The federal hemp ban takes effect in two steps. On November 12, 2026, intermediate and final products with cannabinoids the cannabis plant cannot produce naturally stop counting as hemp. On December 11, 2026, the rest follows, including a total THC limit.
Two laws set these dates, Public Law 119-37 of November 2025 and Public Law 119-103 of September 2026. The September law delayed only part of the change, and only until December 11. A product left outside the definition would be regulated as marijuana under the Controlled Substances Act (CSA), according to the Congressional Research Service (CRS).
Since the new test counts total THC, including THCA, a passing delta-9 result no longer settles hemp status. I advise on cannabis under federal food and drug law and the 2018 farm bill as part of OFW Law’s cannabis and hemp regulatory counsel. What follows reflects the law as of October 8, 2026.
Two Dates, Two Groups of Products
Section 781 of Public Law 119-37 amended the hemp definition in 7 U.S.C. 1639o, effective 365 days after enactment. It sits in Division B, the fiscal year 2026 agriculture funding act. Counted from November 12, 2025, the whole definition would have applied on November 12, 2026.
Public Law 119-103 changed that timing in part. Section 2019 of that law narrows the definition until December 11, 2026. Until then, it applies only to products with “cannabinoids that are not capable of being naturally produced” by the plant.
Every other part of the federal hemp ban, including the total THC test and both caps, takes effect on December 11. Only the November 12 exclusion keeps its original date. December 11 also governs natural cannabinoids synthesized or manufactured outside the plant and intermediate products sold to consumers.
| Part of the new definition | What it reaches | In force from |
|---|---|---|
| Exclusion for cannabinoids not capable of being naturally produced by the plant | Intermediate and final products that contain them | November 12, 2026 |
| Limit of not more than 0.3 percent total THC, including THCA, on a dry weight basis | The plant and its derivatives, extracts and cannabinoids | December 11, 2026 |
| Exclusion for natural cannabinoids synthesized or manufactured outside the plant | Intermediate and final products that contain them | December 11, 2026 |
| Cap of 0.3 percent combined total THC and similar-effect cannabinoids | Intermediate products | December 11, 2026 |
| Cap of 0.4 milligrams combined total THC and similar-effect cannabinoids per container | Final products | December 11, 2026 |
| Exclusion for intermediate products sold as final products or to consumers | Those intermediate products, whatever their THC content | December 11, 2026 |
What the November 12 Exclusion Covers
The November 12 date reaches one category, intermediate and final products with cannabinoids the plant cannot produce naturally. Natural cannabinoids made outside the plant wait until December 11. Which compounds sit in the November category depends on the first of several items the law assigned to FDA.
FDA’s first list, due within 90 days of the November 2025 enactment, was to name every cannabinoid the plant is known to produce naturally. The same deadline covered two more cannabinoid lists and more detail on the term container. As of September 28, 2026, the CRS In Focus report on the new hemp definition stated that “such a list has not been published.”
How the New THC Limits Work
THCA and the Total THC Test
The 2018 farm bill limited delta-9 THC alone, to not more than 0.3 percent by dry weight. From December 11, the limit stays at 0.3 percent but covers total THC, which the statute says includes “tetrahydrocannabinolic acid,” better known as THCA. Plant material above that level, with THCA counted, is not hemp, so a crop or extract that passed on delta-9 alone can now fail.
Caps for Intermediate and Final Products
Intermediate products are meant to be mixed into something else before use. From December 11, an intermediate product is excluded above 0.3 percent combined total of THC, counting THCA, and similar-effect cannabinoids. Selling one as a final product, or straight to consumers, excludes it whatever its THC content.
The federal hemp ban caps final products per container, not per serving. A final product is excluded if one container holds more than 0.4 milligrams combined of total THC and similar-effect cannabinoids. The other cannabinoids in both caps are those the Department of Health and Human Services (HHS) finds act like THC, or are marketed that way.
