Missouri, USA hemp laws: quick overview

Missouri law defines “hemp” as Cannabis sativa L. with total THC (including THCA) not exceeding 0.3% on a dry‑weight basis, per RSMo §195.900, effective November 12 2026 under the Intoxicating Cannabinoid Control Act (HB 2641) ([revisor.mo.gov](https://revisor.mo.gov/main/OneSection.aspx?bid=59932&section=195.900&utm_source=openai)). HB 2641, signed April 23 2026, also caps intoxicating hemp‑derived products at 0.4 mg THC per serving, restricts their sale to licensed marijuana dispensaries, and imposes marijuana‑style testing, packaging, and labeling rules ([missourinet.com](https://www.missourinet.com/2026/04/23/missouri-gov-kehoe-signs-4-bills-into-law-including-ban-on-intoxicating-hemp-products/?utm_source=openai)). Separately, SB 518 (effective August 28 2025) establishes the Missouri Hemp Consumer Protection Act, requiring licenses for manufacture, distribution, and retail of hemp‑derived consumables, age‑21 minimum, product registration, testing for contaminants, and labeling with cannabinoid amounts over 1 mg and measurable THC in mg ([senate.mo.gov](https://www.senate.mo.gov/BillTracking/Bills/BillInformation?billid=860121&year=2025&utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products must comply with Missouri’s hemp definition (≤ 0.3% total THC) and licensing requirements. Hemp consumables require license from Division of Alcohol & Tobacco Control; age verification (21+) is mandatory. Intoxicating hemp products (post‑Nov 12 2026) must be handled only by licensed marijuana dispensaries.

Testing & COA guidance

Missouri requires ISO 17025‑accredited labs for hemp testing under the State Plan, including potency (delta‑9 THC) and contaminants (heavy metals, pesticides, mycotoxins, solvents, microbials) ([agriculture.mo.gov](https://agriculture.mo.gov/news/newsitem/uuid/82fc52ff-24fc-4605-a9d8-81eb1ae6f4aa/missouri-industrial-hemp-amendments-approved?utm_source=openai)). Certificates of analysis must accompany products; manufacturers and distributors must ensure testing before distribution. COA retention rules follow DATC guidelines under SB 518.

What to buy

Products meeting hemp definition (≤ 0.3% total THC) and licensed under SB 518: consumables (edibles, beverages, inhalables) with proper labeling and testing. Non‑intoxicating hemp products (e.g., CBD topicals, oils) under MDA registration are allowed.

What to avoid

Avoid intoxicating hemp‑derived cannabinoid products exceeding 0.4 mg THC per serving or sold outside licensed marijuana dispensaries (HB 2641). Smokable hemp flower or THCA flower marketed for psychoactive effects will be regulated as marijuana post‑Nov 12 2026 (RSMo §195.900).
