Any individual, partnership, corporation, association or other business unit which sells hens in Alabama shall, in the event assessments are required to be added to the purchase price of such hens under the provisions of this article, obtain from the Commissioner of Agriculture and Industries a permit which shall authorize such individual or business firm to engage in business in Alabama. The permit shall be valid and effective for an indefinite period unless revoked by the commissioner for failure to comply with the provisions of this article. The application for a permit shall be accompanied by a fee of $10.00 which shall be deposited in the State Treasury to the credit of the Agricultural Fund. The permit shall be conditioned upon compliance with the provisions of this article and rules and regulations duly adopted for carrying out the requirements of this article relative to the remittance of assessments by individuals or business firms selling hens in Alabama, whether such individuals or business firms are domiciled in Alabama or another state. The Board of Agriculture and Industries under Section 2-8-167, is empowered to exempt, by rules and regulations, sellers of hens from the permit requirements of this section when the board determines that insufficient hens are being sold by the seller.
