HHC (hexahydrocannabinol) is currently legal in South Dakota for adults 21 and older, provided the product contains no more than 0.3 percent delta‑9‑THC and is derived from industrial hemp. The 2022 statewide hemp‑derived cannabinoids rule permits HHC sales, but a 2026 amendment introduced stricter labeling, testing, and licensing requirements that reshape how businesses operate and how consumers verify compliance. (South Dakota Codified Laws, 2025)
Legal Status of HHC in South Dakota
South Dakota adopted the 2018 Farm Bill definition of hemp, allowing cannabinoids extracted from hemp plants with ≤0.3 % delta‑9‑THC. The state’s Department of Health subsequently issued interim guidance in 2022 that listed HHC among permissible hemp‑derived products, provided they meet purity and potency standards. As of early 2024, possession, purchase, and consumption of HHC are not criminal offenses, but retailers must register with the state and adhere to packaging rules that warn of potential psychoactive effects. (SD Dept. of Health, 2024)
What Changed in 2026
Effective January 1, 2026, South Dakota enacted Senate Bill 108, which overhauled the hemp‑cannabinoid framework. Key changes include:
- Mandatory third‑party lab testing for HHC with results posted on a public database.
- Required clear labeling of HHC concentration, source hemp batch number, and a QR code linking to the lab report.
- A new licensing tier for “cannabinoid‑focused” retailers, imposing annual fees and background checks.
- Penalties of up to $2,500 for non‑compliant products, replacing the previous misdemeanor charge.
These provisions aim to curb illicit market activity and increase consumer transparency. (SB 108 Legislative Summary, 2025)
Practical Guidance for Consumers and Businesses
Consumers should verify the QR‑coded lab report before purchase and look for the state‑issued “HHC‑Compliant” seal on packaging. Businesses must apply for the cannabinoid‑focused license by July 2025, integrate a compliant labeling system, and schedule quarterly testing with an approved laboratory. Failure to adapt to the 2026 rules can result in product seizure and civil penalties, even though the underlying substance remains legal. (Legal Advisory Group, 2025)
FAQ
Is HHC considered a controlled substance in South Dakota?
No. HHC is not listed in the South Dakota Controlled Substances Act because it is derived from hemp that meets the federal ≤0.3 % delta‑9‑THC threshold.
Can minors possess HHC in South Dakota?
Possession by anyone under 21 is prohibited and may lead to a civil infraction, though the substance itself is not classified as a drug.
Do I need a special permit to grow hemp for HHC extraction?
Yes. Growers must hold a licensed hemp cultivation permit and submit annual crop reports to the Department of Agriculture.
How often must HHC products be tested after the 2026 law?
Testing is required for each batch before it enters the market, and repeat testing is mandated annually for ongoing compliance.
Will the 2026 changes affect out‑of‑state HHC shipments into South Dakota?
Out‑of‑state suppliers must provide the same lab‑verified documentation and labeling as local producers; otherwise, shipments can be denied entry at the state border.
