Wisconsin, USA hemp laws: quick overview

Wisconsin Statute § 94.55 (2025) defines “hemp” as Cannabis sativa L. and derivatives with delta‑9‑THC concentration not more than 0.3 % dry weight or the federal maximum up to 1 %, whichever is greater, tested post‑decarboxylation; effective as of 2025 statute text ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)). The statute authorizes hemp activities—planting, processing, transporting, selling—subject to USDA licensing; Wisconsin DATCP ceased issuing state hemp licenses effective January 1 2022 ([datcp.wi.gov](https://datcp.wi.gov/Pages/Programs_Services/Hemp.aspx?utm_source=openai)). Truth‑in‑labeling provisions under § 94.55(3m) prohibit mislabeling or false claims about THC content, with civil and injunctive remedies ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)). DATCP administrative rules (ATCP 22.10) require sampling and testing of hemp lots; non‑compliant lots must be destroyed or remediated, with remediation defined and destruction procedures specified ([caselaw.findlaw.com](https://caselaw.findlaw.com/court/wi-court-of-appeals/117884226.html?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp are allowed under federal USDA licensing; Wisconsin does not impose additional state shipping restrictions. No state age verification or retailer registration requirements exist for hemp‑derived cannabinoid products at the state level.

Testing & COA guidance

Testing is required under DATCP rules (ATCP 22.10): each lot must be sampled and tested using DATCP‑approved methods; non‑compliant lots must be remediated or destroyed. Laboratories must follow DATCP protocols; no explicit ISO 17025 requirement is stated in state law. Certificates of analysis are issued by DATCP to licensed growers; retention requirements follow USDA/DATCP recordkeeping rules ([caselaw.findlaw.com](https://caselaw.findlaw.com/court/wi-court-of-appeals/117884226.html?utm_source=openai)).

What to buy

Products derived from hemp as defined (Δ9‑THC ≤ 0.3 % dry weight or federal max up to 1 %) are legal. This includes CBD, hemp flower, extracts, and isomers contained within hemp.

What to avoid

Products exceeding the hemp definition (e.g., Δ9‑THC > 0.3 % dry weight or above federal max) are controlled substances. No state bans on specific cannabinoids like delta‑8, delta‑10, THCa, HHC—status is unknown under state law. Local jurisdictions (e.g., Wood County) may restrict sales to under‑21 or impose zoning limits ([dhs.wisconsin.gov](https://www.dhs.wisconsin.gov/scaoda/derived-psychoactive-cannabis-products-report-9-27-24.pdf?utm_source=openai)).