The container is the innermost packaging that touches a final retail product, such as a jar, can or cartridge. The statute leaves out “bulk shipping containers” and outer wrappings not essential to the retail sale. Congress also told FDA to publish more detail on the term.
Industrial Hemp, Growers and FDA-Approved Drugs
Industrial hemp is named inside the new hemp definition, which also carries the 0.3 percent total THC limit. The term covers plants grown for the stalk and its fiber, or for grain, oil and other non-cannabinoid seed products, along with microgreens. Research plants kept out of commerce count too, as does seed grown only for these uses.
The industrial label matters for products. Industrial hemp sits outside the definition of a hemp-derived cannabinoid product. Growers still need a state, tribal or USDA license or authorization to grow hemp, says the hemp page of USDA’s Agricultural Marketing Service.
USDA has put off enforcing its DEA-registered lab testing rule until December 31, 2026. From December 11, viable seeds from a plant whose total THC, including THCA, exceeds 0.3 percent on a dry weight basis are not hemp. Microgreens are tied to that same seed threshold.
The product definition also leaves out drugs approved under section 505(c) or (j) of the Federal Food, Drug, and Cosmetic Act (FD&C Act). FDA’s wider power over cannabis products, the subject of our earlier post on FDA warning letters to CBD and delta-8 THC companies, stays in place. FDA Commissioner Makary wrote on April 1, 2026, that this authority “was unaffected” by the new definition.
Where the Delay Effort Stands in Congress
The delay that passed in September 2026 is partial. It holds back most of the federal hemp ban only until December 11, leaving the November 12 exclusion on its original date. Each bill in Congress that would go further is a proposal until it passes and is signed.
As of September 28, 2026, CRS listed H.R. 7024, H.R. 7010 and Senate bill 3686 as bills that would delay the definition two more years. A fourth, H.R. 6209, would repeal the changes outright. The House-passed fiscal year 2027 agriculture funding bill, H.R. 8646, has no provision to delay the definition, CRS reports.
Other bills would rewrite the limit itself, with Senate bill 2112 allowing up to 1 percent delta-9 THC. Under H.R. 9830 the ceiling would be 1 percent total THC. Senate bill 4315 takes another route, deferring to state definitions of hemp.
Views on timing differ, CRS reports. Some hemp industry groups have generally backed a delay, giving Congress time to pass a different set of rules for hemp products. Others, including attorneys general in several states, opposed one and said states have changed or aligned their laws to fit the new definition.
The December 18, 2025 executive order also directs work with Congress on the definition of final products. Our analysis of the December 2025 executive order explains why that direction did not change Section 781. Until a new bill passes and is signed, the dates in Public Law 119-37 and Public Law 119-103 are the ones that control.
What Happens to Products That Are No Longer Hemp
A product the federal hemp ban excludes does not leave federal law behind. Excluded products are not hemp and “would instead be subject to regulation under the CSA as marijuana,” in CRS’s reading. For the November 12 group, CRS dates that status to November 12.
Marijuana’s federal status has changed in part, a change CRS notes would also reach hemp products classified as marijuana. Since April 28, 2026, a DEA rule has put FDA-approved drugs made with marijuana in Schedule III, along with marijuana under a state medical license. Any other form stays in Schedule I, as our post on the final order moving certain marijuana products to Schedule III explains.
The April rule reaches non-hemp marijuana only in an FDA-approved drug or under a state medical license. Whether it reaches former hemp products sold under such a license is open. We work through that with each company before a line moves.
How federal law enforcement will act on the new prohibitions “remains unclear,” CRS wrote in December 2025. Intoxicating hemp products sold after the change “could be subject to the same criminal and collateral issues as marijuana,” the same analysis warned.
Federal and state cannabis laws generally run on separate tracks, according to CRS. Both can apply when they do not directly conflict. The narrower federal definition may also change how states regulate cannabis, so I would check each state’s rules wherever a line is sold.
