Wisconsin, USA hemp laws: quick overview

Wisconsin law defines “hemp” in Wis. Stat. § 94.55(1) (2025) as Cannabis sativa L. and derivatives with delta‑9‑THC concentration of not more than 0.3% dry weight or the maximum allowed under federal law up to 1%, whichever is greater, tested post‑decarboxylation or similarly reliable methods ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)). The 2019 Wisconsin Act 68 (effective November 28 2019) aligned state law with the 2018 Farm Bill, authorized DATCP to license and regulate hemp, and imposed truth‑in‑labeling requirements under Wis. Stat. § 94.55(3m) ([content.govdelivery.com](https://content.govdelivery.com/accounts/WIGOV/bulletins/26e383a?utm_source=openai)). As of January 1 2022, Wisconsin’s hemp program transitioned to USDA oversight; DATCP no longer issues licenses, though recordkeeping under Wis. Admin. Code ch. ATCP 22 remains for prior years ([datcp.wi.gov](https://datcp.wi.gov/Pages/Programs_Services/Hemp.aspx?utm_source=openai)). Under Wis. Stat. § 94.55(2g), negligent violations—such as producing hemp over 0.3% Δ9‑THC—require corrective plans; three negligent violations in five years result in a five‑year production ban ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)). Wis. Stat. § 961.55 mandates seizure and destruction of crops testing more than 0.7% above the permissible limit (i.e. > 1.0%) ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-961/section-961-55/?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products are allowed under USDA‑regulated program. No state‑specific age verification or retailer registration requirements are in place; DATCP no longer licenses retailers. However, truth‑in‑labeling applies to all sales.

Testing & COA guidance

Testing must use post‑decarboxylation or similarly reliable methods to measure delta‑9‑THC, including conversion from THCA, per Wis. Stat. § 94.55(1) and federal standards ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)). Sampling must be conducted by USDA‑certified agents since Jan 1 2022 ([datcp.wi.gov](https://datcp.wi.gov/Documents2/LWCBMeetingMaterialsDecember2021.pdf?utm_source=openai)). COA retention and ISO 17025 accreditation are not specified in state law; follow USDA requirements.

What to buy

Products derived from hemp that comply with Δ9‑THC ≤ 0.3% dry weight (or federal max up to 1%) are legal. This includes CBD oils, tinctures, edibles, fiber, grain, and approved hemp varieties.

What to avoid

Avoid products exceeding Δ9‑THC thresholds (over 0.3% or federal max). State law does not specifically address delta‑8, delta‑10, THCA flower, or HHC—status is unknown. Smokable hemp is not separately regulated; legality depends on THC content.

How to shop compliant, tested hemp

• Wisconsin defines hemp as Cannabis sativa L. with Δ9‑THC ≤ 0.3% dry weight or federal max up to 1% (whichever greater) per Wis. Stat. § 94.55(1) (2025)
• Hemp producers must be licensed under USDA plan since Jan 1 2022; DATCP no longer issues licenses
• Truth‑in‑labeling required under 2019 Wis. Act 68 (Wis. Stat. § 94.55(3m))
• Negligent violations (Δ9‑THC > 0.3%) trigger corrective plans; three in five years leads to 5‑year ban
• Crops exceeding 0.7% above limit (i.e. > 1.0%) are subject to seizure and destruction per Wis. Stat. § 961.55
