Hemp Research Program

​Beginning January 1, 2022, hemp growers will be licensed by the U.S. Department of Agriculture (USDA) and hemp processors will no longer require a license. Learn more about this transition​.​


  • September 30, 2021​: A webinar was held on September 15 for hemp growers to learn how to locate and work with their local U.S. Department of Agriculture (USDA) office and how to apply for a USDA hemp license. The webinar recording is available at https://www.ams.usda.gov/rules-regulations/hemp/licensed-producers

  • September 2, 2021: Wisconsin hemp program transitioning to USDA in 2022
  • Variety approval forms required from all growers: In 2021, all growers must submit a variety approval form and report the varieties they intend to plant, even if those varieties are already approved. See the reporting and recordkeeping webpage for instructions on submitting your variety approval form. Learn more about varieties already approved in writing by DATCP.
  • Harvest notification form: You must notify DATCP​ 30 days before you harvest each lot of hemp so DATCP has time to​ sche​​dule testing. Use the online process at MyDATCP to submit your 30-day harvest notifications.​
  • Sampling: Your lot of hemp must contain 10 or more female plants and, of those plants, must contain enough plant material for DATCP to take samples for testing. Samples shall be of a sufficient size to allow for one test and one retest pursuant to ATCP 22.10(4)​. The regulatory sample must be taken before you can harvest each lot of hemp, and is a collection of the top 5 inches of flower from at least 10 female plants per lot. The exact number of cuttings per lot varies based on the size and the uniformity of a lot.
  • Submit documents online: You can no longer email location changes, planting reports, or 30-day harvest notifications. If you have a hemp license and a 2020 annual registration, you can submit these documents using MyDATCP​.​​

Hemp Research Program​

DATCP's Hemp Research Program requires both hemp growers and processors to obtain one-time licenses, and register each year they intend to plant and/or process hemp. Growers and processors must also pass criminal background checks and pay fees to participate in the program. As participants in the research program, growers and processors are required to:

  • Destroy crops that test higher than 0.3% total delta-9 THC, as determined by regulatory testing.
  • Obtain a hemp grower or processor license.
  • Pay for and pass a crimina​l background check before the initial license is issued.
  • Pay license fees and/or annual registration fees.
  • Submit a signed research agreement and a research summary.
  • Hemp growers: Submit a variety approval form at least 30 days prior to planting to obtain approval for that variety from DATCP.
  • Hemp growers: Submit a planting report by July 1 and within 30 days of planting hemp at each lot*.
  • Hemp growers: Submit a harvest notification form at least 30 days before harvest.
  • Obtain written permission before voluntarily destroying crops. Submit a destruction notification prior to voluntary destruction of hemp that is not otherwise ordered destroyed by DATCP. Then, complete and submit a destruction form along with visual evidence promptly after the destruction event. 
  • Provide access to DATCP hemp inspectors to obtain a hemp sample for each lot*.
  • Pay a $250 initial sampling fee for each lot* sampled by DATCP.
  • Pay a $300 sampling fee for each remediated lot* sampled by DATCP.
  • Pay a $200 retest fee for each lot where a new sample is not required.​
  • Submit a final production/processing report at the end of the growing season and prior to registering for the following growing season.

*A contiguous area in a field, greenhouse, facility, or growing structure containing the same variety or strain of hemp ​throughout the area.

There is inherent risk associated with participation in a research program focusing on a new crop and with participation in this research pilot program. There is no guarantee that your crop will pass the regulatory THC test.
