In August, the U.S. Food and Drug Administration (FDA) issued a new proposed rule that would require importers of electronic nicotine delivery system (ENDS) products to provide an FDA-issued submission tracking number (STN) to U.S. Customs and Border Protection (CBP) for imports of such products. This rule could result in the denial of entry for ENDS imports for which the manufacturer has not submitted a premarket tobacco product application (PMTA) to FDA.
