March Airfreight Surge Sets Stage for Further Growth as US-China Trade Tensions Ease

Airfreight markets posted a record performance in March, with particularly strong activity on Asia, US, Europe and UK trade lanes. The surge, driven by shippers front-loading cargo ahead of anticipated US tariffs, has provided a benchmark for what could follow in the months ahead as recent tariff reductions between the US and China hint at a renewed spike in activity.

According to IATA, global demand measured in cargo tonne-kilometres rose by 4.4% year-on-year, with international cargo traffic increasing by 5.5%. Capacity, meanwhile, increased by a similar margin, helping to stabilise load factors despite the sudden surge in volumes. Asia-Pacific carriers led growth with a 9.6% rise in demand and an 11% increase in available capacity. North American airlines recorded a 9.5% increase in volumes, while European carriers posted a more moderate rise.

Asia-North America remained the largest and fastest-growing trade lane by market share, as exporters sought to avoid the sharp rise in tariffs. The Europe-North America route also experienced strong activity and was the busiest overall in March, underpinned by steady intra-European demand which grew by 2%.

The operating environment provided further stimulus, with world industrial output and global trade volumes expanding by just under 3%. Falling energy costs provided additional support, with jet fuel prices down for the ninth consecutive month. Inflation rates also stabilised across key markets, providing additional certainty for international shippers. China’s deflationary environment also showed signs of softening, with the rate improving to just below zero.

The result was a sharp escalation in demand from sectors that rely on rapid supply chains and cannot risk ocean freight delays. Electronics, high fashion, automotive and perishable goods were among the leading commodities contributing to the increased volumes.

The extraordinary March performance may not remain an isolated event. The recent temporary US-China tariff reduction has the potential to trigger another wave of increased airfreight activity.

While the extent of future growth will depend on how negotiations between the world’s two largest economies unfold, the easing of tariffs has already bolstered market sentiment.

However, market analysts note that after the March peak, demand may return to more typical seasonal levels in the short term, particularly as capacity has increased by over 6% on international routes, offering more space for shippers. Yet, the fundamental reliance on airfreight for high-value and time-critical shipments between Asia, the US, Europe and the UK remains unchanged.

Should trade relations between the US and China continue to thaw, the market could be poised for another significant uplift in volumes. The key will be whether the current political stability translates into sustained confidence among exporters and freight forwarders across these critical trade lanes.

Houthis 1440x1080 1

Trump’s Red Sea Gambit

A dramatic shift in the Red Sea shipping crisis may be underway following US President Donald Trump’s announcement that Houthi militants have agreed to halt their campaign against commercial vessels.

His declaration has sparked hopes of restored freedom of navigation through one of the world’s most vital maritime corridors. However, conflicting signals from the Houthis and persistent security concerns leave the industry navigating uncertain waters.

Trump’s comments, made ahead of a high-profile meeting with Canadian Prime Minister Mark Carney on May 6, suggested that after months of military escalation, a breakthrough had been reached. The President claimed that the Houthis had “capitulated” and would cease missile and drone strikes on commercial shipping. He pledged that US airstrikes on Yemeni targets would also end in response.

Omani diplomatic sources have echoed the ceasefire narrative, pointing to coordinated discussions that purportedly yielded a de-escalation agreement and a commitment to non-aggression on both sides.

Yet, the Houthis have swiftly rejected Trump’s portrayal, asserting that no formal truce exists. According to Houthi representatives, the group’s military stance remains unchanged, particularly in relation to Israel, and any pause in attacks was a tactical decision rather than the result of concessions.

This ambiguity undermines confidence among major container lines, many of which continue to avoid Red Sea routes due to crew safety concerns and inflated insurance premiums.

If hostilities genuinely subside, container carriers could begin rerouting vessels back through the Suez Canal. Around 10% of global container capacity has been absorbed by the longer, costlier voyages around southern Africa. A return to Suez would free up this latent capacity, potentially exacerbating overcapacity issues already pressuring the industry. With the container vessel order book standing at about a quarter of the current fleet size, the market faces mounting risk of supply-demand imbalance.

Freight rates, which surged earlier due to the Red Sea crisis, could spike again if carriers resume shorter transits en masse, before softening once schedules settle back down. And while rate increases and extended lead times could finally see some relief the resulting supply-side glut may create new headaches for the container shipping lines.

Port activity along the Red Sea remains subdued, with volumes reportedly down by around half compared to last year. A reliable and lasting resolution could rejuvenate regional trade flows, benefiting not only global carriers but also Gulf-based shippers and transhipment hubs that have been cut off from direct east-west routes.

For now, the shipping industry remains caught between political theatre and on-the-ground reality. Whether Trump’s announcement marks the dawn of stability or another premature claim depends on actions in the Bab al-Mandab, not words in Washington.

The situation in the Red Sea remains unpredictable and liable to change. If your business relies on consistent global shipping operations, this is the perfect time to review your contingency plans and explore flexible alternatives.

Hidden threat to exporters

Northern Europe’s Ports Struggle with Congestion Amid Network Shifts

Ports across Northern Europe are grappling with rising congestion, causing widespread delays and operational disruption. A confluence of industrial action, infrastructure strain, inland transport bottlenecks and the rollout of new shipping alliances is overwhelming terminals, with no immediate relief in sight.

