The 2026 federal hemp rule, explained in plain language

The federal definition of hemp is one paragraph of the Agricultural Marketing Act of 1946, codified at 7 U.S.C. 1639o. For seven years it said 0.3% delta-9 THC on a dry weight basis and nothing else. In November 2025 Congress rewrote it, and in September 2026 Congress split the rewrite into two effective dates. This page walks through the text, the two dates, what each product type faces, and the bills that could still change the outcome.

What did section 781 of P.L. 119-37 change?

The first change is the measuring stick. The old definition counted only delta-9 THC. The new subparagraph (A) counts "total tetrahydrocannabinols concentration (including tetrahydrocannabinolic acid)" at not more than 0.3% on a dry weight basis. THCa is the acid form that converts to delta-9 THC when heated, and flower sold as "THCa hemp" is typically 15% to 25% THCa by weight, so the total standard removes that product from the definition the moment it takes effect.

The second change is a product-level cap. Subparagraph (C)(iv) excludes any final hemp-derived cannabinoid product containing "greater than 0.4 milligrams combined total per container" of THC and cannabinoids with similar effects (Cornell LII). This is a milligram figure, not a percentage, and it applies per container rather than per serving.

The third and fourth changes are exclusions by origin. Subparagraph (C)(ii)(I) excludes products with cannabinoids "not capable of being naturally produced by a Cannabis sativa L. plant". Subparagraph (C)(ii)(II)(bb) excludes cannabinoids that "were synthesized or manufactured outside the plant", even when the plant could make them. And subparagraph (C)(iii) excludes "any intermediate hemp-derived cannabinoid products which are marketed or sold as a final product", which is the clause that separates bulk distillate from a bottle on a shelf. Section 781(3) also ordered FDA to publish lists of the covered cannabinoids and "additional information and specificity about the term 'container'" within 90 days of enactment.

What did section 2019 of P.L. 119-103 delay?

The drafting matters. Congress did not strike the 365-day clock, so the amendments still "take effect" on November 12, 2026. Instead it narrowed which products the amendments reach for 29 days. The two paragraphs it named are the clauses about cannabinoids the plant cannot naturally produce: (1)(C)(ii)(I) for intermediate products and (1)(C)(iv)(I) for final products. Every other clause, including the total THC standard, the 0.4 mg cap, the "synthesized or manufactured outside the plant" exclusion and the intermediates-as-final-products exclusion, is held back until December 11.

Vicente LLP's October 13, 2026 analysis reads the section the same way: "the ban on synthetic cannabinoids in hemp products still takes effect November 12, 2026" while the total THC standard and per-container cap move to December 11 (Vicente LLP). Foley Hoag called the extension "a short window" and noted that Congress must act again before December 11 for anything further (Foley Hoag). December 11 is also the day the continuing resolution itself expires, which is why the next funding bill is the most likely vehicle for any change.

What happens on November 12, 2026?

The practical question is where delta-8 THC and THCP fall. Both occur in the plant in trace amounts, so a literal reading puts them under the "synthesized or manufactured outside the plant" clause that waits until December 11, not under the November 12 clause. This site does not rely on that reading. Nearly all commercial delta-8 and THCP is made by converting CBD with reagents, FDA has not published the list that would settle the question, and a four-week gap is not worth an enforcement dispute. The store removed every converted cannabinoid from its catalog before November 12 and applies the same cutoff to delta-8, THCP, HHC, THC-O and THC-JD.

What happens on December 11, 2026?

Oklahoma's agriculture department summarized the same 2 limits in its January 16, 2026 letter, a useful plain-language restatement from a regulator. It states that any intermediate product "must contain no more than 0.3% Total THC on a dry-weight basis after decarboxylation", that any final product "must contain no more than 0.4 milligrams of Total THC per container", and that "Containers are defined as the retail packaging (e.g., jars, bottles, cartridges)" (ODAFF). The letter predates the September delay, so it gives November 12 for both; the December 11 date now governs the second limit.

What "stops being hemp" means in practice is the hard part. A product outside the hemp definition is not automatically illegal under state law, but it loses the federal exemption that made interstate shipment lawful, and carriers and payment processors key their policies to that exemption. Ohio's SB 56 shows the state-level version of the same logic: products outside the narrowed definition are "considered marijuana and sold exclusively in marijuana dispensaries" (Ohio LSC).

What is the innermost container?

For a tincture the container is the bottle. A 30 mL bottle is one container no matter how many droppers it holds, so a product with 0.5 mg of THC in the whole bottle fails, and a product with 0.01 mg per dropper and 30 droppers also fails. For gummies the container is the jar or pouch, and a jar of 30 gummies at 0.02 mg THC each holds 0.6 mg and fails. For single-serve packaging the math flips: a blister cell or a single sachet in direct contact with the product is its own container, which is why some manufacturers are moving to unit-dose formats.

