Missouri, USA hemp laws: quick overview

Missouri law defines “industrial hemp” as Cannabis sativa L. with a crop‑wide average Δ9‑THC concentration not exceeding 0.3% on a dry weight basis, per RSMo §195.740, effective August 28, 2019 ([revisor.mo.gov](https://revisor.mo.gov/main/OneSection.aspx?bid=47627&section=195.740&utm_source=openai)). Producers must hold a valid producer registration and follow Department of Agriculture rules; failure to comply may result in fines under §195.752 (effective 2019) ([law.justia.com](https://law.justia.com/codes/missouri/2021/title-xii/chapter-195/section-195-752/?utm_source=openai)). Non‑compliant hemp (total THC >0.3%) must be remediated within 60 days under MDA’s remediation protocol (updated March 25, 2021) ([ams.usda.gov](https://www.ams.usda.gov/sites/default/files/media/MissouriHempPlan.pdf?utm_source=openai)). In response to public health concerns, Governor Kehoe signed HB 2641 on April 23, 2026, establishing a per‑serving THC cap of 0.4 mg for intoxicating hemp products, restricting their sale to state‑licensed marijuana dispensaries, requiring purchasers to be 21+, and imposing 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)). Additionally, Executive Order 24‑10 (August 1, 2024) prohibits the sale, production, and distribution of synthetic cannabinoids—including Δ8 and Δ10 THC—classifying them as controlled substances under state law ([atach.org](https://atach.org/cannabis-and-hemp-encyclopedia/missouri/missouri-hemp-intoxicants-regulations/?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products meeting ≤0.3% Δ9‑THC are allowed under the state hemp program. Shipping intoxicating hemp products (those exceeding 0.4 mg THC per serving) is prohibited unless shipped to state‑licensed marijuana dispensaries. Age verification (21+) is required for intoxicating hemp under HB 2641. Retailer registration via MDA is required for producers; intoxicating hemp must be sold only through licensed dispensaries.

Testing & COA guidance

Missouri requires testing for Δ9‑THC and total THC (post‑decarboxylation) per MDA rules; producers must submit COAs within 7 calendar days of non‑compliance ([agriculture.mo.gov](https://agriculture.mo.gov/plants/industrial-hemp/faq.php?utm_source=openai)). Remediation testing must follow MDA’s protocol ([ams.usda.gov](https://www.ams.usda.gov/sites/default/files/media/MissouriHempPlan.pdf?utm_source=openai)). ISO/IEC 17025 accreditation is implied by “state‑approved labs” but not explicitly stated in available sources—status unknown.

What to buy

Products derived from hemp with ≤0.3% Δ9‑THC dry weight are legal. Non‑intoxicating hemp products (e.g., CBD oils, topicals, fiber, grain) remain legal. Intoxicating hemp products with ≤0.4 mg THC per serving may be purchased only at state‑licensed marijuana dispensaries by individuals 21+.

What to avoid

Avoid synthetic cannabinoids including Δ8, Δ10, HHC, THC‑O—banned under Executive Order 24‑10. Avoid intoxicating hemp products exceeding 0.4 mg THC per serving. THCa flower that converts to Δ9‑THC above 0.3% may be subject to enforcement under MMPA ([missourihemphoax.com](https://missourihemphoax.com/laws?utm_source=openai)).
