External trade in goods statistics is compiled by Eurostat on a monthly basis following a harmonised methodology set out in European regulations (known as the Community concept; and using data collection systems based on both extra-EU and intra-EU (Intrastat) data. According to these regulations, Member States should supply detailed extra-EU trade data to Eurostat six weeks after, aggregated intra-EU data eight weeks after and detailed intra-EU data ten weeks after the end of the reporting month. Eurostat publishes total extra-euro area trade results 50-55 days after the end of the reporting month, while detailed results, broken down by partner and product, become available one month later. It should be noted that extra-euro area results are not as timely as extra-EU data, because the data for the three (four before 2001) EU Member States not participating in the Economic and Monetary Union (namely Denmark, Sweden and the United Kingdom) become available later. An advanced release calendar for Press releases on External Trade can be found on the Eurostat-website (Euro-indicators). The ECB databank includes series upon agreement with ECB data users. Data required for ad hoc purposes can be downloaded from Comext by the users.
