S.D. Codified Laws § 49-45-1
Before transacting the business of a grain buyer in this state, a person shall obtain a grain buyer license from the commission.
A violation of this section is a Class 5 felony if the person holds himself or herself out to be a grain broker and a Class 1 misdemeanor in all other cases. Each purchase of grain without a license is a separate offense.
A grain buyer transacting business without a license may be enjoined upon complaint of the commission.
The commission may assess a civil fine against an unlicensed grain buyer in the amount of five thousand dollars for each purchase of grain, up to a maximum fine of fifty thousand dollars per licensing period, as set forth in § 49-45-3.
For purposes of this section, the term, purchase of grain, means a transaction evidenced by the issuance of a uniform scale ticket or receipt, as described in § 49-45-10.1.
