Ohio, USA hemp laws: quick overview

Ohio’s hemp law was significantly updated by Senate Bill 56 (136th General Assembly), signed December 19 2025 and effective March 20 2026. The definition of “hemp” now aligns with federal law: Cannabis sativa L. and derivatives with total THC (including THCa) not exceeding 0.3% on a dry‑weight basis (Ohio Rev. Code § 928.01(C)) ([codes.ohio.gov](https://codes.ohio.gov/ohio-revised-code/chapter-928?utm_source=openai)). The law also imposes a per‑container cap: final hemp‑derived cannabinoid products must contain no more than 0.4 mg total THC per container (Ohio Rev. Code § 928.01(C)(4)) ([codes.ohio.gov](https://codes.ohio.gov/ohio-revised-code/chapter-928?utm_source=openai)). Licensing requirements are codified in Ohio Rev. Code § 928.02: both cultivation and processing of hemp require a license issued by the Director of Agriculture, valid for three years, with exemptions for research by universities or the Department (effective March 20 2026) ([codes.ohio.gov](https://codes.ohio.gov/ohio-revised-code/chapter-928?utm_source=openai)). The Department must adopt rules covering testing, labeling, packaging, transportation, and disposal under § 928.03 (effective March 20 2026) ([codes.ohio.gov](https://codes.ohio.gov/ohio-revised-code/chapter-928?utm_source=openai)). Testing rules are set in Ohio Administrative Code Rule 901:14‑2‑13: all hemp products (excluding fiber or seed‑only) must be tested for microbial contaminants, cannabinoid potency (including Δ9‑THC, THCa, CBD, CBDA, and other labeled cannabinoids), mycotoxins, heavy metals, and residual solvents; COAs must meet Rule 901:14‑2‑15 requirements, including ISO certification and batch tracking ([codes.ohio.gov](https://codes.ohio.gov/ohio-administrative-code/rule-901%3A14-2-13?utm_source=openai)). The Department’s lab is the official regulatory lab, with authority to contract third‑party labs; non‑compliant samples must be destroyed ([codes.ohio.gov](https://codes.ohio.gov/ohio-administrative-code/rule-901%3A14-1-10?utm_source=openai)).

Shipping guidance

Ohio law does not explicitly restrict inbound shipments of hemp products that meet state THC limits. However, all transported hemp or hemp‑derived products must comply with rules adopted under § 928.03, including packaging and labeling requirements. Age verification and retailer registration are not specified in statute; licensing applies to cultivators and processors, not retailers.

Testing & COA guidance

Testing is mandatory for all hemp‑derived cannabinoid products (excluding fiber or seed‑only) under OAC Rule 901:14‑2‑13. Required panels include microbial contaminants, cannabinoid potency (Δ9‑THC, THCa, CBD, CBDA, other labeled cannabinoids), mycotoxins, heavy metals, and residual solvents. COAs must follow Rule 901:14‑2‑15, including ISO certification number, batch/lot number, test dates, and cannabinoid profile. The Department’s lab is the official regulatory lab; third‑party labs may be used under contract. Non‑compliant batches must be destroyed.

What to buy

Products compliant with Ohio law include hemp‑derived cannabinoid products with total THC ≤ 0.3% dry‑weight and ≤ 0.4 mg total THC per container, tested by ISO‑certified labs, properly labeled and packaged per Department rules. This includes oils, tinctures, edibles, topicals, and other non‑intoxicating forms derived from hemp.

What to avoid

Avoid any hemp‑derived product exceeding 0.3% total THC on dry weight or 0.4 mg total THC per container. Intoxicating hemp products (exceeding thresholds) are prohibited. Ohio law does not specifically address Δ8, Δ10, HHC, or THCa by name—status unknown. Smokable hemp flower is not explicitly banned, but must meet THC thresholds.
