Does wood warp when shipped to the mainland?

[7Shadows]

I make and sell a variety of wooden plaques online and was wondering if anyone has shipped any flat Hawaiian wooden items to drier climates and had them warp.

I'm just not sure if the warping occurs during the first time the lumber was dried, or does it have the possibility to warp again after sitting in the humid air (soaking up moisture again) and then drying out in less humid climate.

Thanks to anyone that has some info on this subject.
