S.D. Codified Laws § 36-11A-22

For the purposes of §§ 36-11A-20 to 36-11A-46, inclusive, a manufacturer's exclusive distributor is any person who contracts with a manufacturer to provide or coordinate warehousing, distribution, or other services on behalf of a manufacturer and who takes title to that manufacturer's prescription drug, but who does not have general responsibility to direct the sale or disposition of the manufacturer's prescription drug. Such manufacturer's exclusive distributor must be licensed as a wholesale distributor under §§ 36-11A-20 to 36-11A-46, inclusive, and to be considered part of the normal distribution channel must also be an authorized distributor of record.
