Every person, before commencing business under a trade name as an export warehouse proprietor, shall furnish with his application for permit, required by § 44.82, a true copy of the certificate or other document, if any, issued by a State, county, or municipal authority in connection with the transaction of business under such trade name. If no such certificate or other document is so required a written statement, in duplicate, to that effect by such person will be sufficient for the purpose of this section.
