Federal: total THC incl. THCA, 0.4 mg per container, converted delta-8
H.R. 6500 (signed Sep 2, 2026) provides that until Dec 11, 2026 the §781 amendments apply only to non-natural-cannabinoid products. So from Dec 11, 2026 the rest applies: hemp means total THC including THCA at 0.3% or less by dry weight; final products above 0.4 mg combined total THC per container are excluded; cannabinoids the plant can make but that were synthesized or manufactured outside it (commercial delta-8 converted from CBD) are excluded. DEA separately holds that chemically converted THCs are already Schedule I (91 FR 23913).

Federal funding bill expires
The Continuing Appropriations and Extensions Act, 2027 funds the government through Dec 11, 2026, the same day the rest of the hemp redefinition takes effect. The next spending bill is the most likely vehicle for any further change to the hemp dates; the OMB letter of Jun 24, 2026 asked Congress for 'at minimum, an extension' of §781's implementation.

Federal: cannabinoids the plant cannot make leave the hemp definition
From Nov 12, 2026 (365 days after enactment) intermediate and final hemp-derived cannabinoid products containing cannabinoids 'not capable of being naturally produced by a Cannabis sativa L. plant' (subclauses (1)(C)(ii)(I) and (iv)(I)) are no longer hemp and fall under the Controlled Substances Act. Until Dec 11, 2026 this is the only part of §781 that applies. On Oct 8, 2026 we found no FDA list that names which cannabinoids qualify (a dated search; see the row on FDA's lists).
