are intertwined. Carriers are already restructuring their networks to navigate new requirements, while shippers and exporters prepare for potential price increases and logistical challenges. Although the policy’s long-term impact on U.S. shipbuilding remains uncertain, its short-term effect is clear: the redirection of fleets, altered service patterns, and a recalibration of costs across the global maritime system.

As the October deadline approaches, the question is not whether the industry will adapt, but how smoothly it can transition. For carriers, the challenge will be maintaining reliability and efficiency while working within the new framework. For shippers, the task will be finding cost-effective ways to move cargo in an evolving trade environment.

One thing is certain: the global shipping landscape is entering a new phase, where strategic fleet deployment and careful cost management will define competitiveness.
