Negotiating transpacific uncertainty amid summer surge

Transpacific trade lanes are experiencing a volatile blend of opportunity and uncertainty, as US importers race to beat looming tariff deadlines while air and ocean carriers grapple with shifting demand patterns.

Temporary suspensions of key tariffs on Chinese and reciprocal imports have triggered a short-term import surge by sea and prompted early restocking efforts via air. However, both air and ocean markets face potential disruption when these reprieves expire in July and August.

On the ocean side, the summer import season has gained momentum, with US retailers significantly increasing their forecasts for containerised goods through August. July volumes are now expected to reach 2.13 million TEUs, a 20% upgrade from previous projections, as shippers rush to bring goods in before tariff hikes potentially resume. Similarly, August forecasts are up by nearly 9%, reflecting continued front-loading of inventory.

Yet this spike may be short-lived. Forecasts for September and October show a sharp drop in volumes, nearly 22% below the same period last year, as uncertainty clouds the outlook for Q4. Retailers are adjusting their holiday planning accordingly, expecting the seasonal peak to arrive earlier and coincide with back-to-school demand.

In air freight, signs of a modest recovery are emerging on the transpacific lane. General cargo volumes are rising, aided by seasonal tech launches, pharma shipments, and perishables, as well as urgent moves triggered by ocean capacity constraints. Air carriers are cautiously reinstating freighter capacity that had previously been diverted to other trade lanes, with recent data showing an 11% increase in lift on Asia–North America routes.

However, this revival remains fragile. The collapse in eCommerce volumes, once responsible for half of all China–US air freight, is dampening demand, following recent changes to US de minimis thresholds and flat-rate fees on low-value parcels. Although airlines are optimistic that eCommerce will remain a core air cargo driver over the long term, its immediate contribution has diminished, affecting space availability and rates.

Airlines are responding with a balancing act, gradually adding capacity while monitoring how tariff policies evolve. Spot rates on the China–US lane have already risen 14% since early May, and rates are likely to climb further through June as end-of-quarter shipments and tariff-related demand bottleneck available space. Shippers are being advised to book two to three weeks in advance and consider alternative routings through Southeast Asia to mitigate risk.

Looking ahead, much hinges on whether tariff reprieves are extended or allowed to expire. The political signals from Washington and Beijing in the coming weeks will heavily influence whether shippers continue front-loading or pause amid uncertainty. Manufacturers are also beginning to adjust sourcing strategies in response to the long-term tariff environment, with some high-tech production shifting from China to South Asia.

While current disruptions are reshaping transpacific flows, long-term confidence remains high. Industry leaders at Boeing and Airbus maintain forecasts of steady 3–4% annual air cargo growth over the next two decades, citing enduring demand fundamentals.

For now, agility is essential. Whether by sea or air, transpacific freight stakeholders must remain responsive, proactive and well-informed as short-term pressures play out against long-term structural shifts.
