Required Tests as of 8/31

Required Tests*
Green plant material (flower, kief, trim, etc), concentrates that involve any sort of solvent (CO2, ethanol, hydrocarbon, etc), and infused fats will have new required tests under the new law.
Green Plant Material Required Tests
Moisture Analysis (not required for hash/kief/rosin) Water Activity (new, not required for hash/kief/rosin) Foreign Matter Potency Microbial (limits changing) Mycotoxins (new)



Concentrate (Hydrocarbon, CO2, Ethanol, Food Grade) Required Tests
Potency Mycotoxin Screening (new, only if starting material untested/failed) Residual Solvents (new failure limits/requirement)


Infused Cooking Oil/Fats Required Tests
Potency Microbial (only if made with untested/failed material) Mycotoxin screening (new, only if made with untested/failed material)


New Failure Thresholds
The failure criteria for residual solvent testing and microbial testing are changing and the mycotoxin screening adds a new failure limit to be aware of.
