Hemp, just like (public policy defined) marijuana, contains CBD. CBD derived from marijuana is federally prohibited, but CBD derived from hemp can be legal in some instances. According to U.S. Customs and Border Protection imported hemp products (including hemp derived CBD products) are legal as long as they ‘do not cause THC to enter the human body are therefore legal products.’ CBD products made from hemp that are imported from overseas are almost always of low quality, often being made from hemp paste from China. These products, while legal, are basically modern-day snake oil and are not something I would recommend consuming.
Domestic hemp, and the products made with it, are federally prohibited but with exceptions. Section 7606 of the Agricultural Act of 2014 allows legal hemp cultivation in states that have legalized hemp at the state level via a pilot program or research program. CBD products can be made from the legally grown domestic hemp, and sold inside the state that they were made in. The same can somewhat be said about CBD products made from state-legal marijuana plants, in that if they are sold in the state they were made, there are some federal protections in place via the Cole memo. However it’s worth noting that the current United States Attorney General has stated that marijuana prohibition remains in effect in all 5o states, seeming to disregard any protections outlined in the Cole memo.
