SiC/GaN Power Module Air Freight Delays Mount into Q3 2026 for EV Sector
Air freight logistics for critical Silicon Carbide (SiC) and Gallium Nitride (GaN) power modules, essential for Electric Vehicle (EV) drivetrains and charging infrastructure, are experiencing growing delays. This trend, affecting major producers in Europe and Asia, is projected to intensify into Q3 2026, posing challenges for EV production schedules.
Procurement engineers in the Electric Vehicle (EV) sector are contending with increasing air freight delays for Silicon Carbide (SiC) and Gallium Nitride (GaN) power modules. These advanced components are critical for enhancing the efficiency and power density of EV drivetrains, inverters, and fast-charging systems. The current logistical bottlenecks are primarily impacting shipments originating from key manufacturing hubs in Europe, particularly Germany and France, and from Southeast Asian nations where many power module assembly and testing facilities are located. These delays are exacerbated by continued high demand for air cargo space for other high-value electronics and persistent labor shortages at major international air hubs.
While sea freight offers a more cost-effective alternative, the time-sensitive nature of EV production lines and the high value-to-weight ratio of SiC/GaN modules often necessitate air transport. The current delays, averaging 2-3 extra days for transit and customs clearance, are disrupting just-in-time inventory strategies and forcing EV manufacturers to re-evaluate their component buffer stocks. Some manufacturers are reporting extended delays of up to a week for specific high-power SiC modules, leading to potential production line interruptions if not proactively managed.
Industry analysts attribute a significant portion of the issue to a confluence of factors, including the global expansion of diverse high-tech industries competing for limited air cargo capacity, coupled with geopolitical pressures that occasionally result in rerouting and longer flight paths. This has led to unpredictable capacity fluctuations and increased spot rates for critical routes. Freight forwarders are actively working with airlines to allocate dedicated cargo space, but the structural constraints of airport infrastructure and labor markets remain significant challenges.
Looking ahead to Q3 2026, the situation is not expected to significantly improve. The projected ramp-up in EV production volumes globally will likely place even greater strain on air logistics networks. Procurement teams are advised to engage in early booking for critical SiC/GaN module shipments, explore alternative routing options, and increase safety stock levels to mitigate the risk of assembly line slowdowns. Long-term strategies may include diversifying supplier locations to reduce reliance on single-region logistical choke points.
