Missouri, USA hemp laws: quick overview

Missouri law defines “industrial hemp” as Cannabis sativa L. and its derivatives containing no more than 0.3% Δ9‑THC on a dry‑weight basis, per Mo. Rev. Stat. § 261.255 et seq., enacted via SB 599 (2018) and amended through 2023; this aligns with the federal 2018 Farm Bill standard ([hempdata.io](https://hempdata.io/states/missouri?utm_source=openai)). The Missouri Department of Agriculture oversees hemp cultivation and requires producer registration and propagule/seed permits under the Industrial Hemp Program (Sections 195.010–195.773 RSMo) ([agriculture.mo.gov](https://agriculture.mo.gov/plants/industrial-hemp/faq.php?utm_source=openai)). Missouri requires testing for compliance using Total THC measured post‑decarboxylation (Δ9‑THC + THC‑A × 0.877) with a margin of uncertainty; compliant samples must be ≤ 0.3% Total THC ([agriculture.mo.gov](https://agriculture.mo.gov/plants/industrial-hemp/faq.php?utm_source=openai)). In April 2026, HB 5739 was signed to ban intoxicating hemp products (e.g., Δ9 edibles, beverages) effective November 12, 2026; after that date, such products must be sold only through licensed marijuana dispensaries under Amendment 3’s cannabis framework ([tryfloral.com](https://tryfloral.com/pages/thc-laws-missouri?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products meeting the ≤ 0.3% Δ9‑THC threshold are allowed under the hemp program. No special age verification or retailer registration is required for non‑intoxicating hemp products. After November 12, 2026, intoxicating hemp products must be sold via licensed marijuana dispensaries, so shipping into general retail or direct‑to‑consumer channels will be prohibited for those products.

Testing & COA guidance

Missouri requires testing by independent laboratories using post‑decarboxylation methods (e.g., GC or HPLC) to measure Total THC (Δ9 + THC‑A × 0.877) and include a margin of uncertainty; Certificate of Analysis must accompany retail hemp products ([agriculture.mo.gov](https://agriculture.mo.gov/plants/industrial-hemp/faq.php?utm_source=openai)). Labs must be independent (no ownership overlap with hemp businesses) per 2 CSR 70‑17 rules ([agriculture.mo.gov](https://agriculture.mo.gov/plants/industrial-hemp/industrial-hemp-proposed-rules.pdf?utm_source=openai)).

What to buy

Non‑intoxicating hemp products (e.g., CBD, Δ9 ≤ 0.3% dry weight) remain legal and available through hemp‑registered channels. Until November 12, 2026, hemp‑derived Δ9 beverages, edibles, and similar products are permitted if compliant. After that date, only licensed marijuana dispensaries may sell intoxicating hemp products.

What to avoid

Avoid hemp products exceeding 0.3% Total THC (Δ9 + THC‑A × 0.877) in the hemp channel. After November 12, 2026, avoid purchasing intoxicating hemp products (e.g., Δ9 edibles, beverages) from non‑dispensary retailers. Synthetic cannabinoids or lab‑derived intoxicants may be subject to additional restrictions and are not clearly addressed in state law.
