The Role of Eurostat
Eurostat also produce an annual EU Quality Report. for trade in goods.

The Rotterdam-Antwerp Effect
This effect relates to the distortion pf EU/Non-EU trade figures where goods pass through the large ports of Rotterdam and Antwerp. For instance, if goods arrive in the Dutch port of Rotterdam from outside the EU with the UK being the final destination, they may be recorded as extra-EU imports by the Netherlands. This in turn increases the Intra-EU flow from the Netherlands to the UK when the goods are re-exported. The same situation can occur in reverse where goods are sent from the UK to a country outside the EU via Rotterdam. A similar issue arises to a lesser extent with Antwerp and other ports but Rotterdam is often cited due to the volume and value of trade that passes through this port.