Container volumes have surged at key gateways such as Antwerp-Bruges, Bremerhaven, Rotterdam, and Felixstowe, with waiting times and yard occupancy levels climbing.

Antwerp is experiencing yard utilisation at 96%, with reefer plugs over capacity at 112%.

Nearly half the vessels arriving are waiting for berths, and 52 more containerships are en route. Berthing delays are being exacerbated by residual backlogs following strikes at the end of March, and the port has reduced its export delivery window to five days to help ease pressure.

In Germany, Bremerhaven is seeing similar strain, with nearly 30% of vessels waiting for berths and inland rail disruptions further complicating the situation. Landslides and line closures near Hannover forced lengthy rail detours, impacting traffic to and from major ports including Hamburg, Rotterdam and Duisburg. These rail delays are causing a cascading effect across Northern Europe’s inland logistics.

The Netherlands is also under pressure, with unresolved automation disputes in Rotterdam contributing to labour-related delays. In France, strikes at Le Havre have eased for now during ongoing negotiations, but the risk of renewed action remains high.

The UK is not immune. Felixstowe, London Gateway, and Southampton are all dealing with congestion as vessel diversions from continental ports push volumes higher.

Multiple factors are compounding the problem. The phasing in and out of new alliance schedules—particularly by Maersk, MSC, and Hapag-Lloyd—is disrupting established flows and increasing port calls. Simultaneously, low water levels on the Rhine are limiting barge capacity, shifting more freight to already stretched rail and road networks. Labour shortages, especially during public holidays, have further constrained operations.

With delays mounting, carriers are urging shippers to collect containers promptly and to avoid early delivery of exports. Some terminals, like PSA Antwerp, have shortened delivery windows to reduce yard congestion. Carriers are implementing contingency plans on a vessel-by-vessel basis and may introduce congestion surcharges to offset rising operational costs.

Industry forecasts suggest that congestion could persist for another three to four months, until alliance network changes bed in and volumes normalise. In the meantime, importers and exporters should prepare for longer lead times, increased costs, and fluctuating capacity at Europe’s busiest container ports.

With congestion disrupting major European gateways, our flexible contingency plans are keeping cargo moving, rerouting through alternative ports and opening up new entry points.

To reduce delays and protect your supply chain, share your shipping forecasts early so we can act fast and proactively manage risks.

New Tariffs and the End of De Minimis

On 2 April 2025, President Donald J. Trump announced sweeping new tariffs, targeting approximately 60 countries, with China singled out for the most severe action. In response to retaliatory tariffs from Beijing, the United States escalated its own duties, ultimately imposing a 125% tariff on all imports from China, Hong Kong, and Macau, in addition to previously existing tariffs.

While the White House has not made extensive public statements on the topic of de minimis imports – the long-standing policy allowing goods valued under $800 to enter the U.S. duty-free – key guidance released on 2 and 8 April confirms that this exemption will soon be withdrawn for goods from China and Hong Kong.

Escalation of U.S. Tariffs on China
The first of the new tariffs took effect on 4 February 2025, when a 10% duty was introduced on top of the existing Section 301 tariffs. This was increased to 20% on 4 March, and then, on 2 April, President Trump announced a 34% reciprocal tariff, which included a new 10% baseline tariff applicable to all countries starting 5 April.

However, after China retaliated with increased tariffs on U.S. exports, the White House raised the China-specific tariff to 84% on 8 April, and then to a staggering 125% on 9 April. 

This final rate became effective at 00:01 ET on 10 April. These duties are stackable, meaning that in many cases, importers will face a total duty burden of around 145%, factoring in earlier Section 301 tariffs and the new reciprocal tariffs.

De Minimis Policy Changes for Chinese Imports
The de minimis exemption, which allows shipments valued at or below $800 USD to enter the United States without duties or import taxes, is being formally eliminated for goods originating from China and Hong Kong, effective 2 May 2025 at 00:01 ET.

This change follows a period of confusion that began on 1 February, when the White House first announced the end of de minimis for Chinese-origin shipments. 

Implementation on 4 February resulted in significant logistical disruptions, including a temporary halt in parcel acceptance by the United States Postal Service (USPS). The policy was reversed just one day later, on 5 February, to give U.S. authorities time to prepare for full enforcement.

Now, with updated executive orders on 8 April and 9 April, the de minimis exemption will definitively end for China and Hong Kong on 2 May. The administration is also considering extending these rules to Macau.

Starting on that date, goods valued under $800 from China and Hong Kong will be subject to a duty calculated at 120% of the item’s value, and a postal fee of $100 per package. 

The postal fee will rise to $200 on 1 June 2025. These amounts were increased from earlier planned levels of 30% duty and $25/$50 postal fees through the two April executive orders.

Additionally, the exemption will no longer apply to low-value goods shipped through couriers or freight companies—not just postal shipments—ensuring broad application across all shipping channels.

What’s Next?
While the de minimis threshold remains in place for most other countries, both the White House and members of Congress are reportedly reviewing broader changes to this policy. 

For now, the key changes apply specifically to China and Hong Kong, but the political momentum suggests the U.S. may tighten or eliminate de minimis privileges more broadly in the near future.
