I think it would need to be a private arrangement as Fitch are the only sellers (Amazon sell it but it still goes via Fitch directly).
There are similar beddings sold by rat rations who ship all over the world I believe- not sure how much it costs. You’d have to put something in the basket and go partway through checkout to find how much shipping would be. They sell aubiose (hemp), pure comfort (paper) and finacard and other soft card bedding.
I’ve used Pure Comfort before - it’s ok but can have a tiny bit of dust. Not as good as Fitch but similar. You could mix a paper substrate with Finacard to make it go further abd have another texture.
However with the current pandemic situation and flight restrictions it could be difficult to get anything shipped abroad.
