What You Need To Know
- U.S. transits are classified as shipments presented to a U.S. port of entry for conveyance purposes to then be transported to a destination country shortly after.
- Please note that any animals and their germplasm transiting the United States must not transit countries with questionable disease statuses prior to reaching a U.S. port of entry.
- All transits require a contingency plan. Submit your contingency plan with your permit application (VS 17-129 (211.74 KB)) to laipermits@usda.gov. To submit an import permit electronically, visit APHIS eFile.
- If you are applying to import live animals, semen, and embryos, you may submit applications by email to laipermits@usda.gov.
