The “Free Flow of Works by Living Artists” customs certificate of the International Association of Art (IAA) refers to the UNESCO Florence Agreement, adopted in 1950 and expanded to include audiovisual materials in 1982, and pertains to the free transport of works of art by living artists in the signatory countries. It can be understood as a recommendation and may be useful as an accompanying document upon import. The Internationale Gesellschaft der Bildenden Künste (IGBK) provides it to German-based visual artists free of charge. A simplified customs procedure is also in place for the temporary use of works of art in exhibitions (see ATA Carnet).
