"Industrial hemp" means the plant, Cannabis sativa L., and any part of the plant, including the seeds thereof, and all derivatives, extracts, cannabinoids, isomers, acids, salts and salts of isomers, whether growing or not, with a total delta-9 tetrahydrocannabinol concentration of not more than three-tenths of one percent (0.3%) on a dry weight basis. "Acceptable Hemp THC Level" means when a laboratory tests a sample, it shall report the total delta-9 tetrahydrocannabinol content concentration level on a dry-weight basis and the measurement of uncertainty. The acceptable hemp THC level, for the purpose of compliance with the requirements of the state hemp plan, is when the application of the measurement of uncertainty to the reported total delta-9 tetrahydrocannabinol content concentration level on a dry-weight basis produces a distribution or range that includes 0.3% or less. "Decarboxylated" means the completion of the chemical reaction that converts THC-acid (THCA) into total delta-9-THC, the intoxicating component of cannabis. The decarboxylated value is also calculated using a conversion formula that sums total delta-9-THC and eighty-seven and seven tenths (87.7) percent of THCA.
