Wisconsin Hemp Law 2026: What Changes on November 12?
Federal hemp law is scheduled to change on November 12, 2026. The new rule changes how THC is measured. It also creates a 0.4 mg total-THC limit for many final hemp-derived cannabinoid products. These changes can affect Delta-8, hemp-derived Delta-9, and some CBD products sold in Wisconsin.
Congress has enacted a one-month delay to the new federal hemp restrictions. Most of the changes that were scheduled to take effect on November 12, 2026 are now delayed until December 11, 2026. Certain restrictions affecting synthetic or non-naturally occurring cannabinoids remain scheduled for November 12. Congress could still change the law again before the December deadline, and we will continue updating this page as the federal framework develops. [1] [6]
The new federal law does not ban all hemp. It changes the federal definition of hemp, including how THC is measured and which finished cannabinoid products can qualify as hemp. Congress has now delayed the broader federal hemp restrictions through December 11, 2026. The September legislation also separately addresses synthetic hemp derivatives. [1] [2]
What changes under the new federal hemp law?
Congress enacted a narrower federal definition of hemp in November 2025. The original framework was scheduled to take effect on November 12, 2026. Congress has since enacted a temporary delay, moving the broader hemp restrictions to December 11, 2026 while lawmakers continue working toward a longer-term solution. [1]
| Rule | Current framework | New federal framework |
|---|---|---|
| Plant THC standard | Based mainly on delta-9 THC concentration. | Uses total THC, including THCA. |
| Final cannabinoid products | No federal 0.4 mg-per-container rule. | Many finished products above 0.4 mg combined total THC per container would fall outside the new federal definition of hemp. |
| Manufactured cannabinoids | The 2018 definition created legal uncertainty for converted cannabinoids. | The new framework expressly restricts certain cannabinoids manufactured or synthesized outside the plant. |
| Industrial hemp | Legal hemp includes industrial uses. | The new law continues to recognize industrial hemp. |
Congressional Research Service analysis explains that products excluded from the new definition would no longer receive the federal hemp exclusion from the Controlled Substances Act. The federal enforcement and regulatory landscape after implementation is still developing. [2] [3]
1. The law changes the THC measurement
The 2018 federal hemp definition focused on delta-9 THC. The new definition uses total tetrahydrocannabinols and expressly includes THCA in that measurement. The plant-level limit remains 0.3% on a dry-weight basis. [1]
This matters because cannabis can contain multiple forms of THC. A test that looks only at delta-9 THC does not necessarily produce the same compliance result as a total-THC calculation.
2. Final products face a 0.4 mg-per-container test
The new federal framework creates a separate standard for finished hemp-derived cannabinoid products. A finished product can fall outside the federal definition of hemp if the retail container contains more than 0.4 mg combined total of THC and other cannabinoids covered by the new definition. [1]
The 0.4 mg amount applies to the entire finished container. It is not a 0.4 mg limit per serving. [1]
What does “0.4 mg per container” mean?
The new framework applies the threshold to the finished retail container rather than to each individual serving. Federal agencies may provide additional guidance regarding implementation of the new standard. [1]
Assume a bottle contains 30 mL of product and the full bottle contains 3 mg of total THC. For a container-based threshold, the relevant amount is the total contained in the finished retail package rather than the amount in one serving.
This is only an illustration of the per-container concept. It is not a statement about a specific Door County Cannabis Co. product.
What could the new law mean for CBD?
The statute does not say that all CBD is banned. CBD and THC are different cannabinoids. The legal result depends on the formulation of the finished product and how much of the cannabinoids covered by the new federal definition are present in the retail container. [1] [3]
Full-spectrum CBD can contain naturally occurring trace amounts of THC. A full-spectrum product could therefore satisfy the current percentage-based hemp standard while still exceeding the new per-container threshold. Products exceeding the applicable new standard may no longer qualify as hemp once the revised federal definition takes effect. [1]
CBD isolate and broad-spectrum CBD do not necessarily have the same compliance result. The actual cannabinoid content of each finished product matters.
What could the law mean for hemp-derived Delta-9 THC?
Hemp-derived Delta-9 products can be lawful under the current federal framework when they meet the existing definition of hemp. The new framework adds the 0.4 mg-per-container standard for many finished cannabinoid products. Many hemp-derived Delta-9 products sold today contain more than 0.4 mg of THC in a retail container and therefore could fall outside the new federal definition once those restrictions take effect. [1] [2]
What could the law mean for Delta-8 THC?
