Missouri Industrial Hemp amendments approved

Hemp growers to receive additional flexibility and remediation options

Today, the Missouri Department of Agriculture announced federal approval of the state’s amendment to the Industrial Hemp Plan. With the approval, the U.S. Department of Agriculture’s Agriculture Marketing Service affirmed that Missouri’s amended plan complies with federal law and regulations.

The entire amended Missouri State Plan can be reviewed here

Key changes include:

  • Increasing the pre-harvest window for compliance sampling from 15 to 30 days
  • Allowing remediation options for eligible crops that initially test above 0.3% total THC
  • Updating requirements for testing laboratories to be ISO 17025 accredited and after 12/31/2022, also registered with the Drug Enforcement Agency (DEA)

As one of the first plans approved under the new federal final rule, Missouri’s producers will help launch a new era of domestic industrial hemp production. Remaining states, tribes and territories must have plans approved by the end of the year, or defer regulatory authority to the U.S. Department of Agriculture.


Last year, more than 200 Producer Registrations were issued in Missouri and 811 acres of industrial hemp were planted – including varieties grown for flower, fiber, seed, and grain. As a national leader in third-party sampling, the program certified 80 Certified Industrial Hemp Samplers across 38 counties – allowing for increased flexibility for Missouri’s producers, and a business opportunity for those certified.
