Yes, they will. I remember seeing minis being on the exemption list.
Shipping will rape you though.
My very first airsoft was a Cyma springer, or springers I should say. A smallish handgun (which, in a way, could still "resemble" a real firearm), and a disassembled rifle, which through X-ray. Its size was about 2/3rd's of a real rifle. Got through customs without a hitch, didn't even pay for customs.
