[Wisconsin Legislative Council issue brief, May 19, 2026:] [s. 94.55(1) defines hemp as the Cannabis plant with THC up to 0.3 percent on a dry weight basis; the state definition] "continues to focus solely on delta-9 THC concentration rather than on total THC" [and] "the state's 'hemp' definition does not automatically change with a change to the federal definition." [Statute text not separately fetched.]

In this section, "hemp" means the plant Cannabis sativa L. and any part of that plant, including the seeds thereof and all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers, whether growing or not, with a delta-9-tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis or the maximum concentration allowed under federal law up to 1 percent, whichever is greater, as tested using post-decarboxylation or other similarly reliable methods. "Hemp" does not include a prescription drug product that has been approved by the U.S. food and drug administration.

(am) The department shall issue licenses to hemp producers if hemp producers are required to hold a license to produce hemp under federal law and if the secretary of the U.S. department of agriculture has approved this state's hemp program. If the department issues such licenses, no person may produce hemp without a license from the department.
