©2024 Keller and Heckman LLP

LieAnn Van-Tull practices food and drug law with an emphasis on food and drug packaging regulation and tobacco and e-vapor regulation. She advises domestic and foreign clients regarding compliance with global food and drug packaging requirements.

LieAnn assists companies in obtaining food contact clearances for their products in the United States (U.S.), Canada, China, South America, as well as the European Union (EU) and its individual Member States. She also provides guidance to clients on ways to establish a suitable regulatory status for products for which explicit premarket approval is not necessary. 

In addition, LieAnn advises foreign and domestic clients on tobacco and e-vapor regulation by providing state and federal legislative counsel to tobacco and e-vapor suppliers, retailers, distributors, and manufacturers. She also counsels clients on approaches to establishing clearances for tobacco products marketed in the U.S. 

Prior to joining Keller and Heckman, LieAnn served as regulatory counsel for the U.S. Food and Drug Administration (FDA), where she was a member of the lead counsel team on enforcement actions against companies that produce electronic nicotine delivery systems (ENDS). She also developed policies and programs involving matters affecting the regulation of the tobacco industry. Her experience at FDA allows LieAnn to assist Keller and Heckman partners in sorting through the complex and ever-changing e-vapor and tobacco regulations and explain them clearly and effectively to clients.

(Admitted to practice in Maryland only. Practice limited to matters before the FDA and matters ancillary thereto.)
