What is Section 781: a cannabis seed on a gavel block beside federal statutes

What is Section 781? It is the part of a 2025 federal spending law that rewrites the legal definition of hemp. It matters to anyone who collects cannabis seeds, because the new definition treats seeds from high-THC plants differently than the 2018 Farm Bill did.

I’m James Bean, and I have run Seeds Here Now since 2010. This is my honest, plain-English answer to what Section 781 is, what it changes, what it does not change, and where things stand.

What Is Section 781? The Short Answer

Section 781 is Division B, Section 781 of H.R. 5371, the FY2026 Agriculture appropriations law (P.L. 119-37). It amends the federal definition of hemp in 7 U.S.C. 1639o. Products that fall outside the new definition are no longer hemp under federal law and are instead treated as marijuana under the Controlled Substances Act.

For seed collectors, the key line is the seed exclusion: viable seeds from a cannabis plant that is above 0.3% total THC, including THCA, are excluded from hemp. Under the 2018 framework, the DEA said in 2022 that seeds with no more than 0.3% delta-9 THC fit the hemp definition. Section 781 changes that picture.

The Hemp Definition: Before vs. After Section 781

The simplest way to answer what Section 781 is: compare the two definitions side by side.

Point	2018 Farm Bill definition	Section 781 definition
THC measure	Delta-9 THC, 0.3% or less (dry weight)	Total THC including THCA, 0.3% or less (dry weight)
Seeds	Seeds included in hemp	Viable seeds from plants above the total THC limit excluded
Synthetic cannabinoids	Not addressed directly	Excluded from hemp
Finished products	No per-container limit	0.4 mg total THC (and similar cannabinoids) per container
Industrial hemp	Not separately defined	Explicitly included (fiber, grain, seed oil and similar uses)

Where Section 781 Came From

After the 2018 Farm Bill, a large market grew up around intoxicating hemp-derived products such as delta-8 THC gummies and drinks. Lawmakers in both parties raised concerns about those products, and the House and Senate debated changes to the hemp definition in the FY2026 Agriculture appropriations bills. The final law used a total THC standard and added exclusions aimed at intoxicating products.

Seeds were caught up in that rewrite. Most seeds sold by cannabis seed banks come from plants above 0.3% total THC, so the seed exclusion is the part of Section 781 that matters most to collectors.

Where Section 781 Stands Now

Section 781 was enacted in November 2025 as part of the FY2026 Agriculture appropriations law (H.R. 5371, P.L. 119-37). In September 2026, Congress passed a continuing resolution (P.L. 119-103) that revisited parts of the new definition. Other bills would delay the change, repeal it, raise the THC limit or defer to state definitions. None of those has become law as of this update.

We are following official guidance closely and will update this page as it develops. Nothing here is a promise about future law.

What Section 781 Covers

Hemp is measured by total THC, including THCA, rather than delta-9 THC alone.
Viable seeds from plants above 0.3% total THC are excluded from hemp.
Synthetic cannabinoids, and cannabinoids made outside the plant, are excluded.
Intermediate products above 0.3% combined total THC and similar cannabinoids are excluded.
Final products above 0.4 mg combined total THC and similar cannabinoids per container are excluded.
The FDA must publish lists of naturally occurring cannabinoids and THC-class cannabinoids; as of the latest CRS update it had not done so.

Those finished-product limits are why many people call Section 781 a hemp THC ban.

What Section 781 Does NOT Do

It does not change state cannabis laws. State adult-use and medical programs keep their own rules.
It does not repeal the hemp program. Industrial hemp for fiber, grain and seed oil is explicitly included.
It does not change the 21+ rule we apply to every order.
It is not the last word. Congress has already changed its timing once and is debating more bills.

Live clones are a different product. As we understand it, the seed change is aimed at viable seeds, and live clones are not affected by the seed change. Every plant product still has to meet federal hemp THC limits, and state law still applies. See our cannabis clones by state hub for state clone laws.
