Kentucky, USA hemp laws: quick overview

Kentucky law aligns with the federal 0.3% Δ9‑THC dry‑weight limit but applies it to total THC post‑decarboxylation in finished products. Under 302 KAR 50:070, hemp products with Δ9‑THC over 0.3% or smokable flower are prohibited (effective as of June 1 2025) ([regulations.justia.com](https://regulations.justia.com/states/kentucky/title-302/chapter-50/070/?utm_source=openai)). House Bill 544 (2023), effective January 1 2024, directed CHFS to regulate hemp‑derived intoxicating cannabinoid products, requiring product registration, age limits (21+), and testing/labeling rules under 902 KAR 45:190 ([cannabisregulations.ai](https://www.cannabisregulations.ai/state-legality/kentucky-delta-9?utm_source=openai)). The Department of Agriculture statutes (KRS § 260.858) make it unlawful for unlicensed persons to handle hemp materials or extracts over 0.3% Δ9‑THC (dry‑weight) ([codes.findlaw.com](https://codes.findlaw.com/ky/title-xxi-agriculture-and-animals/ky-rev-st-sect-260-858/?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp‑derived cannabinoid products into Kentucky are allowed only if the SKU is registered on the CHFS Approved Product Registry and meets labeling/testing requirements. Age verification (21+) is required at retail. Retailers must be registered; out‑of‑state manufacturers must register annually and pay $200 per product (902 KAR 45:190) ([apps.legislature.ky.gov](https://apps.legislature.ky.gov/law/kar/titles/902/045/190/?utm_source=openai)).

Testing & COA guidance

Kentucky requires ISO‑style testing per 902 KAR 45:190: testing facilities must have LOQ ≤ 1 mg/g, report total THC (post‑decarboxylation), THCA, mg per serving, mg per package, and all cannabinoids as % and mg/g on COA ([law.cornell.edu](https://www.law.cornell.edu/regulations/kentucky/902-KAR-45-190?utm_source=openai)). COAs must accompany products; retention rules not specified in available sources.

What to buy

Legal products include registered hemp‑derived cannabinoid edibles, beverages, tinctures, vapes, concentrates, and topicals that comply with total THC ≤ 0.3% dry‑weight and are on the CHFS registry.

What to avoid

Avoid smokable hemp flower (whole buds, ground floral or leaf material) — these are banned under 302 KAR 50:070. Any product exceeding 0.3% total THC is prohibited. Other cannabinoids (e.g., delta‑8, delta‑10, HHC, THCP, THCM) are prohibited unless pre‑approved by the cabinet under 902 KAR 45:190 ([regulations.justia.com](https://regulations.justia.com/states/kentucky/title-302/chapter-50/070/?utm_source=openai)).
