S.D. Codified Laws § 38-34-10

An assessment at the rate of one percent of the net market price is levied and imposed on any pulse crop grown or sold in South Dakota to a first purchaser. The council may enter into reciprocal agreements with other states that also have a pulse checkoff to remit the assessment to the state where the crop is grown. This assessment is due on any identifiable lot or quantity of a pulse crop.
