Federal hemp redefinition: what changes on 12 November and on 11 December 2026
Most of the federal hemp redefinition now takes effect on 11 December 2026, not 12 November. H.R. 6500, signed on 2 September 2026, delayed the total-THC standard, the 0.4 milligram per-container cap and the exclusion for cannabinoids made outside the plant by 30 days. One part was not delayed: cannabinoids that are not capable of being naturally produced by a Cannabis sativa L. plant lose hemp status on 12 November 2026.
| Product or rule | Today | From 12 November 2026 | From 11 December 2026 |
|---|---|---|---|
| Cannabinoids not capable of being naturally produced by the cannabis plant | Sold in many markets under the 2018 hemp definition | Excluded from hemp | Excluded from hemp |
| Naturally occurring cannabinoids synthesized or manufactured outside the plant | Sold in many markets under the 2018 hemp definition | No change yet | Excluded from hemp, at any concentration |
| Hemp plants and flower | Delta-9 THC at or below 0.3% on a dry-weight basis | No change yet | Total THC, counting THCA, at or below 0.3% on a dry-weight basis |
| Finished products: gummies, drinks, tinctures, vapes | No federal per-container limit | No change yet | More than 0.4 mg of total THC and similar cannabinoids per container is not hemp |
| Anything that falls outside hemp | Not applicable | Treated as marijuana under the Controlled Substances Act | Treated as marijuana under the Controlled Substances Act |
The change comes from P.L. 119-37, the appropriations law enacted on 12 November 2025. It rewrote the federal definition of hemp and gave the market a year to adjust, which made 12 November 2026 the original effective date.
H.R. 6500, the Continuing Appropriations and Extensions Act, 2027, passed the House on 1 September 2026 and was signed the next day. It moved the effective date of most of the new definition to 11 December 2026. It repealed none of it.
Under the new definition, hemp is measured by total THC, which counts THCA as well as delta-9 THC, at 0.3% or less on a dry-weight basis. A finished product that holds more than 0.4 milligrams per container of total THC, combined with any other cannabinoids that have or are marketed as having similar effects, is not hemp. Neither are cannabinoids synthesized or manufactured outside the plant, whatever their concentration.
Which compounds count as not capable of being naturally produced by the plant, and how a container is measured, turn on lists and guidance the FDA had not published as of 19 October 2026. Until they appear, a business deciding which date reaches a product is working from the statute alone.
11 December 2026 is also the next federal funding deadline, so Congress could move the date again. Bills to replace the new definition with a regulatory framework, to delay it further or to repeal it have been introduced; as of 19 October 2026 none had advanced past committee.
What changed
The effective date for most of the new federal hemp definition moved from 12 November 2026 to 11 December 2026. That covers the total-THC standard, the 0.4 milligram per-container cap on finished products, and the exclusion for cannabinoids synthesized or manufactured outside the plant.
What did not change
The definition itself. H.R. 6500 delayed it; it did not repeal or soften it. The exclusion for cannabinoids that are not capable of being naturally produced by a Cannabis sativa L. plant still takes effect on 12 November 2026, and state hemp laws, including North Carolina's, run on their own timelines.
Who this reaches
Hemp and CBD brands, manufacturers, distributors and retailers selling intoxicating hemp products, and anyone holding inventory or supply contracts priced on the old definition. Before each date, sort inventory by which rule reaches it, require certificates of analysis that report total THC rather than delta-9 alone, and check supply and distribution contracts for change-in-law and termination terms.
Common questions
Is the federal hemp ban delayed?
Mostly. H.R. 6500, signed on 2 September 2026, moved most of the new hemp definition from 12 November to 11 December 2026. Cannabinoids that are not capable of being naturally produced by the cannabis plant still lose hemp status on 12 November.
Is THCA flower still hemp after 11 December 2026?
Under federal law, not if its total THC, counting THCA, is above 0.3% on a dry-weight basis, and most THCA flower sold today is above that line. State law can be stricter and can apply sooner.
What does 0.4 milligrams per container mean?
It is a cap on the whole container, not on a serving. A finished product holding more than 0.4 milligrams of total THC, combined with other cannabinoids that have or are marketed as having similar effects, is not hemp under the new definition.
Does the 12 November date reach delta-8 products?
It depends on how the product's cannabinoid is classified. Cannabinoids the plant cannot naturally produce are reached on 12 November; naturally occurring cannabinoids converted outside the plant are reached on 11 December. Commentators disagree on where some products fall and the FDA has not published its lists, so the earlier date is the cautious one to plan around.
Can Congress change the date again?
Yes. 11 December 2026 is also the federal funding deadline, and bills to delay, replace or repeal the new definition have been introduced. As of 19 October 2026 none had advanced past committee, so the December date should be treated as real.
What about North Carolina?
North Carolina's House Bill 328 would cap finished hemp products at 0.4 milligrams of total THC per container, count THCA toward total THC, and bar sales to anyone under 21. The Senate has adopted the conference report; the House has not voted and in August put the vote off until November. The federal definition applies in North Carolina either way.
