No person, real or corporate, shall operate a service for receiving within this state flue-cured leaf tobacco for the purpose of weighing, redrying, and storing said tobacco from the year of production until the subsequent selling season for sale at that time without first having obtained a license from the Commissioner of Agriculture. Each license so issued shall automatically expire at the termination of the storage period and be subject to renewal annually under such rules and regulations as the Commissioner shall prescribe. The license fee shall be $10.00 for each year. Licensed operators of flue-cured leaf tobacco auction warehouses may be licensed without cost under this part upon application to the Commissioner. This part shall not require licensing of any federal agency, its agents, or contractors who receive carry-over tobacco.
