Hemp FAQ

Yes, any person who grows hemp in Tennessee, regardless of the quantity, is required to have a hemp grower license.  

No, processors are not required to be licensed or registered with TDA for processing hemp. If you plan on making a product for human consumption, you are required to be licensed as a food manufacturing facility. Contact TDA’s food and dairy section for more information on those licenses: (615) 837-5193 or NewFood.Business@TN.gov 

No, TDA does not issue licenses for the sale of processed hemp products. TDA regulates rooted hemp or growing hemp.

You can apply for a hemp grower’s license at any time. The application can be found here. A complete application and license fee are required before a license can be issued.

You must have a movement permit before transporting rooted hemp plants and/or transporting harvested hemp to a processor for commercial purposes. It takes only a few minutes to apply for a movement permit online. Although it’s not required in all instances, we strongly encourage you to have a permit before moving any plants or plant material.

TDA does not require any testing to the soil before obtaining a license. The person purchasing your hemp may require soil tests for pesticide residues or heavy metals. Nutrient soil tests are can be sent to UT extension for testing while heavy metals and pesticide tests require a private lab. You can use the internet to find a lab for those tests or ask a processor.
