Federal Hemp Law Changes 2026 — Everything That's Changing
Updated March 2026 · H.R. 5371 Analysis
Congress rewrote the federal definition of hemp on November 12, 2025, replacing the Delta-9-only THC threshold from the 2018 Farm Bill with a total THC standard and a 0.4 milligram per container cap on finished products. The changes take effect in November 2026.
Section 781 of H.R. 5371 — the Continuing Appropriations and Extensions Act, 2026 — is the most significant federal action on hemp since the 2018 Farm Bill. It closes the so-called “Farm Bill loophole” that allowed intoxicating hemp products to flood the market by measuring only Delta-9 THC while ignoring Delta-8, Delta-10, THCA, and dozens of other psychoactive cannabinoids.
The Old Definition vs. The New Definition
2018 Farm Bill (expiring November 2026)
Hemp = Cannabis sativa L. with a Delta-9 THC concentration of no more than 0.3% by dry weight.
H.R. 5371 (effective November 2026)
Hemp = Cannabis sativa L. with a total tetrahydrocannabinol concentration (including THCA) of no more than 0.3% on a dry weight basis.
The word “total” does the heavy lifting. Under the old definition, a product could contain 50mg of Delta-8 THC, 30mg of THCA, and 15mg of Delta-10 THC per serving — and as long as the Delta-9 THC was under 0.3%, it qualified as “hemp.” Under the new definition, all those compounds count.
The 0.4mg Container Cap
Beyond the plant-level definition, H.R. 5371 introduces a finished product restriction. Any “final hemp-derived cannabinoid product” with more than 0.4 milligrams per container of total THC and similar-effect cannabinoids is excluded from the definition of hemp.
| Product | Typical THC Content | Federal Cap | Over Limit By |
|---|---|---|---|
| Delta-8 gummy (10-pack, 25mg each) | 250mg per container | 0.4mg | 625x |
| THCA flower (3.5g, 20% THCA) | ~700mg THCA per container | 0.4mg | 1,750x |
| Hemp-derived THC beverage (12oz) | 5–10mg per can | 0.4mg | 12–25x |
| Full-spectrum CBD tincture (30ml, 0.3% THC) | ~90mg per bottle | 0.4mg | 225x |
| CBD isolate gummy (zero THC) | 0mg | 0.4mg | Compliant ✓ |
What “Container” Means
H.R. 5371 defines “container” as “the innermost packaging that encloses the final product for retail sale.” For a bag of gummies, that's the bag. For a bottle of tincture, that's the bottle. For a multi-pack of beverages, it's each individual can — not the outer cardboard carrier.
This definition matters for brands considering reformulation. A single gummy with 0.3mg of total THC in individual packaging would technically comply. A 10-pack bag of those same gummies at 3mg total would not.
Synthetic and Semi-Synthetic Cannabinoid Exclusions
The law also excludes products containing cannabinoids that are “not capable of being naturally produced by Cannabis sativa L.” This targets the semi-synthetic production methods used to manufacture most commercial Delta-8 THC — which is typically converted from CBD through chemical isomerization, not extracted directly from the plant.
Whether Delta-8 THC counts as “naturally occurring” or “manufactured” remains legally ambiguous. The FDA's forthcoming cannabinoid classification lists will likely settle this question.
The FDA's Cannabinoid Lists
Within 90 days of the law's November 12, 2025 enactment, the FDA must publish four lists:
- Cannabinoids naturally produced by Cannabis sativa L.
- THC-class cannabinoids — Delta-8, Delta-9, Delta-10, THCV, etc.
- Cannabinoids with similar effects to THC-class cannabinoids — could include HHC, THCP, and others
- Further definition of “container” — clarifying edge cases in packaging
As of March 2026, these lists have not been finalized. The FDA's timeline has slipped, which creates uncertainty for brands trying to reformulate before the November 2026 effective date.
How States Are Responding
Aligning with federal changes early
New Jersey passed a bill matching the new federal definitions ahead of the November 2026 deadline, with inventory liquidation deadlines for retailers. Connecticut and Louisiana updated their existing hemp product regulations to reference total THC.
Pushing for continued access
Texas Governor Greg Abbott vetoed a strict hemp ban, issuing instead an executive order with age restrictions and labeling requirements. Florida's governor similarly vetoed a hemp THC ban.
Waiting for FDA guidance
Many states are holding off on new legislation until the FDA publishes its cannabinoid classification lists. Without knowing which compounds count toward the cap, state legislators can't write precise rules.

Frequently Asked Questions
Does this law ban CBD?
No. Hemp-derived CBD products with total THC under 0.3% (plant level) and under 0.4mg per container (finished product level) remain federally legal. CBD isolate products with zero THC are entirely unaffected. The law targets intoxicating products, not cannabidiol itself.
Can states still allow Delta-8 and THCA after November 2026?
States retain authority to regulate hemp products within their borders. A state could create a licensed hemp product program allowing sales of products that exceed federal thresholds — similar to how 24 states allow recreational marijuana sales despite federal prohibition.
What should hemp brands do right now?
Three steps: (1) Audit product lines against the 0.4mg total THC container cap. (2) Begin reformulation R&D for products that exceed the cap. (3) Track state-by-state regulatory developments — our news section covers these within 24–48 hours of announcement.
