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 the Department of Agriculture, Trade and Consumer Protection (DATCP) to license hemp producers, regulate planting, testing, processing, transport, and enforce negligent violations, including disposal and inspections ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)). Current Wisconsin law does not set a total‑THC limit or per‑serving mg threshold; it relies solely on delta‑9‑THC percentage. The Controlled Substances Act (Ch. 961) exempts hemp and its derivatives from THC scheduling when meeting § 94.55’s definition ([3chi.com](https://www.3chi.com/is-delta-8-thc-legal-in-wisconsin/?utm_source=openai)). However, cannabinoids like delta‑8, delta‑10, HHC, and THCa are not explicitly addressed and remain in a legal gray area, though widely available under the hemp definition ([wisconsinstatecannabis.org](https://wisconsinstatecannabis.org/thc/delta-8?utm_source=openai)). Legislation introduced in 2025–26 (AB‑606/SB‑681 and SB‑682) proposes a new “intoxicating hemp products” category under § 94.56, imposing a three‑tier regulatory system akin to alcohol, requiring licensing, testing, labeling, potency caps, and restricting sales to those 21 and older ([aclu-wi.org](https://www.aclu-wi.org/legislation/ab-606-hemp-regulation/?utm_source=openai)). These bills are pending and not yet law as of May 3, 2026.

Shipping guidance

Inbound shipments of hemp products are allowed if they meet the Δ9 ≤ 0.3% dry‑weight definition. No state‑specific age verification or retailer registration rules for shipping are currently in effect. Pending legislation would impose age 21+ verification and licensing, but not yet law ([aclu-wi.org](https://www.aclu-wi.org/legislation/ab-606-hemp-regulation/?utm_source=openai)).

Testing & COA guidance

Wisconsin DATCP rules (under § 94.55) require testing using post‑decarboxylation or similarly reliable methods for Δ9‑THC concentration; rules for testing panels, ISO 17025 accreditation, COA retention are not specified in statute and remain to be defined by DATCP rulemaking ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai)).

What to buy

Products containing hemp‑derived cannabinoids with Δ9‑THC ≤ 0.3% dry weight are legal. This includes CBD, delta‑8, delta‑10, HHC, THCa products, edibles, vapes, tinctures, and flower, provided they meet the Δ9 threshold.

What to avoid

Products exceeding Δ9‑THC > 0.3% dry weight are illegal. Marijuana‑derived THC products remain prohibited. No explicit bans on delta‑8, delta‑10, HHC, or THCa yet, but they occupy a legal gray area. Watch for future restrictions under pending intoxicating hemp legislation.

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% (WI Stat § 94.55(1), effective 2025) ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai))
• Hemp producers must be licensed by Wisconsin DATCP under § 94.55(2)(am), with rules for testing, disposal, inspections ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai))
• No explicit state limit on total THC or per‑serving mg; state follows Δ9 threshold only ([law.justia.com](https://law.justia.com/codes/wisconsin/chapter-94/section-94-55/?utm_source=openai))
• Delta‑8, Delta‑10, HHC, THCa are not specifically regulated—legal under current hemp definition but in a gray area ([wisconsinstatecannabis.org](https://wisconsinstatecannabis.org/thc/delta-8?utm_source=openai))
• Pending legislation (AB‑606/SB‑681 and SB‑682) would create a regulated intoxicating hemp framework with age 21+, licensing, testing, potency caps ([aclu-wi.org](https://www.aclu-wi.org/legislation/ab-606-hemp-regulation/?utm_source=openai))
