How Did US-China Trade Tensions Impact Shipping Volumes in Early April 2025?
In early April 2025, US-China trade tensions led to a drastic drop in container bookings, particularly after the April 2 announcement of a 54% total tariff on Chinese imports. Data from logistics platform Vizion shows a significant contraction in global trade lanes during the first week of April (April 1–8) compared to the previous week (March 24–31), with US-China maritime routes experiencing the most severe impact.
- Global TEU bookings fell by 49%
- US imports dropped 64%
- US exports decreased 30%
- US imports from China plunged 64%
- US exports to China declined 36%
This decline follows the April 2 announcement of a 10% baseline tariff on all US imports, combined with a 34% additional tariff on Chinese goods, effectively creating a 54% total tariff on Chinese imports.
The fallout underscores growing volatility in international trade and maritime logistics. With tariffs disrupting containerised trade flows, global supply chains now face higher costs, longer delays, and shifting alliances in the shipping industry.
What Happened to Freight Rates After the New Tariffs Were Announced?
After the new tariffs were announced, shipping costs experienced an unexpected spike just before their implementation, despite expectations that weaker demand would drive freight rates down. This brief surge in container rates was observed by April 1, 2025, across key routes.
By April 1, 2025, container rates surged:
- China to US East Coast: up 9% to $322/FEU
- China to US West Coast: up 16% to $383/FEU
- Air freight from Vietnam to the US rose 8%, and from China to the US by 5%
According to Xeneta, a global freight market intelligence platform, spot container rates from the Far East to both US coasts jumped ahead of the tariff implementation. However, these same spot rates are still 43% to 49% lower than they were at the start of 2025.
“Liberation Day will not bring a sense of freedom to carriers caught in the crossfire of tariffs,” said Peter Sand, Chief Analyst at Xeneta.
Sand warned that shipping companies and US importers face major challenges in negotiating long-term freight contracts starting May 1. He noted that the ongoing uncertainty in US-China trade relations makes supply chain planning increasingly difficult.
While the tariff surge briefly inflated costs, the broader trend remains downward, with spot rates expected to continue falling due to global overcapacity and slowing trade flows.
Why Did Shipping See a ‘Frontloading’ Surge Before the Tariffs?
Shipping experienced a ‘frontloading’ surge before the tariffs because many U.S. importers strategically rushed orders in early 2025. This behavior created a sharp uptick in ocean freight bookings during Q1, as businesses aimed to beat the April 2 tariff deadline and avoid the impending higher costs.
However, once the tariffs took effect, booking volumes plummeted, signalling a rapid contraction in demand—a trend clearly reflected in recent shipping data.
Which Industries Are Most Affected by the New Tariffs?
The new tariffs are impacting various industries differently, with some sectors absorbing the shock more severely than others. Here’s a breakdown of which industries are most affected:
- E-Commerce — Very High Impact
Platforms like Shein and Temu are directly affected by the removal of de minimis tax exemptions for orders under $800. Their cost structure is now under intense pressure. - Pharmaceuticals & Medical Devices — High Impact
These sectors prioritise speed and reliability. While they can absorb higher costs, tariffs still disrupt supply chain flows and budgeting. - Technology & Data Centers — High Impact
Imports of servers, networking gear, and AI hardware have surged, with U.S. firms rushing to secure critical infrastructure before tariffs drive prices up. - Fast Fashion — High Impact
With low price points and razor-thin margins, losing de minimis protections is a major blow. Tariffs could multiply landed costs, threatening profitability. - Toys & Games — Medium to High Impact
Industry players like Steve Jackson Games have warned that 54% tariffs could devastate smaller manufacturers and niche brands.
How Are Shipping Lines Responding to Current Trade Challenges?
In response to escalating U.S.-China trade tensions and reduced demand from new tariffs, global shipping lines are rapidly adapting their operations. With freight volumes declining, particularly on crucial routes such as the trans-Pacific, carriers are implementing aggressive capacity management strategies to maintain efficiency and navigate the challenging environment.
1. Cancellations, Route Cuts, and Strategic Adjustments
The most immediate response has been a wave of blank sailings—scheduled voyages that are canceled to reduce excess capacity.
- A total of 47 blank sailings have been announced, heavily concentrated on trans-Pacific and Asia-Europe trade lanes.
- 43% of cancellations are on trans-Pacific routes, mirroring the steep drop in U.S. imports from China and broader Asia.
- HLS Group alone has logged 80 cancellations from China, and the ONE Alliance has indefinitely suspended a major route originally set to resume in May.
2. Vessel String Reconfigurations
Shipping lines are also modifying or scrapping vessel strings—the sequence of ships operating on a given route. This helps align sailing schedules more closely with reduced demand and port congestion scenarios.
3. Subtle Capacity Controls: Slower, Smaller, Smarter
Beyond outright cancellations, carriers are turning to operational tweaks to manage excess capacity without idling fleets:
- Slow steaming: Reducing sailing speed to stretch transit times and absorb capacity.
