A Serving Is Not a Container

Most of the wrong answers we write up are published by people with nothing at stake in them. This one is different. Three hemp brands told their own subscribers what the new federal limit is, gave the same number in the same unit within eleven days of each other, cited nothing, and are changing what ships in December on the strength of it.

We read all three pages first-party this morning.

The same sentence, three times

Medterra's page is dated September 3. It says the threshold is "currently anticipated around 3mg of total THC per serving" starting December 11, 2026.

five's page is dated September 14. It says products are "expected to fall under a new, lower THC threshold — currently landing around 3mg of total THC per serving."

Vena's page is dated September 14. It says "currently anticipated around 3mg of total THC per serving," and that "the current federal timeline points to December 11, 2026."

Three companies. Two different weeks. One figure, one unit, one date. Not one of the three names a public law number, a section, or an agency. Two of the three do not mention November 12, 2026 anywhere.

And these are not explainers. They are subscription notices. Medterra's says 5 mg subscriptions convert automatically to 2.5 mg from the December shipment. five's discontinues its 10 mg and 15 mg lines and all of its seltzers, auto-updates the 5 mg lines to a reformulated version, and invites subscribers to stock up before December. Vena's says subscriptions update to a reformulated version with the first December shipment.

What the provision says

Under section 781 of Public Law 119-37, a finished product falls outside the federal definition of hemp if it contains greater than 0.4 milligrams combined total per container of two things: total tetrahydrocannabinols, including tetrahydrocannabinolic acid, and any other cannabinoids with similar effects to a tetrahydrocannabinol, as determined by the Secretary of Health and Human Services.

That is one sentence, and the number in it is doing three jobs at once. Set the three brand pages against it and the figure they published is wrong in three separate ways.

The value is wrong. 3 against 0.4.

The denominator is wrong. A serving against a container.

And the composition is wrong, which is the one worth slowing down for. "Total THC" is not the cap. It is one of two limbs that add up to the cap. The second limb is not a list we can look up; it is a determination reserved to the Secretary of Health and Human Services, and we have not located one. We wrote that up in September at gethempdash.com/learn/rule-watch-container-level-thc-cap, and the reason we wrote it up is that we had published the one-limb version ourselves, on seven surfaces, before correcting it.

Reducing a serving does not act on a container total

This is arithmetic rather than law, and it is the part that reaches inventory.

A container that holds more than one serving contains the sum of its servings. So a change to the milligrams in a serving moves the per-serving figure and leaves the structure of a per-container total exactly where it was. Halve a gummy and a jar of them still totals whatever the jar totals.

The three pages describe a per-serving change. The provision they name as the reason is a per-container provision. We are not going to compute a multiple for any particular product, because none of the three pages publishes the count per jar in the reformulated version. But the direction is not in doubt: a reformulation aimed at a serving does not answer a limit written against a container, and a smaller serving in the same package is not progress toward a per-container number.

The loud error is the easy one

Here is what makes this morning worth recording rather than just correcting.

The 3 mg figure is being caught. A news channel published a comparison this morning that sets the three brands' own posts against the statute, does the unit math, and notes that the bills which would allow 5 mg per serving are not out of committee. That is good work and it is the right comparison.

We also asked the question in the direction that would embarrass the brands — whether the limit is 3 mg per serving or 0.4 mg per container — and got the correct answer straight back: there is no 3 mg per serving federal limit, and the measurement is per container.

So the loudest error in today's sweep can be caught with a single plain question.

Now the other one. Every source that corrected the unit this morning, including the careful one and including the direct question, still wrote the cap as "0.4 mg of total THC per container." One limb, named as if it were the whole provision. Nobody caught that today. We did not catch it in September either, until we read the enacted text and corrected seven surfaces in one day.

That is the shape worth carrying: the error everybody is arguing about is the easy one, and loudness is close to the opposite of difficulty.

The container is on the statute's own list of things that need defining

There is one more layer, and it belongs to the unit specifically.

The same section that sets the cap also carries an instruction. Within 90 days of enactment, the Food and Drug Administration, in consultation with other relevant federal agencies, was directed to publish four items. Three of them concern which cannabinoids count. The fourth is "additional information and specificity about the term 'container'."

Ninety days from enactment was February 10, 2026. The Congressional Research Service, in a report updated September 28, 2026, states that as of September 28, 2026 such a list has not been published. That is their statement on that date, and we are not going to extend it to today or characterise anyone's compliance with anything.

What it does mean is this. The denominator that three brands got wrong, and that a news channel spent a morning correcting, is one of the four things the statute itself flagged as needing more specificity than it had. We wrote about the other three items on this list last week, when the question was which compounds land where. This is the container limb of the same instruction.

What we are not going to tell you

Which date governs this cap. Section 781 sets its own effective date at November 12, 2026. A separate provision signed on September 2 says that until December 11, 2026 the section's amendments apply only to products described in two specific paragraphs — and this container cap is in a third paragraph, which that sentence does not name. What that omission does to this paragraph, in either direction, we declined in September and we decline now. Our reasoning is in the same article linked above. All three brand pages resolve it to December 11 without saying they are resolving anything.

Whether "until December 11" includes December 11. The text does not say.

Whether the second limb of the cap is empty. We could not find a determination. That is not the same thing.

Which specific compounds fall inside or outside the definition. We wrote about why that question has no published answer yet at gethempdash.com/learn/the-multiplier-lost-its-container and at the article on the four lists.

And nothing at all about what any agency will do, or about what may or may not be offered for sale, in Texas or anywhere else.

What to do with a number that arrives without a sentence

Three questions, and they would have caught every error above.

What is the denominator. A milligram figure means nothing until you know whether it is per serving, per container, per package or per unit of weight, and those are not interchangeable.

What is it measuring. If a cap adds two things together, a figure for one of them is not a smaller version of the cap. It is a different quantity.

Who published it. All three of these pages say "anticipated" or "expected" and then act as though the number were settled. A figure with a hedge in front of it and no citation behind it is a forecast, and a product line is a heavy thing to hang on a forecast.
