Montana Hemp & Hemp‑Derived Cannabinoid Laws (2026)

This guide provides educational, state‑specific information on Montana’s hemp and hemp‑derived cannabinoid laws as of August 1, 2026. It is for educational purposes only and does not constitute legal advice.

Montana hemp laws: quick overview

Montana law defines “hemp” as Cannabis sativa L. and any part thereof with a total delta‑9 THC concentration not exceeding 0.3% on a dry‑weight basis (MCA 80‑18‑101, effective 2023) ([mca.legmt.gov](https://mca.legmt.gov/bills/mca/title_0800/chapter_0180/part_0010/section_0010/0800-0180-0010-0010.html?utm_source=openai)). In 2025, SB 375 (codified at MCA 50‑31‑239) prohibited the sale of any hemp product containing total delta‑9 THC to consumers unless authorized by the FDA; this took effect immediately upon passage in 2025 ([mca.legmt.gov](https://mca.legmt.gov/bills/mca/title_0500/chapter_0310/part_0020/section_0390/0500-0310-0020-0390.html?utm_source=openai)). Montana also classifies delta‑8 THC and other synthetic cannabinoids as Schedule I substances under MCA 50‑32‑222, and HB 948 (2023) further bans manufacture, processing, sale, and storage of synthetic cannabinoid products, effective May 22, 2023 ([legalclarity.org](https://legalclarity.org/is-delta-8-legal-in-montana-a-guide-to-state-law/?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products containing any delta‑9 THC are prohibited unless FDA‑authorized. Synthetic cannabinoids (e.g., delta‑8) are banned entirely—shipping such products into Montana is illegal. No specific age‑verification or retailer registration for hemp is detailed beyond licensing for processors and growers.

Testing & COA guidance

Montana requires licensed hemp products to undergo laboratory testing under the state hemp certification program (MCA 80‑11‑1101) ([mca.legmt.gov](https://mca.legmt.gov/bills/mca/title_0800/chapter_0110/part_0110/section_0010/0800-0110-0110-0010.html?utm_source=openai)). The Department of Agriculture may inspect and sample all hemp lots; self‑sampling by growers is allowed for trend‑tracking but not official (ARM 4.19.110) ([regulations.justia.com](https://regulations.justia.com/states/montana/department-4/chapter-4-19/subchapter-4-19-1/rule-4-19-110/?utm_source=openai)). Processors are subject to THC and pesticide testing (ARM 4.19.201) ([agr.mt.gov](https://agr.mt.gov/_docs/industrialhemp-docs/Hemp-MCA-ARM-Booklet.pdf?utm_source=openai)). Testing labs must meet ISO/IEC 17025:2017 accreditation and employ a qualified scientific director per ARM 42.39.602 ([regulations.justia.com](https://regulations.justia.com/states/montana/department-42/chapter-42-39/subchapter-42-39-6/rule-42-39-602/?utm_source=openai)).

What to buy

Non‑intoxicating hemp products with Δ9‑THC ≤ 0.3% dry weight that are not intended for consumption of THC (e.g., fiber, seed, CBD extracts without THC) and are FDA‑authorized if containing THC.

What to avoid

Any hemp product containing delta‑9 THC intended for consumer sale (unless FDA‑authorized), synthetic cannabinoids including delta‑8 THC, smokable THC hemp products, and any unlicensed hemp floral/root extracts without proper processing license.

How to shop compliant, tested hemp
