UT SB0048

7-hydroxymitragynine becomes a Schedule I controlled substance when concentrated above 0.4% of the total kratom alkaloid composition in any product, including synthetic versions

Mitragynine pseudoindoxyl, including synthetic versions, is added to Schedule I controlled substances regardless of concentration level

Kratom processors are prohibited from selling products that would be considered controlled substances under these new thresholds, replacing the previous 2% limit on 7-hydroxymitragynine in the alkaloid fraction

Adds a new definition for "total kratom alkaloid composition" meaning the total amount of all alkaloids derived from the Mitragyna speciosa plant

Effective date is May 6, 2026, or earlier if approved by two-thirds of all members elected to each house
