Tariffs Spark Record-Breaking Import Volume at West Coast Ports

July proved to be a historic month for U.S. West Coast ports, as PORT OF LOS ANGELES and PORT OF LONG BEACH not only witnessed unprecedented import volumes—but also laid bare how tariff uncertainty has scrambled shipping patterns across the global supply chain.

At Los Angeles, the port moved 1,019,837 TEUs in July—the highest monthly total in its 117-year history—marking an 8.5% year-on-year increase. Impressively, 543,728 of those TEUs were loaded imports, a new high-water mark. The Port of Long Beach experienced a surge as well, marking its busiest July in over a century. This flurry of activity stems from shippers rushing to beat expected tariff hikes, with President Trump recently pushing out higher duty deadlines from August to November.

But the windfall may be short-lived. Behind these record figures lies growing concern about the broader impact of price shocks and trade volatility. According to the Yale Budget Lab, tariffs could cost U.S. households $2,400 annually through higher prices on goods like apparel and leather, while also projecting nearly 500,000 job losses and a 0.5 percentage point drop in GDP by year-end.

Strategic Preloading, But a Volatile Forecast

The industry's response to opaque tariff signaling has been a tactical "front-loading" of goods—evident in Los Angeles and Long Beach’s July tally—but rosy figures now may mask the turbulence to come. BIMCO data reveals volume swings of over 14% YoY in early 2025, followed by a sharp 9.2% drop in May–June as the tariff threat loomed.

This frenetic activity pushed freight spot rates upward in earlier months, but July’s stability in rate trends and shipping contracts now signals a probable slowdown ahead.

What Comes Next for Shipping Stakeholders

Despite July’s boom, the outlook is increasingly fraught. With trader behavior swinging between frenzy and freeze, fragmented forecasts are emerging. The Global Port Tracker projects import volume declines—5.6% annually overall, and steep 19–21% dips in key fall months like September through November.

Moreover, shipping players face compounding friction: Washington’s simultaneous threats of reciprocal tariffs, port-origin fees, and undefined policy shifts add logistical strain across all corridors. Given the aggressive reshaping of trade routes and freight procurement timelines, carriers, terminal operators, and compliance teams must brace for volatility through H2 2025—and beyond.
