The "Family Smoking Prevention and Tobacco Control Act" issued by the US government in 2009 granted FDA the power to regulate all tobacco products, but only required FDA to control cigarettes, cigarette tobacco, smokeless tobacco and self-made cigarettes. In order to regulate all other products, FDA must issue a new rule that "considers" these products to be within FDA's regulatory authority.

The structure of electronic cigarette is mainly composed of cigarette rod and cigarette oil. The entry of electronic cigarette into the United States market needs to consider the safety certification UL certification and FDA test. The safety of electronic cigarette should consider such safety factors as heat and scald, harmful substances of oil smoke, overheated ignition of electronic cigarette battery, overheated short circuit of charger, etc. UL is the certification of safety regulations in the United States, and passing the FDA test is to prove that the product has passed the requirements of the United States Food and Drug Administration.


The UL certification standard of electronic cigarette is UL8139, which is customized by the American National Standards Association and the Canadian Standards Committee. The UL8139 test report certificate of electronic cigarette can be used for customs clearance, including the UL8139 certification required for products entering large supermarkets such as Wal Mart, and also required for sales on Amazon in the United States.
