From Shipper Strategy to Blank Sailings: How the Industry is Reacting to Tariff Pressures
Tariff Uncertainty Disrupts Booking Trends Amid Heightened Trade Tensions
Recent booking data provides an early indication of how global shippers are strategically adjusting in response to rapidly evolving tariff policies.
A pronounced surge in Q1 2025 activity, followed by a steep decline in early April, underscores the agility with which supply chains are adapting to geopolitical and regulatory disruptions.
A longitudinal view of U.S. import booking volumes shows significant volatility over the past five years. The 2021 pandemic-era peak was followed by a contraction throughout 2022. Recovery began in 2023, strengthening through 2024 and peaking in early 2025.
However, the momentum proved short-lived. Booking volumes fell 20% from January highs in March 2025, though year-over-year growth remained at 30%. This suggests strategic front-loading by shippers, anticipating tariff hikes, and pulling forward volumes to mitigate potential cost impacts.
The week-over-week data between March 31 and April 8, 2025, reveals a sharp contraction:
These declines closely follow critical policy announcements: President Trump announced new tariffs on April 2, followed by retaliatory measures from China. The result was a widespread booking freeze as companies paused to reassess freight flows, cost exposure, and operational risk.
Zooming in on product-level trends between March 31-April 6, 2025, and the prior week (March 24-30) reveals sharp booking declines across several categories:
These are mainly discretionary or seasonal categories, often the first to react to rising costs, demand shifts, or trade policy changes. Many of these goods also fall under one of many tariff adjustments, making them more sensitive to uncertainty and pricing volatility in the short term.
This data highlights a recurring theme: shippers are increasingly responsive to forward-looking policy signals, acting decisively before disruptions hit the ports.
The broader implication is a growing reliance on predictive logistics intelligence as a competitive necessity. With a 90-day pause in tariff implementation from other trade partners, the remainder of 2025 will likely be defined by episodic demand surges, compressed procurement cycles, and active reevaluation of sourcing strategies as the global supply chain recalibrates to ongoing trade realignment.
Carriers Cancel Sailings as Demand Dips on Asia-Europe & Transpacific Routes
Ocean carriers are increasingly pulling scheduled sailings from Asia to the U.S. and Europe, signaling a proactive response to declining demand and tariff-driven market shifts. According to maritime data provider eeSea, a notable rise in blank sailings is underway for vessels originally scheduled to arrive at European ports throughout April, May, and June.
“Blank sailings are ramping up across all major trade lanes,” said Simon Sundboell, CEO of eeSea. “While not yet at critical levels, the current pace marks a meaningful uptick in capacity withdrawals.”
Blank sailings (deliberate cancellations or delays of scheduled voyages) are a strategic lever that ocean carriers use to balance supply with anticipated demand. These decisions often force exporters to rebook on alternate sailings, creating potential bottlenecks in outbound flows and complicating inventory planning.
The trend is particularly pronounced in the U.S. market, where the National Retail Federation projects a 20.5% drop in retail container imports for May. This decline follows a wave of front-loaded shipments earlier in the year as importers sought to preempt anticipated tariff increases. With inventories temporarily elevated, retailers are now scaling back new orders, reducing near-term booking demand across key lanes.
Drewry predicts that the frequency of sailings will decline over the next five weeks, with approximately 88% of weekly departures happening as scheduled.
Implications for Importers and Supply Chain Managers:
As carriers rebalance networks in response to shifting economic signals, supply chain professionals should remain vigilant. Monitoring schedule changes, maintaining flexible routing strategies, and coordinating closely with your forwarders will be essential to managing volatility through Q2.
