Wisconsin, USA hemp laws: quick overview

Wisconsin Statute § 94.55 (2025) defines “hemp” as Cannabis sativa L. and any part thereof with delta‑9‑THC concentration not more than 0.3% dry weight, or the maximum allowed under federal law up to 1%, whichever is greater, tested via post‑decarboxylation or similar methods ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)). The statute authorizes planting, growing, processing, transporting, selling, and importing hemp to the fullest extent allowed under federal law, contingent on licensing by the Department of Agriculture, Trade and Consumer Protection (DATCP) if required ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)). Under Wis. Stat. § 961.55, if a hemp crop exceeds the permissible THC limit by more than 0.7%, the entire crop may be seized and destroyed, with written documentation of test results required prior to destruction ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-961/section-961-55/?utm_source=openai)). The statute also mandates truth‑in‑labeling: mislabeling or inaccurate claims about hemp products can result in civil forfeiture or injunctive relief, with penalties up to $1,000 per violation ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products are allowed if compliant with state THC limits and federal law. Retailers must hold appropriate licensing (DATCP or USDA‑approved). Age verification is required for hemp‑derived intoxicating cannabinoids under local ordinances (e.g., must verify purchaser is 21+).

Testing & COA guidance

Hemp must be tested using post‑decarboxylation or similarly reliable methods to determine delta‑9 THC concentration per Wis. Stat. § 94.55(1) ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)). Exceeding limits triggers remediation or destruction. Specific lab accreditation (e.g., ISO 17025) is not specified in statute; recordkeeping for DATCP‑registered growers (pre‑2022) must be retained for three years per ATCP 22 ([datcp.wi.gov](https://datcp.wi.gov/Pages/Programs_Services/Hemp.aspx?utm_source=openai)).

What to buy

Products containing hemp‑derived CBD or other non‑intoxicating cannabinoids with delta‑9 THC ≤ 0.3% (or federal max up to 1%) are legal. Licensed producers may sell compliant hemp flower, extracts, and derivatives.

What to avoid

Products exceeding delta‑9 THC limits (>0.3% or federal max) are illegal. Hemp‑derived intoxicating cannabinoids (delta‑8, delta‑10, THCA, HHC, etc.) may be sold only to persons 21+ and are restricted by local ordinances; some municipalities prohibit sales near youth‑serving locations ([dhs.wisconsin.gov](https://www.dhs.wisconsin.gov/scaoda/derived-psychoactive-cannabis-products-report-9-27-24.pdf?utm_source=openai)).

How to shop compliant, tested hemp

• Delta‑9 THC limit: ≤ 0.3% dry weight (or federal max up to 1%) per Wis. Stat. § 94.55(1)
• Hemp producers must be licensed by DATCP or USDA‑approved program
• Negligent over‑THC violations trigger remediation; >0.7% above limit triggers crop destruction per Wis. Stat. § 961.55
• Truth‑in‑labeling enforced; mislabeling penalties up to $1,000 per violation
• Hemp‑derived intoxicating cannabinoids (e.g., delta‑8, delta‑10, THCA, HHC) restricted for under‑21 sales per local ordinances
