2020 . By this time , manufacturers needed to submit a large amount of paperwork with scientific evidence , or at least sincere plans to conduct the relevant research on any given product . Until a product has received a PMTA , it cannot be legally sold in the U . S . The Vapor Technology Association ( VTA ) had asked for a final extension earlier this year , due to concerns about the ongoing pandemic , along with a lack of clarity for which materials manufacturers actually needed to provide . This request was denied by the FDA , who said : “ Any additional delay would impede FDA ’ s critical public health priority to promptly require submission of Premarket Tobacco Applications .” Now , with an expired deadline and overwhelming number of applications , pressure is mounting on the FDA to be more transparent with the process , to guide businesses and consumers and help enforcement of the rules . Sen . Durbin has long been an outspoken critic of the vaping industry . In the past , he has called for fees to be enforced on manufacturers and importers , which could jeopardize independent businesses . Last year , he called on acting FDA Commissioner Dr . Ned Sharpless to ban all flavored vapor products other than tobacco . The FDA ’ s Mitch Zeller , director of the agency ’ s Center for Tobacco Products , confirmed in September that all PMTAs would be available in a database format . While vapers and businesses wait for this to happen , it ’ s the vaping community who have started to document progress .
