Section 781 of H.R. 5371, enacted as P.L. 119-37 on 2025-11-12, takes effect on 2026-11-12 and caps finished hemp products at 0.4 milligrams of total THC per container. The sources reviewed through 2026-08-17 contained no FDA definition of "container."

What §781 changes, and which parts a laboratory can answer
The federal hemp redefinition arrived inside a spending bill rather than a farm bill. §781 of P.L. 119-37, the Continuing Appropriations and Extensions Act, 2026 (H.R. 5371), was enacted 2025-11-12 and takes effect one year later, on 2026-11-12. The Congressional Research Service overview of the redefinition is published at congress.gov. It makes three changes:
- The test for what counts as hemp changes. The delta-9-only measurement is replaced by a total THC standard at 0.3% dry weight, inclusive of THCA and delta-8 (P.L. 119-37 §781).
- Finished products get a per-container ceiling. 0.4 milligrams of total THC per container, with the provision describing a container as the innermost packaging in direct contact with the product at retail (P.L. 119-37 §781).
- Origin becomes a test of its own. Cannabinoids not naturally produced by the plant are excluded, as are naturally occurring cannabinoids synthesised outside the plant (P.L. 119-37 §781).
Two of those three can be answered today from evidence a buyer can obtain. Total THC is a laboratory measurement: an accredited lab runs the panel and returns a number. Origin is a manufacturing-record question: either a cannabinoid came out of the plant that way or it was converted, and the process documentation says which. The third cannot be answered at all, because its denominator has no published definition. We keep the wider federal picture on its own maintained page — the three changes, and which two are settled.
The scale of the change is contested territory in itself. The U.S. Hemp Roundtable, an industry advocacy group, estimates that roughly 95% of hemp-derived cannabinoid products currently on the market would fall outside the new standard. That number is the Roundtable's own projection, not a figure published in the statute and not a count taken by any agency — no federal agency has published one — and it carries the weight of an advocacy estimate and no more.
What the provision says, and what remains unresolved
The provision describes the container as the innermost packaging in direct contact with the product at retail (P.L. 119-37 §781; CRS overview at congress.gov). Because the sources reviewed through 2026-08-17 contained no FDA definition, this page does not apply the term to specific packaging configurations or assert later agency activity.
The definition absent from the reviewed record
Section 781 required the Food and Drug Administration to publish the lists of cannabinoids the exclusion covers, and a definition of "container," by a statutory deadline of approximately 2026-02-10. The sources reviewed through 2026-08-17 contained neither an FDA definition nor the anticipated lists. Section 781 of H.R. 5371, enacted as P.L. 119-37 on 2025-11-12, sets 2026-11-12 as the effective date for the hemp provisions.
That is the whole story of this page, and it is unusual enough to state plainly: an industry has until 2026-11-12 to conform finished goods to a numeric ceiling, and the agency charged with saying what that number is measured against has missed its deadline to say it. Nothing about that is speculative — it is a gap in the published record, and it is checkable.
Specific packaging outcomes are not established
Because the sources reviewed through 2026-08-17 contained no FDA definition, this page does not apply "container" to pouches, wrappers, bottles, jars, tins, multipacks, display units, or beverage cans and does not assert later agency activity (P.L. 119-37 §781; CRS IF13136).
Texas already prints the number, without attaching a ceiling to it
There is one place a per-container total THC figure has already been appearing on paperwork. Since 2026-03-31, the Texas consumable-hemp program rules have required a batch certificate of analysis to report the percentage of delta-9 THC, the total delta-9 THC, and the total THC per container (25 TAC §300.301(d)(12)).
That is a disclosure duty and nothing more. The Texas rules contain no per-serving or per-container milligram ceiling anywhere in 25 TAC ch. 300; potency is regulated as a percentage, total delta-9 at or below 0.3% dry weight (25 TAC §300.101(1), §300.302(b)). Any page describing a Texas milligram ceiling is describing something that does not exist.
The useful part for a buyer is that the figure is evidently producible — labs have been reporting it in Texas for months. The unhelpful part is that the state rule uses the same word without resolving the federal question: 25 TAC §300.405 addresses packaging form — tamper-evident, child-resistant, resealable for multi-serving — and nothing in the rule text we reviewed defines the unit for potency purposes. Texas is also a live example of why the federal and state layers cannot be collapsed into one answer: our breakdown of what changed in Texas, and which instrument did it covers a state schedule change running on an entirely separate track from §781.
