U.S. companies are aggressively frontloading imports from China in a bid to avoid rising tariffs, mirroring tactics first seen during the Trump administration’s trade war in 2018—but on an unprecedented scale.

Frontloading Hits Record Levels

Data from ImportGenius shows that the volume of Chinese exports arriving at U.S. ports in 2025 has more than doubled compared to the peak of 2018. Shipping analysts describe this as “the most imbalanced frontloading spike we’ve ever seen.”

Three major waves of accelerated imports have marked 2025 so far. The first surge began in January, ahead of the so-called “Liberation Day” tariff changes, with containers flowing steadily into U.S. ports. A smaller push occurred between March and April, followed by a dramatic spike in June and July, when U.S. tariff rates on certain Chinese goods dropped to 34%, triggering a 49% increase in shipments.

By contrast, during the 2018 trade war, frontloading peaked later in the year. Between September and October, container imports rose 12.2%, followed by another 22% increase from October to November. While significant at the time, these spikes were modest compared with the surges observed this year.

Indicators Point to a Slowdown

Recent shipping data suggests that imports may soon slow. Ocean freight bookings and container spot rates indicate a cooling trend. ImportGenius analyst Lynn Hughes noted that exports from China to the U.S. dropped 40% between July and August, signaling a potential decline below 600,000 TEUs in the coming months.

Spot rates on key Transpacific routes have also softened. According to Drewry, rates from Shanghai to Los Angeles fell 3% to $2,412 per forty-foot equivalent unit (FEU), while Shanghai to New York dropped 5% to $3,463 per FEU. Drewry noted that the early peak season induced by accelerated purchasing has ended, and U.S. retailers are now scaling back procurement amid a slowing economy and higher tariff pressures.

Implications for Trade and Supply Chains

This surge in frontloaded imports highlights the lengths to which U.S. companies will go to minimize tariff exposure. By accelerating shipments, companies can maintain cost advantages and inventory levels, but the strategy also creates volatility in shipping demand and spot rates.

Analysts warn that the U.S. economy could see a temporary surge in goods availability followed by a slowdown, as the artificial frontloading of imports temporarily inflates supply. Hughes said, “We know what these patterns look like in shipping now, and this is the most extreme frontloading spike we’ve ever observed.”

Looking Ahead

While the initial rush of imports from China is leveling off, the trade war’s ripple effects continue to shape U.S. supply chains. Companies may adjust strategies in the months ahead, balancing the costs of tariffs against the risks of overstocking and supply chain bottlenecks.

The data underscores how sensitive global trade flows remain to policy shifts, and how frontloading remains a powerful, though temporary, tool for mitigating the impact of tariffs.