Ohio's statute, which copied the federal structure, defines its container as the innermost packaging in direct contact with the product, such as a jar, bottle, can or cartridge, and excludes bulk shipping containers and outer wrappers (Ohio LSC). New Jersey adopted the same 0.4 mg per container threshold as of April 13, 2026, with beverages given a transition through November 13, 2026 (NJ CRC). The federal FDA guidance that would settle edge cases, such as a shrink-wrapped two-pack, has not been published.

Where are the FDA cannabinoid lists?

The missing lists leave three open questions. First, whether CBN made by oxidizing CBD, or CBC made by conversion, counts as "synthesized or manufactured outside the plant" when the plant can also make it; the statutory text says yes if the molecule was made outside the plant, which is why this store asks every CBN supplier for a process attestation. Second, which minor cannabinoids count toward the 0.4 mg total; the text says THC "and cannabinoids with similar effects", and the list was supposed to name them. Third, how a multi-pack is counted.

Without the lists, the conservative reading controls every decision on this site: count every THC isomer and THCa toward the 0.4 mg figure, assume any converted cannabinoid is outside the definition, and count the innermost sealed unit as the container. The Congressional Research Service has tracked the implementation questions in its Insight series (IN12620); the page was not retrievable for this review, so its current contents are marked TODO: verify.

What does the rule mean for isolate and broad-spectrum products?

That is a higher bar than most COAs clear. A common potency method reports non-detect at a limit of quantitation of 0.01% to 0.05% by weight. At 0.01%, a 28 g jar of gummies could hold up to 2.8 mg of THC and still read "ND", which is 7 times the cap. The store therefore asks suppliers for total THC reported in milligrams per container, or for an LOQ around 10 parts per million on 30 mL formats, and marks any SKU that cannot show it as a December 11 review item.

What does the rule mean for full-spectrum products?

Even a "low THC" full-spectrum product at 0.1% THC by weight fails: 0.1% of a 30 g bottle is 30 mg. Only products with THC removed to the parts-per-million level pass, and at that point the product is broad-spectrum. That is why the state table isolates full-spectrum in its own lane, why every full-spectrum row carries the December 11 note, and why the store keeps the lane in a separate collection with its own sitemap that can be removed in one deploy.

Several states already enforce caps below the full-spectrum range, which is why the lane is excluded in 25 jurisdictions on the reviewed date: Ohio at 0.4 mg per container since March 20, 2026, New Jersey at 0.4 mg since April 13, 2026, Maryland at 2.5 mg per package, Virginia at 2 mg per package since August 15, 2026, Hawaii, Rhode Island, Iowa, New York and Montana with their own per-serving and per-package limits. Those rows do not change on December 11; the remaining 26 do.

What does the rule mean for THCa flower and THC drinks?

A 5 mg THC seltzer is 12.5 times the cap in one can, and a 10 mg can is 25 times. The only drink that survives is one with less than 0.4 mg of total THC in the container, which is not an intoxicating product. State law has already closed most of this lane: on the reviewed date, lane B is an exclude in 42 of 51 jurisdictions, with total THC states like Michigan, South Dakota, Wyoming, Oklahoma and Florida on one side and dispensary-only states like Arizona, Colorado, Maryland and Ohio on the other. After December 11 the remaining 9 close as well.

Which bills could change the outcome?

The framework bills are different in kind. H.R. 9830, the Lawful Hemp Protection Act, introduced July 22, 2026 by Rep. Barr with Rep. Craig as lead cosponsor, would create separate categories for industrial hemp and consumable hemp products, set a 1% total THC limit on a dry weight basis, and prohibit synthetic cannabinoids; it was referred to the Ways and Means, Energy and Commerce, Agriculture, and Transportation and Infrastructure committees (GovInfo, H.R. 9830). Vicente names it and Rep. Van Duyne's Beverage Regulatory Parity Act as the frontrunners, both "pending in committee" (Vicente LLP). Foley Hoag adds a Comer draft and an expected Senate companion (Foley Hoag). H.R. 10079, named in the underlying research as a delay bill, could not be located in the search record and is marked TODO: verify bill status.

The House adjourned for the election with a lame-duck session and a December funding deadline as the only vehicles, so a second extension inside the next continuing resolution is the most plausible change.

How do state rules interact with the federal change?

Some states are moving with the federal text and some against it. Illinois fixed November 12, 2026 as its date regardless of the federal delay; Missouri tied its date to the federal effective date; Rhode Island will adopt the federal definition on December 11 with no transition period; Minnesota says it will keep regulating hemp-derived products under its own statute whatever happens federally, though products outside the federal definition would lose lawful interstate commerce (Vicente LLP). Ohio and New Jersey already enforce a 0.4 mg per container threshold.

For a buyer the rule of thumb is simple. Non-detect THC products follow the state table's A1 row and are unaffected by December 11 if the COA proves it. Anything with measurable THC follows the stricter of the state row and the federal date. And anything intoxicating is, on this site, already gone. The state table is republished on both federal dates with a new reviewed date so the two layers never drift apart.
