Federal Hemp Ban Takes Effect November 12 With FDA Guidance Unpublished and Repeal Bills Stalled

The federal redefinition of hemp takes effect November 12, 2026, and the guidance meant to clarify its scope has not appeared. Most hemp-derived cannabinoid products, from THCA flower to delta-8 edibles, will fall outside the legal definition of hemp on that date unless Congress intervenes. No repeal or delay bill has advanced.

Congress rewrote the federal definition of hemp in Section 781 of the Continuing Appropriations and Extensions Act, 2026, signed November 12, 2025. The provision replaces the 2018 Farm Bill's delta-9-only test with a total THC standard that counts THCA toward the 0.3% threshold. It caps finished hemp cannabinoid products at 0.4 milligrams of total THC per container and excludes cannabinoids synthesized outside the plant. The changes take effect November 12, 2026, and products that fall outside the new definition become subject to Schedule I enforcement under the Controlled Substances Act on that date.

The law directed the FDA to publish lists of covered cannabinoids and a definition of the term container by February 10, 2026. The Congressional Research Service reports the lists had not been published as of May 2026. The FDA submitted a CBD compliance and enforcement policy to the Office of Management and Budget in March.

Relief efforts have stalled in Congress. H.R. 6209 would strike Section 781, and H.R. 7024 would move the effective date to November 2028, with a Senate companion from Senators Klobuchar, Paul, and Merkley. Neither has advanced out of committee. The House passed the 2026 Farm Bill on April 30 with the total THC standard intact, after delay amendments were ruled not germane or withdrawn without votes.

The redefinition reaches THCA flower, delta-8 and other converted cannabinoids, and most full-spectrum CBD products. The U.S. Hemp Roundtable estimates the new definition excludes more than 90% of current hemp cannabinoid products. Industrial hemp for fiber and grain, and CBD isolate products under the 0.4 milligram container cap, remain within the definition. The deadline arrives whether or not the FDA publishes its guidance, and state hemp laws, several of which already apply total THC standards, continue to operate alongside the federal change. Products outside the definition become subject to federal Controlled Substances Act enforcement on November 12, 2026.
