Good observation. I requested an update from the shipping manager.
Update: Our shipping manager is pushing hard on this. We’ve already obtained approval but there are apparently some communication issues between the DHL representative and DHL tech support. We still await action from DHL tech support.
We are fully approved for international shipping of standalone batteries!
The carrier is charging a significant fee for shipment of dangerous goods - much more than anticipated. We are now working to update the shop to account for these additional charges if a standalone battery is purchased, necessitating the “dangerous goods” label.
Additional data point: A standalone Librem 14 battery shipped to Zurich, Switzerland, would cost $264.39 USD. Ouch.
That looks like a DHL get-lost fee. They want to say they offer it, but don’t want to do it. There are professional carries phone numbers, and if they don’t use L5, the numbers are in the book as they say.
Two things I see Purism being responsible for:
Adding a caveat in the ad about additional batteries.
done. 
Yea!
With great haste, contact professional carries like:
FedEx
United States Postal Services
With the sudden and shocking events I think it is going to, if it hasn’t already, make it much more difficult and expensive to find a backup battery.

The “dangerous goods”, “fuel surcharge”, “transportation charges” fees are insane. I recently bought a 1382 Wh LiFePO4 40lb “Electric Solar Generator” (battery+inverter+charge controller+USB-pd-out + AC in/out that can output 1800W) for $400 delivered (international shipment).
