If you ordered directly from Mosaic there is no VAT included, they do not use the EU IOSS ("Import One Stop Shop") scheme as far as I know. Within the EU you pay VAT on arrival of an order from outside the EU, unless the non-EU seller uses IOSS, in that case VAT is charged at check-out if the total value does not exceed 150 euros, and no VAT is due on arrival.
By the way - and this might be of interest to EU residents - Belgian store TYQMusic is currently offering the Byas Mosaic for 189 euros (pre-order) plus shipping. They told me they're expecting the set mid- or late December: TYQMusic
