The 2026 Federal Hemp Rule Changes and What They Mean for CBG
On November 12, 2026, the legal definition of a hemp product in the United States changes. The 0.3% THC-by-weight test that defined the industry since the 2018 Farm Bill gives way, for finished products, to a much blunter instrument: 0.4 milligrams of total THC per container. That single number ends some product categories, forces others to reformulate, and leaves a third group — genuinely non-intoxicating cannabinoids like CBG — essentially untouched. Here’s what the law actually says, who it hits, and how to check any product in your cabinet against it. One note before we start: this is an educational overview from a hemp producer, not legal advice — businesses making compliance decisions should consult counsel.
How we got here: the 0.3% loophole
The 2018 Farm Bill legalized hemp as cannabis with no more than 0.3% Δ9-THC by dry weight. That definition was written for plants in a field, but it was applied to products on a shelf — and 0.3% of a heavy product is a lot of milligrams. A 100-gram edible could carry hundreds of milligrams of THC and still be “hemp.” Add THCA (which converts to Δ9-THC with heat) and hemp-derived Δ8, and by the mid-2020s an entire intoxicating-products industry — most visibly THC beverages — was operating under an agricultural definition, with estimates putting the hemp-derived THC drink market alone above a billion dollars a year.
Congress closed the gap in the appropriations law enacted in November 2025 (P.L. 119-37), with a one-year transition ending November 12, 2026.
What the new rule actually says
Three changes matter for anyone buying or selling hemp products:
The cap moves from percentage to milligrams. An ingestible hemp product may contain no more than 0.4 mg of total THC per container. Not per serving — per container.
“Total THC” counts the whole family. Δ9-THC, THCA, and other intoxicating THC analogs are summed. The era of “compliant” products built on THCA or Δ8 technicalities ends with them counted like any other THC.
Synthesized cannabinoids are excluded from the hemp definition. Intoxicating cannabinoids manufactured by chemical conversion rather than expressed by the plant fall outside legal hemp entirely.
To put 0.4 mg in perspective: a typical hemp THC seltzer carries 5–10 mg per can — 12 to 25 times the new limit. This isn’t a trim; it’s a redefinition that separates intoxicating products from everything else.
Who is affected — and who isn’t
Ends or reformulates: THC beverages, high-THC gummies and edibles, and THCA flower marketed as hemp. Their producers are exiting, reformulating below the cap, or moving into regulated marijuana channels.
Needs a hard look at the COA: full-spectrum products. “Full-spectrum” means trace THC by design, and whether a given bottle clears 0.4 mg total depends on its concentration and container size — some formulations pass, others don’t. The label won’t tell you; the lab report will.
Effectively untouched: non-intoxicating cannabinoids with nothing to count. A CBG isolate testing non-detect for every THC variant contains 0.0 mg of total THC per container of any size. Same for broad-spectrum products engineered to remove THC — provided the COA proves the removal actually happened.
Where CBG stands
CBG is not THC, is not intoxicating, and is not what this law is aimed at. The only question for any CBG product is what else is in the bottle — and that’s a question a Certificate of Analysis answers in one panel. Our isolate’s COA reads non-detect across the full THC family (Δ9, Δ8, THCA, and the minor variants), which is also what lets it meet the strictest state standard we operate under: Kansas requires 0.00% THC for products sold in-state, a bar higher than the incoming federal one. Products built to the Kansas standard were, in effect, 2026-ready years early. If reading a THC panel isn’t second nature yet, our COA buyer’s guide walks through one line by line.
What to do before November 12, 2026
If you use hemp products: pull the COA on anything you rely on and multiply total THC concentration by container size. Under 0.4 mg, nothing changes for you. Over it, expect that product to change or disappear — and know that its non-intoxicating equivalents (CBG and CBD isolates, true broad-spectrum) carry on as before.
If you make or sell products: the transition window is for auditing your catalog against total-THC-per-container, reformulating where needed, and tightening supplier documentation — with counsel, since enforcement details are still being finalized ahead of the effective date. Sourcing ingredients that test ND for the entire THC panel is the cleanest path to a catalog with nothing to count; that supplier-vetting checklist is in CBG for Formulators.
Frequently asked questions
What is the 2026 federal hemp rule?
A provision of federal law (P.L. 119-37, enacted November 2025) that redefines legal hemp products. Starting November 12, 2026, ingestible hemp products are limited to 0.4 mg of total THC per container — counting Δ9-THC, THCA, and other intoxicating THC variants together — replacing the old 0.3% Δ9-THC-by-weight test as the operative standard for finished goods.
Does the rule ban CBG?
No. CBG itself is not THC and is not restricted by the rule. What matters is the total THC riding along in a CBG product — a CBG isolate with a full non-detect THC panel has nothing to count against the 0.4 mg cap.
Will hemp THC drinks still be legal?
In their current form, most will not — typical hemp-derived THC beverages carry several milligrams of THC per can, far over the 0.4 mg-per-container cap. Producers are reformulating, exiting, or pivoting to non-intoxicating cannabinoids.
Is Kansas affected?
Kansas already holds a stricter line: products sold in-state must test 0.00% THC. Anything compliant in Kansas today clears the federal 2026 cap with room to spare — the new federal floor is effectively catching up to where Kansas has been.
How do I know if a product will clear the rule?
Read its COA and do the arithmetic: total THC concentration times container size. If the THC panel is non-detect across the board, the answer is zero milligrams and the product clears the cap by definition.
The short version
The 2026 federal hemp rule replaces a percentage loophole with a hard ceiling: 0.4 mg total THC per container, all THC variants counted, effective November 12, 2026. It ends the intoxicating-hemp era, puts full-spectrum products on notice, and changes nothing for cannabinoids with a clean THC panel. The winners were decided years ago, in the lab: products with nothing to count have nothing to fear — and the COA is how you tell which is which.
Kaw Valley Cannabis is a family-owned, vertically integrated hemp brand in Lawrence, Kansas, specializing in cannabigerol (CBG). Our products are built to Kansas’s 0.00% THC standard — stricter than the incoming federal cap — with a full non-detect THC panel on every Certificate of Analysis.