What a certificate of analysis answers, and what it cannot
A batch certificate of analysis from an ISO/IEC 17025 accredited laboratory reports potency for the sample submitted — normally as a percentage of dry weight and as milligrams per serving or per unit. From 2026-11-12 the federal question is a different one: milligrams per container. Converting between them requires knowing which physical object counts, which is the thing nobody can currently look up.
So a COA that satisfies every other requirement can still leave the per-container figure unresolved, not because the lab did anything wrong but because the arithmetic has an undefined term in it. What a document like that does and does not establish is worth understanding on its own: what a batch COA does and doesn't tell you, and separately, what an evidence file actually contains when a buyer assembles one.
The delay fight does not resolve any of this
On 2026-08-08, the Senate passed H.R. 6500 containing proposed one-month partial-delay language. Two details are routinely reported wrongly. The 90–6 tally was passage of the continuing resolution itself, not a vote on the hemp provision; the provision survived separately on a 61–32 motion to table an amendment offered by Senator Budd. The proposed extension was partial: it did not delay the synthetic-cannabinoid exclusion in §781.
That proposed partial-delay language was not enacted as part of P.L. 119-37. Section 781 of H.R. 5371, enacted as P.L. 119-37 on 2025-11-12, sets 2026-11-12 as the effective date for the hemp provisions. The proposed extension did not define a container.
What a buyer is left holding, and what would close it
The honest inventory is short. Two of the three federal tests are answerable from documents that already exist: an accredited lab report for total THC, and process documentation for cannabinoid origin (P.L. 119-37 §781). The sources reviewed through 2026-08-17 did not supply an FDA definition needed to apply the per-container ceiling to specific packaging. The broader evidence-file questions are maintained in the buyer verification list.
A later FDA container definition or cannabinoid lists required by §781 would require a new verification. If an approved source supplies either, this page will be updated and the change log below will record what moved and when.
Frequently asked questions
What is the 0.4 milligram figure, exactly?
It is a ceiling on total THC in a finished hemp product, measured per container, taking effect 2026-11-12 under §781 of P.L. 119-37. It sits alongside the separate 0.3% dry-weight total THC test that determines whether material qualifies as hemp at all.
Does it apply per serving or per package?
Per container, as the statute is written (P.L. 119-37 §781). A multi-serving package does not receive an allowance per serving. Which physical layer counts as the container is the unresolved part.
Has FDA defined "container"?
The sources reviewed through 2026-08-17 contained neither the FDA definition nor the anticipated cannabinoid lists after the approximate 2026-02-10 deadline under §781. This article does not assert later agency activity.
Has the November 2026 date been delayed?
Section 781 of H.R. 5371, enacted as P.L. 119-37 on 2025-11-12, sets 2026-11-12 as the effective date for the hemp provisions. On 2026-08-08, the Senate passed H.R. 6500 containing proposed one-month partial-delay language; that language was not enacted as part of P.L. 119-37.
Does Texas apply the same per-container figure?
No. Texas regulates potency as a percentage, total delta-9 at or below 0.3% dry weight (25 TAC §300.101(1)), and requires total THC per container to be reported on the batch COA as a disclosure (25 TAC §300.301(d)(12)). No milligram ceiling appears anywhere in 25 TAC ch. 300.
Change log
- 2026-08-19 — date-gate de-temporalization. Replaced live legislative and FDA-publication status wording with the enacted 2026-11-12 effective date, the dated 2026-08-08 Senate action, and the agency record reviewed through 2026-08-17; no later outcome is asserted.
- 2026-08-17 — specific packaging interpretations removed. The page states that the sources reviewed through that date contained no FDA definition and does not apply "container" to any packaging configuration.
- 2026-08-16 — first version, written and source-verified. Checked against §781 of P.L. 119-37 as enacted 2025-11-12, the Congressional Research Service overview of the hemp redefinition, the Texas consumable-hemp program rules at 25 TAC ch. 300, and the Senate action of 2026-08-08 on H.R. 6500. No published FDA container definition or cannabinoid list was found at the time of writing.

What we checked for this page: §781 of P.L. 119-37 (Continuing Appropriations and Extensions Act, 2026 / H.R. 5371), enacted 2025-11-12; the Congressional Research Service overview of the federal hemp redefinition published at congress.gov; the Texas Department of State Health Services consumable-hemp program rules at 25 TAC ch. 300, in force since 2026-03-31; and the Senate continuing-resolution action of 2026-08-08. Where the published record is silent — the container definition and the cannabinoid lists — we have said so rather than filled the gap. Published by The FireBar Labs Team.
