A provision embedded within recent legislative changes has raised concerns among businesses in the hemp supplement sector. The amendment revises key language from the 2018 farm bill, which previously defined “hemp” as cannabis containing no more than 0.3% delta-9 THC by dry weight. This adjustment could invalidate thousands of federal trademark registrations and disrupt the $28 billion industry.
The 2018 farm bill allowed hemp products with THC levels below 0.3% to be legally sold, creating a framework that enabled the rapid growth of THC-infused supplements. Brands leveraged this by registering trademarks that explicitly linked their products to the farm bill’s definition. Over 3,000 federal registrations now include variations of the delta-9 language, with thousands more pending.
However, the new amendment, effective November 12, 2026, narrows the legal definition of hemp. It excludes any product with THC concentrations exceeding 0.3% or 0.4 milligrams per container. Most consumable hemp supplements, including popular delta-8 gummies, far exceed these thresholds. Once the amendment takes effect, their production and sale may become unlawful under federal law.
This shift introduces significant challenges for trademark owners. Federal registrations require proof of lawful use in commerce. If the underlying products are no longer legal, brands may struggle to maintain registrations, renew trademarks, or enforce rights. The U.S. Patent and Trademark Office (USPTO) has not yet clarified whether existing registrations will be canceled or rejected after the effective date.
Beyond trademarks, the amendment threatens the broader industry. While many states have legalized THC products, federal law could override state regulations under the Supremacy Clause. This creates a fragmented regulatory environment that complicates interstate commerce and raises questions about preemption.
Businesses reliant on the farm bill’s delta-9 safe harbor must now evaluate their compliance strategies and trademark portfolios. Proactive steps, such as reviewing product formulations and updating registrations, will be essential to navigating the impending legal landscape. The outcome of this shift could reshape the future of hemp-based commerce in the U.S.
The legal landscape is shifting fast, and the stakes are high. A single oversight could cost millions in lost revenue and brand reputation. By prioritizing trademark monitoring, companies can avoid costly disputes and protect their market position. The future of the hemp industry depends on adaptability, and IP Defender is here to help.
