Unfortunately, the ability to buy goods as a company is not implemented (yet) on our e-shop, therefore it is not possible to buy Trezor products on the Trezor e-shop without paying VAT.
This is something we're looking to implement, and aim to make it available in the future.
We suggest you buy Trezor products from our official Amazon store or from one of our official resellers in case you want to purchase goods without VAT. For reference, you can read this article.
