When Will the Hemp Ban Take Effect? Two Dates: Nov 12 and Dec 11, 2026

When does the federal hemp ban take effect?

The federal hemp ban takes effect on two dates, 12 November 2026 and 11 December 2026, and most hemp THC products fall under the second.

Congress wrote the change into section 781 of P.L. 119-37, signed on 12 November 2025. It said the new hemp definition starts 365 days after enactment, which is 12 November 2026. On 2 September 2026, P.L. 119-103, section 2019 pushed most of it back. Until 11 December 2026 the new definition applies only to two kinds of product: intermediate and final hemp products containing cannabinoids that cannot be naturally produced by the cannabis plant.

Status as of 2026-10-26: enacted law, in force on the dates below. The Congressional Research Service (version of 28 September 2026) describes the same split. We found no later law that changes either date.

Stage	Date	What starts	Source
Signed	12 Nov 2025	P.L. 119-37, section 781 enacted	GovInfo
Delay signed	2 Sep 2026	P.L. 119-103, section 2019 limits the 12 Nov start	GovInfo
Stage 1	12 Nov 2026	Products with cannabinoids the plant cannot naturally produce leave the hemp definition	CRS IF13136
Stage 2	11 Dec 2026	Rest of the new definition: total THC, THCA, synthesised natural cannabinoids, 0.4 mg container cap	CRS IF13136

Why do some sites say November 13 or December 11 only?

Sites disagree because they count 365 days differently, or they skipped the September 2026 delay and describe only one of the two stages.

Counting 365 days from 12 November 2025 gives 12 November 2026. Cornell’s copy of the US Code still shows the original “365 days after enactment” note for section 781 and does not mention the delay, so a reader who stops there sees only 12 November. A reader who sees only the delay law sees only 11 December. Both dates are real. They apply to different products.

What is the hemp ban, and what does it change?

The hemp ban is a rewrite of the federal definition of hemp in 7 U.S.C. 1639o, which removes most intoxicating hemp-derived products from it.

Today hemp is cannabis with 0.3 percent or less delta-9 THC by dry weight. That test is what let THCA flower and many gummies and drinks be sold as hemp. The new definition tests total THC, which includes THCA, at the same 0.3 percent for the plant and its derivatives. It then excludes several product types:

• Intermediate or final products with cannabinoids not capable of being naturally produced by the plant.
• Products with cannabinoids that the plant can make but that were synthesised or manufactured outside it.
• Final products with more than 0.4 mg combined total per container of total THC plus other cannabinoids with similar effects, as the Secretary of Health and Human Services determines.
• Intermediate products sold directly to consumers as final products.

Products that leave the hemp definition are treated as marijuana under the Controlled Substances Act, according to the CRS. Industrial hemp (fibre, grain, seed oil, stalk) is carved out of the term “hemp-derived cannabinoid product” and is not the target.

What is legal on each date, by product?

Under federal law, most THC hemp products stay allowed until 11 December 2026, and only products with cannabinoids the plant cannot make fall on 12 November.

This table covers federal law only and is our reading of the statute text, as of 2026-10-26. It is not legal advice. State law can be stricter at any date.

Product	Before 12 Nov 2026	12 Nov to 10 Dec 2026	From 11 Dec 2026
Hemp flower and THCA flower	Federal hemp if delta-9 THC is 0.3% or less	No change	Excluded if a container holds more than 0.4 mg total THC (our reading: retail flower is a final product)
Delta-9 gummies and edibles	Federal hemp if delta-9 THC is 0.3% or less by dry weight	No change	Excluded above 0.4 mg per container
Hemp THC drinks	Same test as gummies	No change	Excluded above 0.4 mg per container
Full-spectrum CBD oil and gummies	Federal hemp	No change	Excluded if total THC exceeds 0.4 mg per container
CBD isolate or broad-spectrum with no measurable THC	Federal hemp	No change	Stays hemp if under 0.4 mg total THC per container
Cannabinoids the plant cannot make naturally	Federal hemp if it passes the old test	Excluded; treated as marijuana	Excluded
Delta-8 or similar made from CBD	Disputed under the old test	Depends on FDA’s lists (see below)	Excluded: made outside the plant, or above the cap
Industrial hemp (fibre, grain, seed oil)	Allowed	Allowed	Allowed
State-licensed marijuana	Not hemp; state-licensed	Not hemp	Not hemp; this definition does not govern it

The delta-8 row is uncertain. Whether a compound counts as “capable of being naturally produced” is meant to be settled by lists that FDA had to publish within 90 days of 12 November 2025. The CRS reports that, as of 28 September 2026, FDA had not published them. If a compound is on FDA’s natural list, it moves with the 11 December group. If it is not, it falls on 12 November.

How does the 0.4 mg per container cap work?

The cap excludes a final hemp product from the hemp definition when one container holds more than 0.4 mg combined total of total THC and similar cannabinoids.

The statute defines a container as the innermost wrapping, packaging or vessel in direct contact with the final product, such as a jar, bottle, bag, packet, can or cartridge. Bulk shipping cartons and outer wrappers do not count. Total THC includes THCA. Here is the arithmetic for four common products, using the 0.4 mg limit:

Product	Calculation	Total THC per container	Over 0.4 mg?
3.5 g jar of flower at the 0.3% plant limit	3,500 mg x 0.003	10.5 mg	Yes, 26 times the cap
3.5 g jar of THCA flower at 20% THCA	3,500 mg x 0.20 = 700 mg THCA, x 0.877 (THC weight per THCA weight)	about 614 mg	Yes, over 1,500 times the cap
Can of drink with 5 mg THC	5 mg	5 mg	Yes, 12.5 times the cap
30 g bottle of CBD oil at 0.3% total THC	30,000 mg x 0.003	90 mg	Yes, 225 times the cap

To stay under the cap, that 30 g bottle would need 0.4 mg / 30,000 mg = 0.0013 percent total THC or less. A single-serving gummy sold in its own sachet is a container on its own, so a 10 mg gummy is 25 times the cap. The 0.877 figure is the weight ratio of THC to THCA (about 314.5 to 358.5), which is why decarboxylation lowers the weight. The flower rows assume the whole jar is a final product, which is the plain reading of the definition. FDA was also told to add detail on the word “container”, and that detail was unpublished as of 28 September 2026.

Will the hemp ban be delayed again?

No further delay is enacted as of 2026-10-26, so the two dates in P.L. 119-103 stand until Congress passes another law.

The first delay was an extension attached to the funding law signed on 2 September 2026. A bill needs to pass both chambers and be signed to move 12 November or 11 December. We did not find one that has done so. Pages written before September 2026 list only 12 November, and some later pages list only 11 December. Check the statute, not a headline, for the date that applies to your product.

What should buyers and sellers check before each date?

Check your state’s hemp law first, then the exact product label, because federal dates only set the minimum change.

1. Read the lab report or label for total THC, including THCA, and note the container size.
2. Compare total THC per container with 0.4 mg.
3. Look for a cannabinoid on the label other than THC and CBD, and check it against FDA’s lists once they are published.
4. Ask whether your state has its own hemp THC rule, such as a ban or a licensed-retailer requirement. For state pages, see our guides.
5. For a sale, an inventory decision or a charge, talk to a lawyer. The sections we read, 781 and 2019, contain no sell-through period for existing stock.
