Invoices covering works of art claimed to be free of duty under subheadings 9702.00.00 and 9703.00.00, HTSUS, shall show whether they are originals, replicas, reproductions, or copies, and also the name of the artist who produced them, unless upon examination the Customs officer is satisfied that such statement is not necessary to a proper determination of the facts.

The following evidence shall be filed in connection with the entry: A declaration, or its electronic equivalent, in the following form by the artist who produced the article, or by the seller, shipper or importer, showing whether it is original, or in the case of sculpture, the original work or model, or one of the first twelve castings, replicas, or reproductions made from the original work or model; and in the case of etchings, engravings, woodcuts, lithographs, or prints made by other hand-transfer processes, that they were printed by hand from hand-etched, hand-drawn, or hand-engraved plates, stones, or blocks:

I, ____, do hereby declare that I am the producer, seller, shipper or importer of certain works of art, namely ____ covered by the annexed invoice dated ____; that any sculptures or statuary included in that invoice are the original works or models or one of the first twelve castings, replicas, or reproductions made from the sculptor's original work or model; and that any etchings, engravings, woodcuts, lithographs, or prints made by other hand-transfer processes included in that invoice were printed by hand from hand-etched, hand-drawn, or hand-engraved plates, stones, or blocks.

The Center director may waive the declaration requirement set forth in paragraph (b) of this section.

Artists' proof etchings, engravings, woodcuts, lithographs, or prints made by other hand-transfer processes should bear the genuine signature or mark of the artist as evidence of their authenticity. In the absence of such a signature or mark, other evidence shall be required which will establish the authenticity of the work to the satisfaction of the Center director.
