FDA Misses Deadline for Hemp Cannabinoid Lists

The U.S. Food and Drug Administration remains more than six months late in publishing required hemp guidance, the Congressional Research Service noted in August, as a revised federal hemp definition approaches its November effective date.

Federal spending legislation enacted in 2025 gave the FDA 90 days to consult with other agencies and publish three lists covering:

• Cannabinoids that cannabis can naturally produce
• Naturally occurring THC-class cannabinoids
• Other cannabinoids with effects similar to THC or marketed as having similar effects

The agency was also directed to provide more specific guidance on the meaning of “container” for final hemp-derived cannabinoid products. Under the law, a container is generally the innermost package that directly holds a retail product, such as a bottle, jar, bag, packet, box, can, carton or cartridge.

The deadline expired on February 10, 2026. In an updated report dated August 17, the Congressional Research Service confirmed that the required FDA materials had still not been published.

The distinction is important because the revised federal definition sets a limit of 0.4 milligrams of total THC per container. Without detailed guidance, businesses may have difficulty determining which cannabinoids fall within the new restrictions and how the limit applies to different packaging formats.

Earlier in 2026, a Department of Health and Human Services representative said the agency intended to publish the lists in the Federal Register.

“It is difficult to comply with the law while key definitions are still in question,” Jim Higdon, co-founder of Cornbread Hemp, says.

“Without knowing the definition of container or exact list of cannabinoids that are covered by the ban, how does one comply?”

His comment reflects the industry’s central concern: companies are being asked to prepare for a major federal policy change without the technical information needed to evaluate products and packaging.

For hemp businesses, 0.3% delta-9 THC by dry weight has been the key federal benchmark since the 2018 Farm Bill. Congress changed course last year, and a new cap of 0.4 milligrams of total THC per container is scheduled to take effect on November 12, 2026.

The Senate has since approved funding legislation that would postpone most of the change until December 11. However, the House has not approved that provision, so it has not become law.

Several lawmakers have also introduced proposals to establish a regulated federal framework for hemp-derived consumer products. None has yet advanced through congressional leadership, leaving businesses to prepare for the existing November deadline while awaiting the overdue FDA guidance.
