Asia-Pacific to US air cargo demand ran 17% above year-ago levels in mid-September, and volumes will rebound further as factories reopen after Golden Week, freight forwarder CH Robinson said in a market update.

Technology shipments — servers, semiconductors and other electronics — remain the strongest demand driver on the transpacific, with new consumer-device launches adding a fresh layer of time-sensitive freight. General cargo should lift more gradually as manufacturers and retailers build inventory for early Black Friday and Cyber Monday promotions.

"Asia Pacific-to-US demand was already running 17% above last year in mid-September, with several technology-heavy origins showing stronger gains," the US forwarder said.

What's driving the imbalance?

E-commerce, the air cargo demand engine of recent peak seasons, will play a smaller role this year because of tariff changes in the US and Europe. That shift concentrates peak-season pressure in tech and time-sensitive verticals rather than spreading it across parcel flows.

CH Robinson expects Asia-origin pricing to firm "more noticeably" from mid-October, particularly on transpacific lanes where technology and new-product freight dominate. Conditions will diverge gateway by gateway.

"Conditions will vary by origin as cargo mix, gateway demand, airline allocations, and freighter schedules shape available capacity," the company said.

Will Europe-bound shippers lose freighter options?

That is the central risk CH Robinson flagged. If carriers redeploy freighter aircraft and belly space toward high-yielding US-bound lanes, shippers moving goods to Europe or within Asia could face fewer workable options — even where underlying demand has not surged.

"If more freighter capacity is directed toward US-bound services, shippers moving freight to Europe or within Asia may see fewer workable options even when demand on those lanes has not increased significantly," CH Robinson explained.

The forwarder added that "airlines often respond to concentrated demand by adjusting aircraft deployment, schedules, and allocations toward lanes where booking activity is strongest." Passenger belly space can absorb a large share of general freight but cannot substitute for freighters across every commodity, the firm noted.

Which origins are most exposed?

CH Robinson argued the Asia–Europe trade is less broadly pressured than the transpacific, but individual technology-heavy origins could still tighten. China, Southeast Asia and India need separate evaluation rather than a single "Asia" outlook.

"China, Southeast Asia, and India should therefore be evaluated separately. Local cargo mix, aircraft type, gateway performance, and airline schedules can produce very different booking conditions from one origin to another," the forwarder said.

Other swing factors include typhoon-season disruptions and modal transfer from ocean shipping when container operations falter — a pattern that has coloured recent peak seasons.

The forwarder cautioned that if general-cargo flow stays measured and post-holiday demand concentrates mainly in technology and time-sensitive freight, "booking limitations are more likely to remain origin- and departure-specific rather than spreading broadly across Asia."

What should shippers watch next?

• Mid-October transpacific rate moves out of tech-heavy origins
• Airline freighter schedule changes, particularly US-bound redeployments
• Typhoon-related disruption across Asia operations
• Tariff effects on e-commerce flows into the US and Europe

Shippers with Europe-bound or intra-Asia freight should lock capacity early and confirm freighter access, while transpacific tech shippers brace for firmer rates and tighter allocations from mid-October onward.