Choosing a Path for Each Product Line
Each line, from THCA flower to delta-8 products, needs its own answer under the federal hemp ban. The options a company weighs are reformulation, a state-licensed cannabis channel and selling through, each with an open legal question. Before choosing, I would put every product and ingredient through these questions.
- Does it contain a cannabinoid that is not capable of being naturally produced by the plant, which brings in the November 12, 2026 date?
- Does it contain a natural cannabinoid synthesized or manufactured outside the plant?
- What is its total THC, with THCA counted, on a dry weight basis?
- For an intermediate product, what is the combined total of THC and similar-effect cannabinoids? Does any of it reach consumers directly?
- For a final product, how many milligrams of THC and similar-effect cannabinoids does each container hold?
- Which contracts, labels and retail accounts assume the product stays hemp?
Whether a reformulated line stays hemp turns in part on two agency actions the law assigns to FDA and HHS. HHS decides which similar-effect cannabinoids count in both caps. FDA’s natural-production list decides what the November 12 exclusion reaches, so I would test any new formula again whenever either agency publishes.
Whether an excluded hemp product can move into a state-licensed cannabis channel lawfully is open. For marijuana, CRS says, the federal response has largely been to let states run their own laws, even though state-regulated activity may violate the CSA. The April 2026 rule also set a faster DEA registration path for holders of state medical marijuana licenses.
Selling Through, Distribution and Interstate Transport
Whether product on hand can be sold through is open. Who bears the cost of that stock under a supply or distribution agreement is a second open point. We take up both first when planning a sell-through with a company.
For interstate commerce, the 2018 farm bill says nothing in it prohibits interstate commerce in hemp as defined in 7 U.S.C. 1639o. States and tribes also may not block transport through their territory of hemp produced under federal rules. Both are written for hemp as defined, which Section 781 rewrites, so their reach over a product that no longer qualifies stays open.
A fiscal year 2026 funding provision also bars using funds to prohibit the sale or transport of lawfully grown hemp, among other uses. It protects hemp too, so its reach follows the same definition. Whether it carries into the current stopgap funding period is a point we check in each distribution plan.
Frequently Asked Questions About the Federal Hemp Ban
When Does the Hemp Ban Take Effect?
The federal hemp ban reaches products on two dates. Intermediate and final products with cannabinoids the plant cannot naturally produce leave the hemp definition on November 12, 2026. Plant material and extracts face the total THC test on December 11, 2026, the day the intermediate and final product caps also begin.
Is THCA Being Banned?
THCA counts toward total THC and toward both product caps. From December 11, 2026, plant material above 0.3 percent total THC, THCA included, is not hemp. What makes a product final remains open, because the Act does not define the term, CRS notes.
Is Delta-8 Banned?
It is not settled, since the November 12 exclusion turns on an FDA list that CRS reported unpublished as of September 28, 2026. Apart from the Section 781 dates, DEA’s May 4, 2026 rule listing HHC treats chemically converted THC as synthetic under the 2018 definition. Until FDA publishes, a company can record how each cannabinoid it uses was made.
Will the Hemp Ban Affect Dispensaries in States With Legal Cannabis?
It depends on the sale, since marijuana under a state medical license now sits in Schedule III, while adult-use marijuana stays in Schedule I. CRS says the medical marijuana funding rider would cover reclassified products used medically under state law. The rider would not bar prosecution of recreational activity.
Will the Hemp Ban Be Overturned?
Each bill to repeal or rewrite the federal hemp ban remains a proposal until Congress passes it and it is signed. The section above on where the delay effort stands lists each one. It gives the status CRS reported for each on September 28, 2026.
Are Full-Spectrum CBD Products Affected?
Some are. Certain full-spectrum CBD products “will once again be controlled as marijuana under the CSA,” the executive order says, citing THC over the container threshold. For final products, the 0.4 milligram per-container cap in the federal hemp ban applies from December 11, 2026.
