The official airport list places cultural heritage appraisal counters near T1 Level 3 check-in counter H (032-740-2921/2922) and near the central government service complex on T2 Level 2 (032-743-2923/2924). Travelers carrying old artworks or potentially protected heritage abroad may be subject to export rules, so check with the competent authority. The existence of these counters does not establish that a particular object may legally leave Korea. Ask about required documents, advance declarations and hours.
