All figures from EU webshops have been calculated on the basis of a method which is still under development and are therefore provisional. The volume of Dutch online consumer purchases from foreign EU webshops is calculated on the basis of VAT declarations. Filing VAT returns in the Netherlands is compulsory for companies selling products to Dutch consumers from other countries, with a threshold amount of 100 thousand euros in annual turnover. It is not compulsory for those companies with an annual turnover in the Netherlands which falls below this amount. These companies fall outside the scope of this survey. With the VAT returns as a source, it is possible to collect data on the foreign webshops visited by Dutch consumers ordering purchases.
