You still pay taxes in Switzerland, but they're quiet lower. Plus customs often charge a small fee for just "checking" the parcel. I don't think you can get those taxes refunded if you send the parcel back outside the country (as a private person). I'd have to look that up or maybe someone knows it. Switzerland is extremely strict with Lithium batteries (you have NO chance to send it via postal service and their international partners, as the ministry doesn't allow it. Exception: If the battery is in the device). It might be possible though with FedEx and co. as I was told. Unfortunately I also don't know about a mail forwarding company around here.
