Iowa Hemp & Hemp‑Derived Cannabinoid Laws

This guide provides educational, state‑specific information on Iowa’s hemp and hemp‑derived cannabinoid laws. It is for informational purposes only and does not constitute legal advice.

Iowa hemp laws: quick overview

Iowa’s hemp law is grounded in the Iowa Hemp Act (Iowa Code Chapter 204), which defines hemp as cannabis with Delta‑9 THC not exceeding 0.3% on a dry‑weight basis, aligning with federal law ([legalclarity.org](https://legalclarity.org/is-delta-9-legal-in-iowa-iowas-hemp-laws/?utm_source=openai)). The Act’s definitions (§204A.2) reference federal definitions and total THC as per 7 C.F.R. §990.1 ([legis.iowa.gov](https://www.legis.iowa.gov/docs/code/204A.2.pdf?utm_source=openai)). In 2024, House File 2605 took effect on July 1, 2024, imposing stricter limits on consumable hemp: maximum 4 mg total THC per serving and 10 mg per package; it also bans synthetic and semi‑synthetic cannabinoids and flower/raw bud products ([legalclarity.org](https://legalclarity.org/is-delta-9-legal-in-iowa-iowas-hemp-laws/?utm_source=openai)). Iowa HHS rules further prohibit inhalable consumable hemp (vapes, pre‑rolls, etc.) under Iowa Code 204.14A and require consumable hemp to contain ≤ 0.3% total THC dry weight ([hhs.iowa.gov](https://hhs.iowa.gov/health-prevention/consumable-hemp?utm_source=openai)).

Shipping guidance

Inbound shipments of consumable hemp products are allowed if they comply with Iowa’s limits (≤ 0.3% total THC dry weight, ≤ 4 mg per serving, ≤ 10 mg per package), and are registered with Iowa HHS. Age verification (21+) is required at point of sale. Retailers must register as consumable hemp establishments with Iowa HHS; unregistered shipments risk seizure or enforcement.

Testing & COA guidance

Iowa requires testing by approved labs following Iowa Administrative Code Chapter 96 and Iowa Code Chapter 204. Testing must measure Delta‑9 THC post‑decarboxylation (total potential Delta‑9) and ensure ≤ 0.3% dry weight ([legis.iowa.gov](https://www.legis.iowa.gov/docs/code/2022/204.pdf?utm_source=openai)). Certificates of Analysis must accompany products. ISO/IEC 17025 accreditation is implied by state lab approval but not explicitly stated in sources; COA retention requirements are not specified in available sources (set to null).

What to buy

Legal products include consumable hemp edibles, beverages, tinctures, topicals, and other ingestible forms that meet: ≤ 0.3% total THC dry weight, ≤ 4 mg THC per serving, ≤ 10 mg per package, and are non‑inhalable and registered with Iowa HHS.

What to avoid

Avoid Delta‑8, Delta‑10, HHC, synthetic/semi‑synthetic cannabinoids—they are banned under HF 2605. Also avoid smokable hemp flower or raw bud, inhalable products (vapes, pre‑rolls), products exceeding THC limits, and unregistered consumables ([hhs.iowa.gov](https://hhs.iowa.gov/media/15551/download?utm_source=openai)).
