Understanding Federal vs. State Law
Kratom is federally unscheduled. Wisconsin acted independently in 2014 to classify mitragynine and 7-hydroxymitragynine as Schedule I controlled substances under Wis. Stat. Section 961.14. Schedule I in Wisconsin treats these alkaloids the same as heroin or LSD for prosecution purposes. Federal legality provides no protection inside Wisconsin.
KCPA Section
No KCPA has been enacted in Wisconsin. AB 393 was introduced in the 2023, 2024 session as a potential consumer protection framework but did not pass before adjournment. No companion bill has advanced.

| 2023, 2024 session | AB 393 introduced as a possible KCPA framework. Did not pass. |
Penalties
Schedule I possession in Wisconsin is a felony. Penalty severity scales with quantity and intent. Sale and manufacturing carry higher penalties under Wis. Stat. Chapter 961.
Buying & Shipping to Wisconsin
Do not ship kratom to a Wisconsin address. Most reputable vendors block Wisconsin at checkout. Receiving kratom in Wisconsin exposes the recipient to Schedule I felony possession penalties even if the product was purchased legally elsewhere.
