Maple wood, country of origin and is it treated?

I would like to bring my keyboardio with me to New Zealand. There are quite strict biosecurity checks on entry to the country to avoid bringing in new pests. Does anyone know the country of origin of the maple used in these keyboards and if the wood is treated?

According to this backer update, the wood is Canadian Maple. And this other one explains how the enclosure’s wood is treated.
