Kentucky, USA hemp laws: quick overview

Kentucky law aligns with the 2018 Farm Bill’s 0.3% Δ9‑THC dry‑weight limit, defining hemp accordingly and enforcing it via 302 KAR 50:056 (sampling/testing; effective current) and KRS 260.858(3) (possession limit) ([apps.legislature.ky.gov](https://apps.legislature.ky.gov/Law/kar/titles/302/050/056/?utm_source=openai)). The “Acceptable Hemp THC Level” includes the 0.3% Δ9‑THC plus measurement of uncertainty ([apps.legislature.ky.gov](https://apps.legislature.ky.gov/Law/kar/titles/302/050/056/?utm_source=openai)). Adult‑use hemp‑derived cannabinoid products (including Δ8, Δ10, HHC, THCA‑A ≤0.3% total THC, THCV, THCVA, Δ6, THCp, THCM) must be registered with the Cabinet for Health and Family Services and pay a $200 annual fee per product under 902 KAR 45:190, effective January 1, 2024 ([apps.legislature.ky.gov](https://apps.legislature.ky.gov/law/kar/titles/902/045/190/?utm_source=openai)). Retailers must hold a permit and register products under emergency regulation 902 KAR 45:012; sales to persons under 21 are prohibited, and age verification and secure storage are required ([chfs.ky.gov](https://www.chfs.ky.gov/agencies/dph/dphps/fsb/Pages/HDCP.aspx?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp extracts with THC >0.3% are only allowed between licensed Kentucky processors with 24‑hour advance notice to the Kentucky Department of Agriculture under KRS 260.8635; interstate transport of such material remains unlawful ([kyagr.com](https://www.kyagr.com/marketing/documents/HEMP_LH_Processor_Concentrate_Transport_Form.pdf?utm_source=openai)). Retail shipments inbound to consumers are not specifically addressed; assume standard hemp (<0.3% Δ9) shipments are allowed under federal law, but adult‑use cannabinoid products require retailer permit and product registration.

Testing & COA guidance

Per 902 KAR 45:031 and 45:190, every batch/process lot must be tested by an independent ISO 17025‑accredited lab for cannabinoids (including Δ9, total THC), microbial impurities, mycotoxins, residual pesticides, heavy metals, and residual solvents if applicable ([apps.legislature.ky.gov](https://apps.legislature.ky.gov/law/kar/titles/902/045/190/?utm_source=openai)). Labs must report COAs including total THC %, THCA, mg per serving and per package, and retain reserve samples for two years or shelf‑life ([chfs.ky.gov](https://www.chfs.ky.gov/agencies/dph/dphps/fsb/Pages/HDCP.aspx?utm_source=openai)). Limit of quantitation must be ≤1 mg/g ([apps.legislature.ky.gov](https://apps.legislature.ky.gov/law/kar/titles/902/045/190/?utm_source=openai)).

What to buy

Products compliant with Kentucky law include hemp‑derived cannabinoid products with Δ9‑THC ≤0.3% total THC, including Δ8, Δ10, THCA‑A (≤0.3% total THC), THCV, THCVA, Δ6, HHC, THCp, THCM, provided they are registered and sold by permitted retailers to adults 21+.

What to avoid

Avoid smokable hemp products: hemp cigarettes, cigars, chew, dip, teas, whole buds, ground floral or leaf material are prohibited under 302 KAR 50:070 ([law.cornell.edu](https://www.law.cornell.edu/regulations/kentucky/302-KAR-50-070?utm_source=openai)). Also avoid unregistered adult‑use cannabinoid products or those exceeding 0.3% Δ9‑THC.
