There are no limits on what you can buy and take with
you when you travel between EU countries, as long as the
products purchased are for personal use and not for
resale, with the exception of new means of transport.
Taxes (VAT and excise) are included in the price you pay
and no further payment of tax can be due in any other EU
country.
However, special rules apply in the case of
goods subject to excise duty, such as alcoholic
beverages and tobacco products. To know more on this
issue, see the Commission website on
Taxation and Customs Union.
