Items being sold into the EU from England, Scotland and Wales are subject to new VAT rules and can be sold through EU Import One Stop Shop (IOSS):
Any item, regardless of value, sold to the EU is subject to the local rate of VAT and charges in the destination country.
The IOSS scheme allows buyers to pay VAT on items worth up to €150 at the point of purchase. This avoids them having to pay VAT upon delivery.
Signing up to the IOSS isn't mandatory, but the larger marketplaces have registered to it on behalf of all their sellers.
