Owing to the large traffic of unaccounted goods across Andorra's borders, official statistics do not reflect the true volume of transactions. Of recorded trade, close to half is with Spain and over one-quarter with France. The majority of imports consist of consumer goods sold to visitors. Reported imports exceed recorded exports by more than 22:1.
A customs union with the EC (now the EU) took effect in 1991, allowing industrial goods to pass between Andorra and EC members under a uniform customs tariff. The EU's external tariffs are to be applied by Andorra to its trade with non-EU members.
