South Dakota Hemp & Hemp‑Derived Cannabinoid Laws (2026)

This guide outlines South Dakota’s current hemp and hemp‑derived cannabinoid laws as of August 1, 2026, for educational purposes only—not legal advice.

South Dakota hemp laws: quick overview

South Dakota defines “industrial hemp” as Cannabis sativa L. with total Δ9‑THC ≤ 0.3% on a dry‑weight basis (SDCL 38‑35‑1, effective Jan 1 2027) ([sdlegislature.gov](https://sdlegislature.gov/Statutes/38-35?utm_source=openai)). “Industrial hemp product” must also meet that threshold and explicitly excludes chemically derived cannabinoids such as Δ8‑THC, Δ10‑THC, and THC‑O‑acetate (SDCL 38‑35‑1, eff. Jan 1 2027) ([sdlegislature.gov](https://sdlegislature.gov/Statutes/38-35?utm_source=openai)). The sale or use of industrial hemp for smoking or inhaling is prohibited and constitutes a Class 1 misdemeanor (SDCL 38‑35‑21, eff. Mar 27 2020) ([sdlegislature.gov](https://sdlegislature.gov/Statutes/38-35?utm_source=openai)). South Dakota law also prohibits chemical modification of hemp or conversion of CBD into Δ8, Δ9, Δ10, or other THC isomers, and bans sale or distribution of such products—violation is a Class 2 misdemeanor (SDCL 34‑20B‑118, SL 2024, ch 129, § 2) ([sdlegislature.gov](https://sdlegislature.gov/Statutes/34-20B?utm_source=openai)). Additionally, selling or distributing Δ8, THC‑O, HHC, or Δ9‑THCA to persons under 21 is unlawful (Class 2 misdemeanor), with stricter penalties if obtained without prescription (Class 1 misdemeanor) (SDCL 34‑20B‑117, effective July 1 2026) ([sdlegislature.gov](https://sdlegislature.gov/Statutes/34-20B?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp are allowed only if from licensed growers/processors. Transporters must carry proper documentation and are deemed to consent to warrantless inspection; law enforcement may sample up to 8 ounces to test THC compliance (SDCL 38‑35‑16) ([sdlegislature.gov](https://sdlegislature.gov/Statutes/38-35?utm_source=openai)). Retailers must be licensed; unlicensed transport or sale is misdemeanor.

Testing & COA guidance

South Dakota Department of Agriculture requires pre‑harvest inspection and sampling within 30 days before harvest; no lot may leave licensee control until lab confirms compliance (DANR Industrial Hemp Program) ([danr.sd.gov](https://danr.sd.gov/Agriculture/Inspection/IndustrialHemp/default.aspx?utm_source=openai)). Laboratories are not required to be ISO 17025 accredited, though USDA encourages quality assurance protocols (SD State Hemp Plan) ([danr.sd.gov](https://danr.sd.gov/Agriculture/Inspection/IndustrialHemp/docs/SD%20State%20Hemp%20Plan_2021.pdf?utm_source=openai)).

What to buy

Non‑smokable hemp products with total Δ9‑THC ≤ 0.3% dry weight, derived from licensed hemp, excluding chemically derived cannabinoids (i.e., natural CBD, CBG, CBN products compliant with Δ9 limit).

What to avoid

Smokable hemp flower or inhalable hemp products; any products containing Δ8‑THC, Δ10‑THC, THC‑O, HHC, Δ9‑THCA, or other chemically derived cannabinoids; products sold to under‑21 without prescription.
