This circular establishes the electronic validation of the IOSS VAT identification number at the Import Office, for the release into free circulation of low-value shipments (up to 150 euros) that are the subject of distance sales and for which it is not possible to use the oversimplified H7 declaration . At the same time, the other parameters for the importation of said consignments are adjusted using a special VAT return regime through the submission of Import EDE.
