Guys, last month I bought a Onewheel (https://onewheel.com/) and it got through customs no hassle, just need to pay tax when I received it from Fedex.

Last week my friend ordered another one, and now its stuck at customs and they say need to apply AP Permit. I'm confused, I thought permit only applies to motorized vehicles? This is a battery powered vehicle. Any advice on how to proceed on this?
