Overview
Federal legislation enacted in November 2025 establishes significant changes to the federal definition of hemp, including new restrictions on total tetrahydrocannabinol (THC) content and certain cannabinoids. These changes affect consumable hemp products currently manufactured, distributed, or sold in Iowa.
The Iowa Department of Health and Human Services (HHS) has prepared these frequently asked questions to explain the changes and how they will affect Iowa's Consumable Hemp Program.
Important Notice: Beginning on the applicable federal implementation dates:
- Products exceeding the new federal limits will be removed automatically from Iowa's Master Product List and will no longer be accepted for compliance review.
- Products meeting federal and Iowa requirements will remain on the Master Product List and be eligible for compliance review.

- The new federal law makes three major changes:
- Lower THC limits: Establishes a limit of 0.4 milligrams (mg) per container, including THC and certain other cannabinoids with similar effects.
- Changes how THC is measured: Requires total THC to be considered, including THCA, rather than only delta-9 THC.
- Restricts certain cannabinoids: Excludes certain synthetic or chemically converted cannabinoids from the federal definition of hemp.
- Products that no longer meet the federal definition of hemp may become subject to federal controlled-substance laws.
- The new federal requirements take effect on two dates:
- 12:00 AM, November 12, 2026: Certain cannabinoids that cannot naturally be produced by cannabis will no longer qualify as hemp under federal law.
- 12:00 AM, December 11, 2026: The new 0.4 mg per-container limit and total THC requirements take effect.
- Registrants should review their products and prepare to comply with the new requirements by the applicable dates.
- The new federal requirements are more restrictive than Iowa's existing THC limits.
| Requirement | Iowa Law | New Federal Definition |
|---|---|---|
| THC per serving | 4mg | No separate serving limit established by this provision |
| THC per container | 10mg | 0.4mg for covered final products |
| THC concentration | 0.3% total THC by dry weight | 0.3% total THC by dry weight, subject to additional exclusions |
The new federal requirements include additional restrictions on certain cannabinoids beyond THC.
- Example: A beverage containing 4 mg of THC may meet Iowa's limits but would exceed the new federal 0.4 mg per-container limit.
- Iowa's existing THC limits will remain unchanged, however Iowa’s hemp laws may not be construed or applied in conflict with Federal law and related regulations.
- Beginning on the applicable federal implementation dates:
- Products exceeding federal limits will no longer be accepted for compliance review and will be removed from the Master Product List.
