Quick answer: Yes, hemp-derived CBD is federally legal today if it contains no more than 0.3% delta-9 THC by dry weight. But federal law is changing. A November 2025 funding law redefines hemp so that final products with more than 0.4 mg total THC per container fall outside the federal definition. The change was set for November 12, 2026 and has been moved to December 11, 2026, unless Congress acts again.
Key takeaways
- The 2018 Farm Bill legalized hemp with up to 0.3% delta-9 THC.
- The new definition counts total THC (including THCA) and adds a per-container cap.
- Many full spectrum products may exceed 0.4 mg total THC per bottle.
- THC-free products are the most likely to remain compliant.
What is changing
The new federal definition measures total THC rather than only delta-9 THC, so THCA counts. It also sets a cap of 0.4 mg total THC per container for final hemp-derived products, and restricts synthesized cannabinoids. Hemp plants above 0.3% total THC also fall outside the definition.
What it means for CBD products
A 30 mL full spectrum oil at 0.3% THC by weight can contain well over 0.4 mg THC in the bottle, so many full spectrum products would be affected. Broad spectrum and THC-free products with non-detectable THC are best positioned. See THC-Free CBD Oil Explained and Full Spectrum vs Broad Spectrum CBD.
What could still change
Bills have been introduced to set a different THC threshold and create a federal regulatory framework, and the effective date has already moved once. States also set their own rules, which can be stricter or looser. Check your state’s regulations and watch for updates.
What we recommend
If you want a long-term routine with the least legal uncertainty, consider THC-Free CBD Oil. We will update this article as the rules evolve.
A short history of hemp law
For decades, all cannabis, including hemp, was treated as a controlled substance at the federal level. The 2014 Farm Bill allowed limited hemp research programs. The 2018 Farm Bill removed hemp from the Controlled Substances Act, defining it as cannabis with no more than 0.3% delta-9 THC by dry weight. That opened a national market for CBD, but it also created a loophole: products could contain meaningful amounts of THC per serving, or intoxicating cannabinoids such as delta-8, while staying under the dry-weight limit. The new definition is designed to close that gap.
What “total THC” means
Delta-9 THC is the main intoxicating form. THCA is its raw acid form, which converts to THC when heated. Measuring total THC counts both, typically by adding delta-9 THC to a calculated share of THCA. Products and plants that passed a delta-9-only test may fail a total THC test.
The math of 0.4 mg per container
Consider a 30 mL bottle of oil weighing roughly 27 grams. At 0.3% THC by weight, that bottle could contain around 80 mg of THC. Even at 0.01%, it would contain about 2.7 mg, well above 0.4 mg. That is why most full spectrum oils are expected to fall outside the new definition unless they are reformulated, and why products with non-detectable THC are best positioned.
How states fit in
States can set their own rules for hemp and CBD, and many already do, from age limits to labeling requirements to bans on certain products. When the federal change takes effect, interstate shipping, banking and retail may be affected even where a state still allows a product. Check your state’s agriculture department or cannabis regulator for local rules.
What consumers should do now
Review the COA for any CBD product you use and note its total THC. If you rely on a full spectrum product, consider whether a broad spectrum or THC-free option would meet your needs. Keep an eye on news about the effective date, since Congress has already moved it once. When in doubt, ask us; we follow these changes closely.
What we are watching
Pending bills that would set a different THC threshold and create a federal framework for hemp products, any further changes to the effective date, and guidance from federal agencies on testing and enforcement. We will update this page as rules change.
Quality checklist before you buy
Whatever product you choose, check for CBD listed in milligrams per container and per serving, the extract type (full spectrum, broad spectrum or isolate), a batch number, and a recent third-party certificate of analysis that matches that batch and shows passing results for THC, heavy metals, pesticides and residual solvents. Store CBD in a cool, dark place with the cap tightly closed, and use it before the expiry date.
The bottom line
CBD from hemp remains federally legal today, but the rules are about to tighten. The new definition counts total THC and caps finished products at 0.4 mg THC per container, which will affect many full spectrum products when it takes effect, currently scheduled for December 11, 2026. Dates and limits could still change, and state laws add another layer. The most future-proof choice is a product with non-detectable THC, backed by a current lab report, and we will keep this page updated as the law evolves.

Frequently asked questions
Is CBD federally legal right now?
Yes. Hemp-derived CBD with no more than 0.3% delta-9 THC by dry weight has been federally legal since the 2018 Farm Bill, though state rules vary.
What is changing in federal hemp law?
A November 2025 federal funding law redefines hemp. When it takes effect, final hemp products with more than 0.4 mg total THC per container will fall outside the federal definition.
When do the new hemp rules take effect?
The change was set for November 12, 2026, and a later funding measure moved it to December 11, 2026. Congress could change the date or limits again.
Will THC-free CBD still be legal?
Products with no detectable THC are the most likely to remain within the new federal definition, but labeling, testing and state rules still matter.
Will full spectrum CBD be banned?
Many full spectrum products are expected to exceed the 0.4 mg per-container limit, so unless they are reformulated or the law changes, they would fall outside the federal hemp definition.
Can I still buy CBD online after the change?
Products that meet the new definition can still be sold, but shipping, payment and marketplace policies may change. Check with your supplier.
Does the new law affect CBD for pets?
The new definition applies to hemp-derived products generally, so pet products containing THC above the limit would be affected too.
