It does not constitute legal, tax, or accounting advice, nor does it act as a tax guarantor. Under Article 138 of Council Directive 2006/112/EC, the merchant remains solely responsible for verifying substantive intra-Community exemption conditions (including valid buyer VAT registration via VIES
requestIdentifier and proof of cross-border physical transport pursuant to Implementing Regulation (EU) No 282/2011 Art. 45a). During national VIES member state outages (MS_UNAVAILABLE / MS_MAX_CONCURRENT_REQ), the system defaults to fail-safe VAT-inclusive collection with automated post-verification partial VAT refund or fulfillment hold. Manual override of fail-safe protections places full liability for any assessed VAT, interest, or administrative penalties solely on the merchant.
