The introduction of the new intrastat survey system, following the abolition of intra-EU customs controls, has resulted in some discontinuities in the classification of trade by country of origin/destination. The problem arises in relation to non-EU trade which transits through other member states. Previously some of this trade was incorrectly classified as EU trade, whereas under the new system the classification by origin/destination is more accurate. As a result, the published figures tend to overstate the real increase in trade with non-EU countries, while understating the increase in intra-EU trade.
