When it comes to U.S. airport security, federal law sets the foundation. The Transportation Security Administration (TSA) does not actively search for marijuana or cannabis-infused products, but if discovered, they must be reported to law enforcement. Under federal law, marijuana and certain cannabis-derived items remain illegal—except for hemp-based products that contain no more than 0.3% delta-9 THC by dry weight or are approved medications. In practice, this means travelers can generally bring hemp-derived cannabis SPF products through TSA checkpoints, provided they meet the THC limit. It’s always wise to carry products in their original packaging and ensure that labels clearly indicate they are hemp-derived.
Standard liquid rules still apply. Sunscreen—whether infused with cannabis or not—must follow the TSA’s 3-1-1 guideline: each container should be 3.4 ounces (100 milliliters) or less, and all liquid, cream, or gel items must fit within a single quart-sized bag. Larger bottles should be stored in checked luggage. Aerosol sunscreen sprays are permitted but also subject to volume restrictions.
Because sunscreen is classified as an over-the-counter drug by the U.S. Food and Drug Administration (FDA), labeling and formulation matter. The FDA has strict ingredient and labeling requirements for SPF products and continues to review how cannabis-derived ingredients fit into existing regulations. THC and CBD are not yet approved for use in over-the-counter drugs or cosmetics that make therapeutic claims. Therefore, cannabis SPF products should stick to providing UV protection without promising additional medical or therapeutic benefits. Consumers should look for clear ingredient lists and proper “Drug Facts” labeling to ensure compliance and safety.
International travel presents additional challenges. Even if a cannabis SPF is legal in both the departure and destination countries, carrying any cannabis-related product across borders can lead to confiscation, fines, or entry denial. U.S. Customs and Border Protection (CBP) and international agencies maintain strict prohibitions against transporting cannabis, regardless of THC content. For that reason, travelers are encouraged to leave cannabis-branded products at home when flying internationally and instead purchase SPF locally at their destination.
For domestic U.S. travel, a few steps can reduce risk. First, choose hemp-derived sunscreens that clearly state they contain no more than 0.3% THC. Keep products sealed in original packaging and pack them in small, TSA-compliant sizes. Avoid SPF products with strong cannabis scent or branding that could raise suspicion. Having a certificate of analysis (COA) from the manufacturer that confirms hemp content can also help if questions arise during inspection.
In short, cannabis SPF sits at the crossroads of skincare, cannabis regulation, and transportation law. For safe and hassle-free travel, consumers should stick to hemp-derived products, respect liquid and labeling rules, and avoid crossing international borders with any cannabis-labeled item.
