Tennessee Code Title 43. Agriculture and Horticulture § 43-27-105

(a) The department shall enforce this chapter in a manner that may reasonably be expected to prevent production or distribution of cannabis with THC concentrations exceeding three-tenths of one percent (0.3%) on a dry weight basis, including random inspections and sampling of hemp licensees to ensure compliance with this chapter and rules promulgated under this chapter.

(b) The department shall sample and analyze hemp produced in this state and hemp products distributed in this state for THC concentrations, tested according to protocols prescribed by rule under this chapter. Departmental testing methods shall employ liquid chromatography tandem mass spectrometry, in a manner similarly reliable to post-decarboxylation, to determine a cannabinoid profile of samples tested, including their THC concentrations.
