Import Permits
CDC: a permit is required to import etiologic agents of human disease and any materials, including live animals or insects, that may contain them. Unsterilized specimens of human and animal tissues (such as blood, body discharges, fluids, excretions or similar material) containing an infectious or etiologic agent require a permit in order to be imported.
APHIS: a USDA veterinary permit is needed for materials derived from animals or exposed to animal-source materials.
