I have no idea about import or export taxes.
Not exactly this stile, but there are a lot of makers who offer Loden jackets in modern design, let's say a more adult design that doesn't get out of fashion.
Things, that you also could buy in tweed.
I own for example from Rascher a tweed jacket and a Loden jacket and both are similar in stile. I got both very cheap, but regular they are everything else than cheap.
The hunting shops are full of it, as Loden is very silent in use. I think there are also cheaper brands, but as I bought new Loden jackets in trhift shops for 60 € that cost regularly 600 € I didn't pay so much attention about cheaper regular Loden jackets.
But I think, the fabric itself is relatively expensive.
