S.D. Codified Laws § 41-6-25
It is a Class 1 misdemeanor for a person to purchase or contract to purchase for a commercial purpose the raw skins of fur-bearing animals or unskinned fur-bearing animals, including jackrabbits, without a fur dealer's license or in violation of the license or the rules of the Game, Fish and Parks Commission. For purposes of this section, commercial purpose is the purchase of or contract to purchase the property by persons who hold themselves out as engaging in the business of purchasing such property and does not include the isolated or occasional purchase of such property.
A fur dealer's license permits the licensee to purchase or contract to purchase the skins of fur-bearing animals, including jackrabbits, for the purpose of resale or other commercial purpose, to the extent and in the manner provided by §§ 41-14-22 and 41-14-23. A fur dealer's license is valid for a period of one year from July first to June thirtieth.
Any person convicted of issuing an insufficient funds check or no account check shall be denied a fur dealer's license until such time as all such checks are paid.
