While the NIA Code of Ethics requires Imitation and Altered Insulators to be plainly marked “reproduction” and “fake” respectively, it does not require Questionable Insulators (those which may not be Original Insulators), to be permanently marked. The goal of this rule is to cause a prospective purchaser to easily recognize that an item is a reproduction or fake, or to cause them to question its authenticity. Insulators of questionable authenticity should be represented with candor. If not, a show host can require a participant to remove the item from a display or sales table. The decision of the show host shall be final. NIA Board Members attending an NIA sanctioned show will provide active assistance, if requested by a show host, in resolving violations of the NIA Rules.