- Skipping ports: Extending voyage timelines by omitting certain stops.
- Maintenance buffering: Placing ships in dry dock under the guise of scheduled service.
- Downsizing vessels: Using smaller ships on underperforming routes.
4. Downtime Remains Low
Despite the downturn, only 0.2% of the global container fleet is currently idle. This shows that rather than leaving ships docked, carriers are using speed reductions, route tweaks, and flexible scheduling to absorb lower volumes and maintain fleet utilisation.
What is the USTR’s Proposed $1 Million Port Charge and Its Impact?
Beyond the current economic turbulence, the shipping sector is now confronting new regulatory challenges, specifically the Office of the United States Trade Representative (USTR)’s proposed $1 million port entry charge for vessels built in China. This measure, presented as a national security initiative, aims to decrease U.S. dependence on Chinese-built ships.
But the backlash has been swift.
U.S. exporters, port authorities, and logistics unions argue the proposal would backfire, raising operating costs, disrupting trade flows, and risking domestic maritime jobs. Critics warn it could hamper U.S. exports just as shippers are already dealing with falling demand and tariff-driven uncertainty (Reuters).
Are Freight Rates Rising or Falling Amidst Trade Tensions?
Amidst ongoing trade tensions, freight pricing is experiencing complex and diverging trends, making it difficult to determine if rates are consistently rising or falling. This flux is evident through contrasting dynamics across different transport modes and even between various shipping indices.
Ocean Freight: Mixed Signals
- The Shanghai Container Freight Index (SCFI) has fallen 17% since January 2025, and over 55% since its December 2024 peak, now hovering at stabilised, lower levels.
- Meanwhile, the Drewry World Container Index reports a spot rate of $5,318 per 40ft container, up sharply from $1,536 a year ago.
This discrepancy suggests a split market: rising rates on specific high-demand lanes, possibly due to pre-tariff frontloading, versus a general downward trend as volumes fade.
Air Freight: Demand Surge Drives Spike
- Global air cargo spot rates surged 37% in March alone, hitting $4.14/kg, the highest level of 2025.
- The China–U.S. route mirrored the global average with a 37% increase, while the Europe–U.S. lane saw a smaller 7% rise to $2.61/kg.
This spike is largely driven by companies in technology, pharmaceuticals, and data infrastructure, rushing to air freight goods before tariffs took effect in April—especially on China-origin shipments.
Why Does Port Congestion Continue Even with Lower Shipping Volumes?
Despite a noticeable drop in container volumes on U.S.-bound routes, port congestion continues to persist globally. This ongoing issue suggests a fundamental mismatch between existing port infrastructure readiness and the overall fluidity of the supply chain, leading to elevated congestion levels even with reduced traffic.
- Global port congestion exceeds 10%, with over 20 vessels waiting on average at major ports.
- Europe is a hotspot: over 935,000 TEUs are stuck at Northern European and Mediterranean ports, making up 32% of global backlogs.
Most Severely Affected Ports:
Istanbul, Singapore, Chittagong, and Shanghai remain bottlenecks.
Specific waiting times:
-
- Algiers: Improved, now 5 days (down from 7).
- Djen-Djen: Average 3 days, peaking at 14.
- Bejaia: Up to 8 days.
- Cape Town: 8–10 days, affected by winds.
- Durban: Stable at 1 day.
Bright Spots:
- Congestion has eased at Hamburg and Rotterdam.
- PSA Antwerp has improved flow by cutting its export delivery window by 5 days, helping streamline outbound movement.
How Are Ports and Businesses Handling Current Shipping Disruptions?
Ports and businesses are grappling with significant ongoing disruptions, primarily driven by the sharp drop in container traffic to North America. This challenge is compounded by volatile freight rates and inconsistent port congestion, collectively straining operational capabilities and strategic planning for all stakeholders.
- Ports must adapt to shifting cargo flows, driven by changing trade patterns and route cancellations.
- U.S. businesses are facing supply chain uncertainty, with challenges in planning inventory, managing costs, and selecting reliable logistics partners.
Adding to the complexity, negotiations for new long-term ocean contracts, effective May 1, are forcing importers to make high-stakes decisions amid unstable market conditions.
What Are the Key Takeaways for Navigating Global Shipping Adjustments?
To navigate the current era of adjustment in global shipping, it’s crucial to understand the fundamental reset triggered by U.S.–China trade tensions and new tariffs. Key takeaways for businesses and stakeholders include recognizing several dominant trends that are reshaping the industry:
- Carriers are cutting capacity through blank sailings and slow steaming.
- Air freight surging temporarily as shippers race to beat tariff deadlines.
- Ocean spot rates are diverging across indices and trade lanes.
- Port congestion is persisting in Europe, Asia, and parts of Africa despite falling volume.
Across the board, uncertainty is the dominant force, pressuring stakeholders to stay agile, rethink sourcing, and diversify logistics strategies in a volatile landscape.