The new law also changes the treatment of certain cannabinoids made outside the cannabis plant. It excludes cannabinoids that cannot naturally occur in cannabis and addresses certain naturally occurring cannabinoids when they are synthesized or manufactured outside the plant. [1]
This distinction is especially important for commercial Delta-8 products because many are produced through conversion or other manufacturing processes. The federal result can therefore depend on the cannabinoid, the production method and the final product.
The September 2026 legislation delayed the broader federal hemp restrictions through December 11 while separately restricting synthetic hemp derivatives. Because that category is treated differently, manufacturers and retailers should evaluate converted and synthetic cannabinoid products separately rather than assuming the December delay applies identically to every product.
Is all hemp being banned?
No. The new federal definition continues to recognize industrial hemp and uses such as fiber, grain, seed, research and other non-cannabinoid applications. [1]
The most consequential changes concern hemp-derived cannabinoid products intended for human or animal use. That is why describing the legislation simply as a “hemp ban” can be misleading.
What does this mean in Wisconsin?
Wisconsin aligned its hemp framework with federal hemp law, so changes to the federal definition matter directly to which products can continue to qualify as hemp. [5]
Wisconsin ended its state hemp grower licensing program at the end of 2021. Since January 1, 2022, USDA has licensed Wisconsin hemp growers. [4]
In March 2026, Wisconsin Gov. Tony Evers asked Wisconsin's congressional delegation to change the new federal law. His office said Wisconsin hemp businesses support nearly 3,500 jobs and more than $700 million in economic activity. [7]
What is the current federal deadline?
The timeline changed in September 2026.
Congress passed a bipartisan federal funding bill that delays the broader federal hemp restrictions through December 11, 2026. The House completed passage on September 1 after the Senate approved the delay in August.
The legislation also addresses synthetic hemp derivatives separately rather than simply extending every provision of the original framework in the same way.
December 11 is therefore the key date for the broader federal hemp changes currently facing naturally derived hemp products. Congress could still change the law again before then as lawmakers continue discussing a longer-term regulatory approach.
We will continue updating this page as the federal framework develops.
What this change means for Door County Cannabis Co.
Door County Cannabis Co. began with hemp grown on a Wisconsin farm. We built our products around that crop and the customers who supported it.
The federal change now creates an uncertain path for many of the products we sell. It is also affecting our business before November.
In August 2026, Square notified us that it plans to stop supporting businesses that primarily sell CBD and hemp-derived products. Square told us that our account is scheduled to close on November 5, 2026.
We are sharing that information because it shows how the federal change can affect a small hemp business before the statutory effective date. This is our first-hand experience.
We do not know exactly what Door County Cannabis Co. will look like after this season. For now, we are focused on serving our customers, selling through current inventory, and staying informed as Congress considers changes.
A Changing Season for Hemp.
Our current products remain available while inventory lasts. If Door County Cannabis Co. has been part of your routine, this is a meaningful time to stock up and support the Wisconsin farm behind the brand.
Common questions about the Wisconsin hemp law change
Is hemp illegal in Wisconsin in 2026?
No. Hemp is not broadly illegal in Wisconsin. Current hemp products remain subject to existing federal and state law while the new federal definition is delayed. The upcoming federal changes will narrow which cannabinoid products qualify as hemp. [1]
Does the new law ban CBD?
No. The law does not specifically ban cannabidiol (CBD). However, the new finished-product standards could affect some CBD products that contain THC, particularly full-spectrum products. The final formulation, cannabinoid content, and amount present in the retail container all matter. [1] [3]
What happens to Delta-9 gummies under the new federal law?
Many hemp-derived Delta-9 gummies sold today contain more than 0.4 mg of THC in a retail container. If a finished product exceeds the applicable new federal threshold once the revised definition takes effect, it may no longer qualify as hemp under federal law. [1] [2]
What happens to Delta-8 THC?
Delta-8 requires separate attention because many commercial products are made through conversion or manufacturing processes. The new federal framework expressly addresses certain cannabinoids synthesized or manufactured outside the cannabis plant. The legal result depends on the cannabinoid, how it was produced, and the finished product. [1]
What does 0.4 mg per container mean?
The new federal framework includes a threshold based on the amount contained in the finished retail container rather than simply one serving. A multi-serving bottle, bag, or package is therefore evaluated at the container level for this part of the definition. [1]
Has the November 12, 2026 deadline been delayed?
Yes. Congress passed H.R. 6500 and the President signed it into law on September 2, 2026. The legislation extends the current federal hemp definition through December 11, 2026, giving Congress additional time to consider a longer-term approach. [6]
