Keep an Article 6 evidence file that lets product, legal, quality, marketplace operations, logistics, and support teams reconstruct why an offer was or was not EU-targeted. The record should connect the online facts to the responsible operator, conformity documents, import path, and authority-response contacts for the exact product version and units.
The most useful evidence is contemporaneous: live offer screenshots, exportable marketplace settings, EU checkout tests, order confirmations, logistics records, Article 4 contact-label proofs, declarations, technical-documentation access assurances, supplier or manufacturer cooperation commitments, authority correspondence, and corrective-action logs. Reopen the file when territory settings, fulfilment location, seller identity, manufacturer identity, product version, applicable legislation, warning text, or operator contact details change.
