The B2B type of sale is allowed at European level, only if the company that buys is authorized for intra-European trade, as specified by the European Commission and better specified at the following address: http://ec.europa.eu/taxation_customs/business_en.
I declare under my responsibility to be qualified for intra-community trade (*)
The authorization for intra-community trade provides for the non-applicability of VAT and for this reason it is required, under its responsibility, to confirm its registration with the VIES (Vat Information Exchange System). Otherwise Italian VAT of 22% will be applied.
