The legality of CBD products also varies from state to state within the US, depending on the composition of your product. The notation on the TSA’s website about medical marijuana and CBD products gotten from marijuana now reads "Possession of marijuana and certain cannabis infused products, including some Cannabidiol (CBD) oil, remain illegal under federal law. TSA officers are required to report any suspected violations of law, including possession of marijuana and certain cannabis infused products.”
On the other hand, products that contain hemp-derived CBD are legal as long as it is produced within both State and Federal regulations. The FDA clarifies this with their statement “Products/medications that contain hemp-derived CBD or are approved by the FDA are legal as long as it is produced within the regulations defined by the law under the Agriculture Improvement Act 2018.”
You should only travel with hemp-based CBD – preferably isolates – and ensure that your product complies with the appropriate rules and guidelines bordering the use of CBD at your destination.
