Iowa hemp laws: quick overview

Iowa defines hemp under Iowa Code Chapter 204 (Iowa Hemp Act), adopting the federal 0.3% Δ9‑THC dry‑weight limit (Iowa Code §204.2, §204.8) ([rules.iowa.gov](https://rules.iowa.gov/Notice/Details/4842C?utm_source=openai)). In 2024, House File 2605 introduced a stricter framework for intoxicating hemp consumables, including per‑serving and per‑package THC limits, age 21+ requirement, and enforcement by the Alcoholic Beverages Division ([cannabisiowa.org](https://cannabisiowa.org/hemp/overview?utm_source=openai)). Consumable hemp products must contain no more than 0.3% total THC and are regulated by Iowa HHS under Iowa Administrative Code 641‑156 and Iowa Code §204.14A, which prohibits inhalable forms ([hhs.iowa.gov](https://hhs.iowa.gov/health-prevention/consumable-hemp?utm_source=openai)). Transport of hemp requires a certificate of analysis, bill of lading, and license when applicable, per Iowa Code §204A.6, effective December 31, 2024 ([law.justia.com](https://law.justia.com/codes/iowa/title-v/chapter-204a/section-204a-6/?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp are allowed if compliant with Iowa’s Industrial Hemp Act and accompanied by COA and bill of lading; smokable hemp shipments are prohibited under Iowa Code §204.14A ([hempdata.io](https://hempdata.io/states/iowa?utm_source=openai)). Transporters must carry COA, bill of lading, and license if required ([law.justia.com](https://law.justia.com/codes/iowa/title-v/chapter-204a/section-204a-6/?utm_source=openai)).

Testing & COA guidance

Consumable hemp products must be tested by an independent ISO/IEC 17025‑accredited laboratory for Δ9‑THC (≤ 0.3% dry weight), pesticides, solvents, metals, pathogens, and toxicants per Iowa Administrative Code 641‑156. COAs must be maintained and provided on request ([rules.iowa.gov](https://rules.iowa.gov/Notice/Details/5265C?utm_source=openai)).

What to buy

Legal products include non‑inhalable consumable hemp (e.g., gummies, oils, topicals) with ≤ 0.3% total THC, produced in licensed/registered facilities and sold by registered retailers ([hhs.iowa.gov](https://hhs.iowa.gov/health-prevention/consumable-hemp?utm_source=openai)). Raw hemp flower ≤ 0.3% Δ9‑THC is legal for cultivation and processing ([hempdata.io](https://hempdata.io/states/iowa?utm_source=openai)).

What to avoid

Avoid Delta‑8, Delta‑10, HHC, synthetic cannabinoids—these are banned and considered controlled substances ([delta8bans.com](https://delta8bans.com/states/iowa-delta8-legal-status?utm_source=openai)). Inhalable forms (vapes, smokable hemp, pre‑rolls) are prohibited under Iowa Code §204.14A ([hhs.iowa.gov](https://hhs.iowa.gov/health-prevention/consumable-hemp?utm_source=openai)).
