In order to identify wood carvings, produced entirely by hand, the Bolzano Chamber of Commerce certifies the genuineness of this procedure. This certification is made in two successive stages: a trade-mark, duly registered, is attached to the object, and a certificate is issued declaring that it is entirely and exclusively handcarved. The trade-mark consists of a metal disc bearing the inscription "ENTIRELY HAND CARVED".

The trade mark is attached in a special place on the base of the carving after the latter has been rough-hewn. The application of the trade-mark is done by an expert chosen by the Chamber of Commerce of Bolzano. After the work has been completed and carefully examined, the expert issues the certificate, which is an official document of the Chamber of Commerce, numbered progressively and containing all the information necessary for the unmistakable identification of the wood-carving.
