On 2026年5月28日, Maersk and DHL jointly issued a freight rate notice. Affected by the ongoing conflict in the Red Sea, tight Asia-Europe sea freight capacity, combined with rerouting around the Cape of Good Hope that has led to longer transit times, pushed the share of small- and medium-batch sensor orders (single batch＜500kg) shifting to air freight up by 37%; during the same period, average air freight rates on routes from Shenzhen/Shanghai to Frankfurt and Amsterdam rose by 22%. This change directly affects companies related to electronic components, industrial sensors, and smart hardware that rely on high-frequency, small-batch cross-border deliveries, as their logistics cost structure and delivery rhythm are now facing substantial adjustment.

Event Overview

According to the official freight rate notice released by Maersk and DHL on 2026年5月28日, the ongoing conflict in the Red Sea has caused a shortage of capacity in Asia-Europe sea freight, and vessels have generally been rerouted around the Cape of Good Hope, extending average transit times by 12–15 days; against this backdrop, the proportion of small- and medium-batch sensor orders (single batch weight＜500kg) choosing air freight increased by 37% compared with the previous month; starting from 5月28日, average rates on air freight routes departing from Shenzhen and Shanghai to Frankfurt and Amsterdam increased by 22%. Although delivery cycles have been shortened to some extent, logistics cost per unit has increased significantly.

Which Market Segments Are Affected

Direct Trading Enterprises

Foreign trade companies primarily exporting finished sensor products, especially those transacting with European end customers under FOB or CIF terms, will be directly impacted by rising air freight costs. Since orders are mostly small-batch and multi-shipment, it is difficult to spread costs through consolidated shipments or full-container sea freight. As the share of air freight increases, freight costs account for a higher proportion of the total contract value, putting pressure on profit margins.

Raw Material Procurement Enterprises

Domestic buyers that need to import key components such as high-precision sensor modules and calibration chips from Europe are also seeing their import logistics costs rise simultaneously. Because such materials are often procured in small batches on a project basis and are highly sensitive to delivery timeliness, air freight alternatives have become a necessity, but the 22% rate increase will feed through to BOM cost calculations and procurement budgeting.

Processing and Manufacturing Enterprises

Companies engaged in sensor OEM/ODM manufacturing will face uncontrollable cost risks if contracts specify delivery schedules and require them to arrange logistics. This is especially true in scenarios where orders are scattered, customers are widely distributed, and single shipments are below 500kg, as originally planned sea freight is forced to shift to air freight, causing actual fulfillment costs to deviate from the basis of earlier quotations.

Supply Chain Service Enterprises

Third-party supply chain service providers offering international logistics solutions, customs coordination, and VMI warehousing and distribution services need to reassess their operating models for small-batch cargo on Asia-Europe routes. A higher proportion of air freight means greater pressure on booking response times, air capacity coordination, security inspection, and customs clearance handoffs, requiring corresponding adjustments to service quotations and SLA commitments.

What Related Companies or Practitioners Should Focus On and How to Respond at Present

Monitor the Update Cycle of Temporary Surcharges from Shipping Lines and Airlines

This 22% price adjustment is the first round of concentrated changes, and the Maersk and DHL notice did not specify a validity period. Companies need to continuously track from 6月 onward whether airlines will add temporary charges such as fuel adjustment fees (FAF) and war risk surcharges (WRS), so as to avoid overlooking newly added cost items when booking cargo space.

Differentiate the Feasibility of Alternative Transport by Sensor Category

Not all sensors must be transported by air. Companies should evaluate category by category, based on factors such as temperature control requirements, ESD protection levels, and whether batteries are included, to determine the feasibility of switching to “sea freight + overseas warehouse pre-positioning” or “sea-rail intermodal transport + regional distribution,” rather than defaulting to the air freight price increase option.

Recalibrate the Logistics Cost Threshold for Small-Batch Orders

The previous internal decision logic that used 500kg as the dividing line between air and sea freight needs to be reviewed. It is recommended to combine current air freight unit prices, sea freight capacity availability, and the time costs caused by rerouting (such as stockout losses and production line stoppages) to build a dynamic calculation model, shifting logistics mode selection from experience-based judgment to quantitative decision-making.

Communicate Contingency Plans on Logistics Terms with European Customers in Advance

If contracts adopt DDP or DAP terms, under which the exporter bears the full freight cost and risk, exporters should proactively explain the impact of the Red Sea situation during negotiations for new orders in 6月, and negotiate a mechanism for sharing freight rate fluctuations (such as setting a freight adjustment clause), to avoid bearing all the pressure of rising costs unilaterally.

Editorial Viewpoint / Industry Observation

Observably, this 22% air freight increase is not an isolated pricing adjustment but a structural signal: the Red Sea crisis has shifted part of the Asia-Europe logistics load from sea to air for time-sensitive, low-weight cargo — and the cost is now being priced into the market. Analysis shows that the 37% rise in air shipment ratio for sensor consignments reflects a threshold crossing, where reliability and lead time have overtaken cost as the primary decision driver for many SMEs. It is more accurate to understand this as an early-stage supply chain recalibration rather than a short-term anomaly; sustained conflict would likely deepen air freight dependency for high-value micro-components, making real-time freight intelligence and multi-modal routing capability increasingly core competencies.

Conclusion: this increase in air freight costs is a concrete manifestation of geopolitical risk in the Red Sea transmitting into the midstream of the Asia-Europe supply chain. Its significance lies not in the one-time price adjustment itself, but in revealing the vulnerability node of small-batch, high-value-added electronic materials within the global logistics network. At present, it is more appropriate to understand this as a stress test——what it examines is the precision of a company’s response to sudden logistics cost fluctuations, rather than simply its cost-bearing capacity.

Source note: The main information comes from the joint freight rate notice issued by Maersk and DHL on 2026年5月28日. Further developments regarding the pace of subsequent price adjustments, actual delay data for rerouted voyages, and changes in customs clearance efficiency on the European side still require continued observation of updates from official channels.
