The first part of the new federal hemp definition takes effect on Thursday, November 12, 2026. It targets a narrower category: intermediate and finished hemp-derived cannabinoid products containing cannabinoids that the cannabis plant cannot naturally produce. It does not, by itself, bring every hemp-derived THC product under the new rules. The broader changes, including the 0.4 milligram per container limit, follow on December 11.
With less than two weeks to go, this article explains what changes on November 12, what does not change yet, why some questions remain open, and practical steps North Carolina hemp businesses can take now. It is for general information and is not legal advice.
What Changes on November 12
Congress rewrote the federal definition of hemp in November 2025. A continuing resolution passed on September 2, 2026, delayed most of the new definition to December 11, but kept one provision on the original November 12 date, according to a September 28 Congressional Research Service update.
That provision excludes intermediate and final hemp-derived cannabinoid products that contain cannabinoids "not capable of being naturally produced" by the cannabis plant. According to a CRS legal analysis dated October 28, starting November 12, products covered by this exclusion will no longer qualify as hemp and will be treated as controlled substances to the extent they fall within the Controlled Substances Act's definitions of marijuana or THC.
In practical terms, this applies even if the product was made from hemp.
Which Products Are Likely Affected
The clearest example is THC-O. The October 28 CRS analysis identifies THC-O as a cannabinoid that does not occur naturally in cannabis.
THC-O also has a North Carolina connection. In a 2024 case brought by a North Carolina worker, Anderson v. Diamondback Investment Group, the federal Fourth Circuit Court of Appeals, which covers North Carolina, declined to treat the DEA's view that THC-O is illegal as binding, according to a summary by the law firm Foley Hoag. The decision did not establish that all THC-O products were lawful. It addressed the legal weight of the DEA's position in that particular case. The new federal law now creates an explicit exclusion that addresses the question directly for covered products.
Shop owners should check ingredient lists and lab reports for any cannabinoid that may not occur naturally in the plant. We explained how these lab-made and converted cannabinoids are discussed in our explainer on semi-synthetic cannabinoids.
What Does Not Change Until December 11
According to CRS, the other parts of the new hemp definition do not take effect until December 11, 2026. These include:
-
Excluding products containing cannabinoids that can occur naturally in the cannabis plant but were synthesized or manufactured outside the plant
-
A total THC concentration limit of 0.3 percent by dry weight, including THCA, under the amended hemp definition
-
Excluding intermediate hemp-derived cannabinoid products containing more than 0.3 percent combined total THC and other cannabinoids with similar effects
-
Excluding final hemp-derived cannabinoid products containing more than 0.4 milligrams combined per container of total THC and other cannabinoids with similar effects
This difference matters. A product made with a cannabinoid that does exist in the plant, but was produced through a lab process, is in the December 11 group, not the November 12 group. We explained both dates in our guide to what changes on November 12 and December 11.
Why Some Questions Are Still Open
The 2025 law required the FDA to publish lists that would help businesses sort products into these groups, including a list of cannabinoids known to be capable of being naturally produced by the plant, and guidance on the meaning of "container." The FDA had not published any of these items as of October 28, according to the CRS legal analysis.
The absence of the FDA's lists does not, by itself, postpone the statutory effective date. However, it may make it more difficult to classify some individual cannabinoids. That is why documentation from suppliers and lab testing matter more than usual right now.
Several federal bills, including H.R. 7024, H.R. 7010 and S. 3686, would delay the new definition for two more years. In its October 28 analysis, CRS identified no enacted legislation providing a further delay. None of these proposals has changed the November 12 or December 11 dates, so businesses should continue planning around the dates in current law unless Congress acts.
Where North Carolina Law Stands
North Carolina has not passed its own hemp regulation bill. HB 328, the bill to regulate hemp-derived consumables, has had no new action since July 30, when its conference report was re-referred to the House Rules, Calendar, and Operations Committee. The bill record shows no action on it during the House's October 26 to 28 session.
The conference report was written so that its new state definition of hemp would take effect on November 12, matching the federal date. Because the House has not voted on it, that provision is not state law. Under the legislature's adjournment resolution, the General Assembly is scheduled to return on November 16, four days after the federal date.
North Carolina businesses have been watching the federal dates closely. Local coverage, including the Lincoln Herald, has reported that some products could come off shelves in November and December, and that state rules cannot override the federal definition.
The Governor's Advisory Council on Cannabis also has a meeting on November 12, when its Public Safety Subcommittee is scheduled to meet online from 1 to 3 p.m., according to the council's website.
What North Carolina Hemp Shops Can Do Before November 12
-
Review your shelf and back stock. Check labels and certificates of analysis for any cannabinoid that may not occur naturally in the cannabis plant, such as THC-O.
-
Ask suppliers in writing. Request a list of every cannabinoid in each product, current lab reports, a statement on whether each cannabinoid occurs naturally in the plant and supporting technical documentation.
-
Set aside products you cannot confidently classify. Consider pausing sales or reorders while you seek clarification from your supplier or legal counsel. This is a precautionary business step, not a separate requirement stated in the federal law.
-
Keep records. Save lab reports, invoices and supplier messages in case questions come up later.
-
Start planning for December 11. Compare your inventory with the 0.4 milligram per container limit and check shipping changes, such as UPS's new hemp shipping terms.
-
Get legal advice on your specific products.
Keep in mind that a supplier statement or certificate of analysis is useful documentation, but it does not by itself prove that a product complies with federal law.
Business owners who want to share how these dates affect them can also contact their state representative, as explained in our guide on how to contact your representative about HB 328, or submit a comment to the cannabis council through its online comment form.
Frequently Asked Questions
Q. Is hemp THC illegal on November 12?
Not all of it. On November 12, the federal change applies to intermediate and finished hemp-derived products containing cannabinoids that the cannabis plant cannot naturally produce. Other changes, including the exclusion of final products containing more than 0.4 milligrams combined per container of total THC and similar-effect cannabinoids, take effect on December 11.
Q. Is THC-O legal after November 12?
The Congressional Research Service identifies THC-O as a cannabinoid that does not occur naturally in cannabis. Starting November 12, products containing cannabinoids that the plant is not capable of naturally producing no longer qualify as federal hemp.
Q. Has the FDA published the list of natural cannabinoids?
Not as of October 28, 2026, according to a Congressional Research Service legal analysis. The FDA had not published any of the required lists or the guidance on "container."
Q. Does North Carolina have its own hemp law taking effect November 12?
No. HB 328 includes a November 12 effective date for its hemp definition, but the House has not voted on the conference report, so it is not law.
Q. When does the 0.4 milligram per container limit start?
Under current federal law, final hemp-derived cannabinoid products with more than 0.4 milligrams combined per container of total THC and similar cannabinoids are excluded from the definition of hemp starting December 11, 2026.
