The United States Department of Agriculture has issued a directory of 37 testing facilities.
According to the website listing the laboratories, any laboratory testing hemp for THC concentration under the U.S. Domestic Hemp Production Program must be registered with the Drug Enforcement Administration (DEA) to handle controlled substances. The directory they list summarizes hemp testing laboratories who are registered with the DEA. This directory is provided for informational purposes only.
Licensed hemp producers should first verify with their licensing body (State or Tribe) where their hemp may be tested. If you are a DEA registered hemp testing laboratory and would like to be added to this directory, please send a message to [email protected]
In addition, the new federal crop sampling and testing provisions say that:
- Sampling of hemp flower material must be conducted within 15 days before anticipated harvest by a USDA-approved sampling agent, which could be a federal, state or local law enforcement body.
- States may submit alternative sampling and testing protocols for consideration if they could result in comparable or similarly reliable testing results.
Hemp crops grown under the 2014 pilot program are not required to be tested in DEA-registered labs.
DEA-registered hemp testing laboratories that would like to be added to the directory can email [email protected]
