Because of Brexit, which went into effect in 2020 you can no longer ship your UK stored products outside of the UK. The good ol’ days are behind us. So, if you have a Amazon marketplace in the UK which means all of your SKUs are physically stored in a Amazon UK facility. Then, you can only ship your SKUs within the UK. In order to continue shipping your SKUs throughout Europe you will need to open up a Amazon marketplace in either Germany, France, Italy, or Spain.
