Kentucky, USA hemp laws: quick overview

Kentucky law defines hemp as Cannabis sativa L. with delta‑9 THC not exceeding 0.3% on a dry‑weight basis, aligning with federal law (KRS § 260.858, amended 2020, effective February 10 2020) ([law.justia.com](https://law.justia.com/codes/kentucky/chapter-260/section-260-858/?utm_source=openai)). The Kentucky Department of Agriculture applies an “Acceptable Hemp THC Level,” which adds the statewide measurement of uncertainty to the 0.300% limit when evaluating compliance (302 KAR 50:056) ([apps.legislature.ky.gov](https://apps.legislature.ky.gov/law/kar/titles/302/050/056/3361/?utm_source=openai)). In March 2023, House Bill 544 established a regulatory framework for hemp‑derived intoxicating cannabinoids, including delta‑8 THC, requiring adult‑use cannabinoid products to be registered, labeled, and sold only to those 21 and older; this framework took effect in August 2023 (HB 544, Chapter 78) ([allowedhere.com](https://allowedhere.com/legality/delta-8-thc/kentucky/?utm_source=openai)). Administrative regulation 902 KAR 45:190 lists specific cannabinoids (e.g., delta‑8, delta‑10, THCA‑A ≤ 0.3% total THC, HHC, etc.) that are permitted under registration, and prohibits all others unless pre‑approved by the cabinet ([law.cornell.edu](https://www.law.cornell.edu/regulations/kentucky/902-KAR-45-190?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp and hemp‑derived cannabinoid products are allowed only if the sender and recipient are licensed or registered with the Kentucky Department of Agriculture or relevant cabinet. Adult‑use cannabinoid products must verify recipient is 21+. Retailer or manufacturer registration is required under 902 KAR 45:190.

Testing & COA guidance

Kentucky requires lab testing for THC content: delta‑9 THC must be below the Acceptable Hemp THC Level (0.300% + uncertainty) per 302 KAR 50:056. Licensed growers must test pre‑harvest and may retest or destroy non‑compliant lots. COAs must reflect measurement uncertainty. ISO/IEC 17025 accreditation is implied by KDA lab standards but not explicitly stated in available sources.

What to buy

State‑legal products include hemp flower, extracts, and adult‑use cannabinoid products (e.g., delta‑8, delta‑10, THCA‑A ≤ 0.3% total THC, HHC, THCV, THCp, THCM) that are registered, labeled with cannabinoid names, and comply with THC limits and age restrictions.

What to avoid

Avoid any hemp‑derived products exceeding 0.3% delta‑9 THC (dry weight), unregistered intoxicating cannabinoid products, and cannabinoids not listed in 902 KAR 45:190 unless pre‑approved. Synthetic or unapproved cannabinoids remain prohibited.

How to shop compliant, tested hemp

• Delta‑9 THC in hemp must not exceed 0.3% dry weight (KRS § 260.858, effective Feb 10 2020)
• Kentucky uses an “Acceptable Hemp THC Level” = 0.300% + measurement of uncertainty (302 KAR 50:056)
• Delta‑8 and other intoxicating cannabinoids require product registration under 902 KAR 45:190
• Must be 21+ to purchase adult‑use hemp‑derived cannabinoid products (HB 544 framework)
