Before any license is issued the applicant shall make and deliver to the Commissioner a surety bond executed by a surety corporation authorized to transact business in this state and approved by the Commissioner. Any and all bond applications shall be accompanied by a certificate of "good standing" issued by the Commissioner of Insurance. If any company issuing a bond shall be removed from doing business in this state, it shall be the duty of the Commissioner of Insurance to notify the Commissioner of Agriculture within 30 days. The bond shall be in such amount as the Commissioner may determine, not exceeding an amount equal to the maximum amount of products purchased from or sold for Georgia producers or estimated to be purchased or sold in any month by the applicant or in the case of cotton not to exceed $150,000.00. Such bond shall be upon a form prescribed or approved by the Commissioner and shall be conditioned to secure the faithful accounting for and payment to producers or their agents or representatives of the proceeds of all agricultural products handled or sold by such dealer. However, in lieu of a surety bond, the Commissioner may accept a cash bond, which shall in all respects be subject to the same claims and actions as would exist against a surety bond. Whenever the Commissioner shall determine that a previously approved bond has for any cause become insufficient, the Commissioner may require an additional bond or bonds to be given, conforming with the requirements of this Code section. Unless the additional bond or bonds are given within the time fixed by written demand therefor, or if the bond of a dealer is canceled, the license of such person shall be immediately revoked by operation of law without notice or hearing.
