How long is the CDC import permit valid once it has been issued?
There are two types of import permits that are issued to importers requesting to import and transport etiologic agents, hosts, or vectors of human disease: Multiple Use Importation permits and Single Use Importation permits. The Multiple Use Importation permits are issued for twelve months and Single Use Importation permits are issued for six months depending on the importation into the United States.
